BLACK HOLES

INTRODUCTION OF BLACKHOLES:

 The blackholes are extremely dense objects. their size is very lass with respect to their mass.they are black because they can't able   seen.Due to high gravity near a blackholes, not even light can escape.


HOW  BLACK HOLES ARE FORMED:


  • Blackholes are formed from explosion of massive star.
  • Even then blackholes are a rare phenomena.


HOW A STARS DIES?:
  • Star are extremely massive objects
  • When iron is produced inside them,they stop producing more energy.
  • Hence outward pressure reduce and the star implodes.


HOW TO DETECT A BLACK HOLES?:
  • Just like sun has earth and planets revolving around it,A black hole can have planets and stars revolving around it.
  • We look for such planets revolving around it something  invisible and we observe such system
  • Black holes are black .so, how can we see them.
  • They are not easy to observed and we spent a lot of time and resource for looking them

  • Now we have LIGO detector as well,through this instruments easy to observed
