If the Earth kept the same mass that it has now, but that same mass got packed

into a sphere with 1/2 the present radius, then a man who weighs 100 pounds

on Earth now would weigh 400 pounds on the half-sized Earth.

If the outer shell of the Earth's mass were removed and discarded, leaving only

the mass that's presently inside 1/2 of the Earth's radius, then a man who weighs

100 pounds on Earth now would weigh 50 pounds on the half-sized Earth.

(Assuming that the Earth's mass/density is homogeneously distributed.)

(This is all my opinion & I could be wrong.)
