There is no way a black hole would eat an entire galaxy. The gravitational reach of supermassive black holes contained in the middle of galaxies is large, but not nearly large enough for eating the whole galaxy.
Can a galaxy be destroyed?
Galaxies begin to ‘die’ when star formation stops inside them or they start losing material that forms stars. The ID2299 galaxy is currently ejecting material worth about 10,000 suns every year in the form of cold gas ejection.
Can a black hole destroy the solar system?
A stellar black hole would hurl more comets and asteroids into the inner Solar System, where they could strike the planets. Earth might take some hits, too. But that would be just a warm-up. As the black hole made its way through the Solar System, it would disrupt the orbits of all the planets in it.
How does a black hole affect a galaxy?
The growth of these black holes releases vast amounts of energy that powers quasars and other weaker active galactic nuclei. A tiny fraction of this energy, if absorbed by the host galaxy, could halt star formation by heating and ejecting ambient gas.
Do black holes cause galaxies?
Astronomers believe that supermassive black holes lie at the center of virtually all large galaxies, even our own Milky Way.
What happens if galaxies collide?
What Happens When Galaxies Collide? The merging of galaxies will radically affect their shape. For example, two spiral galaxies can merge and form an elliptical galaxy. Sometimes even more than two galaxies can collide with each other.
What can destroy galaxies?
Black holes might kill entire galaxies with blazing energy,dooming embryonic stars before they can get born and condemning the remainingstars to a slow death, scientists have found.
Can Sun be a black hole?
No. Stars like the Sun just aren’t massive enough to become black holes. Instead, in several billion years, the Sun will cast off its outer layers, and its core will form a white dwarf – a dense ball of carbon and oxygen that no longer produces nuclear energy, but that shines because it is very hot.
What can destroy a black hole?
The only known ways to “destroy” a black hole is to:
- have it merge with another one which turns 2 black holes into 1 black hole, so it is not really “destroyed”
- or wait up to for the black hole to evaporate all by itself through Hawking radiation. (See What would we see if we could watch as the universe is dying?
What would happen if the Sun exploded?
The Sun will get hotter and brighter, and it will start to expand. During this process, it will lose its outer layers to the cosmos, leading to the creation of other stars and planets in the same way that the violent burst of the Big Bang created Earth.
Are wormholes real?
Wormholes — shortcuts in space and time — have long been a staple of science fiction. But some scientists believe we may soon be able to prove that they are a real part of the universe—as real as the sun and the stars or you and I.
What is a white black hole?
White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.
What is the closest black hole to Earth?
1000 light-years
The European Southern Observatory (ESO) astronomers back in 2020 discovered the closest black hole to Earth, which was reported to be just 1000 light-years away in the HR 6819 system.
What is behind a black hole?
At the center of a black hole, it is often postulated there is something called a gravitational singularity, or singularity. This is where gravity and density are infinite and space-time extends into infinity. Just what the physics is like at this point in the black hole no one can say for sure.
Do all galaxies rotate around a black hole?
Everything in the galaxy orbits the center of mass of the galaxy. The supermassive black hole just happens to be at the center. If the black hole at the center were removed, the galactic orbits of almost all objects in the galaxy would not change (except for the few stars that are very close to the black hole).
How black hole is formed?
How Do Black Holes Form? Primordial black holes are thought to have formed in the early universe, soon after the big bang. Stellar black holes form when the center of a very massive star collapses in upon itself. This collapse also causes a supernova, or an exploding star, that blasts part of the star into space.
Can the earth survive Andromeda collision?
Excluding planetary engineering, by the time the two galaxies collide, the surface of the Earth will have already become far too hot for liquid water to exist, ending all terrestrial life; that is currently estimated to occur in about 3.75 billion years due to gradually increasing luminosity of the Sun (it will have
What galaxy is 500 million light years away?
The Cartwheel Galaxy
The Cartwheel Galaxy (also known as ESO 350-40 or PGC 2248) is a lenticular galaxy and ring galaxy about 500 million light-years away in the constellation Sculptor.

Has the Milky Way ever collided with another galaxy?
Milky Way and Andromeda merger has begun
And even though the two galaxies are still 2.5 million light-years apart, the eventual merger of our two galaxies has, in fact, already begun. View larger.
Can a supernova destroy a galaxy?
Supernovas are created during the last moments of a star’s life. These gigantic explosions can wipe out galaxies and the planets inside them.
How do you destroy a galaxy?
The only way the Earth could be destroyed during the slow-motion collision between the Milky Way and Andromeda galaxies would be if it were to collide either with a massive body (planet or a large moon) in orbit around a star, or fall into a star itself.
