What is the theory of relitivity?

The theory of relativity, proposed by Albert Einstein in the early 20th century, consists of two main parts: special relativity and general relativity. Special relativity deals with the relationship between space and time, showing that they are intertwined in a four-dimensional spacetime continuum. General relativity extends this to include the effects of gravity, explaining how massive objects curve spacetime and create the force of gravity. This theory has revolutionized our understanding of the universe and has been confirmed through numerous experimental observations.

What did albert einstein say about light?

Albert Einstein proposed that the speed of light is constant in a vacuum and that light can behave as both a particle and a wave, known as wave-particle duality. He also introduced the theory of relativity, which revolutionized our understanding of time, space, and gravity.

What can you say about the speed of the different colors light in air?

I could say that shorter wavelengths move faster, but that would be wrong. The truth is that all wavelengths/colors travel at the same speed.

How by moving at the speed of light you can travel in future?

Moving at the speed of light means traveling at a constant speed of approximately 299,792 kilometers per second. According to the theory of relativity, time dilation occurs as one approaches the speed of light, which means that time slows down relative to someone moving at a slower speed. This leads to the phenomenon where a person traveling at the speed of light would experience time differently than someone at rest, allowing them to potentially travel into the future.

If you can travel at velocity of light then what happens to time?

As a reference frame approaches the speed of light, time dilation occurs. From the perspective of an observer moving at a velocity close to the speed of light, time for a stationary observer would appear to slow down. This effect follows from Einstein's theory of relativity.

What is the speed of light per planet?

The speed of light is the same for every observer everywhere. That is a fundamental tenet of the theory of special relativity (and everything based on it, such as the general theory of relativity and quantum field theory). To date no violation of the consistency of the speed of light has been measured. By the way, this does not say the speed of light is the maximum speed, just that the speed of light is constant, so the possible discovery of faster-than-light neutrinos does not invalidate this.

What does the theory of special relativity say about the equivalence of different frames of reference?

It says that the speed of light in a vacuum measured in any inertial frame of reference is equivalent to the speed of light in a vacuum measured in any other inertial frame of reference.

What happens to an object when it moves at the speed of light?

According to Einstein's theory of relativity, an object with mass cannot reach the speed of light. As an object with mass approaches the speed of light, its mass increases infinitely and would require an infinite amount of energy to accelerate further. This phenomenon is described by the equation E=mc^2.

Is anything has more speed than speed of light?

no, according to Einstein with his theory on relativity. The speed of light is what a lot of scientist say is the speed limit of the cosmos. In particle accelerators they can accelerate small pieces of matter close to the light speed but can never reach it. If you were to travel until you hit light speed it would require all the energy in the whole universe or you could say it would take an infinite amount of energy to reach light speed. The only way around this is the Einstein-Rose bridge otherwise called a wormhole. This is a possibility according to Einsteins equations.

Why do people say faster than the speed of light?

"Beyond the speed of light" is often used as an expression to emphasize how fast something is moving. In reality, according to Einstein's theory of relativity, no known object can travel faster than the speed of light in a vacuum.

Is it possible for a human to move quicker than the speed of light therefor aging more quickly?

No, a human being cannot travel faster than the speed of light. In fact, according to the Special Theories of Relativity state that it would take an infinite amount of energy to accelerate to light speed, meaning that it is impossible for ANY particle to accelerate to light speed. As for the aging idea, this is just a bit of science fiction. However, the Special laws say nothing about particles constantly moving at light speed, which is where special particle called "tachyons" come into play. Finally, some hypothetical "transversal wormholes" may exists, where two points in space are directly connected, despite great distances, allowing theoretical motion much more quickly than light would take to travel the same distance normally, giving the effect of faster than light travel without ever actual exceeding the speed of light. Again, this is purely theoretical. Further more, the "speed of light" to which you refer is the speed of light in a vacuum. Having a particle actually move faster than light is possible when the light in question is traveling through a medium which slows it down, and not contradict the special laws.

Did Albert Einstein say it was possible to go to the speed of light?

No, Albert Einstein's theory of relativity states that as an object with mass approaches the speed of light, its energy requirement approaches infinity. This implies that it is not possible for an object with mass to travel at the speed of light.

What is the relationship between the velocity of propagation in a t.t.l and the speed of light?

The velocity of propagation in a TTL (transistor-transistor logic) circuit is typically much slower than the speed of light. In a TTL circuit, the signal propagates through electronic components, which causes delays that result in a lower propagation speed compared to the speed of light in vacuum.

What propels light to the speed of light?

Nothing propels it at all. It actually always goes that fast, even from its creation. To explain it to you mathematically would require the use of 4-D tensor products, so I won't bother with that here. Suffice it to say, that is one of the postulates of Einstein's general relativity. Light always travels at the same speed in any reference frame.

Based on the theory of relativity what must always be conserved?

It depends on which theory of relativity you mean. The special theory of relativity has only one assumption, namely that the speed of light is constant (in vacuum!) and has the same value for each non-accelerating observer. Thus you can say the speed of light must always be conserved. In the general theory of relativity (the one with the curved spacetime and the geometric picture of gravity), one further assumption is made; that the inertial mass (resistance to acceleration) of every object is equal to its gravitational mass (source of gravity). This is called the Equivalence Principle and is sometimes explained as the requirement that all things fall at the same rate (if there is no air resistance) regardlass of mass. In this theory the equivalance of the two types of mass is always to be conserved. Also note that although these are the main assumptions it is usually also assumed that energy and momentum are conserved and that there is no violation of causality.

What is the speed of light and the speed of magnetism?

so Im just going to straight up say use google but also I'm going to say the speed of sound is faster than the speed of light and magnetism is was slower.

Is speed of light and speed of sound different in different materials?

yesthe speed of light in a vacuum is different than the speed of light in our atmosphere or another planets atmospherethe speed of sound is also different in the air than when it goes through a solid or liquidAddional answerThe first answer above not quite correct. The speed of light is the same regardless of what it passes through. It's 186,282 miles per second, but there is a small change due to the refractive index of different materials. But this difference is much less than the difference of the speed of sound in different materialsIf we go even further, it's the same to all observers (as Einstein would say). That means that even if you were travelling at close to the speed of light, it would appear to be travelling past or towards you at the speed of light. Now we're into relativity!
