Time Travel: Einstein's big idea (Theory of Relativity)

May 2, 2012 - are you emplying people should refuse to learn and figure things out because people havent been around long? i dont believe in the big bang but science isnt bad either, many different types of science. science is responsible for you driving to work or turning a light on in your house. science is how man goes to space where theres no gravity and still comes back, man has it down to a science so he's able to do so. the momment people stop trying to learn anything is the momment theres no progress

May 8, 2012 - Plus as said by Maxplank that light has a particle nature, it has mass. So according to mechanical physics, the relative velocity of light will be 1/2 when Einstein's bro travel by a speed of 1.5X10^8 m/s. And further if Einstein travells by the speed of light with his flashlights on, he won't see any light passing by him.. So the best way to travel through time is moving around the earth in clockwise direction with a speed of approx. 5000 m/s :P

May 15, 2012 - what if einstein traveled?

May 18, 2012 - I still fail to see how any combination of time or distance dilation would account for a beam of light directed toward the ship to be observed as the "constant" speed of light???

May 22, 2012 - forget time travel... that clock can't be real :O

alasjajo Says:

May 23, 2012 - time is not physical...therefore, can not change

Whiteroca Says:

May 24, 2012 - the clock is fake?

May 24, 2012 - to time travel you need to move at 88mph in a Delorean.

alasjajo Says:

May 25, 2012 - am i wrong?

David Vieyra Says:

May 26, 2012 - ok that explains going forward in time, how would you explain going backward in time, anyone?

aninjalo Says:

May 26, 2012 - Well this theory fails, because it is assuming that time is a strict progression of cause and effect (I.E. the decision of traveling with the light clock, results in the light taking longer to bounce between ticks, thus accelerating time around you). But in actuality, from a non-linear non-subjective point of view, time is more like a big ball of wibbly wobbly timey wimey....stuff

cedownsu123 Says:

May 26, 2012 - In theory, going backward in time would be possible if your system of reference was going faster than the speed of light past everything around you... and if you were going the speed of light, time would stop. Don't worry if you don't get it, this is hard to grasp without visual explanations.

cedownsu123 Says:

May 26, 2012 - To say that, you have to disprove that light doesn't go at an absolute speed in reference to everything.

Manoo62 Says:

May 28, 2012 - What do you think seporates today from yesterday?!?!?! How many physics formula have t for time in them?!?! Pay more attention at school.

Biarry Says:

May 28, 2012 - Then prove time is non-linear "wibbly wobbly stuff" by replying to this comment before i post it.

aninjalo Says:

May 28, 2012 - I would, but there are certain events that are fixed points in time that should not be tampered with, or else there will be a rip in the space time continuum. However, I wrote this comment in the past for both of us to read. By the time you read this in my future, I would have already read this in your past. Therefore, your past is my future. Wibbly Wobbly Timey Wimey :).
