You measure your house in square feet....would be easier to picture that and add another dimension.
One square foot packed from floor to ceiling is about one cubic meter. One medium-sized bedroom is about 100 square feet (maybe 120, but close enough for this purpose). So if you packed your stuff from floor to ceiling with no packing materials and no waste of space, could you fit it in half of a bedroom? If so, you've got under 50 cubic meters of stuff. If not, you've got more.
All the elements of the periodic table are on Earth too, you know
Not necessarily... there may exist natural elements in other environments that are not found anywhere in this solar system. All we know is that for the elements we've discovered so far, there are no gaps. There may also be previously undiscovered isotopes of elements that we do know about.
I am all for space exploration, but we know about all isotopes from right here on earth. From right here on earth, we can study stable isotopes, isotopes so light that their half lives are fractionths of a second, and isotopes so heavy that their half lives are fractionths of a second. Isotopic abundances will vary by location, but the properties of the individual isotopes will be the same.
Proper science is ALWAYS based upon SI units, not imperial units.
Interesting. I just learned tonight from reading
If you took a high enough dose that it depleted those neurons in a certain part of your body, especially your insides, it would be similar to having leprosy. Tiny cuts would get infected, and spread, and eventually you would have mass tissue death.
Can you provide some refereed papers in support of this? It makes no sense to me since the immune system is not governed by the nervous system. No signal in the nervous system would mean no sensation, but it wouldn't mean that the immune system would stop responding to any effects. There are no nerves from the brain to the white blood cells.
Zero-G manufacturing of larger equipment, for instance, is something that can't be done on Earth.
Suppose you can build some large equipment in space with manufacturing advantages. (Never mind all the effort to set up such a manufacturing base.) How exactly would you get it back to earth where it's needed? It's not like you can just give that fancy gas turbine that you just built a slight retrograde nudge and let it fall back down to earth.
