hello and here you can say anything you know about blackholes goodluck
Keep up to date with the Space calendar 2022: Rocket launches, sky events, missions and more!
If your looking for information about black holes a good place to start is the Wikipedia article on them, which can be found here:starialove":19rkm17y said:hello and here you can say anything you know about blackholes goodluck
Well, they're not exactly holes in the conventional sense. They're super-dense objects. There may be a ball of stupendously dense stuff in the middle, or it may be compressed into a singularity, or it may have winked itself out of existence entirely leaving only its gravity well behind -- beyond the event horizon, you can't see and the difference may be academic anyway.Technetium":30ts1vlw said:Generally... Black holes are holes in space that have an extremly high gravitational pull that pulls everything including light into it.
i'm not in any sense doubting you as my knowlege on anything outer space comes from the series "The Universe" lol, but it was my understanding the black holes didnt move. explain if i'm wrong. i'm curious! lolneilsox":3r3fbf8d said:there likely are many trillionSince several percent of the super nova, the past 13.6 billion years produced a black hole and most of them have likely s of black holes in the universe, billions of black holes cruising our galaxy.

The population of identified Neutron Stars of the Milky Way & the Magellanic Clouds combined is in the neighborhood of 2000. I'd like to know where you got this "billions of BH's" in the Milky Way from?neilsox":16fm5zl2 said:Here are some bits of information that often don't get mentioned. We can't see black holes, but we have enough inferences to be quite sure about some of the black holes at the center of galaxies, plus a few that are only a few solar mass, elsewhere in our galaxy. Since several percent of the super nova, the past 13.6 billion years produced a black hole and most of them have likely gained more mass than they lost by Hawking's radiation (if Hawking's radiation occurs) there likely are many trillions of black holes in the universe, billions of black holes cruising our galaxy. A fast black hole could pass through our solar system with only a few years warning. Non rotating black holes are easier to analyze, but likely nearly all black holes rotate rapidly/even faster than typical neutron stars, which may also be very numerous. Black holes with low mass, such as the mass of a large mountain, have been hotly debated, but none have been detected, possibly because their event horizon would have microscopic radius. Neil
