I'm sure we're not alone in this huge universe. The trouble is trying to find others. We need a way to make the 'bigness' of space displaced so we can travel not through our own galaxy, but to all the galaxies. But who am I kidding, we can't even get enough funding to look for Earth crossing asteroids which will cause ELE's.
