Wormholes space spaghetti vacuum donuts alternative theories of time travel

(ORDO NEWS) — The theory of relativity with regards to time is very specific. She says that clocks closer to the center of a large gravitational mass (such as the Earth) run slower than clocks farther away.

They simply do not start the next day until they click through those 38 microseconds that they are behind during the current day. But there are other interesting theories. Although they are a little further than science, they are also worth knowing about.

Can molehills take us back in time

NASA agrees that general relativity provides theoretical scenarios for traveling into the past. But this is not a piece of cake that you can just take off the table. Such a piece is rather wormholes (or molehills).

In general, the topic of molehills is rather speculative. Science fiction has taken this idea and exploits it to the fullest. But – in real life, no one has ever discovered any wormholes of any kind.

So far, everything in this area is purely hypothetical.

An example is an article by the physicist Pascal Coiran (very fresh, October 2021), who, thanks to the new Eddington-Finkelstein metric, traced the movement of a particle through a hypothetical wormhole.

We will not delve into the explanation – just because of the hypothetical nature, but if this topic is interesting, Koiran’s article is still worth attention.

Other Interesting Alternative Time Travel Theories

Other solutions that may allow jumping forward and backward in time are even further from science. Yes, and they have a very significant drawback: a person will not be able to survive under the influence of gravitational attraction and repulsion, which each alternative solution requires. But why not find out about them?

Infinite Cylinder Theory

Astronomer Frank Tipler proposed this mechanism (“Tipler cylinder”):

Obviously, this theory cannot be tested in practice. Yes, even the theory says that this cylinder must either be infinitely long, or made of some matter unknown to people.

So in the foreseeable future, we will not see endless interstellar pasta.

Vacuum donut theory

Theoretical physicist Amos Ory from Israel proposed a model of a time machine created from a curved space-time – a donut-shaped vacuum surrounded by a sphere of normal matter. Here is how the author explained his theory:

If we created a space with a similar curvature that would allow the timelines to close, this could in turn allow future generations to go back in time to visit us.

Of course, there are a few reservations about Ori’s time machine.
