- Special relativity revealed that the speed of light is a limit that can be approached but not reached by any material object. It is the origin of the most famous equation in science, E = mc2, which expresses the fact that mass and energy are the same physical entity and can be changed into each other.

6 days ago · The derivation of special relativity depends not only on these two explicit postulates, but also on several tacit assumptions (made in almost all theories of physics), including the isotropy and homogeneity of space and the independence of measuring rods and clocks from their past history.

6 days ago · As it turns out, special relativity is crucial to explaining the correct chemical activity of the elements predicted by chemistry, the behavior of magnetic materials, and the behavior of subatomic particles in particle accelerators, all of which involve particles such as electrons or protons moving at relativistic speeds.
2 days ago · The fact that Special Relativity had to be improved towards General Relativity is essentially due to two main reasons: From one side, Einstein, according to the Mach criticisms [21], realized that the laws of Physics must be written in the same way for any (inertial or non-inertial) observer (Invariance Principle ). Secondly, considering the ...
3 days ago · In this new edition, a wide discussion on metric-affine theories of gravity and equivalent formulations of General Relativity is reported. The aim is presenting also topics which could be useful for PhD students and researchers studying General Relativity from an advanced point of view.
1 day ago · Special relativity is defined in the absence of gravity. For practical applications, it is a suitable model whenever gravity can be neglected. Bringing gravity into play, and assuming the universality of free fall motion, an analogous reasoning as in the previous section applies: there are no global inertial frames. Instead there are ...
Apr 29, 2024 · Special relativity, formulated in 1905, asserts that the speed of light is constant and the same for all observers, regardless of their motion. It also shows that time and length can appear different depending on an observer’s relative speed.
