How are Black Holes formed?
Primordial black holes are thought to have formed in the early days of the universe, shortly after the big bang. Stellar black holes or star black holes formed due to a very massive star collapsing on its self. The collapse doesn't always result in a black hole. The collapse could be a supernova, or an exploding star, that spreads apart other stars.
What is a Black Hole?
A black hole is a massive ball of death. A black hole is so strong that particles and light can't even escape from it. Because light can't emit light, no one can see a black hole; it's completely invisible. Unless you have a special tool, like the event horizon telescope. The event horizon would basically create a shadow around the black hole. The shadow would be withered by light from hot gas outside the invisible ball of destruction. This process allowed us to see a black hole for the first time in history.
Do Black Holes Die?
Yes, everyone & everything dies? Basically, there are tiny particles called space & these particles collide with each other. But once they get too close to the event horizon, one partial will escape & the black hole will eat one. This causes the black hole to lose energy, which over time, it becomes faster & faster. Once the black hole's life is coming to an end, it will radiate away with the energy of billions of nuclear bombs.
What is the Event Horizon of a Black Hole?
The Event horizon is the boundary marking the limits of a black. At the event horizon, the escape speed is equal to light speed (186,000 mph). In simple terms: the point of no return.
Will a Black Hole Ever Destroy Earth?
I don't know about you, but I won't be alive for billions of years. A black hole will not destroy the earth. Let's pretend, what if the Sun became a black hole the same size as the sun. What would happen to Earth? Well, nothing would change other than us freezing to death. Not to mention, our Sun will kill Earth. Our sun uses Hydrogen & Helium as its fuel. But the problem is in 5.5 billion years; the Sun will run out of fuel. When that happens, the Sun will begin to expand. As a result of expansion, the Earth will receive more light & more heat, which will cause water to evaporate, which would result in life on Earth dying. Then finally, Earth will become a burning planet. Then eventually, the Sun will eat Earth. Finally, billions of years later, the sun will explode & become a white dwarf "fun times."
How was the Black Hole Picture Taken?
The Black Hole or Messier 87 picture was taken with the Event Horizon Telescopes. The Event Horizon Telescope was a series of ground-based radio telescopes. A radio telescope is the main observing instrument used in radio astronomy, which studies the radio frequency.
How many Black Holes are there in the universe
No one really knows. But scientists have predicted that there are probably 10 million to billions of black holes in our galaxy; the milky way. They were able to come up with this number due to the number of large enough stars to produce a black hole.
What happens if 2 black holes collide
When two black holes spiral around each other, that means they are eventually going to collide. When they collide, they send out huge gravitational waves. A gravitational wave is when ripples are created due to some of the violent and energetic processes. These cosmic ripples travel at the speed of light; they carry information with them about their origins.
- Black Holes formed after the big bang.
- Black holes form from the star collapsing in on itself.
- When a black hole dies, it explodes.
- The event horizon is the point of no return.
- A black hole will never destroy Earth. The Earth will die from the Sun. becoming a red giant.
- The Black Hole picture was taken with radio telescopes.
- When black holes collide they send out huge gravitational waves.
- There are 10 million to a billon black holes in our galaxy alone.
