I recently heard from Dr Tyson that all galaxies (or at least the vast majority, he wasn't being super precise in this presentation) we have checked appear to have black holes in their centers. That got me wondering why that would be, and this galaxy-scale accretion disk is the best idea I've got. But I feel like I would have heard of that before if the answer was that simple, and that doesn't really fit with the way that black holes are formed themselves. So what's the deal?
Since many elliptical galaxies have stars not orbit on a single plane, but matter tends to look for a plane such as a 3D area of gas coalescing into a star-forming disk, wouldn't it be the case that elliptical galaxies will eventually form non star-forming disk-shaped galaxies? (in billions of years, since there wouldn't be enough time now for an elliptical galaxy to be formed and for angular momentum to be transferred in this way throughout the entire galaxy)
I'm not going to claim anything just curious, but I have been told galaxys have black holes in the center. But why are solar systems and all matter orbit the center in a disk rotation? Why do galaxys never take a shape of a sphere?
Anytime you see a map of the galaxy it's usually a flat disk on a grid or something. You generally don't see any overlapping solar systems or hyperspace lanes, and hyperspace lanes don't seem to go "up" or "down". They're represented like roads or rivers in the real world. But that isn't how galaxies work. Realistically you should have many solar systems overlapping on the same grid coordinates but at different levels, and you would need hyperspace lanes at different levels to connect them. A map of a galaxy would have to be represented 3 dimensionally. I know there are limitations to representing a galaxy map on a flat page, but I was curious if the EU acknowledges this?
Ok so I found my favorite child hood game (super Mario galaxy) so i wanted to play it
Every thing was going ok until..
"disc could not be read"
I was use to this due to playing Wii/ Wii-u games so much so I went and checked. ran water on it. dryed it (with a paper towel). put it back in then nothing worked..
So I went to google. tried what nintendo.coms help section. tried it nothing worked.
So Is My Disc Just Broke? Or is There something else I could try.
i don't know if super Mario galaxy is on sale anymore for the switch so.
help me please :)
Platform: PC, Windows 3.1/95
Genre: ...2D platform? Maybe 2D puzzle platform?
Estimated year of release: 1994-1997 (It was on a 1997 disk, so sometime during that year or most recent previous years)
Graphic art style: Lode Runner/Destructivator in map design, art style I couldn't find a close enough reference to...much better quality than Lode Runner (1983), but definitely no Lode Runner Legacy. Very Windows95 as far as graphics goes.
Notable characters: the enemies were yellow stubby dinosaurs. Super stubby dinosaurs walking on hind legs. BIG chompers. Little arms. Think Akumon, but even shorter legs. If your character fell off a platform, you'd fall with an umbrella to slow the fall. If a dinosaur fell, they'd flip head-first over and over until they hit the ground.
Notable gameplay mechanics:
The object was to get all the...cheese? It made a very obnoxious and obvious "chomp" or "gulp" sound when it was consumed, similar to the sound effect in a cartoon. Much like Lode Runner, it was plaforms among platforms with interconnecting ladders.
The coolest part in my opinion (as a kid anyway) was that you had an option to change the textures of the map in-game as you selected the level. You could change the background, the bricks, and I think the cheese? I remember it wasn't just BMP files either, because there was one texture that was a GIF, kind of psychedelic colors. You might have been able to change the sounds or music too, but that could have also just been a BGM/SFX toggle.
There were probably close to 30 different levels, which you could select at any time. The copy we had wasn't the full game, so you could play the first 12 levels or so, and the rest were demos you could watch where the AI would fail to play that map for you.
Other details: this was a shareware game on a Galaxy of Games 3 disk my uncle had when I was a kid.
There might have also been time travel as part of the lore, but I can't remember 100%. Something's telling me time travel or a different planet though. Let this be optional information.
I'm at my wit's end with this one, can't find a screenshot of it anywhere no matter what kind of key words I put in, can't find a reference to it, most of the online numbered "copies" of Galaxy of Games is only 1 and 2, and the only copy I could find of Galaxy of Games 3 was a corrupt ISO on Archive.
Whoever can find this will honestly be pushing me one step closer to reliving the best memories I had
... keep reading on reddit ➡I know that's not the best way to ask that question, but hear me out... I got to thinking about it from this post: https://www.reddit.com/r/interestingasfuck/comments/na7jur/if_the_andromeda_galaxy_was_bright_enough_to_see/
My question is since andromeda is so wide, 220 million light years according to other posts. why is it not widely askew. Like The leading edge is about 2.5 million light years away which means it reaches our eyes and telescopes first by more than 217 million light years compared to the back edge. Which means that the front position is completely different then what is on the back edge by the time the light gets to us. This would be true to nearly any sipral galaxy dependent on its orientation to us.
Due to the vastly different time scales the light has to travel, how does it look so uniform rather than it being an oblong smudge?
Hi, I am looking for this paper. I hope someone can help me out with this. Thanks in advance!
Spiral morphology in an intensely star-forming disk galaxy more than 12 billion years ago
URL: https://science.sciencemag.org/content/early/2021/05/19/science.abe9680/tab-pdf
Paper: https://arxiv.org/abs/2106.10283
Context: Continuing the saga of DF2, this paper looks for signs of tidal stripping as a way to form an ultra-diffuse galaxy with low dark matter content (as was done for its neighbor, DF4). Using deep Hubble imaging to the far out regions of DF2, they find no signs of stripping or disruption by its host galaxy. They do however find a stellar component consistent with a low-inclination disk in the galaxy. If this is a true disk component of the galaxy, the previous dynamical mass estimates underestimate the dark matter content. With some rough numbers for the rotation, it turns out the dark matter content could be more in line with typical dwarf galaxies.
Is there any way to sort your library by the size of the game install? If not can that feature be added?
Timestamps - Note 9 | Screen Scratch | Bezel Scratch
Hi all,
PS5 - Relisting the PS5 as the local sale fell through last time. I am giving the highest priority to local deals ZIP CODE IS 17059 as I do not want to ship this thing, it's big, it's expensive, and the USPS has been having issues. I have the original box, and included are 2 games - Demon's Souls and Godfall, both not pictured but have cases, etc. Works fine, no issues with the console, just don't play it much anymore. I am asking $570 and I will not sell without selling the games under any circumstances. PENDING SALE SOLD
Note 9 128gb- I can chuck a charger in the package, just not pictured. It's got a small surface scratch as shown on the screen, but when I run my fingernail over it I can barely feel it. It has no impact of the usability of the device. There's also a scratch on the corner, as shown above. There are some surface scratches on the back, but nothing is shattered or anything. It does include the stylus as well. I just upgraded, and have no need for this phone. It was used on AT&T and Cricket with no issues. Has been wiped and whatnot. Asking $160 shipped to the continental 48 Sold
I understand that by default, the Galaxy S10 uses file-based encryption. I've disabled that when rooting. But is there some way to institute full-disk encryption using secure startup on boot?
