in high spirits - gravity aliens would beshort and stocky , and have stronger muscle and ivory . They ’d also be more potential to live underwater , which might make it hard for them to develop much engineering .

They would have a much harder clock time getting into space . The high your gravity , the more thrust you demand to reach escape cock speed . We ’re lucky we have such an leisurely meter achieving orbit , but other mintage might not even put up satellites until much later .

A much high gravitational force planetmight not have an O atmospherethat we could breathe . The gamy soberness would keep too much hydrogen around for free oxygen to grow .
