Relativity principle?the furthest an object moves away from you at high speed the smaller it appears?

Question

and if it moves relativistically towards you the bigger it gets from the frame of reference of the observer?

as the object move out at less the speed of light it looses mass and as it come back at the speed of light it gains mass and volume.So relativity depends on the observers frame of reference?

Answer 1

It appears smaller as it moves away due to optics (objects further from you appear smaller and closer ones appear bigger whether moving or not), not relativity. Relativity comes into play when a object isn't moving in the same reference as the observer.

As you approach the speed of light you would get thinner and more massive, but if someone is standing in your reference behind you, there would appear to be no change in size as long as the distance between the two of you doesn't change.

Answer 2

This is kind of interesting. The interesting aspect of it is how that mass directly converts into energy (kinetic) without a person being able to detect the transformation. This condition happens when you ride in your automobile or even walk. There is a continual increase and decrease of energy within your body that acts according to (hf=mk) - the kinetic energy of mass has as its basis Plank's constant times the frequency of the mass. As the frequency of light energy changes according to "hf" so, also, does mass, for mass is composed of electromagnetic energy.

How the transformation takes places is, that there is a conversion (decrease) of overall mass frequency (energy) at right angles to direction of travel that is proportionate to the increase of the forward frequency change.

The reason a moving mass becomes more compressed in direction of travel (appears shorter) is that the overall waveform increases in density = energy. This value exists within a mass no matter in what direction it travels.

I expect this seems kind of confusing, but it is the answer. You'll have to sort it out according to your desire to learn.

Answer 3

not exactly. No matter which way it is moving, as it approaches the speed of light, it gains mass. It is not relative, it is absolute.

Answer 4

The observer in motion , (NOT the one who is at rest) finds mass increased,length and time decreased in his frame of recerence ( moving reference frame).

Answer 5

yes
