What is general relativity simple definition?

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 is an example of general relativity?

For example, an observer will see a ball fall the same way in a rocket (left) as it does on Earth (right), provided that the acceleration of the rocket is equal to 9.8 m/s2 (the acceleration due to gravity at the surface of the Earth).

Is general relativity E mc2?

This was first demonstrated by Albert Einstein’s Theory of Special Relativity and famously expressed in his iconic equation, E=mc2, where E stands for energy, m for mass and c for the speed of light (squared).

What are the 3 laws of Einstein?

I begin the discussion by offering the following three laws: ▸ The laws of physics are identical in all non-accelerating (that is, inertial) frames. ▸ The vacuum speed of light, c, is the same for all inertial frames. ▸ The total energy E of a body of mass m and momentum p is given by E=√m2c4+p2c2.

Can time be bent?

Science does support some amount of time-bending, though. For example, physicist Albert Einstein’s theory of special relativity proposes that time is an illusion that moves relative to an observer. An observer traveling near the speed of light will experience time, with all its aftereffects (boredom, aging, etc.)

Does gravity create time?

Yes, time goes faster the farther away you are from the earth’s surface compared to the time on the surface of the earth. This effect is known as “gravitational time dilation”.

Is general relativity just gravity?

General relativity is a theory of gravitation developed by Albert Einstein between 1907 and 1915. The theory of general relativity says that the observed gravitational effect between masses results from their warping of spacetime.

Is time a general relativity?

Time seems to follow a universal, ticktock rhythm. But it doesn’t. 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.

Does gravity exist in general relativity?

In general relativity, gravity is not a force between masses. Instead gravity is an effect of the warping of space and time in the presence of mass. Without a force acting upon it, an object will move in a straight line.

Why is c the speed of light?

“As for c, that is the speed of light in vacuum, and if you ask why c, the answer is that it is the initial letter of celeritas, the Latin word meaning speed.”

How do you explain E mc2 to a child?

What general relativity Cannot explain?

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.”
