39 light years? how are we going to get past the vanhalen belt (lol) let alone attain light speed. i cant see that happening in the next 100 years, the aliens built that barrier around earth to keep us here.

If we do... jump... ahead 400 years, maybe the whole gravity thing will be figured out. Then no super force field needed. Just a regular one. But first, an engine and a power source.

So, assuming you've seen DBZ or something similar, if we could survive, would it perhaps be possible to "train" there to be stronger or do you think its more likely that our bodies would shut down or collapse?
Just bouncing around some thoughts.
How Much Gravity Can Humans Handle?
Humans are a very adaptable species. We do have our limits though. According to NASA’s Ames Research Center’s expert on humans in space, a person has survived 2x Earth’s gravity for 24 straight hours without ill effects. They go on to claim that it is theoretically possible for a human to adapt to a gravity environment that is between 2x and 3x that of the Earth. However, they say that at 4 times Earth’s gravity (4G) or above, human physiology cannot maintain sufficient blood-flow to the brain.
In the future, it may be possible to break the 4G limit with enhancements in genetic manipulation and extremely strong mechanical replacement organs to keep our body’s systems running, but that technology is a long way off.
What do they mean when they say "without a substantial gas envelope"? Does that mean a lack of atmosphere or just not as thick of an atmosphere as say venus?
