: “The more massive a planet is, the more the spaceship to espace from it becomes gigantic” 🌍🚀
Why are the aliens still not visiting us while our galaxy is so old ? Scientists may have a new serious answer to this big question known as the .
Generally, astrobiologists suggest that the appearance of life is easier on a Super-Earth (a rocky planet more massive than ours). Indeed, bigger gravity leads to a thicker atmosphere which increase the probability for life to develop. But an article written by Michael Hippke in May 2018 showed that the release speed to leave a planet with a rocket was exponential related to its gravity.
👉🏻 In other words, the rocket Saturn V from Apollo’s missions would have needed 56x more fuel to took off from a Super-Earth only two times bigger than our blue planet. 🤯
This is maybe the reason we still have no contact with some extraterrestrial bodies: because they can’t afford space travel.
What do you think of this? Do you believe there is life elsewhere in our galaxy ? 💭👽
