Renato Iraldi's latest activity

These are conceptions of the universe and there are no experimental demonstrations that allow us to reject one in favor of the other...

from another point of view: the cause and effect chain, time dilation is not the cause and it is not an effect either. When we say that...

You're right, I was confused. What I mean is that if a car has kinetic energy. I get on a train and go at a higher speed, it is not real...

My idea is difficult to express, what I think is that the measurement of a property that is real cannot be modified by the presence of a...

We don't have a definition of what real means, so I'll give a definition and then discuss whether time dilation is a real phenomenon or...

That is a bad way to state it because you are not looking at how fast one clock is ticking. You are looking at a series of moving clocks...

this is why i say "it seem to go faster"

I think it should be specified what it means that one clock runs slower than another. The Lorentz transformation gives us t' =t*gamma...

To reason with time dilation we must take into account that in relativity you can only compare clocks that are in the same place, you...

They don’t agree on “now”. That is what the relativity of simultaneity means. In the Lorentz transform $$t’= \gamma(t-vx/c^2)$$ So...

Yes tottaly true. But is the paradox thath show the need to use relativistic hooke law. nnnn b surely you can prove that it is the...

I apologize, I am 82 years old and I had not seen Epstein's diagrams until recently, and people tend to think that ignorance itself can...

You are right if it accelerates equally and simultaneously in the ground system, it does not mean that it accelerates equally and...

You don't like Epstein's diagrams because you haven't studied them, but I'm sure that if you study them you will appreciate them a lot...
