Everything you can observe — stars, planets, galaxies — is only a fraction of what exists #TEDTalks

The universe that we know, with its luminous stars and orbiting planets, is largely made up of elements we can’t actually see — like dark energy and dark matter — and therefore don’t fully understand.

The universe that we know, with its luminous stars and orbiting planets, is largely made up of elements we can’t actually see — like dark energy and dark matter — and therefore don’t fully understand.

      @jonnanderson6489 small correction a theory is not “in search of evidence” a theory fits the evidence we have gathered so far. a hypothesis requires people to go out in search of evidence.
