To infinity and beyond

That's roughly how I understand it as well. Once all the energy runs out, we're left with a cold universe. As humans we feel the need to think of everything having a beginning and an end, but maybe some things never end, they just keep going even when nothing is really happening anymore. In this subject I think it's helpful to try and put aside what we consider as normal when trying to theorise.

Worth a look.

The most detailed map of the universe to date.
The fascinating thing about that is that galaxy super clusters shouldn't really exist. That's why we know that dark matter exists. Galaxies all have an escape velocity that would see them escape the gravitational pull of the other galaxies. Without dark matter every galaxy exceeds that velocity.

It works by copying and pasting if that helps.
Truly mind blowing the size of universe.
Not really a huge interest of mine buto it is fascinating.
My tuppence worth no danger there isn't life out there somewhere even if it is just some forms of bacteria or something still think there will some sort of evolved life though.
I agree. I don't think intelligent life is widespread, but bacterial life will be present on millions if not billions of worlds.
One idea I've been kicking around my head for a wee while is concerning evolution. Evolution on our planet started with bacteria evolving into other more complex life and eventually on to what we have now, bit given that we are almost identical in our make up to every other living being and more importantly our chemical composition is very similar to that of rocks. Is it possible that somewhere in the universe a planet has evolved to have consciousness? I know it sounds ridiculous, but when you think of the circumstances that led to humans it seems more plausible. The chances of us evolving from the first bacterial life must be billions and billions to one.
I really think on this subject absolutely anything is possible and probably is given the sheer size of the universe and the possibility that our universe is probably just one amongst an infinite number of other universes.
Another thought that I play with is where are we as humans on the size spectrum? We know that there are things that are infinitely bigger and smaller than we are, but are we near the middle of the spectrum or closer to the biggest or smallest thing?
Us : Tiniest quarks within an atom (or anything out there that is smaller)
vs
Us : Largest star in the universe(s) (or anything out there that is bigger)
Excellent topic by the way, OP. Have been reading with interest. The universe, in it's infiniteness, is fascinating. It saddens me that I'm confident we won't come close to understanding even a tiny % of it all before I die. I'm 99.9% certain that there is life, intelligent at that, out there - just based on probability due to the size of it all. I don't know how likely we are to ever encounter them though, given the billions of years the universe has existed for and the billions to surely come, we'll only likely be here to meet them for a small scope of time in that timeline.
A similar question to your one on size is where we fall on the scale of intelligence/evolution/industrialisation compared to everything else out there.
Hopefully before I die we find there really are people like groot and star-Lord out there.
Keep posting though guys very enjoyable and interesting reading 👍.
Most guesses at how much intelligent life out there are based on the Drake formula. But the Drake formula uses many unknown components and depending on these components you will get an answer of somewhere between 100's of millions of possible planets that will or have produced intelligent life and less than 1 but still more than 0. Now bearing in mind the formula is only used to calculate the likelihood of intelligent life in our Galaxy and the universe is infinite then the actual number of planets that will or have produced intelligent ET life is also infinite and that based on using the most pessimistic components in the calculation. The theory has its flaws, none more than the so called Fermi (I think) paradox but it's the best we've got and I like to think that even the most pessimistic outlook still guarantees swotty ETS.
There's a new documentary series starting on Sunday night called Strip the universe. It's on the discovery channel, the trailer looked quite good.
The Mars Perseverance rover is due to land next week. It’s got a mini helicopter on it that will be able to explore more than ever before. Fingers crossed that everything goes well.

I've got Software that allows me to preplan my drone's route prior to it taking off by using way points. I'm guessing the first flight will be basically just up and down to get a look at the terrain and then use that information to plan further flights. All guesswork on my part of course.
