WolfishMusings-
I could be wrong on this, but I’m fairly certain you need to go faster than 25K MPH to see the effects of time dilation.
Unfortunately, I don’t remember where I saw it, but I recall reading that a small but measurable time difference did occur. B”N I’ll do a little research (google) later.
the speed at which you can measure the time difference is of course dependent on the sensitivity and accuracy of the time measuring device. You can measure the effect on a moving snail if you have a good enough device…80
Any technological advances that will allow FTL travel will probably not involve altering this law of physics, but rather with warping space and/or time in some way.
I’ve heard the term “worm hole” used with regards to this, similar to “tesseract” re: time travel, but who knows?
Bonus question: What was the first man-made object to move faster than the speed of sound?
1) The X-1 (level flight)
2) The P-38 (in a dive – this is where it was proven that an aircraft could withstand supersonic flight, although the controls froze, due to the shock wave, IIRC).
3) A bullet (no human aboard [except for in the book From the Earth to the Moon, speaking of books]).
4) A cracked whip’s tip (not the entire object, but a portion of it).
5) Anything man-made, since the Earth orbits at @66,000 mph, and rotates at @1,025 mph at the equator.
6) ?
