special relativity - What do spacelike, timelike and lightlike ...
Mar 11, 2015 · Space-like is a hypothetical spacetime where causality is dictated by faster than light FTL speed limit and when projected in our time-like or light-like spacetime this could even resemble to …
What is the connection between special and general relativity?
Nov 14, 2017 · Special relativity, while excellent at handling accelration, has no gravity in it. The equivalence principle (s) says that locally, gravitation behaves like an accelrated system. If you put …
general relativity - Space is stretching. Is time also "stretching ...
May 25, 2025 · That aside: General Relatively says that time is inexorably linked with space (they bend alongside each other). Is time also affected by/similarly to the expanding of the fabric of space? Is …
general relativity - How exactly does curved space-time describe the ...
So much for the explanation of how curved space-time (discussion above was just about space; if you introduce special relativity into the picture, you'll get also new effects of mixing of space and time as …
general relativity - How can space time be bent? - Physics Stack …
Oct 1, 2021 · In special relativity the metric is constant and diagonal. In general relativity the metric is not, and this is what we mean when we say spacetime is curved. How can both of them be true at …
According to General Relativity, Does The Past "Exist"?
So the answer to your question is no. General relativity treats time as a dimension like space (though with a different metric sign). This just means that observers with different speeds get different 3 …
special relativity - On the philosophy of spacetime transformations ...
Jan 28, 2025 · In the physics we've studied upto and including special relativity, space and time are considered real physical objects each, and something like length contraction and time dilation were …
Why does everyone say that the faster you move through space, the ...
Nov 2, 2021 · People who say "the faster you move through space, the slower you move through time" have it the wrong way around. It's really "the faster you move through space, the faster you move …
general relativity - Gravitation is not force? - Physics Stack Exchange
In General Relativity trajectories of free falling particles are then geodesics (free motions) in the courved space generated by the mass M. In General Relativity there is no need for a gravitational force …
general relativity - Can anyone explain me how time can bend …
Jul 2, 2015 · General Relativity Einstein then went a step further. He realised that considering time and space together as spacetime allowed him to think about gravity. Einstein imagined spacetime being …
