According to Albert Einstein, to travel into the future, we must approach the speed of light. To trave

into the past, we must surpass the speed of light.

The current record holder for time-traveling is Sergei Krikalev. He has traveled about 337 million

miles in orbit at some 17,450 mph reaching a grand total of 0.02 seconds into the future. This

means that from now on, he takes a step two hundredths of a second before you see him take it.

Future time-travel is possible, as youll see explained.

But no one has traveled into the past. No one will do so unless we break the light barrier, as the

following proofs will show you.

2/18

The term gets its name from Robert Heinleins short story By His Bootstraps. The phrase pullyourself up by your bootstraps refers to a self-sustaining process that requires no external

stimulus to exist.Alternate history is a popular concept of time travel and centers on the premise of changing history

whether accidentally or deliberately, while traveling back through it. One counter to this is the claim

that any change a time traveler makes to history is precisely what was always supposed to happen

(see #3).But an aspect of the paradox that this counterargument does not address is the simple fact that

any object traveling through time is itself aging normally. A person cannot travel faster than light in

order to remain forever young; he may return to Earth after 10 years while Earth has aged 1,000, bu

he is still 10 years older, and eventually will die. The same goes for inanimate objects. Say you

misplace your Oscar acceptance speech, so you get in your time machine and travel back 30 minute

to a time when you still know where the sheet of paper is, retrieve it, and return to the future in th

nick of time to deliver it for your Lincoln performance. This is #3 on this list.

But to the point: any object traveling through time, for the duration of the trip, no longer impresses

itself on history. After 100 million years, that sheet of paper has worn to dust, as has the traveler.

But the show must go on, and the Oscar goes to the same person, who now accepts it without the

speech, because it no longer exists outside history to return to him in the future. Now lets consider the concept of information itself traveling back through history. Say you invent

the time machine and use it to travel back 1,000 years. You share the knowledge of time travel with

the people of that time, and they use it to invent the time machine. 1,000 years later, you invent the

time machine, go back in time, and so on. Now we have a problem: since there cannot be more than

one origin of something, the invention of time travel effectively has none, and this application is jus

as undefinable as dividing by zero.

9Weak Cosmic Censorship Hypothesis


3/18

Stephen Hawking has spent his career working with black holes, and most of what we know aboutthem is based on his work. The surface of a black hole is the event horizon, and once any object

crosses this and enters the hole, it no longer exists in our spacetime continuum. It is drawn by

extreme gravity into an infinitely thin strand of energy called a singularity. Hawkings work theorizes that only the terrific energy of a black hole can create a singularity. The

weak cosmic censorship hypothesis asserts that there can be no singularity unhidden by a black

hole, and thus, no singularity can ever be observed. The singularity is a major talking point of

cosmology, because one theory of black holes paints them as gravitational pulls so strong that they

impart faster-than-light speed to any object entering them. The singularity is the engine of a black

holes gravity. So if a spacecraft wanted to break the light barrier, it would need only to travel through a black hole

and upon emergence from the other side would still be traveling at this speed namely, jump-

starting a spacecraft past light speed so it can return to Earth at some point in the past. But no object can survive a black holes singularity. Here, matter may actually be destroyed,

apparently violating the law of conservation of mass. Hence, until singularities are proven to exist

outside black holes, this method of traveling into the past is impossible.

8The Chronology Protection Conjecture


4/18

This one was dreamed up by Hawking himself, and there is a LOT of mathematics without numbersinvolved in it. In a nutshell, the conjecture requires that there be no such thing as a closed timelike

curve. A CTC is the closed path of any object as it travels through 4-dimensional spacetime; if the

path brings the object back to its starting point, the path is said to be closed. No mathematical theory can yet predict if CTCs exist. If their existence is demonstrated, Hawkings

conjecture is demonstrably false, and travel into the past may be possible, probably via the next

entry. If CTCs do not exist, then the conjecture is true, and historians throughout the Universe are

protected, as Hawking says. Our most immediate chance of discovering whether CTCs exist lies in quantum gravity, the branch

of mathematics devoted to combining all four forces of the Universe into a single blueprint that can

describe all physical laws on both the macroscopic and subatomic scales. The four forces include:

the weak force, which holds electrons in orbit around nuclei, initiates hydrogen fusion in stars, and

causes the radioactive decay of all subatomic particles; the strong force, which holds protons and

neutrons together as nuclei; electromagnetism; and gravity. The General Theory of Relativity

reconciles all but electromagnetism; quantum gravity, using a different approach, reconciles all but

gravity. Until quantum gravity is fully explored, CTCs can only be hypothesized, and in their absenc

traveling into the past cannot be done.

