The black holes are not evil.
They are incredibly powerful places. The objects are so dense that not even light can reach them. For the first time, scientists have published evidence that a black hole is moving fast.
A black hole is created when a star explodes and collapses into a small object. The evolution of our universe is natural.
These are not planets. Kailash Sahu, an astronomer at the Space Telescope Science Institute who led one of the studies about this detection, said that wandering stars become black holes.
Around 100 million black holes are travelling through the universe. It's a good idea. The stars are no longer alive. There are lots of stars around. On the other hand, our universe has 100 billion stars. The collapse of stars is a common way of forming black holes.
The astronomer who had no role in the new research agreed that the universe should be filled with black holes.
"The Milky Way should be full of black holes."
It is possible that there are many black holes in our galaxy, but they are not close to our solar system. One light-year is nearly 6 trillion miles. The closest rogue black hole should be 80 light-years away. The closest star to us is four light years away.
It's important to remember that we are as well. Our solar system is moving around the center of the Milky Way at over half a million miles per hour.
Sahu said that everything is wandering.
After being created during catastrophic explosions, the rogue black holes have been given a good kick that leads them on a more random path through the universe. If a black hole were to pass close by, it could cause problems for the planets. Everything in the universe is not being sucked up by black holes. Douglas Gobeille, an astronomer and black hole researcher at the University of Rhode Island, told Mashable that they are not vacuum cleaners.
There are black holes that do not emit light. Calculating how to see the unseeable is a challenge.
The astronomer made this observation over several years. It's like a bowling ball sitting on a mattress. The research team used the school bus-sized Hubble Space Telescope to watch for an extremely dense object to pass in front of a distant star. Microlensing is a type of observation in which the starlight is bent by the black hole's presence.
The Hubble telescope had to observe minute changes in light in order to measure how much light the black hole was emitting. Hubble is an instrument that makes this observation because it's above Earth, so it's not affected by our atmosphere.

Astronomers were able to see the black hole's mass, distance, and beyond with the help of the observations. The black hole is almost like a scale. The black hole is seven times larger than the sun. 30 percent of wandering black holes are thought to travel alone.
According to the astrophysicist, this is a very remarkable discovery.
"This is a very remarkable detection."
There is still one unresolved issue. There is a chance that what has been detected is a dense object that can cause space to warp. A sugar cube-sized amount of material would weigh about the same as Mount Everest. NASA gives an explanation. The object was 1.6 and 4.2 times the mass of the sun. If an object is 1.6 times the size of the sun, it's a neutron star.
There is one more piece of evidence that supports the idea that the object is a black hole. The object didn't change the light color of the star. The light sources would have been 888-609- 888-609- 888-609- There was no change.
Black holes are moving at 100,000 mph. In the future, advanced space telescopes like NASA's Roman Space Telescope will be able to spot many more of these curiosities.
