Is it safe to travel through a wormhole?

Physicists have worked out a way that it might be feasible to send someone through a wormhole. Wormholes are tunnels between two black holes that connect distant regions of space-time, and normally it would be impossible to pass something through them, but factoring in an extra dimension might make it possible.

Why would humans not be able to travel through a wormhole?

Some wormholes may be “traversable”, meaning humans may be able to travel through them. For that though, they would need to be sufficiently large and kept open against the force of gravity, which tries to close them. To push spacetime outward in this way would require huge amounts of “negative energy”.

Why can’t you cross a wormhole?

This instability and “non-transversability” occur because of two properties: The Schwarzchild wormhole is time-dependent. The wormhole opens and closes too fast for travelers to cross them. Tidal forces at the throat of the wormhole are too strong, killing the traveler.

What is the shape function of a wormhole?

Equation 13: Line element of a wormhole with the necessary properties described in the text. The so-called shape function b ( r) determines the spatial shape of the wormhole. The circumference of the throat is given by 2π r. The function Φ is called the redshift function.

When was the first wormhole discovered?

Figure 1: A wormhole in two dimensions. The first type of wormhole was discovered by the Austrian physicist Ludwig Flamm. The discovery was published in his 1916 paper “ Comments on Einstein’s Theory of Gravity ” (see figure below).

What is the tension in the throat of a wormhole?

Using Einstein field equations one can calculate the tension in the throat of the wormhole. If the radius of the throat is 3 km, the tension in the throat is equal to the pressure in the center of the most massive neutron star!
