BLACK HOLE -Hidden mystery of universe - Dr Stephen Hawking

 

BLACK HOLE

Aap sbne Dr Stephen hawking ka naam  toh suna hi hoga , Stephen hawking ek brilliant Scientist the jinhone apni puri life blackhole par research me bita di.

Black hole based on theory of general relativity par

Ab  Black hole ke ander toh ham ja nhi sakte or galti se sahi salamat chale bhi gaye toh bhi wapis bahar nhi aa payenge

Akhir blackhole k andar chal kya raha?

Ye ek tarah se universe ki mystery h jo hamare ankho k samne hai bhi  or nhi bhi

Black hole k irdh girdh ek region hai jise event horizon kehte h

Event horizon ek tarah ki boundary h agar aap event horizon k bahar ho toh  aap safe ho lekin agar apne event horizon ko cross kr liya aap kabhi baahar nhi aa  paoge

Dr. Stephen hawking ne event horizon pe hi research kiya  k akhir ye kaise kaam krta h Toh unhone paya k k event horizon ek hologram k jaise kaam krta h

Dr Stephen hawking ne ek formula diya jisse ham black hole k andar ki energy ka pata laga sakte h bs black hole k satah ka area pata  kar k , sirf black hole k andar ki energy ka pata laga k hame black hole k bare me bahut kuch pata chal sakta h 

wo formula h

                                                                E=MC²

E= energy of any particle

M= mass of body

C²= speed of light squared                               

Agar koi bhi chiz black hole k andar jayegi toh uska mass badhega matlb event horizon ka radius bhi  sath hi sath badhega

Dr Stephen hawking ne hawking radiation ki bhi khoj ki jo ye h

Hawking radiation is black-body radiation that is predicted to be released by black holes, due to quantum effects near the black hole event horizon.

 Black hole spacetime ka aisa kshetra hai jaha gravity itni strong hoti hai ki waha se koi bhi particles or electromagnetic radiation jaise light bhi escape nhi kar pata.
