Astronomers think there should be 5 times as much dark matter as ordinary matter – a shadow universe that makes up most of the mass in the universe. But after decades of trying, no experiments have found any trace of dark matter – except one.

- A simpletons take: Since dark energy is closely associated with blackholes, why don't we just observe that alongside the sodim iodide experiment??? 🤔
Just wow 👏
Your June and November dates correlate directly with the Taurid meteor stream.
I would think the massive weight and ludicrous speed of the spinning black hole at the center of a galaxy like that, would in-turn cause everything else within it's reach to spin and accelerate over time.
Could dark matter be nonexistent, but instead these motions to be gravity's another function somewhat?
nice now make a DMR
I predict we deflected omauamua because the movement of our planets around the sun creates an "dark matter turbulence"
goated thumbnail change
Well explained video essay on interesting physical problems:exists
My brain: Hehe he pronounced German word funny
Not dark matter but A magnetic gravity property
What if dark matter concept not real and our understanding isn’t correct about dark matter and big bang
whoa, be careful, we don't want our dark matter to fly out of the screen to poke our delicate eyes, do we?
The Highlight of this video was the way you pronounced "Dunkle Materie". 😂😂 Das war vieles, aber nicht Deutsch lmao
Are we absolutely sure D-Matter isn't Neutrinos? Your description sounded VERY much like a neutrino, is all I'm saying...and, well, Ockham's Razor, man!
Is anyone doing any serious work into this? Maybe some variant form, like a charged-neutrino, or perhaps a kind of isotropic-decay process going on for these little critters that we just haven't seen yet... Absence of Evidence isn't the same as Evidence of Absence, after all...
What if it isn't actually dark matter and instead is an energy wave like some kind of electrical current? Could it be that dark matter doesn't actually exist and that it is something completely different?
You know I wonder if this guy himself actually understands it all also. Like how much approximate knowledge on many things can you have?
Don't get me wrong he is awesome, just pointing out something I have been wondering about.
Why is Jan Hendrik Oort forgotten??? 1932 he observed the bias in andromeda's velocity curve, before Zwicky!
Dark matter matters.
