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.
Super-distant black hole is eating half a sun a year and blasting its leftovers at Earth. Astronomers have made the most distant observation of a black hole ripping apart a star and feasting upon it, thanks to a jet of stellar "leftovers" blasted directly toward Earth.
This black hole bullet would generate a shockwave through Earth's mantle like a supersonic Mach cone. These seismic waves would reach all points on the Earth's surface. Even at the lowest mass possible for a primordial black hole it will produce the equivalent of a magnitude 4 earthquake.
Although the odds of Earth getting swallowed by a black hole, or any Solar System planet, for that matter, are low, it's definitely a real possibility.
So planets could potentially form around black holes, but that's no guarantee that they offer a life-friendly environment. On Earth, living things are hugely dependent on the light and warmth from the Sun to survive. Without the glow of a star, life around a black hole would likely need an alternative source of energy.
We are in absolutely no danger from black holes. They're a bit like tigers – it's a bad idea to stick your head in their mouth, but you're probably not going to meet one on your way to the shops. Unlike tigers, black holes don't hunt. They're not roaming around space eating stars and planets.
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.
Since the Milky Way contains over 100 billion stats, our home galaxy must harbor some 100 million black holes. Though detecting black holes is a difficult task and estimates from NASA suggest there could be as many as 10 million to a billion stellar black holes in the Milky Way.
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.
Hungry black hole shoots out bright X-ray jet 60,000 times hotter than the sun. The quasar is 100,000 billion times brighter than the sun. Astronomers stared deep into the heart of a hungry black hole, only to discover a jet of X-rays beaming out of it that is 60,000 times hotter than the surface of the sun.
Black holes are dark, dense regions in space where the pull of gravity is so strong that nothing can escape. Not even light can get out of these regions. That is why we cannot see black holes—they are invisible to our eyes. Because nothing can get out of black holes, physicists struggle understanding these objects.
New black hole simulations that incorporate quantum gravity indicate that when a black hole dies, it produces a gravitational shock wave that radiates information, a finding that could solve the information paradox. Perhaps the most enigmatic objects in the Universe, black holes embody many unsolved paradoxes.
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.
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.
Just like stars, black holes move through space, but unlike stars, they emit no light, so a "stealthy" black hole could sneak up on us, unseen. The ultimate catastrophe imaginable is that a black hole collides with Earth.
Wormholes are a classic trope of science fiction in popular media, if only because they provide such a handy futuristic plot device to avoid the issue of violating relativity with faster-than-light travel. In reality, they are purely theoretical.
Micro black holes, also called mini black holes or quantum mechanical black holes, are hypothetical tiny (<1 M ☉) black holes, for which quantum mechanical effects play an important role.
At the center of a black hole the gravity is so strong that, according to general relativity, space-time becomes so extremely curved that ultimately the curvature becomes infinite. This results in space-time having a jagged edge, beyond which physics no longer exists -- the singularity.
Solitary black holes can generally only be detected by measuring their gravitational distortion of the light from more distant objects. Gaia BH1 was discovered on 13 June 2022 by Tineke Roegiers. Gaia BH1 is 1,560 light-years away from Earth in the direction of the constellation Ophiuchus.
At a certain distance from the singularity, the escape velocity drops to the speed of light (about 186,000 miles/300,000 km per second). This distance is known as the Schwarzschild radius, in honor of Karl Schwarzschild, who first defined it.
Black holes are obviously terrifying: These crushed remnants of a massive star that exploded as a supernova are so massive that nothing, not even light, can escape its grasp.
A black hole is releasing some strange burps, baffling scientists : NPR. A black hole is releasing some strange burps, baffling scientists Astronomers were stunned to find that the black hole was emitting energy, two years after it pulled apart a star that had come too close.
In astrophysics, spaghettification (sometimes referred to as the noodle effect) is the vertical stretching and horizontal compression of objects into long thin shapes (rather like spaghetti) in a very strong, non-homogeneous gravitational field. It is caused by extreme tidal forces.
