10 hours ago · In the general theory of relativity, energy conservation didn’t appear as a natural consequence that was “baked into” the fabric of spacetime itself, but rather only appeared as an identity ...

4 days ago · One of the central ideas of General Relativity is the principle of equivalence, which states that the effects of gravity are indistinguishable from the effects of acceleration. Another key concept is the idea of spacetime curvature, which describes how mass and energy warp the fabric of spacetime, causing objects to follow curved paths through ...

2 days ago · Linear dynamics and classical tests of the gravitational quantum field theory. We explore the new physics phenomena of gravidynamics governed by the inhomogeneous spin gauge symmetry based on the gravitational quantum field theory. Such a gravidynamics enables us to derive the generalized Einstein equation and an equation beyond it.
2 days ago · Evolution of the Big Bang Theory. The history of the Big Bang Theory can be traced back to several key developments in theoretical physics. Einstein's General Theory of Relativity (1915): Einstein's theory provided a foundation for understanding the behaviour of space and time, which would later be applied to the development of the Big Bang Theory.

Which are reference frames in which Newton's first law is valid: if an object experiences no net force, the object either remains at rest or continuous in motion with constant speed in a straight line.
