What does the crack of the universe look like?

The universe may exist "cracks", as a result of the Big Bang.

Cracks in spacetime may exist, but human telescopes cannot see them. These may be remnants of the time immediately after the Big Bang, when the cosmic temperature dropped rapidly.

That cooling process, known by scientists as the "transition period , " can be thought of as bubbles with low temperatures bulging everywhere, and they encounter other bubbles to merge. . Eventually, the whole universe became cooler than before.

That transition period may leave cracks at the boundary of the cooling zones. Some physicists call this "cosmic fiber , " which is based on cosmic radiation (CMB) , but current telescopes cannot see them yet.

"Have you ever walked on a frozen lake? Have you seen cracks deep below the surface? The lake is very hard, but there are still cracks underneath," said physicist Oscar Hernandez. explains McGill University, Canada.

"The rock is the water that has gone through a transition. Water molecules once moved freely when in liquid form, then suddenly formed hexagonal crystals when frozen. Now imagine that there is a series of hexagonal crystals fit snugly at one end, and at the other end water crystals also began to form. It is almost unlikely that they will fit into crystals at the top of the lake, " Mr. Hernandez added. theory to explain the cosmic crack.

In a large lake surface, the areas of interference between the water crystals form cracks. In the universe, spacetime cracks form cosmic strands. The search for cosmic fibers can help confirm that the current physical models need further improvement to be able to explain the laws of the universe.

"A lot of models are developed from standard models, with theories like super filaments, which lead to cosmic fibers. It can be said that cosmic fiber is an entity that many models predict real, so if they really don't exist then all models are wrong, "explained Hernandez.

Previously, scientists mainly used the method of collecting data from CMB, then simulating through neural network model. However, in a recently published scientific paper, Hernandez and his colleagues think that observing the CMB will not be able to bring enough clean data to neural networks to detect the cosmic fiber.

Another method being considered is to measure the expansion of the universe in all directions . Although these observatories have not yet been completed, this may be the best way to confirm real-world cracks.
