Absolute, true and mathematical time, of itself, and from its own nature flows equably without regard to anything external, and by another name is called duration: relative, apparent and common time, is some sensible and external (whether accurate or unequable) measure of duration by the means of motion, which is commonly used instead of true time ...https://en.wikipedia.org/wiki/Absolute_time_and_space
So this got me to thinking, suppose we were really into space travel, suppose our super fancy atomic clock that was set back on Earth to the relative time there, and our super fancy clock broke. Uh Oh, how can we know where earth will be at any moment in time?
Some things that I think need to be overcome to determine an "absolute" time:
- Mapping trajectories of ALL universes
- Planet/stars etc.
I think if you have those two things we could then say that if a particular planet we were nearby is in a particular location with respect to another say 2-3 planets/universes, we could then triangulate where we were with respect to the rest of space. Unfortunately I just don't see a way of getting around using "relative" positions in space to determine absolute time.
One thought I had was suppose we took a radioactive item, encased it so it was safe for human use, and then we setup a monitor, and on day 1 it read the decay and we initialized the value, then as we move through space we have a pretty accurate clock, that isn't dependent on factors such as magnetism, or other things, the problem goes back to "what if it breaks", how can we get back?
Taking off from somewhere in deep space and "hoping" that a planet isn't in your way when you take your straight line path is going to be problematic.This is why we need an absolute time calculator. With that you can create a "FMS" of sorts for space that will calculate positions of planets in your trajectory, as well as different gravitational pulls as you move through space. (in Theory)
Some of the upcoming posts are a bit inspired by Elon Musk's big ideas, If you don't know who he is take a look at his wikipedia page, I think some of the goals he has are amazing, and I agree that we as a society need to start focusing our efforts on big ideas, and not on the next fart app. A collegue and I have been chatting about space travel and how amazing it would be to make it to Mars, so we started looking into it, I don't know much of anything about it, but who knows, maybe I'll learn something, and maybe you will too.Either way, knowing more about a wider range of technologies makes us better as a human race, fart apps, don't.
