With "zero" gravity, inertia becomes more important, but certainly not stronger or weaker.

there is no gravity in space
They did a test to see if you could use inertia as artificial gravity. It didnt work the person still had a bad back when he came down.

ummm... Could you explain that one a little more? Or maybe drop a link. I'm not sure I understand what you're saying.

Sounds like you mean a rotating ship type dealy. We don't have anything big enough to avoid significant force differentials at different heights.

I think what he's referring to is the proposed use of a "rotating section" on a spaceship to generate an artifical gravity, much like you see in Babylon 5 and 2001: A Space Oddessy.

I guess muscle loss/atrophy (sp?) still occurs in this simulated enviroment, although I would expect it to occur more slowly than in a non-simulated gravity enviroment.

Then again I may be completely off my rocker.

2. We dont see them and the optics to see them will need a very wide base line.

and with mars there just is not a reason to do it until we have micro machines that can turn rust and CO2 into steel and O2

quite soon - in 25 years probably, we should have an operational interferometer telescope in space capable to see Earth like planets around nearby stars.

Converting C02 to O2 is no problem - plants have been doing it for many million years A little genetical engeneering and we will have algae capable to live on Mars providing there is enough water underground.

yes millions of years
and thats how long it took to put O2 in the air millions of years...
yes 25 years from now we will see planets a few light years out, but as i said there isnt going to be that many good planets to see.

And how do you know ?
May be there is a shiny blue planet orbiting Alpha Centauri !
