Ok, I figured it out myself. The answer is that the car does not see the two beams of light reach his car and the same place and time. He sees them reach his car at t=4 and x=0 and t=16 and x=0 but the key to the answer which I overlooked was that unlike the observer the car does not see the...

Ok then how do you explain the original situation "If you are standing at the side of a road and you see a car going at 0.6c and 8 light seconds down the road in both directions someone is shining a flashlight toward the car. From the car's point of view the two beams of light should reach...

Yeah, but... If two events have the exact same co-ordinates in one frame of reference, how can you use the Lorentz transformations to find two different sets of co-ordinates in another frame of reference?

Yes, How can two events happen at the same place and time in one frame of reference and not in another? If two events have the exact same co-ordinates, how can you use the Lorentz transformations to find two different sets of co-ordinates in another frame of reference?

How can two events happening at the same time and place in one frame of reference happen at a different time and place in another frame of reference? For example: If you are standing at the side of a road and you see a car going at 0.6c and 8 light seconds down the road in both directions...

Ok well what would it look like if you used the lorentz transformations to solve the problem? (I keep getting intead of t = 8 and t = 8 I get t = 4 and t = 16) and what about question 3?

three questions: 1 if you are standing at the side of a road and you see a car going at 0.6c and 8 light seconds down the road in both directions someone is shining a flashlight toward the car, then without time dilation or contraction or anything the car would see the a beam of light...

So in the body's frame of reference does the space in front of it shrink and the space behind it grow?

sound waves travel through air; waves on the sea travel through water; what do light waves travel through?

If a body's time must slow down when it moves in order for the speed of light to remain constant then how can the speed of light remain constant if two waves of light are moving toward the body from two different directions? Say the body has two light particles coming towards it. Particle A...
