The fact that this chain of life existed [at volcanic vents on the seafloor] in the black cold of the deep sea and was utterly independent of sunlight - previously thought to be the font of all Earth's life - has startling ramifications. If life could flourish there, nurtured by a complex chemical process based on geothermal heat, then life could exist under similar conditions on planets far removed from the nurturing light of our parent star, the Sun.

I prefer sayings over jokes.

There are more active volcanoes beneath the sea than on land by two orders of magnitude.

Everyone is an explorer. How could you possibly live your life looking at a door and not open it?

I mean, there is amazing amount of oil and gas and other resources out beneath the sea. It's staggering.

So, you know, I think the age of exploration is just beginning, not ending, on our planet.
