Questions about physics

I think the thing thats hard to grasp is you don't change at all, the universe changes around you. Even electric fields start to turn into magnetic fields. On top of that, if you imagine going the speed of light and then someone starts chasing you, are you still going the speed of light once they've made a little progress? To them you wouldn't be or would you? And then you go right into a black hole only you find that it's a long way to the center once you think you are already there.

thats the problem with the observer model. you create bizzare problems that simply don't exist.

Special Relativity has a very real effect on subatomic particles. Take for instance the muon, it has a lifetime defined while it's at rest. i.e. If you have a muon 'sitting' on you bench, it will decay after x amount of time.

Now, if you take that same muon and have it hurtle through the Earth's atmosphere at some large fraction of the speed of light its lifetime will be significantly increased and indeed matches the predictions made by SR. It is not simply "appearing" to live longer...it actually lives longer.

This is not specific to muons, find me an example of SR being violated and then you can argue about its validity.

exactly how did a moun ever become a measured anything ? its a energy signature from a particle accelrator, atmoic trash if you will.

SR is invalid, but some tennents of it bear fruit.

What parts of it are invalid, because much of it is used, and proven on a daily basis.
