Time Travel, Space Travel, Speed The Earths Movement, Speed Of Light

  1. Apr 28, 2013 #1
    I'm not sure if this is the right area of the forums.
    If it's not. Tell me which area would be better and I'll post this there.

    Time Travel-

    Would have to be space travel... and possibly faster than light
    If the time traveled and the time it takes to travel took less time to travel than it would
    take light to travel the same distance.

    you are at point 1.2x, 3.6y, and 128z

    2 seconds later you are at point 1.3 x 3.8 y and maybe 128z

    If you wanted to travel back in time you would also have to transverse

    If you went back in time to your current location you would most likely end up in
    the middle of outer space.

    Space Travel-

    How fast are you/anything that moves actually moving?

    How fast do,are,can space crafts move?

    How fast is the universe moving?

    How fast are we moving in the universe?

    Speed Of The Earths Movement-

    Speed Of Light
    299 792.458 kilometers / second

    If a light source is in front of you and you are moving in the universe towards
    the light then you should reach the light faster.
    As fast as you are moving in the universe towards it.

    The same would be true if you are moving away from the light source.
    The light would have to travel however much farther to reach you.

    How fast are we moving in the universe?

    100 kilometers / second----100,000 kilometers / second???

    If the speed of light is a constant, by by placing 1 satellite that rotates around the sun
    you would able to find out exactly how fast we are moving in the universe.

    Earths Orbit= x plane.
    Satellites path = y plane

    All that would have to be done is measure from the earth and the satellite the changes in the time light takes to travel to them.

    This could also be tested on a smaller scale if the equipment to measure accurately enough was

    We could find the direction of movement and the speed.

    Has this been done?

    (If this is done or has been done and the speed light travels ends up being the same regardless of orientation to the light source, but only dependent on distance.)

    (What does that imply ?)

    Speed Of Light-

    Is the known speed of light only the known speed of light inside of
    the gravitational field of the sun?
    The galaxy?
    The universe?

    Is the speed of light the max speed light can move in the suns field?
    A galactic field?
    a universal field?

    Does the speed of light change outside of, the earths field? the suns field? the galaxy?


    Does an object in the space inside the solar system
    if given an initial velocity loose or have it's relative velocity
    to the earth change from the movement of the solar system/galaxy/universe?

    Space as we have seen it is possibly not the same as space outside of the suns field.

    Could space inside of an identical suns field in another galaxy have completely different properties.

    Is there a global field, solar field, a galactic field? a universal field?

    Do the fields act as limiters.

    Less of a limit outside of the earths field, less outside of the suns field, less between galaxies?

    I think you put too many questions in your post with each requiring a lot of explanation.

    Where did these questions arise? Are you studying physics or reading a book on it?

    There are some people on here smart enough to answer your questions, but you probably need to break them up and judiciously space them out over a number of threads.

    I agree. Please focus your inquiry to the one or two most important questions.
