Sure, the idea of traveling through black holes has occurred to your mind a few times, but is it possible? Here’s what this expert thinks.
She was mocked at first
In the beginning, black holes were mocked and considered to be purely theoretical fiction in the field of physics.
However, black holes quickly became the focus of science, and excited the audience as well, as soon as observations and astronomical measurements began to reveal their existence, and their importance for all structures in our universe, according to what was stated by Assistant Professor of Physics at Grenell College in the United States, Liu. Rodriguez, in an interview with CNN in Arabic.
Many types of black holes exist, and they can be charged and decay, while some include elements of cosmic expansion and contraction.
However, when looking at the night sky, we will often be able to see one type, i.e. spinning black holes.
Holes turn into “spaghetti”
The universe is governed by specific laws related to conservation of energy, mass, and momentum, which “significantly restrict the ability to travel safely through a black hole,” said Rodriguez, who mainly focuses on studying black holes.
Near the black hole horizon, the side that poses the greatest challenge will be the differential tidal forces.
“Small black holes, or stellar black holes, will have enormous tidal forces,” Rodriguez said.
This means that a person who falls into a black hole with their feet first will experience a dramatically large difference in gravity between the black hole and their head, compared to their feet.
“This could cause a person to stretch out into the shape of long noodles,” Rodriguez said, referring to what is known as the “spaghettification”.
Besides, most black holes are close to stars, and other materials, and this means that they feed on these materials, and the accumulated material may form a very hot cumulative disk.
The area around the black hole is very volatile, and it is likely not suitable for human presence.
Can we communicate with someone who has traveled through a black hole?
And even if someone did manage to travel through a black hole, we probably wouldn’t know that.
A black hole is defined as a region of “space-time” (space-time) in which the force of gravity becomes so great that light cannot escape from it.
And when we consider that all our means of remote astronomical communication rely on some form of light (mostly radio waves), our ability to communicate with anyone beyond the horizon of a black hole would be pointless.
In order for a person to survive traveling through a black hole, we will need a fully formulated theory of how to fully incorporate gravity on the quantum scale, Rodriguez said, and that will require humans to comprehensively understand quantum gravity.
Alongside this, we will also need to identify a black hole large enough to allow mitigation of the tidal forces near the horizon, and in a way that we can be isolated from the accumulating matter.
