The further I read, the smaller I feel.

The Total Perspective Vortex is allegedly the most horrible torture device to which a sentient being can be subjected.

When you are put into the Vortex you are given just one momentary glimpse of the entire unimaginable infinity of creation, and somewhere in it there's a tiny little speck, a microscopic dot on a microscopic dot, which says, "You are here."

Not a physicist, but the basic idea is that the probability for anything to happen is different than 0, even if extremely small.

The quantum fields can't ever be zero, from my understanding. And thus stuff can still happen:

While the topic is on. I am trying to find a short story I read some years ago (4-5) about the evolution of life on our planet in the far future. Warning, massive spoilers: There are like 5 or 6 mass extinction events followed by a new civilization each time built by a different specie. At some points a raven civilization goes on the moon (they always had an innate tendency to go higher) and find an old rover, then i…

How could the Earth be totally smooth?

Dunno. Also, the author hints than the night is endless and cold and the child, which the author uses to convey that part of the story, is scolded by his parents and ordered to get back underground where it's warmer.

My understanding of it is that it wouldn't reach zero Kelvin. The heat only becomes uniformly distributed. Everything becomes maximally disorderly. Things move, but all interesting information is gone.

But order is probabilistic. It's not physically impossible for order to increase, it's just ridiculously unlikely. If you wait long enough (really long) it'll probably happen some time.

I don't think quantum effects are especially related, except to the extent they relate to everything.

Earlier quoted context omitted.

The further I read, the smaller some of the issues we face today seem. I could spend my life fighting to prevent global warming or fix the world, but this list just makes me want to enjoy the time I have here with my loved ones... I don't know how I feel about these feelings.

You mean, it doesnt make you want to get into an inconsequential political argument with someone on Twitter?

It's truly a shame that more people don't realize how much better you can feel about life and humanity when you stop getting drawn into arguments on social media.

Amazing that the entirety of human civilization as we know it fits in a smaller time scale than the very first event on this timeline (10,000 years from now). So while these time spans are minuscule on an astronomical scale, they are enormous on a human scale.

Indeed. In Neil DeGrasse Tyson's version of "Cosmos" there is a great illustration where he says that if we visualize the entire history of the universe as being scaled to one calendar year then every human being that has ever lived has essentially existed somewhere within the last 12 seconds of that year.

> The length of the day used for astronomical timekeeping reaches about 86,401 SI seconds. Under the present-day timekeeping system, either a leap second would need to be added to the clock every single day, or else by then, in order to compensate, the length of the day would have had to have been officially lengthened by one SI second. Can you just imagine the amount of legacy code with DAY_SECONDS=86400 out there 5…
