Speed of Light broken?

[Darth Biscuit]

I would like someone to explain to me how they measure such things... not that I would understand it, I would just like to hear it.

I thought I heard a theory that if you were to go around the Earth, opposite it's natural spin, faster than the speed of light, you would eventually start going back in time...

i think that's how superman does it.

meh the aliens are saying been there done that,

Well if that is true then, they also recorded time traveling in the same experiment. ;)

But then again, that not really a big deal bc it's already been proven. (forward not back)

And backwards at a molecular level. Both are theoretically possible.

Time travel both forwards and backwards is possible and already happens.

Forward time travel is not really jumping forward in time. It is YOU traveling through time at a different rate than everyone else because of speed and mass and such. According to Einstein time goes more slowly in higher gravitational fields. This is measurable.

As another poster mentioned actually traveling forward in time would invlove a wormhole or skirting around the edges of a black hole. The practical aspects of this are dizzying. Harnessing enough energy to do this would require hooking up with a star. not to mention what happens to a physical body through this process.

I took a relativity class in college and we spent a week discussing how it might be possible. I barely grasped it but it was interesting and I could see how it would be possible.

Backwards time travel also happens in real life at a molecular level. Something about electrons spitting out protons in the past. I couldn't understand it. This and somehow having time loop back on itself with a wormhole or something.

The paradox of time travel is explained by alternate universes which seems like something completely fictional. Stephen hawking says if backwards time travel were possible wouldn't we have had a visitor from the future by now?

I'm guessing it is nothing more than shooting a particle from A to B and figuring out a way to time it.

OK its probably much more than that but I'm that is what the particle accelerators are built to do.

Yeah I mean the very basic principles of it aren't hard to grasp, but the practicalities of measuring particles that small moving that fast are mind boggling.

Here is a tidbit.

http://www2.slac.stanford.edu/vvc/detectors/cerenkov.html

Outside the drift chamber is the Cerenkov detector, or more accurately, the Cerenkov Ring Imaging Detector (CRID). It is used to measure particle velocities through Cerenkov radiation. This form of radiation is somewhat like a sonic boom except it is light rather than sound. It occurs when a particle travels through a medium (here, freon gas) at a speed that is faster than the speed of light in the medium (but slower than the speed of light in a vacuum, of course), just as a sonic boom occurs when an object travels in a medium (air) faster than the speed of sound in the medium.

They compare it to a Cam Newton pass. If its moving faster, then it must be breaking the speed of light. :)

All underlined I am aware of and I have seen the Stephen Hawking time travel (paradox) shows as well as the Albert Einstein shows or rather shows that explain his findings and theories. I could watch this kind of stuff all day long!

I wasn't aware of the Backwards time travel molecular or otherwise. Good stuff though! :thumbsup:

I'll find a link...

What is this, I don't even.
