UM-Bot Posted August 10, 2017 #1 Share Posted August 10, 2017 A new study has revealed that there are actually tens of millions of black holes in our own galaxy alone. http://www.unexplained-mysteries.com/news/310555/milky-way-galaxy-is-riddled-with-black-holes 5 Link to comment Share on other sites More sharing options...
paperdyer Posted August 10, 2017 #2 Share Posted August 10, 2017 Kind of scary. Do we actual know if these are actually holes of minimal thickness or a tunnel? Movies seem to make the black holes seem like tunnels. I wonder if we'll ever know what's inside one of these. If would have to be something incredibly dense to generate the gravity. Maybe there's a group of items creating the gravitation pull. Just another mystery of the universe that may never be solved. 1 Link to comment Share on other sites More sharing options...
Gingitsune Posted August 10, 2017 #3 Share Posted August 10, 2017 Last time I read about black holes, there were two therories. Either they are tunnels to somewhere else, or they are so heavy that the atoms crumble into impossibly dense matter. Which mean, first the electrons no longer run around the core but are pushed down on the core of proton and neutron, then the core itself crumble into a more compact mass of quarks. 1 Link to comment Share on other sites More sharing options...

taniwha Posted August 11, 2017 #5 Share Posted August 11, 2017 I think it would be so fascinating to watch a black hole descending upon Earth, especially if you were lucky enough to see from directly underneath. Imagine what you could learn! Link to comment Share on other sites More sharing options...

Imagine what you could learn! There would not be much to see or feel until you crossed the event horizon. Check out one of the TED talks on black holes. Neil DeGrasse Tyson does on. I am thinking it would not be cool. Not many people in the tunnel school, Hawking, Susskind, and others think that is purely science fiction. 2 Link to comment Share on other sites More sharing options...
Susanc241 Posted August 11, 2017 #7 Share Posted August 11, 2017 I have always assumed they were solid bodies (like other visible planetary bodies or suns) but of such intense density that gravity outweighed light etc. Would genuinely like to know if anyone knows that it is not possible for them to be solid spheres. 1 Link to comment Share on other sites More sharing options...

Grandpa Greenman Posted August 11, 2017 #9 Share Posted August 11, 2017 That is really no surprise the galaxy is full of black holes, when you think about them as being stellar remnants and the age of the universe. Kind of like those old concert tee shirts I bought in the 70's, full of holes. 2 Link to comment Share on other sites More sharing options...
thelion318 Posted August 11, 2017 #10 Share Posted August 11, 2017 I don't understand why this is scary to some people. The Earth is 5 billion years old and has not been affected by one of these numerous black holes before. Just because they are there doesn't mean anyone is in any immediate danger, they are very far away. Link to comment Share on other sites More sharing options...

Unfortunately, we don't have a scale for how fast materials can travel within the CMB before their bonds break, this knowledge might be beyond our years. 13 hours ago, taniwha said: I think it would be so fascinating to watch a black hole descending upon Earth, especially if you were lucky enough to see from directly underneath. Imagine what you could learn! https://en.wikipedia.org/wiki/Kugelblitz_(astrophysics) "In theoretical physics, a kugelblitz (German: "ball lightning") is a concentration of light so intense that it forms an event horizon and becomes self-trapped: according to general relativity, if enough radiation is aimed into a region, the concentration of energy can warp spacetime enough for the region to become a black hole (although this would be a black hole whose original mass-energy had been in the form of radiant energy rather than matter)." If you were on the Earth you wouldn't be able to tell a Kugelblitz was occurring as light would be travelling at too high of a speed to give you a forewarning.

Who knows if there isn't a small one headed our way that we just haven't found yet. Link to comment Share on other sites More sharing options...

Crystal Rose Posted August 13, 2017 #15 Share Posted August 13, 2017 This topic made me think of something.... if gravity can beat light... can it become a speed? So instead of speed of light, it would be speed of gravity? Or perhaps make light go faster? 1 Link to comment Share on other sites More sharing options...
