What is the Einstein Rosen bridge theory?

In 1935, Einstein and physicist Nathan Rosen used the theory of general relativity to elaborate on the idea, proposing the existence of "bridges" through space-time. These bridges connect two different points in space-time, theoretically creating a shortcut that could reduce travel time and distance.

Do wormholes in space exist?

Wormholes (opens in new tab) — shortcuts in space and time — have long been a staple of science fiction. But some scientists believe we may soon be able to prove that they are a real part of the universe—as real as the sun and the stars or you and I. Where do scientists think wormholes exist? Physicists believe wormholes may have formed in the early universe from a foam of quantum particles popping in and out of existence. Some of these “primordial wormholes” may still be around today.

Why are wormholes called wormholes?

(Black holes, of course, allow matter and energy to enter but, much like the Hotel California, once you enter, you can never leave.) Since the name “Einstein-Rosen bridges” is a bit dry, they became more commonly known as wormholes. You can picture a wormhole as a kind of tunnel that connects two points in spacetime. Can humans survive a wormhole? Humans could survive a trip through a wormhole, but there's a catch. There are drawbacks to this method — namely, such wormholes would be only microscopic, which means even the most hardcore exercise routine wouldn't make humans thin enough for the trip.

How many dimensions do we live in?

Secret dimensions

In everyday life, we inhabit a space of three dimensions – a vast 'cupboard' with height, width and depth, well known for centuries. Less obviously, we can consider time as an additional, fourth dimension, as Einstein famously revealed. What is a white hole in space? White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.

How many dimensions are there?

The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. Can time be defined? Physicists define time as the progression of events from the past to the present into the future. Basically, if a system is unchanging, it is timeless. Time can be considered to be the fourth dimension of reality, used to describe events in three-dimensional space.

Is time Travelling possible?

In Summary: Yes, time travel is indeed a real thing. But it's not quite what you've probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second.
