# How can the big bang be “observed”?

The Big Bang Observer is a proposed spacecraft to study gravitational waves. Especially the one that are thought to originate from the Big Bang. Question. How can we observe waves that has an origin at the beginning of time? Doesn't it implies then that we were there when it happened so that the wave were created and then travelled to us?

The aim of the Big Bang Observer would be to study gravitational waves generated during the inflationary period that took place some $$10^{-32}$$ seconds after the Big Bang.
This is what is meant by observing the Big Bang. We would be literally observing the gravitational waves that were generated $$10^{-32}$$ seconds after the Bang Bang and have spent the time since then travelling towards us.
