Why Do We Want to Know?
It is a fundamental fact of human nature that we are
inquisitive. We want answers! Over years, decades,
and centuries science has been guiding our thought processes,
helping us find answers to age old questions:
is the Universe all there is? Did it have a beginning,
and will it have an end? These questions were once firmly
in the realm of philosophy, but with advances in our
technology and our understanding, we are now just beginning to
get the answers — but behind them are still more questions.
The Universe did have a beginning, 13.7 billion years ago.
But how did that happen? What did the universe look like
when it was very young? Will the expansion of the Universe,
so recently understood to be accelerating, continue forever,
or is there another possibility?
SNAP will be able to provide needed data so that
scientists can continue to answer these most basic and
profound of all questions — and, no doubt, will raise
even more questions we have not yet thought to ask.
