How do wormholes bend space?

How do wormholes bend space?

In principle, building a wormhole is pretty straightforward. According to Einstein’s Theory of General Relativity, mass and energy warp the fabric of space-time. And a certain special configuration of matter and energy allows the formation of a tunnel, a shortcut between two otherwise distant portions of the universe.

How would a wormhole work?

Wormholes connect two points in spacetime, which means that they would in principle allow travel in time, as well as in space. However, according to general relativity, it would not be possible to use a wormhole to travel back to a time earlier than when the wormhole was first converted into a time “machine”.

How do you close a wormhole?

To safely collapse a wormhole you want to jump through the hole with a very small mass and return with a very large mass. By entering a wormhole with the smallest mass possible you are taking much less risk of the wormhole collapsing behind you, which would trap you on the wrong side.

What is the equation for a wormhole?

But a Stanford theoretical physicist has just come up with a new equation that suggests the key to finally connecting the two could be found in bizarre spacetime tunnels called wormholes. The equation is deceptively simple: ER = EPR.

What do you need to make a wormhole?

All you need are a couple of black holes and a few infinitely long cosmic strings. Easy-peasy. In principle, building a wormhole is pretty straightforward. According to Einstein’s Theory of General Relativity, mass and energy warp the fabric of space-time.

How is a wormhole formed according to Einstein?

In principle, building a wormhole is pretty straightforward. According to Einstein’s Theory of General Relativity, mass and energy warp the fabric of space-time. And a certain special configuration of matter and energy allows the formation of a tunnel, a shortcut between two otherwise distant portions of the universe.

Why does the wormhole keep getting smaller and smaller?

It’s not a perfect solution: Eventually the inherent vibrations in the cosmic strings — the same ones that might keep the wormhole open — pull energy, and therefore mass, away from the string, making it smaller and smaller.

Why are wormholes more unstable than the speed of light?

There’s a small technical difficulty, though: Wormholes, which are bends in space-time so extreme that a shortcut tunnel forms, are catastrophically unstable. As in, as soon as you send a single photon down the hole, it collapses faster than the speed of light.
