UFOs And Stopped Clocks

[Karl12]

Why place the warping of space-time out there with black holes when gravity is right under our feet?

It all gets a bit too technical for me after a certain point mate but did enjoy listening to this physicist who reckons time 'doesn't exist' - this other Professor also states there are objects outside our spacetime.

I don't pretend to have any idea what's going on but some of the ideas out there are truly fascinating so thanks for the link - apparently even Stephen Hawking had to do a U turn and admit time travel was 'possible'.

The embarrassing thing, however, was that no matter how hard physicists tried, they could not find a law to prevent time travel. Apparently, time travel seems to be consistent with the known laws of physics. Unable to find any physical law that makes time travel impossible, Hawking recently changed his mind. He made headlines when he said, 'Time travel may be possible, but it is not practical..'
