We're so lucky to be born alone into such a vast vacuum totally incapable of supporting our version of life (give or take a few atmospheres).


ISTR seeing a NASA documentory that stated that all the stars/matter in the observable universe (Assuming one ignored the gravitational consequences of doing this :p) would fit into a volume only a couple of LY across.

Space is pretty empty really! :eek:

Yep, in fact in terms of Energy content the universe as we know it is made up of only 5% baryon if matter (the "normal" matter we see around us essentially), with around 25% being Dark Matter and the remaining 70% is Dark Energy (which we have very little understanding of at the moment). It is a fantastic time for Physics, there is so much that we still do not know and we are in an age of technology where we can begin to really delve into these mysterious depths of Physics.

The next decade or so is going to be incredibly interesting for High Energy Physics and cosmology, even this Summer could have the potential to bring about some more fascinating discoveries due to the LHC coming back online at double the energy of previous runs (it will now run at ~14 TeV if everything goes to plan).

Matter has a lot of 'empty space' inbetween all those forces propping up it's structure too. There's just, emptiness,...everywhere....:(
