This animation shows a supercomputer simulation of a galaxy like the Milky Way and its invisible dark matter halo. We zoom in to the galaxy and can see knots of dark matter where we would expect to see many satellite galaxies, but they dont exist in the real Universe. Thats the missing satellite problem.

Space Ping!
If you didn’t know how much there was in the first place, how would you know half of it was missing?.............
Still awaiting explanation of the Great Attractor, and what it is.
That damn Glowbull Warming is up to it’s nefarious ways again.
wonder how much is in Moochele’s trunk?
Are they going to now have to doublecheck ALL their findings using common core math?
I like dark chocolate but not Milky Way. Snickers is better.
Aahh man... I was hoping to get a ton of this Unobtainium to play with on my forge this weekend...
I’m offended.
How will I ever get my fair share of dark matter now?
This sucks, it’s completely unfair.
Think I’ll take down the convenience store down the block. I’ll wait til it’s dark. They can suck on their dark matter. Yeah.
They probably haven't factored in that Negative Energy barrier ....
Ya but, have they looked in ALL the universes? Sometimes you can find missing matter in the last place you look.
That's racist!!
Five million billion kilometers? Holy crap.
I suppose I’ll have to stop using so much!
I know where all the dark matter and dark energy went.
If it’s true that time travel is possible, then, it’s also true that, all matter and energy from any particular instance in time, have all gone into the past. The past and the present interact, and the present feels the effect of the matter and energy that have “passed on”.
The most current instance of the “past energy and matter”, can be called the “most recent instance of the past universe”, and that instance will be the most felt in measurements. The instance before, will also have an effect on measurements, but not as great as the most recent. The third instance before the current instance of the universe, will also have an effect on the current universe... and so on... up to the very first instance of the universe. All of those instances comprise the “universes”. All of those universes (or instances of the universe), all interact, and they do exist, and it’s why it might be possible to travel to the past. We won’t be able to travel into the future, since, no instances of the universe have “passed” into future times. We can’t interact with what hasn’t already occurred.
They forgot to look in my basement!
The Universe is racist.
