Aliens on the globe have to

they need to take themselves out of their habitat if they want to escape because the gravity is so strong that they will attract them back, scientists said recently.

For humans on Earth, it is relatively easy to enter space because our planet's gravity is not so strong. However, on the super-Earth-like planets similar to ours, much larger ones will be much stronger, making it harder to escape.

Aliens' habitat has a powerful gravity?

Planets around other stars that have similar conditions to Earth may have up to 10 times the mass of the Earth.

Previously, NASA had discovered these supernovae . If they are in a specific area around certain stars, the supernova will be very suitable to support life because strong gravity can pull into a dense atmosphere, protecting any Live on the planet from the harsh universe. However, it will be difficult for a wise civilization on these planets to launch missiles because gravity will make the process impossible.

This is why a group of scientists have provided potential solutions for aliens to read their research, saying they can use a catapult to escape gravity.

Alex Howe, an astrophysicist at the University of Michigan in Ann Arbor, and the lead author of this conceptual study, said: "My initial reaction when I first heard about the catapult was "It can't be done." After that, I calculated, and surprisingly, if I succeeded in designing this launcher, we could save a lot of fuel and energy. '
