If Space eventts observed at 2 different times cant be the same,what is the relativity observed?

Answer 1

Special relativity says that for any two events, the space separation squared, minus the time separation squared, is constant for all observers.

Space separation in meters, time separation in seconds multiplied by speed of light.

s^2 - (t*c)^2 = constant

Answer 2

I'm guessing that your question is, "If two observers witness the same event in space at two different times, is this an effect of Relativity?"

Not necessarily. If one observer is 5 light years away from an event like a supernova, and another observer is 6 light years away, the second observer will see the supernova 1 year later than the first. This is simply due to the amount of time it takes the light to travel to each observer.

Answer 3

I don't truly understand what you are asking. I read this question in two ways. Below are the answers for the two possible ways of reading it.

1. The answer depends on the location of the observer relative to the location and time of the event in question. This is in reference to what Einstein referred to as the "observation effect." Another way of putting this paradox is Schrödinger's cat. In this paradox, Schrödinger's cat is alive nor dead, until observed. (see Wikipedia reference)

2. The other way of reading this is by stating that two of the same cannot occur and be observed at the same time. In this case, you would be talking about Pauli's principle (i.e. Pauli's Exclusion Principle) where, no two same objects can occupy the same space at the same time. (see Wikipedia reference)

Answer 4

I'm not entirely sure what you're asking here, but I'll give it a shot anyway.

One of the side-effects of relativity is the fact that there is no such thing as simultaneity. There's no way to find out if two event actually did occur at the same time due to time lag, i.e., it takes time to send data.

An event observed at two different times can be the same event, but it takes a bit of doing. It depends on what you mean by "different times" and what frame of reference you're using.

I hope this was at least moderately helpful.

Answer 5

Ah goring, your questions are so semi-coherent!

Suppose two events in spacetime, as observed by one observer, are at the same place, but separated in time, like two flashes of the same strobe lamp. Another observer, moving with respect to the first, will see these two events as separated in space as well as in time.

Answer 6

The relationship between 'cause' and 'effect' has to be maintained, so the relative 'displacement' between them must be either temporal or spatial.

Still haven't signed up for that Special Relativity course?

Answer 7

What is the relativity? What does that mean? Do you mean a calculation of some kind?

Answer 8

doug_donaghue is right. Its either temporal or spacial. Most likely spacial.
