No, because the surface gravity is also a function of the distance to the centre. The G-force is directly proportional to the mass and inverse-square proportional to the distance. Assuming the same density as Earth, a world of seven times the mass would be roughly double the diameter. That would mean 7x Earth mass divided by 4, or just under 2g, so you’d only weigh about 400lb.
Hmm... So (hypothetically speaking), if Obama fell out of Air Force One at 30,000 feet, what would the G-force on his head be at impact?
Just askin'...
“...so you’d only weigh about 400lb.”
In other words, you’d be Ogliese.
“so you’d only weigh about 400lb.”
Oh! Well! Only 400 pounds? No problem! 8^)
