A few things about black holes and white holes you may want to know as an astronomy enthusiast!

I'm sure we've all heard about black holes, a cosmic object usually formed by the death of a star. It cannot be seen through telescopes as it doesn't emit nor reflect light. The first black hole wasn't discovered until scientists had used X-ray Astronomy.

There are millions of black holes in our galaxy. As interesting as they seem, anything that gets too close will be pulled with an immensely strong force and be immediately crushed. Inside a black hole, the gravity is too strong for anything to escape. They are believed to turn anyone who goes in there into spaghetti. Although it may sound ridiculous, the process is known as "spaghettification" where any form of matter is pulled into a thin wire. It is believed that the pain depends on the size of these bottomless pits. Once entered, there is no surviving. 

Although black holes have been proven real, white holes are still considered a theory which isn't believed by many scientists. They are known to be celestial objects expanding outwards from a space. Unlike black holes, they would repel matter. A white hole would emit light and energy, proving them to be the opposite of a black hole.

Black holes and White holes both have an event horizon. In the black hole, it is a boundary where the velocity needed for one to escape it exceeds the speed of light. No particle can escape the boundary once it passes through and it'll be torn apart into its smallest subatomic components be forced into the singularity. 

The white hole's event horizon, however, would eject matter into the universe. No particle can enter this boundary, and although the white hole may seem safer, the intensity of the repelling force would be strong enough to make a spaceship explode into gamma rays (the smallest wavelengths). 

In conclusion, if white holes were ever proven to exist, they would be as equally destructive as black holes.

A few facts:
1) Black holes ARE NOT holes.
2) Black holes aren't black, they are the brightest objects so far found in the universe.  
3) Every galaxy has a SUPER MASSIVE black hole.
4) The first Black hole we ever captured, Sg* (Sagittarius A-Star) was of another galaxy!
