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
