Definitions and Meaning of black hole in English
black hole noun
- a region of space resulting from the collapse of a star; extremely high gravitational field
Description
A black hole is a region of spacetime where gravity is so strong that nothing, including light and other electromagnetic waves, is capable of possessing enough energy to escape it. Einstein's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of no escape is called the event horizon. A black hole has a great effect on the fate and circumstances of an object crossing it, but it has no locally detectable features according to general relativity. In many ways, a black hole acts like an ideal black body, as it reflects no light. Quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is of the order of billionths of a kelvin for stellar black holes, making it essentially impossible to observe directly.
કૃષ્ણ વિવર અથવા કાળું કાણું એક એવો સૈદ્ધાંતિક વિસ્તાર છે જેની પાસે એટલું શક્તિશાળી ગુરુત્વાકર્ષણનું ક્ષેત્ર છે કે જો કોઇ જાતનું દ્રવ્ય અથવા કિરણોત્સર્ગ એના કેન્દ્રથી અમુક અંતરથી નજીક આવે તો એ એના ખેંચાણથી છૂટી શકે નહિ. જેમ પ્રકાશના કિરણો પણ છૂટી ના શકે તેમ આવી વસ્તુઓ કાળી લાગે અને તેથી એનું નામ કાળું કાણું (Blackhole) અપાયું. તેની હાજરી ફક્ત તેના અન્ય પદાર્થો સાથેની પ્રતિક્રિયા વડે જ જાણી શકાય છે.
