can some one tell me about einestein's theory?i am a 14 year old so no higher physics talk.?

Answer 1

Special relativity: between two uniformly moving observers, there is no way to tell who is "moving" and who is "at rest". This means there is no physics experiment one could do to distinguish between them, which means the speed of light is the same for both of them. This has deep consequences for the geometry of space and time. It turns out that space and time work together in a 4-dimensional geometry which is commonly called "spacetime" and has some weird properties which manifest as time dilation and length contraction.

General relativity: an extension of these ideas to cover accelerated motion, together with the notion that gravity is indistinguishable from acceleration. Turns out that the geometry gets even weirder when you try to describe the field of local "accelerations" equivalent to the gravitational field. Space is effectively curved.

Answer 2

SRT are based on two laws.
1) The First law of SRT - the speed of a quantum of light in vacuum has
a maximal magnitude (constant, absolute) of c=1.
2) The second law - no other particle can travel with the speed c = 1.
Hence, a quantum of light is a privileged particle and SRT
examines the behaviour of a quantum of light in the Vacuum. SRT solve the problem:
that will take place, if quantum of light will change the rectilinear movement c=1.
He can change the rectilinear movement c=1 only on rotary movement.
And then these changes are described by the Lorentz transformations.
The circle turns to a sphere. And he works as electron .
And in this item electron is connected to electrodynamics of Maxwell.
In Maxwell's theory, the electron is considered local,
as though the particle is "at rest".
This means that it particle does not move rectilinearly,
but rotates around the diameter (has the form of a sphere).
The rotation of the electron creates electrical waves.
And then at the beginning of the last century many scientists
(Einstein, Lorentz, Fitzgerald, Poincare, Abraham) were interested in the question:
What will take place, if the electron (Maxwell's) begins to move - rectilinearly?
All of them came to the conclusion that there would be radical changes with the electron.
These changes are described by the Lorentz transformations.

Answer 3

It's hard to get a good explanation without that "higher physics" talk.

Einstein is famous for his theories of relativity. There's the "special theory of relativity" and the "general theory of relativity".

The special one is about objects that are moving relative to one another, but that are not changing speeds. In this theory, einstein shows that nothing moves faster than the speed of light - but moreover, he shows that the speed of light is the same for all observers, no matter how fast they're moving. This happens because when you're moving, space and time change. The faster you go, the slower time goes, and the more compressed space becomes.

The general theory is about gravity; it's where einstein explains where gravity comes from. He showed that gravity happens because objects with mass cause spacetime to warp, and he also showed that acceleration due to gravity is the same as any other type of acceleration. I know, higher physics talk, but that's the simplest way i can putting it without going into a long, long diatribe.

Answer 4

Despite what the 'experts' here tell you, Einsteins theory is NOT E=mc^2.
There are two theories of relativity: the Special and the General. The special theory deals with bodies that are moving with constant relative velocity. The general theory covers bodies moving with constant acceleration.

Essentially, Einstein developed his ideas from two fundamental precepts: (1) that electro-magnetic radiation (light) is the limiting speed in the universe, and (2) the laws of physics must be the same to any experimenter - no matter how fast he is moving.

The consequences of the theories are, of course, much too extensive to be dealt with here.

Answer 5

You know that light can travel 3 lacs km in one second. Einstein stated that E=m x ( 3 lacs x 3 lacs), where m is mass of object and E is energy produced, meaning that 1 kg of Coal is sufficient to produce the energy, which can boil tonns of gallons of water but the condition is that there must not be any smoke, ash etc. coming out of the burning of coal.

Answer 6

Immagine 2 of your freinds (Bart and Lisa Simson...) are on a long bus going at 100 km/h. You are standing on the side of the road to see the bus go by.
When the bus passes by the point where you are standing.
Bart is running from the back of the bus to the front at 5 km/h. Now Lisa is running from the front of the bus to the back of the bus at 5 km/h.

Youare standing and looking at the bus that is still going at 100km/h
Your speed is 0km/h, compared to the bus,
Bart is going at 105 km/h compared to your speed.
And lisa is going at 95km/h compared to your speed.

Answer 7

RELATIVITY.
If u spend 5 min with ur close & lovable friend on a interesting tophic,
or u spent 5 min by sitting on a very hot pan,
u will feel that 1st 5 min spent was spent quickly rather than the
2nd one. I hope u understand.

Answer 8

hi im 15 so yuor probaly in 9th grade he basically said time travel is not possible "an infinite speed needs an infinite energy source"

the equation E=mc2

means energy equals mass squared you asked for a 14 year old answer and you just got one hope your happy

Answer 9

Einstein's theory is E=MC2
Energy = (Mass)(Speed of light in centimeters)2

Answer 10

SINCE U R 14

"WE" have Search the Web for THAT

Good Luck
