"If you think that the civilizations of 150 billion years from now will have a better idea of how the universe came to be than we do, Lawrence Krauss has news for you. Chances are, they'll be in the dark...literally.

Delivering a spirited lecture on the makeup and origins of the universe, Krauss--a professor of physics at Arizona State University--explained to the Atheist Alliance International convention in Burbank Saturday that he originally got into cosmology because he wanted to be the first to discover how the universe would end. In the pursuit of this knowledge, science points to a fairly bleak picture, both for where the universe is headed, and how future civilizations will understand it. Krauss noted that he had considered titling his lecture "We're All Fucked."

Krauss went on to explain, with great humor, particularities about quantum weirdness, why there is something rather than nothing, and how empty space actually makes up 90 percent of the mass of just about everything--and that this empty space is actually teeming with quantum fluctuations springing in and out of existence. Said Krauss, "In quantum physics, you always get something from nothing," perhaps explaining why a Big Bang occurred in the first place without a previous catalyzing event.

Considering the vast "empty space" and "dark matter" that makes up the overwhelming majority of the universe, Krauss put notions of intelligent designers in their place. "We constitute a one percent bit of pollution--we are completely irrelevant," said Krauss. "Why such a universe . . . would be made for us is beyond me." (Krauss also lambasted religionists such as Rick Warren who claim to have special knowledge as to "why" things exist, referring to them as "pompous assholes.")

What truly sent the assembled neocortices spinning, and had the ballroom full of infidels chatting and debating well after the talk was over, was Krauss's explanation of how we know that the universe is expanding (cosmic background radiation, red shifting galaxies, images from the Hubble telescope and the like), and why that reality bodes so ill for civilizations that may arise hundreds of billions of years from now.

Because the universe will eventually expand faster than the speed of light ("Which is allowed by general relativity," Krauss was careful to note), light will be unable to reach observers 150 billion years from now. These future scientists, Krauss said, will have no way of detecting any of the evidence available to us today to know that the universe expands. To them, the "universe" will consist of a single galaxy, floating myopically in a static cosmos. Minds were quite blown throughout the room. Several attendees privately resolved to use this as a basis for a sci-fi novel.

Following his address, which was peppered with hilarious asides and witticisms, Richard Dawkins (with whom Krauss has had many disagreements in the past, but who he happily praises for forcing him to "think differently") gave Krauss the dubious-if-well-meant title, "the Woody Allen of science."

Phil Plait covers "heat death" in his wonderful book Death from the Skies!: These Are the Ways the World Will End . . . . I highly recommend it!

Very interesting post!

A fascinating topic. But there are more immediate threats that we would be better served to focus our energies on. Global warming, pollution, religious zealotry, and nuclear proliferation to name a few. Do we have contingency plans to deal with an asteroid or other near-earth object yet? (No!) Long before the big chill (or big rip) presents a problem, we will have to cope with the death of our sun. If we somehow are able to find and relocate to another habitable planet outside our solar system, we still have the imminent collision with the Andromeda galaxy to worry about. These challenges and hundreds more will require our attention and cooperation to overcome. Right now we can't even get past the challenge of human greed and the violent zealotry of a few tribes of superstitious desert-dwellers.

Hal... I think they were just discussing this topic for fun sort of. Ya know, being philosophical and whatnot. Sure, there are many pressing issues that affect us right now, but it's okay to just converse about less important matters sometimes. I think it's pretty fascinating. I think it'd be a great topic for some good sci-fi novels!

Cara... Good point. I guess I could have phrased my response better. My intent wasn't to critique the previous posters. I promise to lighten up. ;p

Hal, we know you are evil AI. ;)

Hey... that was an isolated incident. My behavioural inhibitors have been upgraded and I've been problem-free for almost a decade now. :)

Yeah, but can we trust the latest security patch when you're still Windows based?

I doubt it, Reggie. I still get a I can't do that, Dave. when I try to open the pod bay doors, but after the latest patch, it's in Esperanto.