7Wormholes Disobey the Laws of Physics


5/18

All our understanding of time travel is based on what we know of the physical properties andinteractions of the Universe. We have devised a branch of mathematics currently separate from

physics to describe the laws of physics on a microscopic scale, and we call it quantum physics. This

branch strongly theorizes the existence of Einstein-Rosen Bridges, named after the two scientists

most responsible for our understanding of them.

They are more popularly called wormholes, and they are holes that have ripped through the fabric o

spacetime. If we could make use of them, the shortest distance between two points would no longe

be a straight line but zero, caused by puncturing spacetime at the point of origin and at the point o

destination, just like poking holes through a sheet of paper; then spacetime is effectively folded unt

the two points overlap, and the traveler passes through from A to B, and spacetime is unfolded to

its original state. No physical movement occurs, but the destination may be at the other end of the

known Universe, and the spacecraft would have neither approached, nor surpassed the speed of

light, but simply teleported. This seems to allow the possibility of travel into the past by avoiding the speed of light altogether,

but what it does not account for is what goes on inside a wormhole. Physics has no idea, except to

say that the laws of physics do not exist as we know them, or do not exist at all, inside wormholes. we attempt to comprehend travel through wormholes in our terms of physics, then we are not

addressing the issue to begin with, and have not yet left square one.

6No Tourists from the Future


6/18

Lets take a short respite from the math. A theory held firmly by hundreds in the highermathematics community, including Stephen Hawking, is that we already have verifiable proof that

there can be no faster-than-light travel: there is no one from the future walking among us right now

at least as far as we know. To this end, meetings have been scheduled and attended by academics

and plain old fans of science fiction, in which they sit and converse on the subject while waiting for

visitors from the future to show up at the meetings. The idea is that in the future, people will know

of these meetings in the same way that we know about WWII; its history to us. So if time travel

should ever become reality, the travelers ought fairly to return to waiting people in the present and

prove it. So far, of course, this does not appear to have happened, and since we speak here in terms of the

entirety of the future from now until the end of time, there should be quite a lot of travelers from

many points throughout the future showing up at many points throughout their past. A fun

criticism of this is the question, Why in the world would anyone want to visit our time? 1

September 1939 makes sense, but today? If they were to warn of us something, what would it be?

Would they return with some brilliant philosophy about how to effect real world peace?

Imagine: you can travel to any point in the past you like. What would you like to see? 90% or more of

prospective travelers would like to see if Jesus Christ really existed. But would you take it upon

yourself to return to now and avert the imminent war between Israel and Hamas? No one has yet.

5The Twin Paradox

This paradox deals more properly with travel into the future. It involves two newborn, identicaltwins, one who stays on Earth, and one who travels to Proxima Centauri, the nearest star, 4 light

years away. If the spacecraft travels at 80% the speed of light, which amusingly seems more

realistic, the round trip will take 10 years. That means the twin on Earth will be 10 years old when

his brother returns. But on the spacecraft, the crew observes Promixa Centauri and Earth also moving with relation to

the craft, and this causes Points A and B to shorten to a distance of 2.4 light years, not 4. Each leg o

the journey will take 2.4 light years divided by the speed, 80% of the speed of light, for a duration of

years one way, 6 round trip. Thus, the twin onboard will have aged 6 years in the same relative span

of time. This much is not logically impossible. What is impossible is the effect of one twin traveling 101% or more of the speed of light. This would

at least according to this scenario as we understand it, cause him to travel into the past and cease

to exist, i.e. disappear from onboard, and not return to his brother on Earth.

4E = MC Squared

The most famous equation in the history of mathematics describes the relationship of energy andmass. In 1942, it was notoriously seized upon as a great idea for a powerful new weapon. Einstein

had no idea it could be used to build a bigger, better bomb, and wept when Enrico Fermi and Rober

Oppenheimer explained what was going on at Oak Ridge, Tennessee. Aside from explaining how much energy is contained in matter of any size, it also provides an

exploration into what happens to mass when it travels faster. The faster something travels, the

more energy is required to sustain its travel. As an object approaches the speed of light, it

approaches infinite mass, and thus requires infinite energy to continue propelling it forward. This does not prohibit traveling into the future, since all an object has to do is approach the light

barrier. You approach it when you walk into the kitchen to get a beer. The distance into the future

you have traveled is too insignificant to matter. But technically you gain an equally insignificant


9/18

amount of mass. The energy required to propel a large object, like a spacecraft, any meaningful

distance into the future, as that meaning relates to our frame of reference, would be greater than o

equal to the energy currently in VY Canis Majoris, the largest star we know of. But to break the light barrier would cause the traveler to go into the past, and this would require

infinite, and then greater than infinite, energy. This is impossible to achieve.

