Explanation:
Mass = m
Velocity = v
If Mass is increased 4 times = 4m
New velocity = 2v
Kinetic Energy
So it will be 1/2 × 4m × 2v × 2v
so Kinetic Energy will increase 4 times
Our skelotns would have to change as, they require less pressure and so on. Even now we can only survive a certain time in space.
