That may be wrong, but here is the deal: We don't know what is possible and what isn't. 100 years ago, radio was just starting to make a splash. 200 years ago, telegraph had not been invented yet and if someone had suggested electric lights and radio, not to mention TV would be in homes across the nation people would have laughed their heads off. Jules Verne tapped into the fantasy of people and made several novels about impossible things that later became reality.
Who knows what is really possible. Anti-grav device? Possible, not known yet, but possible. Space time warp? Possible, not known how yet, but possible.
Never say never, never say that beings from other worlds couldn't be coming here, because we simply don't know. No evidence yet, but none that totally refutes the fact either.
Well said. You left out that someone only a hundred and fifty years ahead of our technology could be living underground on Mars or other moons around other planets in our own solar system, from whence they have arrive we know not, but they wouldn’t have to have ‘warp drive’ to be here in our neck of the woods, perhaps even evolved on a more hospitable Mars eons ago.
Indeed...
You hit on a personal bugaboo of mine, which you might enjoy as theory.
It is “Any time machine is likewise a ‘space’ machine”. Though even some golden age science fiction addressed this situation, I don’t believe it’s ever been used as a plot devise.
Simply put: right now, you are hurtling through space at tremendous speed. The Earth is turning, the Earth is orbiting the Sun, the solar system is spinning around the Milky Way galaxy, and the Milky Way galaxy is moving in the universe. Add them all together, and you are on a very high speed vector in some direction.
And where you are this very moment is a vast *distance* away from where you were just a second ago, and where you will be in one second. So if you get in a time machine, and go a few minutes into the past or the future, it is likely that your time machine is going to explode because of the instantaneous loss of external atmospheric pressure.
However, if you do have a spaceship/time machine, you can travel great distances very fast indeed, but only in two directions.
Yet, if you distinguish yourself from the future flight path of the Earth, say your time/space machine starts flying toward another star, and you jump into the future where you would *possibly* have continued to that star, would you travel at the same *speed* you were traveling when you went into the future, or would going into the future extrapolating your *acceleration* when you jumped into the future.
That is, while the speed of an F-16 is fast, the acceleration of a mosquito taking off is far greater than that of an F-16. So if your time travel was based on the speed you were going, say 1000 mph, it would be vastly slower than if it extrapolated the continuing acceleration of the mosquito. It would be faster than the speed of light in short order.
