Should be dam happy were that small, else we would have been hit by a metor a long time ago.
a meteor and, we have, have we not ?
as for sun exploding, it will be a long way off unless some pillock sends a stargate attached to a black hole into it
theres a slim chance i was bored and rewatching some stargate episodes today.
most impressive thing in that video is, google earth sure got good, is that in the next beta or something. Realistically in our life times we won't be visiting other planets, colonising anywhere or traveling very far. though i guess to be fair, there is a decent chance some planet somewhere has a species that has cracked space travel. most species inteligent enough to get that far i just can't see being hostile, theres just as much chance of them coming here during our generation as there is in 200 years, or 20,000 years. i can't see us creating a way to travel ourselves but its in the realm of possibility "aliens" could come and show us how to travel which would be cool.
chances of an alien race getting quite advanced aren't that high. probability that a alien species is out there is high, but it took literally billions of evolutionary advances to get us where we are now, thats the difference. chance of a basic species is high, chance they also survived evolution and became highly inteligent is pretty damn low even when you take into account how many planets there are.
Either way, to be able to travel to other solar systems, see things like binary star systems, other planets, other life, oh well.
