Must energy always be conserved?
Matter and energy are always converted due to the theory of relativity.
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.
If new evidence was found in the theory of relativity can it be updated?
Of course. As it is we already know both relativity and quantum theory must be updated to make them unify, we just don't know how yet.
How is Einsteins theory of relativity used in modern maths?
I think the question must be the other way round!
What conditions must be satisfied for momentum to be conserved in a system?
For momentum to be conserved in a system it must
When did Einstein prove the theory of Relativity?
In November of 1919, at the age of 40, Albert Einstein became an overnight celebrity, thanks to a solar eclipse. An experiment had confirmed that light rays from distant stars were deflected by the gravity of the sun in just the amount he had predicted in his 1916 paper on his theory of gravity, general relativity. General relativity was the first major new theory of gravity since Isaac Newton's more than 250 years earlier.It has never been proven, and it never will be. However, there is a vast amount of evidence consistent with it, and so far nothing has contradicted it either. Einstein didn't prove the theory -- he just created it.The above paragraph is not entirely correct. There is the Gravity Probe B experiment which should provide some conclusive results regarding proving the theory in the near future. See the following links for more information:http://www.nasa.gov/mission_pages/gpb/index.htmlhttp://einstein.stanford.edu/highlights/status1.htmlhttp://en.wikipedia.org/wiki/Gravity_Probe_BThe atomic clock has proven his time dialation to be correct.
Where does a photon get its speed from?
Nowhere. A photon must travel at the speed of light so it starts with that speed when it is created. This is the origin of the theory of special relativity.
How is the Bing search engine better or worse than Google?
For example, if you wrote "What is Einstein's theory of relativity?"-Bing:Result 1:[Set of images]Theory of relativityThe theory of relativity usually encompasses two theories by Albert Einstein: special relativity and general relativity. Concepts introduced by the theories of relativity include spacetime as a unified entity of space and time, relativity of simultaneity, kinematic and gravitational time dilation, and length contraction. Result 2: Theory of relativity - Wikipedia-Google:Result 1: Einstein's Theory of General Relativity: A Simplified ExplanationResult 2: 2. Physics. a theory, formulated essentially by Albert Einstein, that all motion must be defined relative to a frame of reference and that space and time are relative, rather than absolute concepts: it consists of two principal parts.-Note: These are copied as-is on Jan 2018. Screenshots might have been better, but there is no option to upload images (a link would be nice...).------------------------------------------------------------OLD/Invalid Answer:Bing is much worse than Google, because if you type something specific in it comes up with results that are mostly nonsense and off-topic. For example, if you wrote "What is Einstein's theory of relativity?" The first result would be... "Get great discounts on Einsteins theory of relativity!" and the rest would be equally obnoxious.
Give the value of scientific theory?
A scientific theory must be based on many repeated correct experiments; also this theory must be related with other accepted theories.
Why must energy always be conserved?

Why couldn't Einstein accept that the universe was expanding?
Its not that he couldn't, he eventually did and declared his "cosmological constant" the biggest mistake in his life.The situation was when Einstein developed General Relativity the prevailing cosmological theory was the Steady State Theory, that the universe was static. However General Relativity predicted that the universe could NOT be static: it must be either expanding or contracting. To correct for this apparent "error" and conform to the prevailing theory, Einstein added an arbitrary fudge factor that he called the "cosmological constant" that could be tweaked as needed to keep the General Relativity predictions in accordance with the Steady State Theory.When it was clearly shown that Hubble's data was right and the universe was expanding, he willingly deleted the "cosmological constant" from Relativity.
What would be an example of a scientific theory?
any belief in science that is plausible and for the most part has some evidence, but we aren't sure of being 100% true, would be a theory. for example, the theory of relativity, darwin's theory of evolution, etc.
