Why hasn’t NASA been able to able to attempt Space Travel yet? I don’t really think it’s fair that the Aliens have been using it for like, so many years And we don't even know how it works yet. How many light years could it take for man to get to Jupiter or Saturn?

Which vibration is more severe: 1G @50Hz or 1G @ 500Hz (linear sine)? Rather than area under the curve is there other computional method? For random vibration, the amplitude is typically lower at higher frequency hence, for same amplitude at 50Hz and 500Hz which is more severe? How do one compute?

Basically, if I released CO2 into the bottle, how much pressure can it take before it explodes if external conditions are at 1ATM and ~70F?
And how much pressure is safe to fill it without fear of explosion (safety limits).
This is an empty standard coke/sprite type bottle.

I've read we are all made of stardust, that the atoms in our bodies could have once been part of a star and that they have been around since the creation of the universe.

So if this is true, could it be true to think that in some way after you die, after you decompose into the Earth, a worm eats the earth, a chicken eats the worm and someone eats the chicken then maybe the atoms apart of us now may make there way into another life and though I won't be me, I'll be aware of existance, alive again.

A bit of a sci fi take on the afterlife idea
