Can a black hole destroy a galaxy?

Is it possible for a black hole to "eat" an entire galaxy? No. 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 black hole eat the galaxy?

A single Black Hole, even one at the center of our Milky Way galaxy, is just too small to eat an entire galaxy.

Can a black hole destroy a star?

The destruction of stars by the gravitational influence of black holes is called a tidal disruption event (TDE). This TDE designated AT2021ehb involved a black hole with a mass 10 million times that of the sun.

What would happen if a black hole entered our galaxy?

However, if a black hole as massive as the Sun entered our Solar System by some other means, things would be quite different. Planets would be slung away into space by gravitational forces, or they would be ripped apart by the strong tidal forces of the black hole.

Can black holes delete the universe?

The overwhelming majority of the Universe will not be consumed by black holes, but rather flung into intergalactic space. Once there, they will wander the Universe as "runaway stars" (or stellar remnants) for as long as the Universe still exists.

What If a White Hole and Black Hole Collided?

Are black holes endless?

Well, even though black holes are extreme in many ways, they don't have infinite mass—and it's mass that determines the force of their gravity.

Does time exist in a black hole?

Near a black hole, the slowing of time is extreme. From the viewpoint of an observer outside the black hole, time stops. For example, an object falling into the hole would appear frozen in time at the edge of the hole.

What if a black hole ate the sun?

Contrary to popular belief, the Solar System would not be sucked in: a solar-mass black hole would exert no more gravitational pull than our Sun. As this computer simulation shows, the planets would actually continue on in their orbits as if nothing had happened.

How to destroy a black hole?

Since nothing can escape from the gravitational force of a black hole, it was long thought that black holes are impossible to destroy. But we now know that black holes actually evaporate, slowly returning their energy to the Universe.

What is the closest black hole to Earth?

Astronomers have discovered the closest black hole to Earth, the first unambiguous detection of a dormant stellar-mass black hole in the Milky Way. Its close proximity to Earth, a mere 1,600 light-years away, offers an intriguing target of study to advance understanding of the evolution of binary systems.

Is there anything to destroy a black hole?

Black holes, the insatiable monsters of the universe, are impossible to kill with any of the weapons in our grasp. The only thing that can hasten a black hole's demise is a cable made of cosmic strings, a hypothetical material predicted by string theory.

Is spaghettification painful?

Either way, spaghettification leads to a painful conclusion. When the tidal forces exceed the elastic limits of your body, you'll snap apart at the weakest point, probably just above the hips. You'll see your lower half floating next to you, and you'll see it begin to stretch anew as tidal forces latch onto it.

How long do black holes last?

But don't expect a black hole to disappear any time soon. It takes a shockingly long time for a black hole to shed all of its mass as energy via Hawking radiation. It would take 10¹⁰⁰ years, or a googol, for a supermassive black hole to fully disappear.

Is the Milky Way shrinking?

New stars are still being created out of gas and dust at its outer edge. The Milky Way, the galaxy which contains our own solar system, is expanding and will eventually grow into its neighbour, Andromeda.

What would spaghettification feel like?

Because of the tidal forces it would feel as if you are being stretched head to toe, while your sides would feel like they are being pushed inward. Eventually the tidal forces would become so strong that they would rip you apart. This effect of tidal stretching is sometimes boringly referred to as spaghettification.

How many suns fit in a black hole?

Some black holes, called supermassive black holes, may have as much matter as 1000 million Suns! The more matter something has, and the closer an object is to that matter, the stronger the gravity. Earth's gravity is strong enough to keep all of us stuck to the ground.

What happens if 2 black holes collide?

It is possible for two black holes to collide. Once they come so close that they cannot escape each other's gravity, they will merge to become one bigger black hole. Such an event would be extremely violent.

What has survived a black hole?

A star has survived a close encounter with a black hole, but the black hole has been able to sneak a second bite. A captured star has experienced multiple close encounters with a supermassive black hole in a distant galaxy — and possibly even survived having material ripped away by immense gravitational tidal forces.

Where does a black hole end?

For all practical purposes the matter has disappeared from the universe. Once inside the black hole's event horizon, matter will be torn apart into its smallest subatomic components and eventually be squeezed into the singularity.

Will our sun become a red giant?

A: Roughly 5 billion years from now, the Sun will exhaust the hydrogen fuel in its core and start burning helium, forcing its transition into a red giant star. During this shift, its atmosphere will expand out to somewhere around 1 astronomical unit — the current average Earth-Sun distance.

What's inside a black hole?

Black holes have two parts. There is the event horizon, which you can think of as the surface, though it's simply the point where the gravity gets too strong for anything to escape. And then, at the center, is the singularity. That's the word we use to describe a point that is infinitely small and infinitely dense.

How long is 1 minute in a black hole?

on edge of Black Hole. Space and time are intertwined, called space-time, and gravity has the ability to stretch space-time. Objects with a large mass will be able to stretch space-time to the point where our perception of it changes, known as time dilation.

How long is 1 second in a black hole?

Even if we see the universe from a point very close to the apparent event horizon, the time dilates to such an extent that the time of the locations away from tne universe will be much faster (say 1 second for the observer near blak hole will be 100000 years for an observer on earth).

How many dimensions exist?

The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there's the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.
