Slightly off-topic I know, but I keep an eye on the Perseverance Mars Rover sites as well, as that is continuing to produce amazing images. I stumbled into a rabbit hole and landed upon this video which triggered "Hey, where did I recently see that name Perseverance? Oh yeah, Oatcake." Synchronicity? Anyway, you've likely seen it or similar, but a good primer on the rover.

Happy I found this thread. Usually spend my time on Reddit reading about space, Webb etc. , nice to see some of my fellow Stokies interested in this kind of subject also! Here's a pic of Jupiter I saw taken by JWST last week. (edit: best to click to image, didn't realise it would upload so small)

A daft question from me. All this stuff fascinates me but I just don’t really understand it 😂.
Is there a possibility/chance we are the most advanced life form in the universe.
I’ve heard all of the sounds etc we’ve received but just can’t really process it 😂

I’ve heard all of the sounds etc we’ve received but just can’t really process it 😂 It's a scary thought that we could be the most intelligent isn't it!? I'd probably guess we're not alone. It's an absolute mind melter to think about but it'd be amazing if we could detect something in my lifetime.

Either we are the only “intelligent” life in the universe, Or we are not. Either statement is mind blowing. And then you get to, Either we are the most intelligent life in the universe, Or we are not. Which is even more mind blowing

Or that there are countless other planets out there with life on them, many, many of which are way more advanced than we are, and some of them (Although I highly doubt this!) might even be more violent than we are... And for all we know they've already detected us & are heading our way!

I’ve heard all of the sounds etc we’ve received but just can’t really process it 😂 Consider it this way... There are on average between 200 to 300 SEXTILLION stars in the Universe, one sextillion written as a number is 1,000,000,000,000,000,000,000. About 10,000 stars, for every single grain of sand on Earth. Each of those stars, will have a solar system, with any number of planets rotating it just like ours. We're in what is called "The Goldie Locks Zone" , which is the perfect distance from our star, to create sustainable life, so there are potentially Sextillions of Earth like planets, rotating their stars, in the Goldie locks zone, possibly creating sustainable life, that we will probably never be able to observe. We can barely observe outside of our own Milky Way, which on it's own contains somewhere between 200 to 300 billion stars in itself. So in short, the probability that we are the only intelligent life in the universe is pretty damn slim...but we still don't know. Plus, the universe is continually expanding, getting further and further away from us, so the scary/sad thing is, there are things out there that we will never ever be able to see as they are gone forever. Their light is so far away from us, that it will never reach us again. So you have to think, what has been before, and what have we missed, what is still out there, but will become so far away, that even if we develop the technology, we will never be able to observe it. Its a fascinating, mind blowing subject, one that our brains can't even comprehend. The sad thing is, the human race will probably end up destroying the planet before we gain the technology to help us view outside of our Milky Way, if not us, then the Sun will burn itself out in the next 5 billion years anyway, so we have that to look forward to . This is a very good video to give you some perspective on how incredibly big the universe actually is, (what light reaches us that is), and how tiny we actually are. P.S. Don't lose any sleep tonight!

Something to consider is that, despite being an estimated 14billion odd years old, the universe has only just been born in universal timescales. It’s a newborn baby wailing for the first time.
It’s likely we’re incredibly early into the game in terms of advanced technological intelligence. Our star is relatively short lived (although some beliefs that our star type might be best for complex biology) but compared to red dwarfs, our star’s lifespan is probably analogous to comparing the lifespan of a human (red dwarfs) to the lifespan of a mayfly. (our “short-lived” sun)
I suspect there are other civilisations out there but, right now, they’re so widely distributed that detection probably won’t happen in our lifetimes.
Although, going against what I’ve just said, there have been a lot of signals detected that are very hard to explain naturally. But none have repeated yet. If one ever does it’ll be the greatest moment in human history.

If one ever does it’ll be the greatest moment in human history. It will be I agree. Maybe they're not repeated because they don't want anyone else to know they are there. We could be making a huge mistake sending out signals from Earth. Maybe other intelligent life forms know what is out there and want to stay hidden for very good reason. Or...they know were here, visit us all the time, and are observing us, just like we observe anything and everything. So many questions, not many answers

Like a ghostly hand reaching up. I would love the see Webb's view of Orion Nebula--it's pretty spread out arcsecond wise, so will probably take a long time to image and tile up. I'd also like some globular cluster images which I think would be extremely humbling.

Do these questions have an answer…….. in the beginning, there was an infinitely dense, tiny ball of matter. Then, 22 billion years ago it all went bang, giving rise to the atoms, molecules, stars and galaxies that form our universe we see today. Or at least, that's what we've been told. So the first question is where did this infinitely dense, tiny ball of matter exist? It must have been somewhere. Second question is how tiny was this ball of matter to turn into a universe 90 billion light years across and still expanding?

That's a great image, isn't it. And demonstrates nicely the effect of gravity. Those 'lumpy bits' are just 'stuck' on the outside by the effect of the small gravitational pull of the mass of the object itself, rather than originating from geological processes. Fascinating pic, a space Ferrero Roche!

If we live in a Multiverse, our universe is presumably a spawn or creation from one of those other universes. If we live in a simulation, we are just a bit of code (possibly a virus) which just keeps self replicating. I suppose it’s possible that somebody will do a ctrl-alt-del on us one day. And, if you are open to some of the beliefs being promoted by Musik in the Christianity thread, you may find a signpost towards your answer there. (The discussion has expanded well beyond the thread topic (much like the universe itself!)) oatcakefanzine.proboards.com/thread/306695/christianityThere is an explanation of an expanding universe contained within some of the theories around quantum mechanics but it’s been a while since I read it and I’m a bit hazy about the detail. Apart from that lot, I’m out of ideas. Do you have any ideas about it yourself?

Pretty sure you can't say matter, energy, time, etc. existed as we know it before the big bang. So it was simply just "something" science has yet to understand. You can probably just say in the beginning there was nothing and you'd be correct.

"Nothing" in terms of space implies that there has to be something for there to be nothing in it. What was that "something" in which an infinitely dense tiny ball of matter went bang in to start our universe? It can’t have been nothing or that tiny ball of matter wouldn’t have existed. Would it? As you say it’s all mind boggling and nobody seems to be able to explain it in layman’s terms. I even find the process of hitting Dimorphos, an orbiting piece of rock 160 meters long and 6.5 million miles away, pretty mind boggling tbh.

I think even that is confusing, because it's a slightly different acceptance of what nothing is! I get your definition, about their needing to be something for nothing to make sense, but you have to try (and it's brain-frying to do so!) to get your head around there being literally nothing: no time, no space and then that 'thing' that came into being creates time and space and also the 'nothing' that fits your definition! It's enough to make your brain hurt! I think the fundamental problem is that our brains don't allow us not to think of a 'before'...and you can't do that in this case!
