Cosmic Shortcuts: Traveling in Time with Wormholes
<p><strong><em>What about the speed of light? </em></strong>Our nearest star is Proxima Centauri, just over four light-years away. Now, with a wormhole, if we can connect a point in space just outside the Earth’s atmosphere to a point near Proxima Centauri, you can basically fly a spaceship and instantly appear in the other star system and see if there are any habitable planets there. Unfortunately, i believe that this will not happen in the next few years. If there are habitable planets there, see if there is life there. It was predicted for almost 60 years. The people who came up with this idea were Einstein and a man named Rosen. Actually, it’s a wormhole. This is called the Einstein-Rosen bridge. So it’s been known for a very long time, but the practicality of actually making one is incredibly difficult. You might need something called exotic matter, and that’s actually a matter that has negative mass. Imagine that space is like a big rubber sheet and can be deformed.</p>
