Black holes spurred much intrigue in the past years, especially that its gravitational waves have already been discovered. In the event that Earth does fall into a black hole, the planet will become what looks like a spaghetti strand, fried with radiation and a hologram of itself will be made.
All of these are not really good news.
Since black holes have no "hair," scientists won't know from the outside what happens inside, thus the true nature of what goes on inside of it remains a big mystery. Although, from the outside, observers can determine three properties of black holes - mass, spin and electric charge.
Just Like Spaghetti Strands
If ever Earth falls into a black hole, three events are speculated to take place. One of the most popular effects of a black hole is "spaghettification," which means if objects stray too close to a black hole, it will stretch out, just like spaghetti.
This effect is brought about by a gravitational gradient across the object or a body, for instance. If the earth comes too close to a black hole, the nearest part of the planet will be pulled by the tremendous gravitational power, while leaving the farthest part with a slight gravitational pull.
In effect, the object will not only become elongated, but also will thin out or compress in the middle. Any object, or the Earth in this scenario, will resemble a pasta strand, which becomes long even before it reaches the black hole's center.
When the Earth is pulled this way, anything in it will be ripped apart, since humans and other entities on the planet are not elastic.
Holographic Existence
Humans on Earth might not even notice the doom, just yet. This is because everything would appear as it once was, but for only a small period of time. A new theory, however, points out that rather than being totally destroyed, a person or the Earth, for this matter, falling into a black hole would actually be absorbed into a hologram.
The "fuzzball" theory says that a black hole's boundary does not destroy anything it touches. This theory is opposite of the popular "firewalls" theory that claims that any material touching black holes will be destroyed.
The new hypothesis suggests that anything that touches a black hole will become an imperfect copy of itself that will continue to exist as before. The Earth and anything in it might live on holographically.
Radiation-Fried
Black holes can emit huge amounts of radiation whenever it is feasting on new material. When Earth is pulled by the strong gravitational power of a black hole, even before being spaghettified, the power of its radiation will fry the planet and anything in it.
