my question is: Where is the math to prove a black hole..since it against all phyics to exist? are you just guessing?
How come it isn’t just a black ball? no light can escape so you can’t see a hole or a ball..but the ball makes more sense since the numbers would work and everything in nature under pressure is squeezed into a ball shape. ( a little tiny..highly massive ball,smaller than a neutron star. ) your welcome Hawking..

1)I am bsically a MBA student but i am studing astronomy right from my childhood.I want to get into the research department of any observatory.How shall i get into it

2)What is a hypermassive black hole

3)How does the inner part of the star collides to form either a neutron star or a black hole.

hi. I am prerna batra of class ixth.my biggest curiosity is about aliens and black holes.Like for aliens:
who are they?are the stories such as roswell case true…or is it just 4 publicity?n my biggest ques.
DO THEY REALLY EXEST?
and as per black holes…
My major ques. would be “what would happens if by chance we would get into a black hole?where would we lan?will the time be same?”

Hello
I am confused about the speed at which radiation travels.
Is the speed of light the the maximum speed of travel?
Which part of the radiation coming from the sun travels at that speed? visual spectrum or all radiation? or different spectrums or radiation such as radio or gamma rays at different speeds?
Radiation coming from different stars do they travel at the speed of light?
Does some of the radiation travel at less speed than light?
Do all other particle travel at less speed than light?
What determines their difference in speed?
Confused about the speed of light and what exactly travels at the speed of ligh?
If some radiation does not travel at the speed of light then which radiation and why?
where is the deliniation?

I am an engineering professor emeritus (University of Cincinnati) and, among other things professional I am involved with the Institute for Learning in Retirement within our College of Continuing Education. In it I have been teaching a series of courses entitled, “Our Glorious Universe,” in which I talk about the beginning and end of the Universe and just about everything in between including an introduction to Newtonian, Relativity, and quantum physics. The attendees are mostly retired professionals ranging in age from about 55 – 85 and seem to be vitally interested in this subject despite their advanced years. The course is taught twice each academic year and I update it constantly. Many pertinent questions arise and I would be interested in participating in any online discussions that you plan.

According to some people’s opinions, being a teacher means that you have know everything, but I see that it IS a wrong conception.

I write about astronomy. I wish I taught in school, but being unable to, I have written about 300 short descriptions of special objects. Occasionally, readers ask fascinating questions. Yesterday one of them asked if gas clouds collapsing into stars might be dense enough to allow a person to breathe in space. I told him that while I did not have the numbers right at hand, I suspected that the density was maybe a thousand times thinner than Earth at sea level. I then promised to look it up.

In a few minutes, I had located the answer at several places, including Ohio State University. I shocked myself by discovering that our atmosphere was not a thousand times thicker than these molecular gas clouds, but rather a hundred trillion times. This lead to questions and answers about the process of collapse and the math behind the ideal gas law.

Yes, I wish I taught in school.
