stars that are more than four times the mass of our sun reach the end of their life and have burned up all of their fuel, they collapse under the pressure of their own weight. This implosion creates
Astronomer Carl Sagan had it right when he said that time is "resistant to simple definition." Lots of us think we know what time is, but it is hard to define. You can not literally see or touch time, but you can see its effects. The evidence that we...
Wormholes, also called Einstein-Rosen Bridges, are considered to have the most potential for time travel if they do exist. Not only could they allow us to travel through time, they could allow us to travel many light-years from Earth in only a fraction of the...

Yet another theory for how we might travel back and forth through time uses the idea of

J. Richard Gott in 1991.
These are -- as their name suggests -- string-like objects that some scientists believe were...
When wormholes are created, it allows us to travel to the past as well as the future. Here's how it works: Let's say the mouth of the wormhole is portable. Then person B in the example above, who traveled at 50 percent of light speed into space for a few hours, could...
