In a few thousand years of recorded history, we went from dwelling in caves and mud huts and tee - pees, not understanding the natural world
around us, or the broader universe, to being able to travel through space, using reason to ferret out the hidden secrets of how the world works, from physics to chemistry to biology, we worked out the tools and rules underpinning it all, mathematics, and now we can see objects that are almost impossibly small, the very tiniest building blocks of matter, (or at least we can examine them, even if you can't «see» them because you're using something other than your eyes and photons to view them) to the very farthest objects, the planets circling other,
distant stars, that are in their own way, too small to see from here, like the atoms and parts of atoms themselves,
detected indirectly, but indisputably THERE.
Capable of observing the Universe by
detecting light that is invisible to the human eye, ALMA will show us never - before - seen details of the birth of
stars, infant galaxies in the early Universe, and planets coalescing
around distant suns.
Though it's a long way from a few simple molecules to even the most basic proteins,
detecting chemistry similar to Earth's
around distant stars suggests that the pathway to life may be possible on other worlds.
