Time Travel

By Cyprien CHARRA

DID YOU

KNOW ?

TIME TRAVEL IS

FEASIBLE !

WITH SOME FAKE TIME MACHINE

NOT

BUT

THANKS TO …

RELATIVITY

299 792 458 m / s

THIS IS THE SPEED OF LIGHT

IF YOU MANAGE TO GO FASTER

299 792 458 m / s

YOU WILL GO BACK

TO THE PAST*

*But probably not with Michael J. FOX

THEN, WHAT USE IS

WE CAN USE IT TO

SEE THE PAST

HOW ?

LOOK

UP

WATCH

THE

STARS

WE SEE THE LIGHT OF THE

WITH 8 MIN OF DELAY

WHICH MEANS… IF IT " turns off " NOW

WHICH MEANS… IF IT " turns off " NOW

WE WON'T NOTICE IT BEFORE THE END OF THE PRESENTATION

THE FARTHEST WE EVER SAW * IS A BLACK HOLE

6 MILLION LIGHT-YEARS AWAY*IN JANUARY 2010

WE NOW SEE THE GALAXY NGC 300

HOW IT WAS

6 MILLION YEARS BEFORE

WHAT ELSE

?*

*WITH RELATIVITY …

IF YOU GO

FASTER

YOU WILL LIVE

"LONGER"

WHY ?

WITH TIME RELATIVITY

A CLOCK IN A SATELLITE AT HIGH SPEED

GOES SLOWER THAN THE

SAME CLOCK ON EARTH

IF YOU LIVED AT 80 MILLION KM/H AROUND EARTH, YOU WOULD LIVE

3.6 TIMES LONGER

BUT ON EARTH 250 YEARS WOULD HAVE PAST

ISN'T THERE ANY

SAFER WAY ?

WELL …

YEAH !

WITH THESE

TOOLS !

FOSSILS

TELL US A

LOT ABOUT

OUR PAST

AND THE UNDERSTANDING

OF OUR ORIGINS

TO SUM UP :

IF YOU WANT TO SEE THE PAST

Go faster than the light

Watch the stars

Dig the ground

TO SUM UP :

IF YOU WANT TO SEE THE FUTURE

Go faster than other people

Just wait for it !
