Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels.Nov 7, 2017

Length contraction is the phenomenon that a moving object's length is measured to be shorter than its proper length, which is the length as measured in the object's own rest frame.

History · Basis in relativity · Reality of length contraction · Derivation
A clock in a moving frame will be seen to be running slow, or "dilated" according to the Lorentz transformation. The time will always be shortest as measured in its rest frame. The time measured in the frame in which the clock is at rest is called the "proper time".
What is the Lorentz contraction?
One of the peculiar aspects of Einstein's theory of special relativity is that the length of objects moving at relativistic speeds undergoes a contraction
along the dimension of motion. An observer at rest (relative to the
moving object) would observe the moving object to be shorter in length.

How does gravity affect space and time?
Gravitational time dilation. ... The higher the gravitational potential (the farther the clock is from the source of gravitation), the faster time
passes. Albert Einstein originally predicted this effect in his theory
of relativity and it has since been confirmed by tests of general
relativity.
Which is proper time?
In relativity, proper time along a timelike world line is defined as the time as measured by a clock following that line. It is thus independent of coordinates, and a Lorentz scalar. The proper time interval between two events on a world line is the change in proper time.

The term mass in special relativity usually refers to the rest mass of the object, which is the Newtonian mass as measured by an observer moving along with the object. The invariant mass is another name for the rest mass of single particles. The more general invariant mass (calculated with a more complicated formula) ...

https://en.wikipedia.org/wiki/TensorJump to Definition - In mathematics, tensors are geometric objects that describe
linear relations between geometric vectors, scalars, and other tensors. ...
A vector is represented as a 1-dimensional array in a basis, and is a 1st-order tensor.
Scalars are single numbers and are thus 0th-order tensors.
