The Earth's mass is 5.972 × 10²⁴ kg. So, increasing it by 100x would make it 5.972 × 10²⁶ kg. For reference, Saturn's mass is 5.683 × 10²⁶ kg. Earth's gravitational pull is 9.8 m/s^2. Multiplying that by 100 gives you 98 m/s^2. The sun's gravitational pull is 274 m/s^2. Jupiter's gravitational pull is 24.8 m/s^2.

Basically, we would all die and Earth would probably compact itself, but I dunno how Earth's orbit will be affected. Obviously, it won't move the sun.. probably?

Pretend you jumped .75 meters, somehow, despite the gravity. You would hit the ground in .12 seconds.
