It arrives at both embarcation and destination points simultaneously, but is red-shifted at the embarcation point and blue-shifted at the destination point. The speed of light is constant relative to any Observer, even one traveling at half the speed of light. Spacetime itself "bends" from the point of view of the Observer to maintain that maximum speed. So while the Observer is traveling at 50% of the speed of light, the Embarcation point and the Destination point appear closer to the Observer, and closer to each other. The entire Universe appears to "flatten" slightly, because Spacetime is not rigid, it's somewhat plastic. It "warps" around mass, for example, creating the effect we call "gravity."
Man I need to smoke a joint then re-read that.
The really fucked-up part is that the flattening effect only affects the Observer, so the distances between objects in the Universe is never absolute, and always depends on relative velocity. But the Universe isn't REALLY flattening and expanding, it's just that Space and Time are two facets of the same thing, which we call Spacetime, and so since the distances can't "REALLY" be that variable, what happens is that Time moves at a different pace. You see, velocity is a rate of distance (Space) over Time. So Time simply lengthens and foreshortens to every Observer based on his relative velocity to any given object. Mathematically, that's the exact same thing as the DISTANCE changing, since the velocity is the only true variable in the equation.
Shit, now I need some pot too!
Trust me, you still won't understand but now you know it doesn't matter since it's a make believe scenario so no fucks given whether you understood it or not it still doesn't matter and you're high now so it's OK with you.
What he said. Think of a football field. If you are massive enough, then the yardage lines bend to you. When you slow down the lines snap back and you are there in less time then your speed would merit.
see i would have gone with it will never reach either...
I was just about to say this same thing.
If spacetime is dependent on speed and gravity then every location in space has a different speed of time, and a different local ruler. This contradicts the fundamental tenant of science which is that physics is the same everywhere.
Physics is not the same everywhere, that's a canard. There are different rules of physics in, say, the flat near-vacuum of intergalactic space, at the event horizon of a black hole, in the millimeter-deep "atmosphere" of a pulsar, in the quark soup generated by the Large Hadron Collider, and so forth.
I've heard it said that the closer (your ship in this example) approaches the speed of light, the greater its mass becomes and at the speed of light, your ship reaches infinite mass. How can that possibly be?
Well that just says that since it takes infinite energy to move infinite mass, then moving ANY mass to the speed of light is impossible. It's like dividing by zero, it's just plain not a thing. Actual impossibilities are rare, so relish this one.
I've seen that error shut down my programs before. "Division by 0. Process terminated." That bothers me. Division by zero should result in the original number. (1+1=2... 1-1=0... 1x1=1... 1/0=1) If you have 1 and divide it by nothing, shouldn't you still have 1?
That's the point. An object can't reach infinite mass, thus an object with mass can't travel at the speed of light. Only electromagnetic radiation can do that.
