    Understanding Lorentz Transformation & Time Travel at Light Speed

    Ibix, thanks for showing me what was breaking my math equations. I went back and I think I fixed it.

    Understanding Lorentz Transformation & Time Travel at Light Speed

    That last post came out really garbled. Can anybody tell me what I did wrong with my mathematical expression? I tried to say t prime equals gamma times (t minus the fraction of vx over c squared), but it looks like the third pound pound is not working.

    Understanding Lorentz Transformation & Time Travel at Light Speed

    Then in my example, the reference event would be the launch of the mentioned spaceship from planet Earth, bound for Kepler-452b. The value ##t## is the time as seen from Earth, while ##t'## is the time seen as astronauts on the space ship, and at the launch of the spaceship they are both set to...

    Understanding Lorentz Transformation & Time Travel at Light Speed

    By synchronized, do you mean that for the first reference point when the time ##t## equals the time ##t'## for the second reference point, the position for the first reference point also equals the position for the second reference point? Would it be erroneous to say that when ##t## equals zero...

    Understanding Lorentz Transformation & Time Travel at Light Speed

    So the x value in the mentioned box is the distance on the x-axis between the two references that are moving away from each other at velocity v?

    Understanding Lorentz Transformation & Time Travel at Light Speed

    The thing that confused me about the "https://en.wikipedia.org/wiki/Lorentz_transformation" website was the section labeled "Physical formulation of Lorentz boosts", subsection labeled "Coordinate transformation", the box labeled "Lorentz boost (x direction)" that has four lines: "t' = gamma *...

    Exploring Relativity in Science Fiction: A Software Engineer's Journey

    Hi, I'm Kevin Simonson. For most of my career I've been a software engineer; more recently I've taken an interest in writing science fiction, and that resulted in some questions I have about relativity, which resulted in me making a post to this forum.

    Understanding Lorentz Transformation & Time Travel at Light Speed

    Taking a look at "http://www.space.com/30026-earth-twin-kepler-452b-exoplanet-discovery.html" I observe that planet Kepler-452b (judged to be somewhat Earth-like) is 1400 light years from Earth. If a spaceship leaves Earth at a fifth of the speed of light, traveling toward Kepler-452b, from...
