Earth Swallowed by Black Hole

Ok, this is disturbing.

Yup, and a brick can fall onto our heads too on the way to work. Life's dangerous.

There is some truth.

Think about this, supposed a black hole is rpping Jupiters moons off meaning lets say its tne times the distance and has 100 times the graviational field. Those moons would simply enter more eccetric orbits, if it got much closer they would enter hyperbolic orbits and be thrown from our system. That hole is traveling maybe at

100 km/sec relative to Earth, and it might be passing in a normal or anti-normal trajectory which means more than likely it would shift the inclination of the moons orbit.

In terms of earth, the same problem, if it is traveling at Earth at 100 km per second and Mach speed is 300 metrer per second it would not suck the atmosphere off of Earth, Instead the Earth would start to deform into a teardrop as it was serially compressed into the singularity.

The gas in Earths atmosphere and the heat created by the deformation would cause gas to spin around the polar ends of the hole causing it to belch x-rays and gamma rays sufficient to expel all the gas above and below the hole from the galaxy.

Not terribly worried about it... we're already orbiting a supermassive black hole, and I feel fine..

[Shpaget]

When I was a kid, old folks used to scare kids with the Bogeyman. These days it seems the black holes are the worst thing ever.

They present the scenario as if it's something that happens at least twice a year, so we should know what to expect and not like the most remotely possible event ever conceived, which it is much closer to.

in the end, everyone dies

lol

you may also have microscopic black holes

perhaps not dangerous but still interesting

It's silly to worry about this. ANY star wandering through our solar system would disrupt the planetary orbits and probably get the Earth bombarded by asteroids. And stars far outnumber black holes. But stars are so far apart that this is a very very unlikely thing to happen during the lifetime of the Earth.

[Kaos]

This is comparable to the fear that an aircraft carrier falls on your head. It is quite deadly, including everything around you, but it will not happen.

This video reminded me of

If there was a stellar-mass black hole anywhere near our solar system, we would be seeing its effects in the form of unexplained abberations in the orbits of the other planets in our solar system.

We're not.

A black hole isn't going to suddenly jump out at us like Freddy Fazbear. They are finite objects, with finite mass, travelling at finite velocity, and we'll see their effects long before they actually get here. If they ever do. Not gonna hold my breath waiting.

There was a pretty good short story once by Fritz Leiber called 'A Pail of Air', about survivors on Earth coping with the aftermath of a tiny black hole shooting through the solar system and pushing the Earth into a solar-escape orbit.

I'd actually prefer not to see them in advance

Oh man - it's been a long long time since I read that. Good story though. Greg Bear's 'The Forge of God' is kind of relevant to this thread too.

If a black hole or neutron star was headed for our solar system, we would be able to see its effects and locate it decades before it did us any harm.

Disagree. Advance warning will be our ace in the hole........
