What are some of the dangers in the universe?

Answer 1

The most dangerous thing in the universe is probably the black hole. Black holes are the ultimate cosmic enemy. They're the space regions that the gravity is too strong that things are very difficult to resist or escape their gravity, and even lights can get consumed by the black hole's gravity. Black holes are formed by the death of a very huge star or a dusty matter implosion at the galactic center. If you get too close to a black hole, it's terrible and you'll get killed into a singularity in no time. Fires can be very hot and scary, but waters can defeat the fire by extinguishing them. If the fires ran out of fuel, then it'll disappear. Unlike fires, nothing can defeat a black hole. Black holes are like the humans on earth. We'll try to compare them.

Humans are the most dangerous animals on earth because they damage the environment and threatens the animals. They destroy habitats like deforestation, hunting them down, or sometimes even poaching them, which threatens the animals, therefore animals are going extinct. Animal can't easily attack and defeat people because if they're ready to attack someone, that person will usually kill that animal. If an animal already attacked someone, someone else will usually try to kill that animal. If an animal tried to attack someone, they'll probably get themselves killed. Some carnivorous animals like lions, tigers, leopards, etc. can sounds scary, but animals should be scared of humans instead. Humans are the biggest animal threat, therefore animals can't defeat humans.

This is similar to the black hole theory. Black holes are so strong that nothing can defeat them. Trying to defeat a black hole will get themselves killed. Throwing a fireball or explosive stuffs also won't work because the black hole's gravity will also rip these stuffs. Nothing can destroy black holes and if they try to do, the black hole will probably retaliate.

The only way that black holes can die is through Hawking Radiation. Hawking Radiation is a very slow evaporation of the black hole and it's named after the English theoretical physicist, Stephen Hawking. You can't really see the black holes evaporating, but it's really happening. This is just an incredibly slow process. Nothing can defeat a black hole, and the Hawking Radiation naturally happens. The blacks holes will gradually shed out their surface, slowly evaporate, and gradually shrink down. As the black hole shrinks, then the evaporation gradually accelerates.

This process is incredibly slow, and it would take about a googol years for black holes, especially supermassive black holes to evaporate. During the solar death in billions of years later, you still won't see a big difference. During the degenerate era, you'll see quite a huge difference. The stellar black holes will die first, but the supermassive black holes will last longer like until a googol years. When the black holes already completely evaporated, it'll implode into a singularity and will radiate away in a huge explosion, and that's how blacks hole die.

Black holes takes a very short time to form but a very long time to dissipate and disappear. Black holes takes a much longer time to disappear than to form.

To answer the question, black holes are probably the most dangerous things in the universe.

Answer 2

There's Alot of dangers in the universe.

Our galaxy is on a collision course with another galaxy.

Our magnetic field is becoming weak and will soon be vulnerable to solar flares.

Black holes.

Asteroids.

In a billion years our sun will expand and devour Mercury and Venus. Earth will be too hot for life everything would evaporate or burn. Eventually the sun is gonna blow up and form into a black hole....or a white dwarf. A white dwarf is the end of every sun. There's Allot more dangers... But there's too many to say...hope it helped.

Answer 3

If by most dangerous you mean "What can destroy the Universe" there is only one active agent with this potential - entropy. This is the gradual depletion of energy in system that eventually results in low level residual energy that is useful for no reactions .
