## Main Question or Discussion Point

Hi everyone!

I am new here. I like physics and so I am trying to understand a few things. I think I understood the newton physics. Now I am reading about relativity.

I began wiht special relativity. I just learn the two postulates. I think I can accept them with out problems. I also read about the simultaneity issue. But before I proced I would like to be sure that I anderstood what I have learned so far. So I will try to post a litle question to see if someone can help me on this... Sory about my english... Ok, lets go!

Let's supose the following situation:

There is a rectilinear path A-B-C where B is half way from A to C. An observer is on his way from A to C at velocity "V". At the exact time when he passes through position B, two gun shots are fired. One from A and the other from C. Both in B direction. The shotguns also emited a flash of light at the time of the shots. So both bullets and light beams are on their way to position B.

I belieave I have learned so far that the observer in movement from A to C will first see the light from C than the one from A, and then will take the shot from bullet comming from C also first than the one comming from A.

Is this correct?

If so, then I have to conclude that there is no diference in the behavior of the light and the bullet.

But from the postulates of special relativity, I understood that light travels always at "c" from the point of view of any observer, independently of his velocity. So, will it be supid to say that the observer from my experiment should see both light beams at the same time??

If not, than for me the light behaves just as a simple bullet...

Can someone write a few words about this please?

But please go easy on me, because I am a slow learner...

Thank you all!
