Even more "mind shivering" than this one was a linked article about Boltzman brains ( http://en.wikipedia.org/wiki/Boltzmann_brain ) which I had never heard of before.

We are Boltzman brains, no?

No, I'm a Boltzmann brain. The rest of you are just a figment of my imagination.

"At 15:30:08 UTC on Sun, 04 December 292,277,026,596 AD, the Unix time stamp will exceed the largest value that can be held in a signed 64-bit integer.[84]"

i like that they give a precise time and date, given that the Gregorian calendar is basically meaningless on such scales. (also neither the earth nor the sun will still be around in any recognizable form....)

aint that funny how we paint future in such a dark colors (since sun will die in 5 billion years) and assume we all gonna die with it at the end, but yet we don't put humans evolution taken into consideration. "in 600 million years plants will die" -- seriously now? look when we have been 1,000 or even 100 years ago. think when we will be in next 1,000, given nuclear war will not push us back to the stone age. otherwise, in 600 million years we as humans will be able to scan entire universe and find perfect new home and teleport ourselves all plants and everything out there. think this is sci-fi? go back in time to 1900 and tell someone in 100 years you will have a palm size device of grapefruit weight that can gather information literally from air, play sounds, show motion picture, and you can interact with it by touching its colorful screen.

It's estimated that by 500,000 years from now on the Earth will have likely been impacted by a meteorite of roughly 1 km in diameter.

Here are the results of current attempts to track the objects that can potentially impact the Earth:

We are certain of one, not the other.

If your assumption is infinite time and complete entropy, yes it's correct. It's also why some level of common sense (e.g. Occam's razor) should be applied before such silliness is seriously proposed. I don't think Boltzmann assumes infinite time and entropy, just enough for the completely random emergence of sentient life that thinks (perhaps falsely) that it lives in a universe populated by similar beings who creat…

Implying that the Bible is "absurd" does not help the discussion and makes believers feel unwelcome. Please be nice. (I'm an atheist.)

The Bible as historical non-fiction is most certainly absurd, no implications about that. Not saying so out of sensitivity to those who believe otherwise does reason a disservice, just as not calling out Bolzmann because I don't want to offend him. If this makes anyone unwelcome, they should avoid places where their fragile ego might be challenged by rational conclusions. In a place like hacker news, I see no reason to let sensistivity toward faith restrict my speech any more than sensitivity toward programming language choice. Invite me for dinner and I will respect your religious and any other beliefs. Have a scientific debate in a web forum with me, and I will speak without concern for challenging you. It's not a personal attack to say the Bible is absurd - it's the truth.

The idea of Boltzman brains is a good reason to hope that the universe ends with a big crunch.

Error in Boltzman brains theory is that he assumes that universe with brains randomly fluctuated into existance into its current form , and concludes that this form is more complex than just brain and therefore brains without environments are more common (maybe iPhones or Bible are even more common then), and assumes that brain can exist without environment. also second law of thermodynamics states that resulting ent…

So... what your saying is that my master thesis won't write itself by some random fluctuations after all? I might have to alter my strategy.

Sure it will. You might have to turn it in late, though.
