Black hole

[AJI]

I did physics 'a' level at school and I had an interest in things about the universe etc.

Just a simple question to anybody who knows.... what is today's version of a 'black hole' ?

[AndyT]

Singularity or one of Boxst's NWS threads.

[AJI]

haha ... the singularity version

Surely it would be Un-PC tp call it a "black hole" nowadays. Maybe they have changed it to a Rainbow Hole or something equally as rediculous.

Today's version of a black hole is, hang on, wait for it-

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

A black hole.

[AndrewOW]

I don't actually think its a 'hole' at all. More like a star that never ignited, but is still producing huge amounts of radiation and enormous gravitational pull.

 

That's my theory anyway

[Benyon]

I thought it was a dying star.

[AndrewOW]

I thought it was a dying star.

 

 

Or that, might I add

Well that would be wrong then innit?

 

Its an area where no radiation can escape the gravitational pull, light = radiation. As I understand it, if a large enough star collapses down at the end of its life the result will be something so dense and small that no electromagnetic radiation can escape. Surrounding radiation can be seen however.

I read that current thinking is that galactic centres may be a super-massive black hole as that would have enough pull to keep the whole galaxy rotating round it.

One school of thought is that a black hole sucks on all matter passed the event horizon and then sprays it out in a geyser in the form of a white hole somewhere along the space/time contiuum.

A black hole is a dead star which is so large it collapses in on itself; it creates so much gravity that nothing escapes, time light everything goes inwards. Only way to escape is to travel faster than the speed of light which most Scientists believe is impossible

Unless you are aware of Tachions

 

Only a Star much larger than our Sun, the real heavy weight stars, become Black holes - The sun will eventually die to become a white dwarf. Oh and the Sun is a million times the mass of the earth but still small in Astronomical terms !!

 

I study Astronomy

Am I ascendant in the cusp of Uranus?

[R Black]

well tachions, cant move slower than a light speed, but dont have infinite mass, so howz that work? i.e. bending space may not be the only way to break light speed.

So nothing at all to do with 'Uranus' then?

[grahamc]

Ok, so its a hole..........

 

 

 

........but to where and to what?

[R Black]

You fixated on that part of the anatomy then, well your out of the closet, duly noted back to the wall when yr around

 

I didnt think it was known where black holes spew into.

Thats Astrology

R 'Black' + 'Uranus' = Black hole. Just a subtle joke. Nevermind

 

EDIT: I'll get my coat

Eh?

Only something accelerating to the speed of light becomes infinitely massive, something already at that speed can have whatever mass it wants.

Oh alrighty then, that i didnt know.

Just to clarify, do these stars have to be physically bigger than our sun, or do you mean their mass must be greater?

 

 

In the mean time- a cheeky Black Hole game

if anyone fancies it.

Its a really big dyson...

I would think larger mass. Physical dimensions don't usually come into it, AFAIK.
