A black hole is a region of spacetime whose gravitational field is so strong that nothing which enters it, not even light, can escape. The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole. Around a black hole there is a mathematically defined surface called an event horizon that marks the point of no return. It is called "black" because it absorbs all the light that hits the horizon, reflecting nothing, just like a perfect black body in thermodynamics.Quantum mechanics predicts that black holes emit radiation like a black body with a finite temperature. This temperature is inversely proportional to the mass of the black hole, making it difficult to observe this radiation for black holes of stellar mass or greater.
Objects whose gravity field is too strong for light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace. The first modern solution of general relativity that would characterize a black hole was found by Karl Schwarzschild in 1916, although its interpretation as a region of space from which nothing can escape was not fully appreciated for another four decades. Long considered a mathematical curiosity, it was during the 1960s that theoretical work showed black holes were a generic prediction of general relativity. The discovery of neutron stars sparked interest in gravitationally collapsed compact objects as a possible astrophysical reality.
I'm trying to understand why
Like a black hole in the sky
Your love is consuming my nights, my life
You're a singularity
A door opening on a new dimension
The stars and suns disappear
The whole universe lives in fear
Wiped off into nothingness, erased
Like a fantastic good-bye
Defying even my imagination
Ifs another time
And it's another space
Ifs something that science can't describe
No one has ever seen
No one has ever been
A black hole in the sky, why?
Like a black hole in the sky
You crush me from your universe
What you want you just erase without trace
Like a fantastic good-bye
Your passion is stranger than my, science fiction
Ifs another time
And ifs another space
It's something that science can't describe
No one has ever seen
No one has ever been
A black hole in the sky, why?
Like a black hole in the sky
Your love is consuming my life
Like a new world in reverse
A daughter in a new universe
A cosmic brain hard to explain
Another time another space
Something nobody can erase
Like a fantastic good-bye ...
