You see, people like myself are always asked what makes me know aliens are here on earth. I have a multitude of answers for then, all very credible.
But when the tables are turned and I ask the question, "what on earth makes you think they are not here", then you will find that there is no
credible scientific fact thats says they are not or cannot be on earth.
Yes, there are credible scientific facts. One of them is that the laws of physics apply everywhere and to everyone in the Universe (hence "universal
laws of physics"). Inter-stellar and even more so Inter-galactic travel is as challenging to ETs as it is to us, no matter how advanced they are.
I also find it curious that not only have they overcome those laws of physics, but they also apparently come from a Planet with identical or nearly
identical properties as Earth. It must have the same mass and gravitational forces, the same atmospheric conditions and at least very similar food
sources. Why? Because all contact stories talk about Grays (or other entities) that apparently are very accustomed to Earths gravitation - they don't
float (as they would if their Planet's gravitational force would be stronger than ours) or have difficulty moving about (as they would if their
Planet had a weaker gravitational force than ours). They breath the same air, hence the chemical composition of the air on their Planet must be the
same as ours. The atmospheric pressure must be identical too, as they're not being crushed or blown up like a balloon by the atmospheric conditions
on Earth. I haven't seen or heard a description of Grays or another "alien race" needing a space suit to live on Earth. Strange.
"there is no law of physics preventing time travel", indeed, scientists have also come up with a multitude of diffrent models for faster than
Not sure where or why time travel comes in here but hey, it's your thread. Anyways, as a matter of fact, there are a myriad of problems with time
travel. i.e. You can't travel back in time farther than to the point where the time machine was invented. I don't know of a multitude of models for
traveling faster than the speed of light. I take it you talk about wormholes. Technically, an object traveling through a wormhole still isn't faster
than the speed of light, a photon entering the wormhole at the same time as your space ship, would still be faster than you (again, e=mc2 applies to
aliens too), it just takes a short cut through time/space, therefore bridges a distance faster than a photon having to use the LWA ("long way
around"). But I agree, that of course would be good enough, who cares about semantics when we talk about science, right?. Agreed, theoretical physics
and general relativity allows for wormholes to be possible. The problem only is: The energy required to create a wormhole and keeping it stable and
making it big enough for a space ship is so enormous, it probably would require all energy in the universe. But lets say you could do that, what
happens then? The moment the space ship enters the wormhole, the "tip" of the space ship gets accelerated to just under light speed while the rest
of the space ship still is outside of the wormhole. Long story short, your aliens would most likely be a nice ball of pulp, when they come here. Just
make the calculation with the assumption that your space ship has a mass of just 1 metric ton and accelerate it to light speed (e=mc2), then look at
the numbers you arrive at for the energy and the mass your space ship (and its crew) will have when it approaches light speed... enough said.
Another thing: the exit point of the wormhole would create such a spectacular light show that when your space ship exits, you'd actually have your
proof of alien visitation. Not even the most sinister government conspiracy could cover up that one.
Oh yeah, one more thing (to quote the late Steve Jobs): Let's say the aliens can do all that, there is one more problem: for them, the travel time
from their planet to ours would, let's say, take only seconds. However, to us, it would still be millions of years. Given the almost daily UFO
sightings, a whole slew of alien civilisations must have decided to visit Earth a few million years ago and drop in right around the same time. Which
also means, one cannot have met the same UFO crew if they're going back and forth between Earth and their planet. Time is relative, remember?
So this goes out to the "non-believers", show me one thing which proves aliens cannot come to earth and are not here now?
Well, I showed you a few things. May I turn the table back now?
