Aliens

Actual, physical aliens could not have visited us! Because even technology that could theoretically make spacecraft astonishingly fast could not help them get here. In fact, the faster they could go, the more quickly catastrophic disaster would destroy their craft.

Yes that is addressed in the movie, I don't remember the exact quote but it was something along the lines of - if you were travelling at 25% the speed of light and your craft/shield collided with a golf ball size piece of debris it would create an explosion the equivalent of 8 atomic bombs going off at once. And we know how much space debris is out there

But then again, if an alien civilization had the scientific knowledge to travel at impulse speed, it would not surprise me a bit to know they might also have the technology to avoid or destroy anything in their path. After all, what is the point of inventing an unusable (even untestable) travel mode?

And yes, only trekkies (or pretty much anyone with access to google ) know that impulse speed is a quarter light speed.

Or they can use worm holes and avoid travelling at high speed.

Hana: Or they can use worm holes and avoid traveling at high speed.

There is no current scientific evidence that wormholes would make a faster route of travel.

Below is what Hugh Ross of Reasons.org has written about it:

Loopholes Via Wormholes? (This is an outtake from this article: https://www.reasons.org/explore/public ... from-there)

Highly imaginative and technically trained UFO and ETI buffs suggest that advanced aliens may have found a way to use space-time “wormholes” to travel to distant locations in the universe in a relatively short time. On closer examination, however, this idea offers no help at all in solving the distance and time problems.

General relativity says that massive objects distort the curvature of space and time in their vicinity. The greater the mass-density of an object, the greater the degree of space-time curvature it produces in its immediate vicinity. General relativity predicts that when matter becomes sufficiently compressed by its own gravity (as in a black hole), a discrete region of space-time will develop where the curvature becomes infinitely sharp (Figure 1). That is, a singularity (region where the mass density and space curvature become infinite) will develop at the center of the mass concentration.

If a black hole connected to one sheet of space-time in the universe happens to make contact with another black hole connected to a different sheet of space-time, that point of contact may (hypothetically) offer a travel corridor. The point of contact, however, must be singularity to singularity (Figure 2) so that a traveler funneling into the center of one black hole can come into contact with the center of another black hole.

While these so-called wormholes connecting one black hole to another black hole are mathematically possible, one must question the physical practicality (not to mention plausibility) of their use by alien travelers. According to the best-established models for the universe, regions of space that could be connected via wormholes are already close to one another. In other words, the use of a wormhole would offer little time advantage. One cosmic model in which a ten-dimensional space-time sheet bends to make a U (Figure 3) offers the possibility of a significant shortcut through space, but ongoing research has yet to verify the viability of such a model.

And in this video, Hugh Ross expounds further about the impossibility that REAL aliens have been visiting earth: https://www.youtube.com/watch?v=2aITwrnl-V0
