I just bought some KNO3 (stump remover) at the hardware store today and will be making my first attempt at DIY rockets in the very near future. I'll be starting with the standard 65/35 ratio and then working in other additives to fine tune. I'm using Spectricide brand KNO3 and cheap, grocery store table sugar purchased at Walmart. I'll be doing the cooking in a motel room that my employer rents for me when I travel, because if I blow myself up it'll be way more entertaining to do it in a motel. I plan on using heavy cardboard tubes (scrap material from work) for motor casings plugged on the ends with bentonite clay (kitty litter).

I'll post pics of my work as I go along assuming my IP doesn't get highjacked and give updates on mixes and results. If you are already doing this, chime in, post pics and rock(et) on!

Essentially formed because of a turbulent storm near the vortex creating two weird waves that makes hexagons naturally.

I know science doesn't care about our feelings, but tell me of any alternate theories other than everything freezing to death or being ripped to shreds that allows something, anything to keep on going and surviving.

Can we eventually develop the technology that allows us to "jump" to a new, younger or possibly truly unending universe with different laws of thermodynamics to carry ourselves on?

Hold me, /sagan/.

Humans design our gods and devils as infinite and eternal, because we are terrified of the fact that impermanence is the only constant. All of the desires that make us suffer the most are wishes for things not to change, or to change right away. They will. The universe doesn't appear to be headed for a big crunch, as poetic as that might be. It's ok! You can and will die. The universe can too. When it dies it will have concluded the grandest tableaux of stories we can even begin to imagine, and somehow: I doubt it will end there... Or it 'will', but the logical heuristic of an 'end' will not be final oblivion we imagine because we are flatlanders of the 3rd dimension trapped like amber in the 4th, or perhaps it will truly end, but it will only be one phosphorescent spark flanked by the countless other sparks of a firework show just beyond an opaque horizon that is profound to us, but elementary to infinity and eternity.

Don't sweat it homie, kick back and enjoy the show.

I like the hypothesis of what might come after universal heat death. If you know anything about Bose-Einstein condensates, you know that matter starts to act really weird when it gets close to 0Β°K. Groups of atoms and even molecules begin sharing quantum wave functions. Now imagine this on a universal scale. The whole universe and everything in it, whatever that might be, all having a single unified wave function. What might happen then? Given the untold eons of time available (assuming time will even still exist at that point) is is possible that the entire universe might experience some quantum event, say, tunnelling to "somewhere else"?

You already have a huge leg up! Light pollution makes one of the most crucial differences in how easy it is to take AP. I generally image in Bortle zone 8 (scale of 1-9), and down to a high Bortle 5 45 minutes out when I'm lucky. It's like squeezing blood from a rock... I'd have to drive over four hours to get to really dark skies (planning a camping trip this summer for that reason :) ) , but in places like that, you can get the same images I get near the city in a tiny fraction of the time (or far, far better ones for the same time investment)!

Not to mention, since your individual exposures/subframes would yield better signal : noise ratio, you could get by with much less precise tracking (and so more affordable gear, far less need for filters, etc).

And yeah, I feel you about people needing to check out the night sky more, but you have the benefit of those rural skies. I get why people don't look at it where I live. They don't have the optics or the patience, and who can blame their lack of immediate curiousity when to the naked it eye it's just a flat gray blanket with a handful of guttering pinpricks. They get consumed with what they can take, accumulate, illuminate, and guard on the ground, and the more paranoid and insular our mindsets get, the more we imagine the need for high-pressure sodium and mercury vapor lamps on every street corner. :( Light pollution is tragic and avoidable.

Remember those quantum experiments where the outcome changes depending on whether its observed or not?
There are some ideas that follow up from that and state that universe itself exists in its current state because there is an active consciousness observing it, and that it can be altered by said observations.

If flat earthers have their way, we'd all be living in fucking star wars, and not even the 'good' kind, the Disney kind, constantly full of retcons, bullshit asspulls, general irrationality and incompetence, as well as hand-waving mary sues destroying everything cuz they magic paladins.

If you poke into a piece of cloth and twist it it will follow that and make a spiral pattern. The harder you poke the more friction and the more it will be affected.

Another thread made me start thinking about this. The Fermi Paradox states (thanks, Wikipedia):

>The Sun is a young star. There are billions of stars in the galaxy that are billions of years older;
>Some of these stars probably have Earth-like planets which, if the Earth is typical, may develop intelligent life;
>Presumably, some of these civilizations will develop interstellar travel, a technology Earth is investigating even now, such as that used in the proposed 100 Year Starship;
>At any practical pace of interstellar travel, the galaxy can be completely colonized in a few tens of millions of years.

If that's the case, why haven't we been colonized already, or at least seen evidence of intelligent life somewhere in our galaxy?

My take: either A) Life takes a long time to develop, and somehow, improbably, we're the first planet to develop an intelligent civilization in our galaxy, or at least one of the first. We don't see anyone else because there isn't anyone else to see... yet, or we're all still too far apart.

Or b) Given the size and composition constraints of a planet able to foster and sustain life (as far as we know, "habitable zone," big enough to have an atmosphere, small enough to still be rocky, etc.) and continue long enough for said life to begin to explore the galaxy, the home planet simply runs out of resources before meaningful headway can be made. I think this is more of a slow-death kind of thing where maybe we get to do some exploration within the solar system and maybe a bit beyond for a while, but overpopulation, war, disease, famine, and whatever else causes us to realign our priorities from space exploration to merely sustaining life on our own planet. A civilization that had the foresight to know something like that was happening could theoretically, if they had the goal of galactic expansion from the start, avoid this situation, but the problem is that NO civilization has that kind of 10,000 year plan from the get-go, and they all sputter out right before they could have pulled it off. There's not a textbook on "how to succeed as a species" that gets handed out to a life form when it develops self-awareness, so following the natural progression, they all fail. the ability to extract resources necessary for galactic colonization from anywhere off-planet becomes viable too late in the game to save the species.

tl;dr - We're all gonna die, prolly. Thoughts?

Actual OP here.

I've posted in this thread a few times over the years (LOL?), and I pretty much agree with you. Life is probably kinda rare, and intelligent life is exceedingly rare. We really have no idea what other, exotic chemistry might sustain life. I like the idea that we "shouldn't assume we're special or unique," as an approach upheld by most astronomers, but we do keep finding star systems that are vastly different from our own. If our solar system is an oddball, then it stands to reason that life, as we know it, is also and oddball scenario. We might be the one-in-a-gazillion chance where life arises, and while it might be "common" in terms of the vastness of the universe, the odds of us contacting another intelligent species are probably pretty slim.

Like, what if the next closest intelligent species in the Andromeda Galaxy, or even worse, 2 galaxies away? We'll basically never know without some kind of inter-dimensional travel, and we don't know how to do that.

SO i got this new guy at work who is pretty obsessed with astrology, normally I wouldn't really care but he keeps projecting his assumptions on me because of my birthdate which I find pretty annoying I mean, he can believe whatever he want but leave me out of it

Now telling people they're wrong is generally going to create a shit atmosphere and i think quite a few of my coworkers would like astrology to be a real thing, so I want to set some traps. What are some tricky, good questions i can ask him that show he is just connecting dots because he likes to see them connected?

>TL;DR What are some questions to ask astrologists to show they're full of shit!?

Tell him you lied and your birthday is really a different date. It'll throw him off enough to at least leave you alone, or he'll start making silly hindsight-bias-assumptions about your "new" birthday. At which point, you can tell him you've been fucking with him the whole time and he's full of shit.
