What is the extra dimension of the universe?

In physics, extra dimensions are proposed additional space or time dimensions beyond the (3 + 1) typical of observed spacetime, such as the first attempts based on the Kaluza–Klein theory.

How many dimensions were there before the Big Bang?

Our Universe has four dimensions of space-time. If we imagine a fifth dimension existed, then our Universe would appear as a four-dimensional sheet in this five-dimensional space.

Who first proposed extra dimensions of space?

The idea that space–time could have more than four dimensions was first proposed by the German mathematician and physicist Theodor Kaluza and the Swedish theoretical physicist Oskar Klein in the early 20th century.

What is brane theory?

In string theory and related theories such as supergravity theories, a brane is a physical object that generalizes the notion of a point particle to higher dimensions. Branes are dynamical objects which can propagate through spacetime according to the rules of quantum mechanics.

Where did the singularity come from?

The singularity comes from winding the Cosmic clock backwards to the point of the Big Bang. And thus all the mass/energy of the universe can be accounted for in a single atom size point which provides the power for the “bang” when it explodes.

How many dimensions does the universe have?

This would technically agree with a computer model from 2012 where Japanese scientists found that at the moment of the Big Bang, the universe had 10 dimensions, but only three of these spatial dimensions expanded. So, the three-dimensional space we experience could have formed from 10 dimensions, just as superstring theory predicts.

Why can’t we add more dimensions to space?

If you add more dimensions, the process becomes unstable. “Of all possible dimensionalities of space, our mechanism picks out three as the only number of dimensions that can inflate and thus become large,” the team wrote.

Why do we live in three large spatial dimensions?

“Of all possible dimensionalities of space, our mechanism picks out three as the only number of dimensions that can inflate and thus become large,” the team wrote. “This model may explain why we live in three large spatial dimensions, since knotted/linked tubes are topologically unstable in higher-dimensional space-times.”

How did the universe evolve?

The researchers say that when the network broke down, it filled the universe with a gas of subatomic particles and radiation, allowing the evolution of the universe to continue to what we see today.
