What is general relativity? Essentially, it’s a theory of gravity . The basic idea is that instead of being an invisible force that attracts objects to one another, gravity is a curving or warping of space. The more massive an object, the more it warps the space around it.
What exactly is relativity?
What is general relativity? Essentially, it’s a theory of gravity . The basic idea is that instead of being an invisible force that attracts objects to one another, gravity is a curving or warping of space. The more massive an object, the more it warps the space around it.
What does relativity mean in simple words?
1a : the quality or state of being relative . b : something that is relative. 2 : the state of being dependent for existence on or determined in nature, value, or quality by relation to something else.

What is the meaning of the theory of relativity?
The theory of special relativity explains how space and time are linked for objects that are moving at a consistent speed in a straight line . ... Simply put, as an object approaches the speed of light, its mass becomes infinite and it is unable to go any faster than light travels.
What is an example of relativity?
One example of relativity is to imagine two people on a train playing ping-pong . The train is traveling at around 30 m/s north. When the ball is hit back and forth between the two players, the ball appears to the players to move north at a speed of around 2 m/s and then south at the speed of 2 m/s.
How did Einstein figure out relativity?
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, according to Wired.
What does E mc2 mean in simple terms?
Einstein’s Big Idea homepage. E = mc 2 . It’s the world’s most famous equation, but what does it really mean? “ Energy equals mass times the speed of light squared .” On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.
What is the difference between the two theories of relativity?
The “General Theory of Relativity’ is related to gravity. ... The difference between the two theories is that the theory of general relativity throws light on the force of gravity with respect to curving four-dimensional space-time . As per Einstein, the accelerative and gravitational forces are equal and same.
Why is E mc2 so important?
Einstein’s greatest equation, E = mc 2 , is a triumph of the power and simplicity of fundamental physics . Matter has an inherent amount of energy to it, mass can be converted (under the right conditions) to pure energy, and energy can be used to create massive objects that did not exist previously.
What is the formula for relativity?
Einstein went on to present his findings mathematically: energy (E) equals mass (m) times the speed of light (c) squared ( 2 ), or E=mc 2 . The secret the equation revealed—that mass and energy are different forms of the same thing—had eluded scientists for centuries.
What’s the opposite of relativity?
Antonyms & Near Antonyms for relativity. autonomy , self-determination, sovereignty.
What is Einstein’s theory of relativity for dummies?
The principle of relativity: The laws of physics don’t change, even for objects moving in inertial (constant speed) frames of reference . The principle of the speed of light: The speed of light is the same for all observers, regardless of their motion relative to the light source.
What did Einstein mean by time is relative?
In the Special Theory of Relativity, Einstein determined that time is relative—in other words, the rate at which time passes depends on your frame of reference . ... The effect of time slowing down is negligible at speeds of everyday life, but it becomes very pronounced at speeds approaching that of light.
What is E mc2 used for today?
Many everyday devices, from smoke detectors to exit signs, also host an ongoing, invisible fireworks of E = mc2 transformations. Radiocarbon dating, which archeologists use to date ancient material, is yet another application of the formula.
Why is theory of relativity important?
The theory explains the behavior of objects in space and time , and it can be used to predict everything from the existence of black holes, to light bending due to gravity, to the behavior of the planet Mercury in its orbit. The implications of Einstein’s most famous theory are profound.