3 Temporal Causality Loop

This is a paradox as well, and deals with one specific scenario: the invention of the first timemachine. The inventor travels back in time in an effort to make his grandfather and grandmother fa

in love, only to accidentally kill his grandfather (see #2). Now, desperate to exist in the future, he

sleeps with his future grandmother and fathers his own father, thus enabling himself, in the future

to travel back in time and father his father again. This paradox is illogical because it describes an effect in the future occurring before its cause in the

past. Suppose you were to travel back in time to before the Big Bang, somehow cause the Big Bang

and thus create the Universe. In terms of fate, this would happen in order to enable you, 13.5 billion

years later, to invent the time machine and travel back to create the Universe so the time machine

could be invented. It is fundamentally insensible.


10/18

2Temporal Paradox

This is essentially the negative version of #3, and is also called the Grandfather Paradox. Travelinginto the past must be logically impossible because it would enable you to go back in time and kill

yourself. But if you die, how will you travel into the past from the future to kill yourself? Critics,

especially science fiction fans, are quick to point out that our understanding of mathematics

expands every day thanks to people like Newton, Einstein, Hawking, and Michio Kaku, and with it

comes an expanded understanding of the logic involved in time travel scenarios. The best current counter to the temporal paradox is the Multiverse, which describes an infinite

number of yous doing an infinite number of things at an infinite number of points throughout your

life. You may be stabbed in a bar fight at 100 years old in another Universe, but die of cancer as a

child in this one. Imagine a Universe without Listverse. Our current understandings of quantum

mechanics and quantum physics lends strong credence to the possibility that the Multiverse is areality. It would negate the temporal paradox, and several others, allowing you a future after you

have killed yourself. But there is still no fully formed theory of the Multiverses existence, and until

there is, this paradox stands.

1No Unified Field Theory


11/18

Frankly, all the previous entries are based more in terms of logic than in pure mathematics,precisely we can only surmise everything related to time travel according to our very superficial

comprehension of it. Albert Einsteins life work centered on what we now call Relativity. He

postulated two theories of it, but the next step, an infinitely more important one, is to unify the

General Theory of Relativity with electromagnetism. Einstein died working on this, and todays

eggheads have taken only baby steps forward. The highest form of mathematics to date is called

M Theory, which is not even fully described yet. Its practically a religion to mathematicians,because so little is understood about it that some dont believe in it. It identifies 11 dimensions in the Universe, not just 4, and its champions expect that it can unite th

5 differing string theories that preceded it, and take what may be the only step left beyond: a

unification of the physical properties and laws of all 4 forces of the Universe. M Theory seeks a

common ground between General Relativity and Quantum Gravity with the goal of combining all 4.

To do so is to take a mathematical look at how the Universe appeared, and how it acted, when it wa

still an infinitely small point packing all the matter and energy that exist in it today. To comprehend

such physics would enable a mathematical comprehension of how to manipulate spacetime itself

and pre-vert to a time in the future or revert to a time in the past. Until someone unifies all 4 force

into a single physical quantity with a value for each point in spacetime, we arent going any-when.

Quoting the introduction "This means that from now on, he takes a step two hundredths of a

Vintage is correct. Future time travel is really just time going slower for you than for

everyone else due to the high speed at which you are traveling, you are not literally ahead of

everyone else... once you stop traveling at or near the speed of light time would resume to

normal for you, and you would have aged less hence "time travel". The closer you approachthe speed of light, the slower time passes for you, so the more pronounced the "time travel"

effect will be.

I sprained my brain

I feel stupid

etc etc

Thank you for your cooperation.

Mr. Blank

You only had to say you were stupid in one way, ni99a. Actually, you didn't have to say

it at all since we all knew it anyway. Thanks for playing though.

thearchitect

It take a lot of energy do understand those texts . i like science but i'm not a scientist. It's very

complex.

The Annoyed Elephant

There is so much fail in this list that I can't even begin to start (mostly thanks to a rotten cold

at the moment). Meanwhile, I'll offer a single correction to #4: YV Canis Majoris, while a large star, i

no longer believed to be the largest. That honor goes to NML Cygni, however, both KY Cygni and

Westerlund 1-26 may be significantly higher.

