Waiting for an apocalypse? Maybe it will take a while, space travel is difficult for aliens – and now there is a reason why they can not explore space. Super Earths, the livable alien zone for scientists, are planets like ours – only much larger. The exoplanets have an attraction that makes it impossible for civilization to come out there. This is because a spacecraft would have difficulty negotiating its extreme gravity, as the required space flight would be extremely expensive. Therefore, aliens get stuck in their habitats.

How difficult is it to launch a rocket from a super-Earth?
- Very. For humans on Earth, it's relatively easy to get into space because the magnetism of our planet is not too strong
- Researchers in their new study have calculated that the attraction of a super-earth means that it's almost impossible to launch would be a spaceship of the great planets
- To bring the equivalent of an Apollo lunar mission into orbit, Hippke's estimates showed that a rocket would require a mass of about 440,000 tons (400,000 tons) equivalent to the Great Pyramid of Giza in Egypt. In addition, rockets would travel 40,000 miles an hour to escape Earth's gravity. The gravitational force in habitable planets that are larger than Earth is at least 2.4 times greater than that.
- So, to fly so fast, rockets need to carry a lot of powerful rocket fuel to escape their superpowers' weight – that is, they need more fuel to take off
Michael Hippke, a researcher at the Sonnenberg Observatory in Germany, told Space.com:
On space flights, space flight would be exponentially more expensive
He added that " such civilizations would not have satellite TV, a moon mission, or a Hubble Space Telescope. "
The Gravitational Power of a Super Earth also Has Benefits
NASA has previously discovered that it is larger – life planets could be extremely good if they are in a habitable zone around their star (also called the Goldilocks Zone) be suitable to support life, as the strong attraction could pull in a dense atmosphere that would protect any life on earth Cosmi c shine.
So, can aliens never escape the super-earth?
The only thing that would serve an alien civilization fleeing super-terrestrials would be to invest in exponentially more expensive rockets or opt for the nuclear option. 19659016] A nuclear pulse-propulsion system that uses a series of atomic bombs instead of normal engines to propel a rocket could overcome the heavy gravity of such a planet, but according to Hippke it would be a huge risk.
A Failure to Start What normally happens with a 1% risk could have a dramatic impact on the environment … I could only imagine that a company would take these risks in a flagship project where no other options are available but the desire is strong – for example, a single mission to leave their planet and visit a moon

We humans are lucky not to be on a super-earth
Hippke talks about how people are better off and do not live in a super-earth:
"I'm surprised to see how close we are to people on a planet that's still light enough is to make a space flight. "
"Other civilizations, if they exist, might not be so happy," he added. Instead, they would to a certain extent be arrested on their home planet and, for example, use more lasers or radio telescopes for interstellar communication rather than probes or spaceships.
Super Earth civilizations are much less likely to explore the stars
", Hippke speculated.
