Most likely not. The best evidence of the existence
of black holes has been found deep within galaxies.
Black Holes.
Answer
No. There are no black holes in our solar system. Based on current models, the smallest stellar mass black holes are at the very least about 3 times the mass of the sun. Therefore, if there were a black hole in our solar system the sun would either orbit it or the two would orbit about a common center of mass.
Even though black holes suck through parts of the universe, the universe is inevitably big, and growing so as the universe is being sucked into another dimension by black holes, it is also expanding.
There are already black holes within the universe
Black Holes' can 'eat' any type of matter in the Universe.
Probably stellar mass black holes
The universe likely contains millions upon millions of black holes.
No.
Yes.
The black holes may not devour everything since the outward velocity of the matter in the universe may escapethe gravitational pull of the black holes. Stephen Hawkins reckons that even the mass in the black holes would diminish over time, though over trillions and trillions of years.
Primordial black holes are theoretical black holes that could have formed in the early universe. They are thought to be small and have a wide range of masses. If they exist, they could have implications for dark matter, gravitational waves, and the evolution of the universe.