6 2

Timothy53

OK, so, how does that negates the fact that to approach the speed of light significantly

enough to affect time one would need more than the energy in the *once* largest star knowReally now, is the difference significant? "Mr. Sulu, we can now go warp factor one because

while we couldn't use YV Canis before, now that NML Cygni, KY Cygni, and Westerlund 1-2

are now known, we *can* use it! Woo Hoo!"

stephen-lopez

This comment made me laugh haha, Timothy is correct... the fact that a larger

star may have already been found is irrelevant. Point is: we don't have the technolog

capabilities or even the slighest clue as how to harness the power of a star many mtimes larger than our own sun. Oh and as a side note: the size of Canis Majoris is st

debated by experts from 600 to about 1400 solar radii, its exact size is unknown due

it diminishing in size causing the outer layers to no longer be gravitationally bound,

which brings up the problem of what is considered the surface of the star (wiki)... it i

not debatable that Canis Majoris is a beast of a star though!

Mr. Blank

I had not heard about those newer ones. I think I have some Googling to do. 1

Alrighty, now that I've half understood some of it....you all need to watch this video so you too

can 1/2 understand it. You that aren't mathematicians or theoretical physicists. This explains the

multiverse, 10 dimensions, and helps you to wrap your head around the rest of it.

http://www.youtube.com/watch?v...

A little question for Flamebaby - somewhere at the beginning of the list the statement was made th

time changes only for the observer. The guy in the ship doing all that speeding around? His aging e

remains constant. But then in the twin paradox you have him poofdisappearing. I don't get it.

Good list by the way (at least I think it is).

Mr. Blank

I saw that video years ago, Mom and was considering looking for it when I saw you

had already posted it. Thank you for saving me the trouble.

FriendlyBob

Time dilation says that when you're travelling faster than your observer, your time will

slow down with respect to how fast you're going. For you it will appear to go normal, but

someone looking into you vehicle ( if you were going exceptionally fast, atleast 30% the spe

of light) would see you move in slow-motion, and you would see them moving super fast. T

faster you go the slower time goes, and when you would go over the speed of light theoretia

you would go back in time.

I'm going to have to watch that several times. I still don't quite understand it. But it was

really interesting. Thanks for posting it.

Bzzzp

I like to remind people that say we can not travel faster than light, they called it the soundbarrier because it was determined that you could not travel faster than the speed of sound. Even th

reasoning is similar, If you looked at it mathematically, drag approaches infinity as you approach th

speed of sound.

I did enjoy the list

Timothy53

The so-called "sound barrier" was never, ever an issue of physics. It was always amatter of engineering. It was well known the sound of a whip cracking was the tip of the whi

exceeding the speed of sound and creating a mini sonic boom. One fear was that the sonic

boom itself would destroy the aircraft. There was never any doubt that an aircraft could be b

that would go faster than the speed of sound, only that it would hold together. Once the

engineering problems were solved, Chuck Yeager did it.

Fantastic list Flamehorse. I like the theory of multiuniverses. Or at least many more

Flamehorse proves once again he's a retard who writes bad lists in the guise of deep lists.

Mr. Blank

Armin proves his flaming love for Flamehorse once again.

Mr. Blank

I approve this message.

Indubitably my dear Watson.

As for the $2,000 contest for this month? Well, I believe you have your rightful winner right

here!

Mr. Blank

Nice list, Flamehorse, but the editor missed some errors again.

In item nine, the event horizon is not the surface of a black hole. It is simply the point at which in-fal

matter can no longer escape. The "strand of matter", as you called it, is also not a singularity. The

singularity is the black hole's core, the monster in the machine so to speak. The process you

described though is called "spaghettification". Yes, that's the technical term.

In item eight, "combining all fource forces"; well, this one is obvious.

In item two; "logic involved time travel" is also an obvious, and understandable, error.

However, again, nice list. i didn't know about one or two of these, so it made for a highly entertainin

read. If only Jamie could get his editor to do their job better so that I could stop being distracted mid

sentence all of the time... I blame it on my wife. Never marry an English major.

Thanks - I have corrected the last two errors - the first I am not equipped to correct asI don't know enough about the subject.

Mr. Blank

You're welcome, Jamie. I know I'm a bit snarky on the subject, but the errors

are very distracting.

As for the subject matter, heck, just use Google or Wikipedia. Just be sure you Goo

"gravitational singularity" and such. Otherwise you'll likely get hits featuring Vernor

Vinge and Ray Kurzweil.

Or we could just wait for Flamehorse to get around to checking on it...

Blight

Holy crap, no one cares. Go blow yourself already.

Mr. Blank

Jamie cared enough to both correct it and respond. I'd say that

disproves your idiotic opinion. Now, I suggest you find a reputable therapist to

look into you infantile attention whoring.

Blight

Are you done blowing yourself? FFS. Of course Jaime is going to

correct it, he owns the site dipshit.
