Five-dimensional regular black holes in a brane world (2024)

FAQs

Is there 5 dimensions in black hole? ›

A black hole is actually a four-dimensional object. A black hole extends across all four physical dimensions of the universe. The four dimensions that form the background framework of the universe consist of three spatial dimensions and one time dimension.

For instance, four-dimensional black holes are known to have a number of remarkable features, such as uniqueness, spherical topology, dynamical stability, and to satisfy a set of simple laws — the laws of black hole mechanics.

There is a long history to the idea that black holes may connect with other regions of the Universe, or other universes entirely, but this is purely speculation.

Cosmic Core

Astronomers have evidence that some galaxies orbit supermassive black holes at their cores. By tracking the movements of stars near the center of the Milky Way galaxy, scientists found that the stars orbit a massive invisible object—most likely a black hole about two million times the mass of the Sun.

The 5th dimension can't be observed, but its influence might be visible. Since the 5th dimension is so small, it's unobservable on any scale less energetic than the state of the universe at the Big Bang (particle accelerators can get close to this energy level, but can't match it).

The fifth dimension is a micro-dimension which is accepted in physics and mathematics. It's here to have a nice and seamless tie between gravity and electromagnetism, or the main fundamental forces, which seem unrelated in the regular four-dimensional spacetime.

We live in a world of three dimensions.

We move through space , either left or right, forward or backward, up or down. Everything around us, from the houses we live in to the objects we use in everyday life, has three dimensions: height, length, and width.

According to Einstein , you need to describe where you are not only in three-dimensional space* — length, width and height — but also in time. Time is the fourth dimension. - - unquote. According to the science we know, yes, we live in the fourth.

White holes are the opposite of black holes, in that they spit out light and matter, rather than trapping it. So far, white holes are purely hypothetical objects, but astronomers are contemplating how they could form in reality.

When matter falls into or comes closer than the event horizon of a black hole, it becomes isolated from the rest of space-time. It can never leave that region. For all practical purposes the matter has disappeared from the universe.

Where would a black hole take you? ›

By their calculations, quantum mechanics could feasibly turn the event horizon into a giant wall of fire and anything coming into contact would burn in an instant. In that sense, black holes lead nowhere because nothing could ever get inside.

Since nothing can escape from the gravitational force of a black hole, it was long thought that black holes are impossible to destroy. But we now know that black holes actually evaporate, slowly returning their energy to the Universe.

Black holes seem to be the stuff of science fiction (and, in fact, have starred in many sci-fi books and movies), so it's not uncommon for people to wonder, are black holes real? As it turns out, the answer is yes, though for a long time most scientists were convinced that black holes were purely theoretical objects.

No, black holes are not portals to another dimension. If you cross the event horizon of a black hole, your are doomed to follow a trajectory to the singularity at the center.

This still from a computer simulation depicts the shape of a theorized five-dimensional black hole, which appears as a ring instead of a sphere. In the simulation, the black-hole ring starts off smooth, but then gives rise to a series of strange bulges. (

Many scientists postulate that wormholes are merely projections of a fourth spatial dimension, analogous to how a two-dimensional (2D) being could experience only part of a three-dimensional (3D) object.

Polytopes. In five or more dimensions, only three regular polytopes exist. In five dimensions, they are: The 5-simplex of the simplex family, {3,3,3,3}, with 6 vertices, 15 edges, 20 faces (each an equilateral triangle), 15 cells (each a regular tetrahedron), and 6 hypercells (each a 5-cell).

The fourth dimension (4D) is currently defined as a hypothetical construct since we live in the third dimension and must predict what the extra-spatial fourth dimension actually consists of. But generally, the 4D space is seen as an extension of the 3D space, providing further ways that objects can move.
