WE ALL KNOW ALBERT EINSTEIN, he was a genius, he discovered so many things, he also predicted a lot of things about our universe. Now, one of his prediction, is proven to be right again. His General Relativity Theory has just been proven to be correct by looking at the picture of the blackhole. Amazing right? I know.
In 1905, Albert Einstein determined that the laws of physics are the
same for all non-accelerating observers, and that the speed of light in a
vacuum was independent of the motion of all observers. This was the
theory of special relativity. It introduced a new framework for all of
physics and proposed new concepts of space and time.
Einstein then
spent 10 years trying to include acceleration in the theory and
published his theory of general relativity in 1915. In it, he determined
that massive objects cause a distortion in space-time, which is felt as
gravity.
The Tug Of Gravity
Two objects exert a force of attraction on one another known as
"gravity." Sir Isaac Newton quantified the gravity between two objects
when he formulated his three laws of motion. The force tugging between
two bodies depends on how massive each one is and how far apart the two
lie. Even as the center of the Earth is pulling you toward it (keeping
you firmly lodged on the ground), your center of mass is pulling back at
the Earth. But the more massive body barely feels the tug from you,
while with your much smaller mass you find yourself firmly rooted thanks
to that same force. Yet Newton's laws assume that gravity is an innate
force of an object that can act over a distance.
Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same for all non-accelerating observers, and he showed that the speed of light
within a vacuum is the same no matter the speed at which an observer
travels. As a result, he found that space and time were interwoven into a
single continuum known as space-time. Events that occur at the same
time for one observer could occur at different times for another.
As
he worked out the equations for his general theory of relativity,
Einstein realized that massive objects caused a distortion in
space-time. Imagine setting a large body in the center of a trampoline.
The body would press down into the fabric, causing it to dimple. A
marble rolled around the edge would spiral inward toward the body,
pulled in much the same way that the gravity of a planet pulls at rocks
in space.
