If you're puzzled by what dark energy is, you're in good company.
From Saul Perlmutter
For almost a century, the Universe has been known to be expanding as a consequence of the Big Bang about 14 billion years ago. However, the discovery that this expansion is accelerating is astounding. If the expansion will continue to speed up, the Universe will end in ice.
We have a remarkably complete picture in many ways - and it could be that we're not accounting for something that's almost three-quarters of the entire universe.
This new understanding of processes on Europa would not have been possible without the foundation of the last 20 years of observations over Earth's ice sheets and floating ice shelves.
I will say that growing up as a kid in an urban environment and having lived in cities all my life, the one achievement that everyone can look forward to is getting the perfect parking spot.
I tend not to dwell too much on ultimates.
Probably the single most important thing about the Nobel Prize for most people is whether they get the coveted parking space on campus.
You might expect gravity would slow it down, but it's just expanding faster and faster.
This is the kind of discovery that resonates.
If you ask almost any of them, 'Do you stand behind your theory? Is this the answer?' I think almost everyone would say, 'No, no, no. I'm just trying to expand the range of possibilities.' We really don't know what's going on.
