OK, Take me back 40 years. Then take me forward 80 years

if there is no motion, does time exist?

I read this article before I decided not to open it.

George Allen: "The future is now."

So does this open a door to faster-than-light travel?

[bobdsmith]

Maybe this brings modern science one step closer to understanding how the act of flying round the earth very fast results in travel backwards in time. But im not holding my breath - if superman wanted us to understand time travel he would have surely told us himself.

Chuck Norris once kicked a man so hard that his foot broke the speed of light, went back in time and killed Amelia Earhart flying over the Pacific Ocean.

Whbat can possibly have led this physicist to guess that time is geometrical at all?

[muawiyah]

Just collectibles ~ that's all I need to know about.

Imagine that 'the arrow of time' in the Universe, like gravity on Earth, is pretty much the same everywhere, yet also different everywhere relative to everywhere else. That means that the 'arrow of time' points in different directions in spacetime depending on where you are, so time has a geometry just like space has a geometry.

A natural progression of relativity?

[InterceptPoint]

I am such a sucker for this stuff. I will buy this guy's book sight unseen.

[Hootowl]

Ah, yes, time flies like an arrow. On the other hand, fruit flies like a banana.

[capitalist229]

What does this have to do with the eleven dimensions (and parallel universes) needed to unite gravity and quantum physics into a single theory ?

Have they observed enough high energy neutrinos yet to prove it ?

ping!

I keep running out of time

[MarkL]

Time is nature's way of making sure everything doesn't happen at once!

Time flies like an arrow, but fruit flies like a banana.

[techcor]

Time = delta t = change. Which is why it is silly to say that because something goes faster than light that it would go back in time. Time is propagated by whatever the fastest medium that there is to propagate change.

[Billthedrill]

Dunno - I've become a believer in the Second Law of Thermodynamics and in the one-way nature of time ever since my butt started to sag toward Australia. If it snaps back I'll let the theoretical physicists know. Ain't holdin' my breath.
