I was laying in bed and a thought came to me. Im sure this has been explored already so I wanted to know what the answer was as my physics is limited as I study biochemistry. I have a feeling this is related closely to general relativity, but again maybe someone could clear this up for me... thanks Ok, so its clear there are no fixed referance points in the universe, as in... movement is a meaningless concept unless related to another object. hopefully makes sense. I came to this conclusion because GPS satellites work by timing the time a radio wave bounces off the earth, so if we were 'moving' the speed of light would be different depending on what direction you was headed.... but of course 'direction' again is a meaningless concept. I did google this and it seems this is a consensus. So, there must be a point on the otherside of the universe (for example) where the stars are moving at faster the speed of light (in relation to the earth) perhaps across our path,,,, but so far away we may not even be able to detect it. I think this is a reasonbbale conclusion? So...... doesnt this mean that faster than light travel is possible.. because speed is a completely meaningless concept? right? So in theory (ignoring the fuel needs, and maybe fear of banging into objects floating around in the solar system) why cant we just get in a rocket, hit the accelerators and the speed will just increase theoretically into infinity (in relation to the earth of course). There is no limit to the speed we can reach because again.. speed is meaningless. I am aware that apparently nothing can travel faster than light, but how does this fact take into account what Im saying (that speed is meaningless as there are no referance points to go from) Im fascinated to know if this idea has been tested, and if there is any experimental evidence suppotying/disproving this idea. Thank you.
