How Does Relativity Affect Our Perception of Light and Time?

Click For Summary
Traveling close to the speed of light affects the perception of light and time due to time dilation and the relativity of simultaneity. An observer moving at such speeds perceives light approaching at 186,000 miles per second, regardless of direction, because their own clocks run normally to them. However, from an outside observer's perspective, the moving observer's time appears to slow down. The discussion highlights that while light from both directions seems to arrive at the same speed for the moving observer, the perception of time and simultaneity differs between observers. This complexity illustrates the fundamental principles of relativity in understanding light and time.

[SOLVED] light and time

ok from what i understand if I am traveling just under the speed of light and looking foward the the light is aproching me at 186000 mps... there's 2 unites of measure here distance and time.. from what i know my time slows.. so the light seems to be reaching me at the speed of light instead of allmost double the speed of light... here's where my thought experiments come in.. if i turn around and look back in the direction I am coming from and time for me is still slow it should seem that light would be reaching me at 1/4 the speed of light. i know this not to be true... but it seems that if I am looking behind me at close to the speed of light my time would have to speed up to compensate and make me and any insterments percieve that the speed of light is still 186000miles per second

Only to the observer who sees you moving at that high speed will your clocks run slowly. As far as you are concerned, your clocks run just as they always do.
 
neither time dilation nor length contraction can explain why both the light coming at you head-on and the light coming from behind both appear to you to be moving at the same speed. that is where loss of simultaneity comes in.

ok i realize that to me everything is normal and and my clocks runing to an observer explaines y light coming at me from in front still seems to come at me at 186000 mp(s) cause (s) seconds are slower for me... however if i look backwords light will need to be coming at me at 186000mps... however won't my clock observed from someone watching me have to be running faster for this to happen..
 
ok thanks granpa .. i will look into this... not a bad question for someone who gets their knowledge from sci channel
 

Thread 'EPR revisited'

In an inertial frame of reference (IFR), there are two fixed points, A and B, which share an entangled state $$ \frac{1}{\sqrt{2}}(|0>_A|1>_B+|1>_A|0>_B) $$ At point A, a measurement is made. The state then collapses to $$ |a>_A|b>_B, \{a,b\}=\{0,1\} $$ We assume that A has the state ##|a>_A## and B has ##|b>_B## simultaneously, i.e., when their synchronized clocks both read time T However, in other inertial frames, due to the relativity of simultaneity, the moment when B has ##|b>_B##...
