Simple Relativity – Understanding Einstein’s Special Theory of Relativity
What is theory of relativity? [1]
Albert Einstein’s theory of relativity is actually two separate theories: his special theory of relativity , postulated in the 1905 paper, The Electrodynamics of Moving Bodies and his theory of general relativity , an expansion of the earlier theory, published as The Foundation of the General Theory of Relativity in 1916. Einstein sought to explain situations in which Newtonian physics might fail to deal successfully with phenomena, and in so doing proposed revolutionary changes in human concepts of time, space and gravity.
Following this logic, Einstein theorized that time must change according to the speed of a moving object relative to the frame of reference of an observer. Scientists have tested this theory through experimentation – proving, for example, that an atomic clock ticks more slowly when traveling at a high speed than it does when it is not moving
Relativity was a stunning concept at the time; scientists all over the world debated the veracity of Einstein’s famous equation, E=mc2, which implied that matter and energy were equivalent and, more specifically, that a single particle of matter could be converted into a huge quantity of energy. However, since the special theory of relativity only held true in the absence of a gravitational field, Einstein strove for 11 more years to work gravity into his equations and discover how relativity might work generally as well.
Explaining Einstein’s theory of relativity is no easy feat – DW – 11 [2]
Explaining Einstein’s theory of relativity is no easy feat. The first thing you should know if you read this is I know nothing about Albert Einstein’s Theory of Relativity – apart from the fact that it’s Einstein’s theory and it has something to do with relativity
Einstein’s theory of relativity consists of two theories: general relativity and special relativity. They are Einstein’s theories on how we should interpret motion between relative points in time and space, and how matter bends (or curves) the time-space continuum, giving us what we perceive to be gravity.
Apparently, Einstein stopped wearing socks as soon as he realized as a young man that the big toe always makes holes in them.. The laws of physics are the same for all observers moving at a constant speed.
Einstein’s general relativity theory is questioned but still stands ‘for now,’ team reports [3]
More than 100 years after Albert Einstein published his iconic general theory of relativity, it is beginning to fray at the edges, said Andrea Ghez, UCLA professor of physics and astronomy. Now, in the most comprehensive test of general relativity near the monstrous black hole at the center of our galaxy, Ghez and her research team report July 25 in the journal Science that Einstein’s theory holds up.
“We can absolutely rule out Newton’s law of gravity. Our observations are consistent with Einstein’s general theory of relativity
It cannot fully explain gravity inside a black hole, and at some point we will need to move beyond Einstein’s theory to a more comprehensive theory of gravity that explains what a black hole is.”. Einstein’s 1915 general theory of relativity holds that what we perceive as the force of gravity arises from the curvature of space and time
What is Einstein’s Theory of Relativity? [4]
In the history of science and physics, several scholars, theories, and equations have become household names. In terms of scientists, notable examples include Pythagoras, Aristotle, Galileo, Newton, Planck, and Hawking
But the most famous and renowned is arguably Albert Einstein, Relativity, and the famous equation, E=mc2. In fact, Relativity may be the best-known scientific concept that few people truly understand.
And the term “Relativity” itself goes back to Galileo Galilee and his explanation for why motion and velocity are relative to the observer. As you can probably tell, explaining how Einstein’s groundbreaking theory works require a deep dive into the history of physics, some advanced concepts, and how it all came together for one of the greatest minds of all time!
Sharpening Einstein’s theories for a better understanding of the universe [5]
Over a hundred years ago Einstein formulated his theory of general relativity. No physicist has yet reconciled the two into a theory of quantum gravity that can be confirmed experimentally

relativity [7]
Among the outstanding advances in science will always stand Albert Einstein’s theories of relativity—the problem of how physical laws and measurements change when considered by observers in various states of motion. These theories forced revision of all fundamental thinking about time and space
And the theories gave scientists the mathematical framework they needed for atomic research and for releasing nuclear energy.. Einstein came up with his first theory of relativity, called the theory of special relativity, in 1905
The speed of light is thus the “speed limit” of the universe. Special relativity also showed that mass and energy are the same physical entity and can be changed into each other.
Einstein’s genius changed science’s perception of gravity [8]
Albert Einstein opened humankind’s eyes to the universe.. Before Einstein, space seemed featureless and changeless, as Isaac Newton had defined it two centuries earlier
But Einstein looked at space and time and saw a single dynamic stage — spacetime — on which matter and energy strutted, generating sound and fury, signifying gravity.. Newton’s law of gravity had united the earthly physics of falling apples with the cosmic dances of planets and stars
It took an Einstein to figure out gravity’s true modus operandi. Gravity, Einstein showed, did not just make what goes up always come down
Princeton scientists say Einstein’s theory applies beyond the solar system [9]
A team led by Princeton University scientists has tested Albert Einstein’s theory of general relativity to see if it holds true at cosmic scales. And, after two years of analyzing astronomical data, the scientists have concluded that Einstein’s theory, which describes the interplay between gravity, space and time, works as well in vast distances as in more local regions of space.
Ever since the physicist Arthur Eddington measured starlight bending around the sun during a 1919 eclipse and proved Einstein’s theory of general relativity, the scientific world has accepted its tenets. But until now, according to the team, no one had tested the theory so thoroughly and robustly at distances and scales that go beyond the solar system.
Other scientists collaborating on the paper include Tobias Baldauf, Lucas Lombriser and Robert Smith of the University of Zurich and Uros Seljak of the University of California-Berkeley.. The results are important, they said, because they shore up current theories explaining the shape and direction of the universe, including ideas about “dark energy,” and dispel some hints from other recent experiments that general relativity may be wrong.
Theory of relativity [10]
The theory of relativity usually encompasses two interrelated physics theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively.[1] Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its relation to the forces of nature.[2] It applies to the cosmological and astrophysical realm, including astronomy.[3]
In the field of physics, relativity improved the science of elementary particles and their fundamental interactions, along with ushering in the nuclear age. With relativity, cosmology and astrophysics predicted extraordinary astronomical phenomena such as neutron stars, black holes, and gravitational waves.[3][4][5]
Michelson, Hendrik Lorentz, Henri Poincaré and others. Max Planck, Hermann Minkowski and others did subsequent work.

General relativity introduces the equivalence of mass and energy.. General relativity includes reference systems moving faster than the speed
General relativity includes accelerating reference systems.. Einstein’s theory of Special Relativity, proposed in 1905, deals with physics in the absence of gravity and is limited to objects moving at constant speed in a straight line, i.e., inertial reference frames
A Century Ago, Einstein’s Theory of Relativity Changed Everything [12]
A Century Ago, Einstein’s Theory of Relativity Changed Everything. — By the fall of 1915, Albert Einstein was a bit grumpy.
He had split up with his wife, and she had decamped to Switzerland with his sons.. A friend, Janos Plesch, once said, “He sleeps until he is awakened; he stays awake until he is told to go to bed; he will go hungry until he is given something to eat; and then he eats until he is stopped.”
The German mathematician David Hilbert was breathing down his neck.. 25, 1915, he set down the equation that rules the universe
