No. The timeline of the Universe extends infinitely far into the future. It's more accurate to say that the lifetime of the largest black hole is just a quick flash in the infinitesimally brief young universe where there is actual structure present above the subatomic level. If you want to argue &q...

Conclusion, black holes last forever, in all practical terms. No. The timeline of the Universe extends infinitely far into the future. It's more accurate to say that the lifetime of the largest black hole is just a quick flash in the infinitesimally brief young universe where there is actual struct...

Off topic Thank you, Ann It seems (?) Chris and I are being warned we are off topic?? So I sent you a private message, Chris. No, I don't think so. Topicality isn't a big deal around here, as long as it's sane and civil. 'Sane?' 'Sanity.' And who is to define those words? HAHAHAHAHAHAHAHAHA. (Oops.)

Off topic Thank you, Ann It seems (?) Chris and I are being warned we are off topic?? So I sent you a private message, Chris. Is your name Ann :?: (You'll know when you've been slapped on the hand. It comes as a private message from one of the moderators.) Nope, my name is not Ann, though my eldest...

Amazing, zero to 17000 mph plus perfectly tied, over and over again. And yet, nothing but simple Newtonian and Keplerian math... arithmetic, really... that any 15-year old should be able to work out. (Not to discount the complex engineering problems that needed to be solved, but the Universe really...

I'm perfectly copacetic with warmings 's visualization of matter " (black hole or star, it doesn't really matter) " consuming space (i.e., converging spacetime). If there had been a lot more matter then all of space would have been consumed (and time ended) in the The Big Crunch . However...

So matter falls into the BH but not the spacetime that is surrounding the matter? Correct! Keep in mind that matter does not have to fall into the black hole. A star, or planet could orbit a black hole in the same way as the Earth orbits the Sun or the Moon orbits the Earth. Pretty picky black hole.

Hawking has said there is no event horizon .. so what else is there not?

1) Quarks and electrons are also considered to be mathematical points with the attributes of mass, spin, charge and a characteristic dimension. 2) Everything that enters a classical BH quickly falls into a singularity in accord with its own personal time frame . As far as the rest of us are concern...

I like pineapple and I like pizza; but I never tried them together! I think I'll stick to beef; mushroom; & onion with lots of sauce and mozzarella cheese! :wink: I like the pineapple on an ice cream sundae! :D I had to learn to enjoy pineapple on pizza, but once learned, is very pleasant, slow...

when everything that enters it is said to go into a singularity .. which as I understand it at this point is a mathematical point only .. having no mass at all. Or is my current understanding completely wrong? (As it could easily be as my most recent reading easily points out that singularities are...

Visualizations can lead to what are said to be imaginations, so, in my 'imagination,' the flare arching out from the upper end actually left side in the image which seems to be the originating end of the flare actually appears to end at a massive knobbly like mass which SEEMS to me to actually 'dra...

This is a very pleasant thread .. I used to buy cut flowers for my bachelor pad .. made it nice and homey .. and the honeys enjoyed them too .. I guess I should say the honey bees, but that might sting.

What part of the universe do you liken the sink to? The sink is spacetime. The drain is a mass (black hole or star, it doesn't really matter). The water is matter. I'm perfectly copacetic with warmings 's visualization of matter " (black hole or star, it doesn't really matter) " consuming...

But that question was answered several times. I fail to see the answer. Perhaps because it's cloaked in exclusive language in so many pages of posts. A simple yes or no might satisfy me as to someone else's opinion though. No. And that's not an opinion, but an observation based on the consequences ...

To participate in discussions? Certainly not. To suggest new theories or new interpretations of mainstream theory? Yes, such qualifications are likely to be important. You consider that I am suggesting a new theory? I don't know what you're suggesting, because you are inventing terminology that isn...

In other words a person needs to have super advanced degrees in the mathematics of cosmology to participate in discussions here? Of course not. But some subjects can't be sensibly framed in common English, so any attempt to ask or answer questions devolves into a discussion of nomenclature rather t...

In any case, however, my earlier comment stands: if people want to talk about bending, or ripping, or devouring spacetime, those concepts need to be framed in the math of GR. The words by themselves mean little or nothing. In other words a person needs to have super advanced degrees in the mathemat...

Wikipedia wrote: Venus shows no evidence of active plate tectonics. ... One explanation for Venus's lack of plate tectonics is that on Venus temperatures are too high for significant water to be present.[71][72] The Earth's crust is soaked with water, and water plays an important role in the develo...

So, if a Black Hole is collapsed space time .. then the Black Hole must be always eating space time .. otherwise it cannot eat anything, that is, if it's a sealed unit. A black hole is not collapsed spacetime. A black hole forms when matter, usually a star, collapses. When matter collapses its matt...

Spacetime isn't a field. In any case, however, my earlier comment stands: if people want to talk about bending, or ripping, or devouring spacetime, those concepts need to be framed in the math of GR. The words by themselves mean little or nothing. This quote from Oxford University may interest you....

You'd have to begin with a mathematical description, within the framework of GR, of what "devouring space time" even means. Isn't spacetime a four dimensional field? Black holes move through spacetime just like stars and planets, but none of these objects, even the most Super Massive Blac...
