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.
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...
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...
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 *...
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.
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...
