Ok. Let me say English is not my first language, so I’m using Google translator for the most part of this post.
I’m not a skeptic. I have seen a UFO years ago.
This is something i just realised.
I’m not into Physics, so this could be all bullshit.
The average gravitational pull of the Earth is 9.8 meters per second squared (m/s2)
Moon: 1.62 (m/s2)
Mars: 3.71 (m/s2)
Jupiter: 24.79 (m/s2)
We have all seen the footage of the Apollo missions where we see the difficulties that the lunar gravity presented to the astronauts.
Having less gravity, they moved by jumping. The muscle and strength of an average human generated a greater impulse with the lunar gravity. On Mars (3.71 (m/s2)) something similar would happen, but to a lesser extent.
And if we went to Jupiter, it would be the opposite. We would have more than twice the gravity.
The body would feel much heavier. I think our body is not prepared to withstand that gravity for long.
So (here begins my theory) what would happen to an alien if he visited Earth?
If they came from a planet or dimension where there was less gravity than on Earth, they would have a thinner body, with less developed muscles (greys?), but if they landed on Earth, with the gravity we have, they would have serious difficulties moving around. With less muscle, they probably wouldn’t withstand the 9.8m/s2 for long, and clearly couldn’t stand up. Less so, if we consider that they are depicted with large heads in relation to the size of their body.
If an Alien came from a planet or dimension where there was more gravity than on Earth, he would have a more developed body. More muscle and bone structure. This would allow them to move around in an environment as hostile as Jupiter’s gravity: 24.79 (m/s2). These Aliens, to move around on Earth, would have to do it by jumping (similar to what happens to humans on the moon)
So. To be able to land on Earth and not float (due to lack of native gravity) or be crushed by a higher gravity than the native one, these aliens:
a. They are of terrestrial origin and are accustomed to this gravity.
b. Their planet or dimension has a gravity equal to Earth’s… and in this case. How many chances are there that the planets that could be inhabited have an equivalent gravity?
The images we have seen in movies and series, of aliens coming down from ships walking without difficulty, did not contemplate this problem and led us to think that they could walk normally. But no. Their way of moving around on Earth would be seriously affected if their planets had either more or less gravity.
What do you think?
