MIND BLOWN!! Today I learned something new and totally amazing about black holes from Nova's The Fabric of the Cosmos - (Season 1, Ep 1) - What is Space? Objects (or matter) is not lost in a black hole. In fact, black holes are not holes at all! They're more like really, really, REALLY long caves. Objects that go into black holes may (or may not) be lost forever, however the INFORMATION of the item is stored on the surface of the black hole! The way I understand it is the way information for 3-D printing would be stored. And (in theory) one can reconstruct the contents of the black hole by using the information on it's surface. Of course, I still can't wrap my head around -3D printing, but I am in awe of our amazing universe!
Space is a consideration of dimension.
And a black hole is just super condensed down matter, which itself is just condensed down energy. It's NOT a cave of any kind, it's just a sphere of matter and energy that eats other matter and energy. If you were to expand some solid matter sufficiently, you would get lots of energy. If you expand what we call a black hole (so named because not even light can escape from it), you would get some regular matter which is made up of the elements on the Periodic Table. Now, here's a conundrum for you to ponder; Since a black hole is made up of matter which is so tightly compacted that the molecules in it cannot move at all, no vibration to them, then it's infinitely cold, right? But, since no energy can escape from it, it has all of the heat and energy in it from all of the various objects which it has glommed onto, so by logic, it has to be infinitely hot as well!! So which is it?
3D printing is not much more than putting icing on a cake with a pastry bag or syringe. You decide where you want to squirt the stuff out of the nozzle, and then do it!
According to the reference I cited, what I shared is correct. Please site you source for the information you have shared.
@JustAskMe
If you were to take someone who has lived in a city all of their life, and put them out in the country, they may not like it because the dimensions of the boundaries are very far apart, they have too much space to deal with. If you take someone who has lived out in the wild all of their life, and put them into a crowded and congested city, they may not like it because things are too close together, there's not enough space between the boundary lines. So, here we can see that it's our considerations that define our spaces. What we feel comfortable with is due to our considerations about it. Sit with your eyes closed in a quiet place, and imagine your point of view shrinking down to where you could see an atom. Then switch over to expanding your point of view to where Saturn would look like a little pea in the palm of your hand. Keep going back and forth with those two frames of reference for about 15 minutes and then see what your considerations are regarding space.
As to what a black hole is, it really is a perfectly smooth sphere because it's gravity is uniform in all directions and is immensely strong. A drop of oil falling though a vacuum would be a perfectly round sphere as well, because there would not be any gas molecules rushing past it to disturb the surface. The surface tension of the oil drop acts like a gravitational pull, it's equal in all directions, thus it makes the drop into a perfect sphere.
The correct word there is cite, not site.
Look, I understand you're offended about the sexual deviant thing, but I used the "cite" correctly, and you failed to cite your source. With no source, I have every right and reason to dismiss your response.
@JustAskMe Books by professionally qualified people are available, including Eric Lerner’s “The Big Bang Didn’t Happen” and Donald Scott’s “The Electric Sky”. At www.newtoeu.com you can download a free PDF document that does not require a degree in astronomy or physics to understand. It all began ninety years ago with an attempt by a Catholic priest to use mathematics to prove the Bible’s Genesis story.
@yvilletom I normally don't argue with folks who come off as trolls because it's a waste of time, but lets say for a moment that you are not a troll. I can't take you back to 4th grade and teach you the scientific method. This is what scientists use while conducting experiments and making observations. Without evidence, science would have no opinion.. And I don't know why you refuse to believe the evidence presented by folks who are much smarter than you. You either simply want to argue, believe you know better than those educated in the field, or are a complete moron. In any of these cases, I haven't time for you.

Posted by starwatcher-alSolar minimum was in 2019 so the sun is ramping up in flares, spots and prominences.
Posted by starwatcher-alI missed the early phases of the eclipse but the clouds mostly left during totality. All in all a great eclipse. Next one is Nov. 8-22

Posted by starwatcher-al Did you know that you can see Venus in the daytime?
Posted by starwatcher-alOne of these days I think that I'll figure out this Nikon.
