What is a Worm Hole. Could Wormholes Allow Time Travel

Space-time can be warped and distorted. It takes an enormous amount of matter or energy to create such distortions, but theoretically, distortions are possible.

In the case of the wormhole, a shortcut is made by warping the fabric of space-time. Imagine folding a piece of paper with two pencil marks drawn on it to represent two points in space-time.

The line between them shows the distance from one point to the other in normal space-time.

If the paper is now bent and folded over almost double – the equivalent to warping space-time –  then poking the pencil through the paper provides a much shorter way of linking the two points, in the same way a wormhole would create a shortcut.

The problem with using wormholes to travel in space or time is that they are inherently unstable.  When a particle enters a wormhole, it also creates fluctuations that cause the structure to collapse in on it.

The latest study suggests there are unusual-shaped wormholes that may be able to stay open longer than normal.

Einstein believed worm holes could open up a window into a different era. The problem with his theory is that, if worm holes exist, they don't stay open long enough for anything to pass through them. But a new study at Cambridge University suggests unusually-shaped wormholes could stay open longer than normal

Could Wormholes Allow TIME TRAVEL

Collapsing ‘tunnels’ could let us receive messages from the future, claims physicist

  • Wormholes are theoretical tunnels that create shortcuts in space-time
  • If a message entered a wormhole, it could reach the future or the past
  • But wormholes are thought to collapse before a message could get out
  • Dr Luke Butcher argues if a wormhole is longer than it is wide, the amount of negative energy inside would allow it to stay open longer than normal
  • Long enough, he claims, to carry a single particle of light through time
  • In theory, this photon could carry a message to a distant past or future

We’ve all wished someone from the future could send us tomorrow’s lottery ticket numbers.

While it may seem wishful thinking, a physicist from Cambridge University believes that, in theory, it could be possible.

He argues that if a thin wormhole stays open long enough, people might send messages instantly through time using pulses of light.

It sounds like the stuff of science fiction, but the theory of wormholes being used to send objects through time was first suggested by Albert Einstein’s calculations.
 

Wormholes are theoretical tunnels through the fabric of space-time that can create shortcuts for long journeys across the universe.

The problem with his theory is that, if wormholes exist, they don’t stay open long enough for a human, or even a single particle of light, to pass through them.

But a new study at Cambridge University suggests that some wormholes are capable of staying open long enough to send messages backwards and forwards through time.

In 1988, physicist Kip Thorne at the California Institute of Technology suggested that wormholes might be kept open through the use of a negative energy, known as Casimir energy.

According to modern physics, the vacuum is full of fluctuating electromagnetic waves of different possible wavelengths which creates a vast amount of energy, normally invisible to humans.

Between two parallel plates in a vacuum, some energy waves would be too large to fit through creating a negative Casimir energy.
