Galileo “invented” it, Eddington foresaw its existence, Einstein understood it.
Who “invented” relatively?
We only know it “exists”, but humans are not able to control its gravity or relativity. In 1639, Galileo devised the idea of this intangible but tangible influence, when he realized that an object would all have the same state of fall, whether falling in a motionless house or on a moving ship. breast.
Einstein did not consider it “relativity”.
This term did not appear in his 1905 scientific report. Under the title “On Electrodynamics of Moving Bodies”, Einstein’s report scorned the use of the term “relativity”, and called it. is the “invariant hypothesis”, because the laws of physics all appear the same in the eyes of the observer, nothing is “relativistic” at all.
Einstein was not the author of the concept of “continuous space-time”.
The idea of time as the third dimension, related to space comes from Hermann Minkowski, Einstein’s professor and once called him “a lazy puppy”.
Einstein corrected Galileo’s equation of relativity.
Realizing that strange things can happen when objects move at near light speeds, Einstein shattered. He calculated that time slows down, and at the same time space shrinks.
Someone had deduced E = mc ^ 2 before Albert Einstein.
Friedrich Hasenöhrl, an Austrian physicist, published research on the famous formula a year before Einstein.
But why is Hasenöhrl not mentioned much?
The Austrian professor failed to associate the formula E = mc ^ 2 with relativity.
Einstein was doing the paperwork when he devised the formula “to change reality”.
At that time, Einstein was a full-time employee at an office in Switzerland, so he could only spend time researching when no one noticed. Every time the supervisor passed Einstein’s desk, the genius of theoretical physics had to hide papers related to other work.
Einstein never drank, but …
When he completed his theory of relativity, Einstein and his wife, Mrs. Mileva, hid everyone, celebrating with alcohol – a liquid, in a way, capable of changing space and time.
Feeling affection is also relative.
“I need my wife to be with me, you solve all the math problems for me,” Einstein wrote while completing his theory in 1904. By 1914, Einstein asked his wife to give up all personal relationships with by “maintaining a relationship is not an essential requirement, for many social reasons”.
The law is also relativistic.
According to Einstein, nothing is faster than the speed of light, but the speed of space itself is not limited by this law. Immediately after the Big Bang appeared, the speed of a Universe was expanding in all directions so fast that light was left behind.
We have in hand two relative things are …
Narrow relativity, which applies to objects that move at a constant speed.
General relativity, which emerged a year after special relativity, describes objects with increasing accelerations and explains how gravity works. This theory is considered to be Einstein’s most insightful view of the nature of physics.
Einstein looked at his friend’s post.
When Einstein was amazed at the formulas related to general relativity, he relied on his classmate Marcel Grossman’s autograph, because Einstein often skipped school.
Mistakes in the first calculations.
In the first version of general relativity, Einstein miscalculated the amount of light rays bent by gravity.
Fortunately, attempts to prove the hypothesis experimentally in 1914 were postponed by World War I, otherwise …
People discovered errors in Einstein’s calculation, and refused to accept Einstein’s theory.
By 1919, an experiment with an eclipse finally qualified. Eminent British physicist Arthur Eddington declared general relativity correct. The name Einstein immediately went global.
But the mistake is still …
Apparently Professor Eddington changed the final result, throwing away photos that proved Einstein’s theory was wrong.
Nobody knows it must be fine, because:
At the time of Einstein’s death in 1955, scientists still had no clear evidence to show the effect of general relativity in practice.
1960s, everything changed
Astronomers have discovered “extreme” objects that exist in space. They found that neutron stars and black holes are able to bend light through space by possessing enormous gravity.
Today, we have a very clear understanding of general relativity.
Measuring the weight of planets and distant galaxies is done by general relativity, by measuring how they bend light.
And if you still don’t fully understand “relativity”, here’s Einstein’s explanation:
“Put your hands on the hot oven and a minute will be as long as an hour. Sitting with the beautiful girl for an hour but only for a minute. That is relative ”.
