It's an unusual opportunity, a chance for so many people to share in the excitement and the fun of the fact that we may be on to hints as to what the Universe is made out of. I guess the whole point of a prize like this is to be able to get that out into the community.
It's interesting to wake up at 3 in the morning by someone saying they're a reporter and they want to know how you feel. I felt fine, but I said, 'Well, why do you ask?'
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.
The original project began because we know the universe is expanding. Everybody had assumed that gravity would slow down the expansion of the universe and everything would come to a halt and collapse. The big surprise was it was actually speeding up.
It seemed like my favourite kind of job - a wonderful chance to ask something absolutely fundamental: the fate of the Universe and whether the Universe was infinite or not.
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.
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.
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.
From our point of view, the most exciting thing would be if we discovered something really fundamental in our understanding was just off a bit - and that now we have a chance to revisit it.
So it's possible that someday, by understanding a little bit more about how the world works, it will come back to help us in some other way that will be surprising.
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.
You don't want to come out with anything that's wrong, of course, in a scientific, you know, a major scientific announcement, and so you're being so careful trying to check, well maybe it's this, maybe it's that, you're looking at every possible thing.
You want your mind to be boggled. That is a pleasure in and of itself. And it's more a pleasure if it's boggled by something that you can then demonstrate is really, really true.
