Asked by rooksy to Jimmy on 13 Mar 2013.
Question: When 2 pulsars collide, does it create a vast Gravitational void; a black hole?

James Holloway answered on 13 Mar 2013:
To crease a blackhole you have to get over a certain density, that is you have to cram enough stuff into a small space.
Now if two pulsars merged they would form a new pulsar. If that new pulsar now had enough gravity (from all that new stuff) to overcome the force* of the particles pushing away from each other then the whole thing would collapse into a blackhole!
The key is to have enough stuff in the first place to make enough gravity.
*the force holding pulsars up against gravity is called ‘neutron degeneracy pressure’, it might be a bit technical right now though.

you’ve sprlled create wrong

haiii u have spelled SPRELLED insted of SPELLED :]

whos rooksy??? i think that it is hhhhhhhhhhhhhh .REBEKAH!!!!!!!!!!! ok well see ya!
jennyxd9 commented on :
its very intersting the science you can do and this website is cool
aklebash commented on :
yes you are wrong a black hole is created when a giant star comes to the end of its ife and collapses in on itself so the gravitional pull is so great that nothing escapes from it
Jimmy commented on :
Haha! Yeah I am terrible at spelling. You’ll find lots of mistakes in my stuff 🙂

and ive spelled spelled wrong

Hi Jimmy!
I want to know do you spend time doing explotion??
amyb89 commented on :
I never new that!

What are black holes?
Jimmy commented on :
@aklebash You’re quite correct! Some big stars to end their lives as black holes.
Did you know some people were afraid that we could accidentally create black holes on Earth when we turnt the LHC on (big machine at CERN)?
The LHC smashes stuff together so hard that they were afraid the matter would be compressed into a small enough space that it would turn into a black hole.
