I promise, this is my last of my opening posts in science today (god, I love it). I enjoyed the posts on star formations (when and why etc.), but I had another 'gee whiz' ? about black holes.
First of all, they seem fantastic that they exist, despite being in Albert E's equations and he didn't even think that they (black holes) would actually exist. But they do (exist). Also, a greater and faster expansion of the universe continues today. Unexpected and surprising to those in the know about these things.
So, if (1) universe is expanding (most noticeable in-between the galaxies) and (2) there are greater and greater in numbers of black holes being created since day 1 AND according to Hawkings, black holes exist for a very long time but will eventually dissipate over perhaps trillions of years, that the ...
increasing number of black holes in the universe on a daily basis power the faster expansion of the universe (e.g. they both seem to increase in step w/ each other).
Physics break down within black holes (unable to adequate express equation wise, events within black holes). Could some facet of the already identified dimensions (26 (I think) was the last number of dimensions speculated about by those in the know here) be interacting in some way unknown to us to loop about and feed the ever increasing expansion of the universe?
That's my ? in a nutshell. I hope I wasn't rambling on, but this has been in my mind for a long time, and I was curious what you all think.
A question that perhaps someone can answer for me. I do read quite a bit and so forth, but 1 thing still escapes me. We all (most of us) know that stars form by hydrogen / helium gases (in clouds scattered throughout the universe) collapsing under the weight of so much gas, and eventually, after a certain point, enough gases and pressure has built up that nuclear fusion starts, and you have 'liftoff' or a brand new star.
I am assuming that this process occurs once a certain threshold of gases and pressure is achieved.
However, there are massive stars that from 10 to a 1000 times the size of our sun.
Why didn't these massive stars start burning as stars when they already had enough pressure and material after 1 solar mass of material available, e.g., like our own sun? Or put in another way, how did these super-sized stars manage to gather so much material before igniting into a star? If it ignited at 1 solar mass (like our own sun), then all other incoming gases etc. would have been pushed away by the solar winds.
So, how does a star gather up so much more material than our own sun before igniting?
Thanks for any thoughts and light you may shed on this (pun was not intended, purely accidental)!?
