^Fascinating!! This metaphor was absolutely mind blowing.

"If the proton of a hydrogen atom was the size of the sun on this map, we would need 11 more of these maps to show the average distance to the electron."

Indeed! I love when it says that we're pathetically insignificant or miraculously important at the same time, considering the huge void that makes up 99,999......% of the universe with us and the other planets being the remaining 0,00......1% of matter.

Musk unveiled the latest Starship yesterday. I can't wait to see this thing hop in the coming months and eventually be mounted on top of a Super Heavy booster.

For sure. I don't remember the exact numbers, but by the time all is said and done, carbon fiber ends up costing about $200 per kilogram, whereas stainless steel only costs around $2.50 for the same amount. The stainless is also good for reentry too, which is kind of important I guess if you've got a few dozen people on board.

The real takeaway from all of that is we simply don't have a damn clue. We celebrate new theories about how it all works, but in the end they're all just conjecture based on things we know absolutely nothing about, and observations based on what little of the universe we can see, with no idea how much of it lies beyond. Truth be told, I'd put about as much stock in Homer's doughnut shaped universe as I would in these guys and their cosmic superstructure. In the meantime, the course of human knowledge pretty much remains the same as we continue to base our theories on premises that are unfounded to begin with.

Totally agree, but when I read stuff like that, it just makes me feel so small and unimportant. Which is true, but I only get that feeling when I think about the universe or look at the stars.

Since it landed in Gale Crater in 2012, the Curiosity rover has been studying the Martian surface beneath its wheels to learn more about the planet's history. But Curiosity also stuck its nose in the air for a big sniff to understand the Martian atmosphere.

So far, this sniffing has resulted in some findings that scientists are still trying to understand.
Earlier this year, the rover's tunable laser spectrometer, called SAM, which stands for Sample Analysis at Mars, detected the largest amount of methane ever measured during its mission.
SAM has also found that over time, oxygen behaves in a way that can't be explained by any chemical process scientists currently understand.

Interesting read overall.

I love taking these pics... from last week's full moon. I took this picture as I was leaving a concert in Denver. Was chatting wtih a girl and she's like wow the full moon is so nice! So I said, you want a better look? Since I had my concert camera on me, boom, in five seconds was showing her this:

Needless to say, we went to a bar afterwards

What type of camera do you have?

cramx3 · « **Reply #1557 on:** December 18, 2019, 01:36:46 PM »

Panasonic Lumix DS60. I use it for the optical zoom for concert videos which works great, but when I got the camera I was just trying to see if it could take a picture of the moon and somehow it takes really good ones handheld. It's like a $200 camera these days, nothing high end at all. I often sneak in video of the moon into my concert videos if it's part of the night, which it was and I included it in my Slackers video.

Well, maybe it already did 1000 years ago and we're still seeing the light that had traveled since

I randomly stumbled on a YT vid that explained that Betelgeuse is far enough to not pose any problems for us when it goes boom. Otherwise we would have all been royally screwed.

Yes, we are at a safe distant where the radiation will just give us a very nice show in the night sky, even to the naked eye. Also, I just saw this article and the findings are weird. The dimming seems to be happening only in part of the star, not all around.

If that were the case, then we (humans) would've already seen it by now since it is somewhere between 500 & 600 lightyears away. The dimming shown in the photographs already happened that long ago. It could be a prelude to supernova. I find this very exciting because I've always been fascinated and very interested in this star.

I imaged from my Manorville NY USA Backyard. The International Space Stationwas was at the Max Pass of 84° / Dragon CRS-20 and more Spacecraft are docked to it and in my image and short video.

SpaceX is ready to make space history with its first astronaut launch for NASA next week.

No showstoppers were found during a crucial flight readiness review (FRR) for SpaceX's Demo-2 mission, keeping the company's first-ever crewed flight on track for a May 27 liftoff, NASA officials announced today (May 22).

"The Flight Readiness Review has concluded, and NASA’s SpaceX Demo-2 mission is cleared to proceed toward liftoff on the first crewed flight of the agency’s Commercial Crew Program," NASA officials wrote in an update today.

Yes, finally!

Highest elevation would be my guess. The chunk of land their on is only 9' ASL, and it's the highest point for miles. The houses are only 4 or 5. Outside of that plateau you're mostly looking at sea level.
