Time Travel Options

[Mommy]

I have been hearing A LOT of talk lately that this is possible. I don't really understand how it could be. What do you all think and give an explanation as to why you think that way.

I feel this is an NPR issue because science is news.

I seem to recall a discovery channel show where they showed this test of two synchronized clocks, then put one in a blackbird and let it fly mach 5 or whatever it does and when it got back the clocks were off by some tiny fraction of a second.

yes this did occur. They used atomic clocks.

You can't ever travel "back" in time. But it is possible to slow time down relative to others. But like impala said, it requires a great deal of speed relative to others.

and energy...
