How much time passes relative to the protons inside the LHC?
The time depends on the speed of movement. Protons in the LHC move at near-light speed. Therefore, they perceive a different time than the scientist who is observing them. My question is how much time ...

Does special relativity imply that there's such a thing as absolute time, or base time?
If time measured by one observer moving at a greater velocity than another observer is observed to be passing more slowly, does this imply that there's such a thing as "absolute time" or &...

What is the reason of different clock's measurements in different frames? [closed]
I tried to understand what is the reason of different clock's measurements in different frames.
For this I looked at easy example with distance S traveled by man with moving clock (velocity V1=2m/s) ...

How to prove that time slow down on all type of clocks? [duplicate]
I read about time dilation and how to prove time dilation existence with light clock.
But how to prove that time slow down on all other type of clocks (biological, mechanical, digital, electric, ...

Time dilation and understanding which is $\Delta t$ and which is proper time $\tau$
In the textbook that we are using, the definition for proper time $\tau$ is the interval between two events, as measured by an observer who is at rest with the two events. The definition for $\Delta t$...

Relativity theory inconsistency
Suppose I have two synced clocks, light-based for simplicity (light bouncing between mirrors up and down).
A train comes by me at some velocity u and I put one of the clocks on the moving train.
...

Special Relativity and Hypersurface of Simultaneity?
In Special Relativity when I move backwards and forwards my hypersurface of simultaneity moves too.
Does time really oscillate backwards and forwards as I move around? Or is it just the application of ...

Temporal Ordering in Special Relativity [duplicate]
Not a physicist: but want to use the temporal ordering of events in special relativity as an example for something, and need to answer the following question to do so.
Suppose we have three events, a, ...

Is Newton's laws formulated using laboratory time?
The second Newton's law can be written as (in SI units)
$$
\frac{d}{dt}\vec p = \vec F.
$$
Newton was considered Galilean transformations and the existence of a "absolute" time. Now suppose ...

How can we have motion through time with Relativity? [closed]
How can anything actually move through time if Relativity is correct? It seems everything is just a Lorentz Transformation to a different reference frame and 4D spacetime keeps track of all of these ...

Simultaneous events [closed]
It follows from relativity that "simultaneous events" cannot happen in our universe. If $A$ and $B$ are two events which happen at the same time in reference frame $F$, we can find reference ...

Why light travel along with light clock? [duplicate]
I am interested in exploring time dilation effects. I came across a video and I learned that when we move a light clock in constant velocity the light bounce will take a longer time with more speed. ...

Twins Paradox: Back on Earth, same moment? (and always) [closed]
Supposing twin A, having been on a well-known circular near-light-speed journey, returns to Earth a younger man than twin B.
Let's say A took off at 3pm and upon return has aged 2 hours while B has ...
