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.

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.

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.

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.

What we were seeing was a little bit like throwing the apple up in the air and seeing it blast off into space.

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.

There are still so many questions to answer. When you look at any part of the universe, you have to feel humbled.

Probably the single most important thing about the Nobel Prize for most people is whether they get the coveted parking space on campus.

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.

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.

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.
