What Happens If We Fall into a Black Hole?

We do not yet know exactly what is happening in the black holes or exactly what kind of processes are going on. Nevertheless, it is possible to predict what should happen near celestial bodies with high gravitational force, such as black holes, using the Theory of Relativity.

First, the things an astronaut experiences falling into a black hole will be very different from that of someone who watches his fall safely from the outside. The astronaut, too close to the enormous gravitational force of the black hole, will be influenced by a so-called tidal force. So different parts of his body will experience different amounts of gravitational force. For example, the gravitational force in the head of an astronaut plunging into a black hole (head ahead) will be much greater than the gravitational force in its feet. Therefore, it will grow like a spaghetti. This concept, popularized by Stephen Hawking, is called spaghettification.

If the black hole falling into it is a supercluster black hole, the effect of tidal forces is much smaller and more manageable. Because the Gargantua black hole shown in the Interstellar film is such a black hole, the famous scenes are quite accurate.

Regardless of its mass, the most important effect caused by a black hole is the so-called time dilation. An external observer who observes that an astronaut has fallen into the black hole can never see the astronaut fall into the black hole; he sees it as if he is constantly in a fall. Because the sequential nature of the light that comes to our eyes is one of the elements that creates our perception of time and separates one moment from the other. The light coming from a moving object also passes through different space-time zones and reaches our eyes and creates hareket motion perception ".

But we said that even light could not escape the gravitational force of the black hole. In this case, an observer watching an astronaut reaching the event horizon will see that the astronaut freezes in the event horizon. Because the photons carrying motion information can never reach the eye.

Is it possible to escape from black holes?

Since we don't know what's inside a black hole, it's not easy to answer. However, some theorists believe that black holes are actually part of a space-time tunnel called a wormhole. Wormholes can be thought of as space-time tunnels connecting different parts of the Universe. These tunnels are thought to have black holes (objects that swallow everything) at one end and white holes (objects that vomit everything) at the other end. You can read our article about white holes here.

But unlike black holes, the existence of wormholes has not yet been fully demonstrated, even theoretically. In fact, physicists who first proposed the idea showed that the energy required to keep a wormhole stably "open" was extremely large. Therefore, this idea remains as a speculative thought.
