There's a long list of technologies that have now made it possible to carry out very precise search efforts in the deep sea.

I mean, technology is amoral. It has no morality.

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

Almost a quarter of our planet is a single mountain range and we didn't enter it until after Neil Armstrong and Buzz Aldrin went to the moon. So we went to the moon, played golf up there, before we went to the largest feature on our own planet.

Forever may it remain that way. And may God bless these now-found souls.

Fifty percent of our country that we own, have all legal jurisdiction, have all rights to do whatever we want, lies beneath the sea and we have better maps of Mars than that 50 percent.

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.
