My own explanation of "Dark matter" is just the stuff we didnt know about yet. Take a look at the periodic table, from the 80's, and the post 2000... Up to date, over a 30 yrs spread, there are almost half-again the number of items on that table. Some of them are a lot heavier than the others in mass. How can you predict the mass of existing matter in the universe until you know how the body is composed, how many elements of heavy matter, and how dense it is in the first place. As in, the single quote that answers it all, "There are more things we dont know we dont know than there are things we know we dont know", as in, there is an awful lot we dont know. Therefore, there are things out there that maybe dont adhere to the visible light spectrum or even are dark to radio telescopy, that we aint seen yet. As for missing matter, we only JUST discovered to use the drop in light from distant stars to work out there are planets revolving around it. May I ask, what is the length in years it takes for the outer planets of our own universe to revolve around the sun?.. Unless you are watching every single sun for well over 10 yrs, you cant even be sure you have spotted every single planet revolving around that star. And thats something we only JUST got started on. I dont hold with "Missing matter" much other than there is a LOT we dont know we dont know, and time will tell, and I suggest that we will spot all of it eventually How long you got?.. The problem with many of those newer elements on the periodic table is that they don't naturally occur in nature. They are man made by slamming a bunch of parts of atoms together at high speed and then they only last a few millionths of a second, if even that long. Of course, you never know what may be lurking where the sun doesn't shine. Or where the sun DOES shine, but only on the outside. The heart of the sun is the hearth of the universes forges, and in the making of light, there are some weird and exotic particles smashing about inside a sun... And on the super-heavy gas giants, the super-sized stars, "who knows" what may exist, even for a short time, with that much energy available?..

I didn't realize it, but after 5 years, our Curiosity Mars Rover is still running around Mars doing it's "thing." Still mostly operational, that's pretty impressive. How many times have you had your car serviced in the last 5 years? Other than the wheels getting a little worn, it's still going strong. www.space.com/35992-curiosity-documentary-details-mars-science.html

I'll have to check Amazon to stream it.

[and why the newer ones are a pile of crud these days...]

If we presume that our own universe is for example a balloon, still expanding, but a balloon, who is to say that this is the only balloon in the party.
Just because light hasn't travelled that far yet is not conclusive evidence that beyond the borders of our own universe there are not many more out there.
I totally agree with the hypothesis that there are more universes out there.

What I find interesting is how we pretend we understand this stuff, when in fact, we don't have a clue.

I agree. - specifically referring to the people who come up with a theory that is not demonstrable, and refer to it in terms of "we know ___________" I suspect that is usually an artifact of things being translated to media sound bite, but it is still amusing.

I actually do understand this multi-verse thing.
We sort of understand that the universe we know is from one big bang... over here... The idea is that way way out beyond the edges of our own universe in a space of its own, another universe sprang up, just like ours. This latest theory is perhaps that the two "balloons" of those two universes have started to expand so fat they have started to expand into each others space. I had predicted that a while back, now they found proof...
I am using the balloon analogy, because it fits... if our own universe was a balloon floating about in space and it collided with another?.. The hardest thing is to visualise all of this, so I am giving an easy visualisation with the balloons.
Who is to say that in infinity of space this cant happen. Because if our own universe was started by some random spark in nothing, its only feasible that that must be repeatable at some point.
Is it demonstrateable?.. why yes it is, however, I need a space the size of a universe times about a thousand, and a couple of random sparks big enough to start a universe in, if you can just tell me where you want to stand, I can make sure its facing your way?.
Oh, and you may need a millennium or two for the light to get to you, so dont go anywhere for a while.
Can it be demonstrated, yes it can, you are part of the demonstration. All we have to hope is that we aint just part of some pan-galactic kids science experiment now...
The space around us doesnt stop at the edge of our universe, there is no "Brick wall" that signifies the edge of reality, there is only what we know "So Far", and we are always learning, so learn some more, and expect that just like galaxies are one beyond another, so are universes. This is more than one, we just didnt get to detect it yet. The same way a thousand years ago, Mankind couldn't see past the galaxy, because they didnt have modern telescopes. The best is yet to come, our knowledge is expanding.
Just dont expect a travel plan to go visit for a few years is all....

Nothing to it. A lot of space, a little Spark and poof.
Like I said, not a clue.

Infinity, I dont understand whats so difficult to understand there.?.. its infinity, its infinite. "Anything can happen", and most often, usually does.

But knowing it can happen still doesn't explain how or why it happens. In the vast nothingness of infinity, a singularity appears. The singularity then explodes and expands into the universe as we know it. Yep, that explains it. Not a clue.

so... it looks like this makes the area around the earth where sunspot interference is filtered out a bit bigger, and manned space missions are exposed to a little bit less high energy "space radiation" but a rogue asteroid or the death star wouldn't be affected at all. go Humans. here is NASA's own press release about it: www.nasa.gov/feature/goddard/2017/nasas-van-allen-probes-spot-man-made-barrier-shrouding-earthwhich is a bit less self congratulatory. more along the lines of "if we get a stellar event which causes radio interference, we can use less obnoxious radio interference to interfere with it."

This article is really interesting to me. I'm going to link the whole story, but it's summed up very well in this diagram. Basically, scientists thought the moon was formed one way, but based off of tests made on moon rocks, things ain't as they seem The Moon's Origin Story Is in Crisis
