Can black holes create stars?
Research combining systematic observations with cosmological simulations has found that, surprisingly, black holes can help certain galaxies form new stars. As they blast energy into their host galaxy, they heat up and eject that galaxy’s gas, making it more difficult for the galaxy to produce new stars.
Which type of star would likely eventually form a black hole?
In general, stars with final masses in the range 2 to 3 solar masses are believed to ultimately collapse to a black hole.
Does a black hole have more mass than a star?
For decades, astronomers have been puzzled by a gap in mass that lies between neutron stars and black holes: the heaviest known neutron star is no more than 2.5 times the mass of our sun, or 2.5 solar masses, and the lightest known black hole is about 5 solar masses.
Is there a universe in every black hole?
The birth of our universe may have come from a black hole. Most experts agree that the universe started as an infinitely hot and dense point called a singularity. It is, in fact, and some physicists say they could be one and the same: The singularity in every black hole might give birth to a baby universe.
How are black holes formed in the Solar System?
A stellar-mass black hole, with a mass of tens of times the mass of the Sun, can likely form in seconds, after the collapse of a massive star. These relatively small black holes can also be made through the merger of two dense stellar remnants called neutron stars.
How big is the mass of a black hole?
By knowing the speed of the gas, the mass of the black hole can be calculated. A black hole in the center of a galaxy in the constellation Virgo is believed to have a mass equal to that of 3 billion Suns! An even better way of studying black holes is through the use of X-ray observations.
Can a black hole be formed from a dying star?
Black holes with masses between about 50 and 120 suns cannot be formed, at least from a dying star, so the story and the calculations go. In stars massive enough to make such a beastly hole, the interior grows so hot when collapsing that light spontaneously creates pairs of electrons and positrons.
Is there danger of Earth being pulled into black hole?
Since this black hole already weighs a few million times the mass of the Sun, there will only be small increases in its mass if it swallows a few more Sun-like stars. There is no danger of the Earth (located 26,000 light years away from the Milky Way’s black hole) being pulled in.
