If extraterrestrials exist, why don’t they visit planet earth?
The existence of extraterrestrials has always been questioned both by the governments of the world and by the scientists and ufologists of the different space agencies existing on our planet. Over the years we have come across some evidence that can verify that aliens, in addition to existing, have visited the earth on countless occasions, in fact, many people claim that these space beings have secret links with top U.S. military commanders. Now, is it 100% safe for aliens to visit us?
Suppose that extraterrestrials do indeed live on a planet distant from our solar system, such a celestial body must be large enough to accommodate the different races that exist, for example, reptilians, Greys, humanoids, etc. What if they have not formally visited us because there is something that complicates their journey from their planet to ours?
The force of gravity on those planets requires ships with more fuel for the aliens to get there.
Jaime Maussan, a German astrophysicist, comments that the planet that could be inhabitable by aliens would be 10 times larger than the earth, that is, a super planet. In this sense, their gravitational force is much greater than that of our planet, in addition to an extremely thick atmosphere and their ships, when making an interstellar voyage, would need a greater amount of fuel and energy, so that they cannot be stranded. If the ships don’t have these components, it’s very likely they won’t even be able to get out of that atmosphere.
According to calculations, the alien ship should have as much fuel as possible, reaching at least 44,000 tons, which is equivalent to the weight of the Giza pyramids, one of the 7 wonders of the world. Compared to human technology, the Falcon Heavy is only 1,400 tons and the best rocket available today.
Extraterrestrials may indeed have superior technology to us, but even so, imagine the size of the spacecraft that would be needed to transport that amount of fuel, in addition to the crew members.
