Scientist Reveals Why Aliens On Super-Earths Haven’t Yet Contacted Us

The scientific community largely agrees that there are aliens out there somewhere. Some planets in the outer space might host far more advanced civilizations than us. So, why haven’t aliens been able to contact us or reach earth yet? A startling new study says they might be trapped by gravity on their respective planets. A higher gravitational force could make it difficult for the extraterrestrials to leave their home and explore other planets.

Michael Hippke, an independent researcher affiliated with the Sonneberg Observatory in Germany, says in a new research paper that most of the exoplanets suitable for hosting intelligent life are larger than our own planet. The ‘Super-Earths’ are 1.2 to 2 times larger than earth in diameter. Their mass could sometimes reach up to 10x that of our planet. It leads to doubling up of gravity on the Super-Earths.

On exoplanets that are 2x the earth in diameter, you would weigh twice as much as you do on the earth. Since the gravity there is far stronger than earth, aliens will have a lot of difficulty leaving their home planet if they are using chemical rockets like we do, says Michael Hippke. It means aliens will require huge amounts of fuel to escape their surface gravity and travel into space. Space flight for them might be extremely expensive if they lack high-end technology. Maybe aliens haven’t found their Elon Musk yet.

Hippke tried to figure out how much fuel would be required to launch a giant rocket from the Super-Earths into outer space. Aliens would have to build extremely massive rockets and use a sizable fraction of their resources as fuel for the rocket launch. It would dramatically limit the number of flights to the outer space. Spaceflight on the Super-Earths would be “exponentially more expensive,” said Hippke.

Too many difficulties might be preventing the civilizations from Super-Earths to explore the space. They are “to some extent arrested on their home planet.” Hippke says aliens are more likely to make use of lasers and radio telescopes for interstellar communication rather than sending spaceships or probes.

However, it would not be entirely impossible for them leave their planet. If aliens wanted to send rockets from their planets, the rockets need not necessarily been twice as big as our spacecraft to escape the gravity. As NBC News points out, the SpaceX Falcon Heavy rocket weighs about 1,500 tons, and can take 17 tons of material into deep space. On a planet 2x the diameter of the earth, it would take a rocket weighing 15,000 tons to perform the same task.

That rocket would be about twice as high as the Falcon Heavy rocket or 40% larger than the Saturn V rocket that took astronauts to the moon nearly 50 years ago. It’s not impossible at all. People on Super-Earths could have more diversity of life forms, a thicker atmosphere, and more abundant resources. All these factors should help intelligent life evolve faster than on the earth.

Even if a stronger gravitational force and other challenges delayed the aliens from leaving their planets for a century or two, how does it matter?

Separately, a team of physicists claims to have found evidence of ancient water on the moon. It could offer proof that aliens once roamed around on the moon because water is critical for life to evolve. Researchers from Japan and Germany examined 13 lunar meteorites using advanced microscopes. One of the meteorites called NWA 2727 contained moganite, a mineral containing silicon dioxide.

Moganite on earth forms only when alkaline liquids are trapped under high pressures. The study was published in the Science Advances journal. Last month, astronaut Buzz Aldrin passed a lie-detector test while being quizzed about his encounter with an alien. Neil Armstrong and Buzz Aldrin were the first people to set foot on the moon. Aldrin has said on many occasions that he had spotted a UFO on the way to the moon. He said, “There was something out there that was close enough to be observed, sort of L-shaped.”

  1. So they knew nothing and while sitting around a fire at night they made up facts to help comfort themselves due to their lack of knowledge.
    They got the particulars confused and just about everything else wrong, and anything that they believed in that lacks proof is ok because “faith.”

  2. Every thing that happens is not caused by the Creator. He gives his creation the choice in the actions they take or do.

  3. It is just as much proof as any other proof out there!

  4. My guess is that if you wonder around the desert exhausted, suffering from lack of hydration and heat stroke you may consider a mirage to be a burning bush. Hearing voices at that point is not really a big surprise. Best not to make any major decisions or form solidified opinions based on these types of ancient stories.

  5. There may be a creator. He playing with us like a 10 year old plays with insects.

    And if there are aliens so advanced they can travel to our world, they likely don’t have any interest in our puny primitive planet. Just as we don’t run around visiting every ant hill we see.

  6. smart goat herders,who were not ego maniacs and knew instinctivly that there was some one greater than themselves, they may have gotten the particulars confused but they got the message right..

  7. so a book written by goat herders is proof?

  8. With the universe about 13.5 billion years old and our earth about 4.5 billion years old intelligent life surely has evolved on other planets. Now just why would this intelligent life have to evolve on a heavier gravity than we have? The probabilities that life as our life is here on earth did not evolve on other planets is purely illogical. So even if life developed on a larger earth there should be a plenty of planets out there similar to own where life developed and developed before life on earth did. It is purely illogical to think that if life did develop on one of these planets that think that it would not be far more developed than life on this planet is. So there must another reason why no extraterrestrial has have been found.
    Since there is no scientific reason that more intelligent life is not out there. For the sake of argument we will say that there is intelligent life even more intelligent life than we ourselves have. Then there must be another reason that they have not contacted us or responded to our attempts to contact them. That reason may be that in their greater intelligent they know that the population of the earth has not evolved to a degree that it would be wise for them to contact us.
    Well there is another reason which is similar in away and that being is that there is a Creator. That Creator created more than one planet with intelligent life. Each planet the Creator gave His creation the choice to choose unending life or death. To test the intelligent creature He placed a test on each planet. That test was another creature, a very powerful creature which stood in opposition to the Creator but that creature could interface with these other creatures would be at only one place. But the sad thing is that the creachers of this planet chose to gratify self today and not worry about tomorrow. they chose death. But the Creator stilled wanted his creation to be with him so he provided a way.
    Now to show this is the way it happened read the first few chapters of the Book of Job.
