The Quest for Dark Matter: Exploring its Origins and Implications for the Universe

The thing is, we're measuring the effects of gravity, not gravity itself*. Based on the effects we're observing, there appears to be a deficit of matter. So, it could either be due to the presence of unseen matter (dark matter), OR gravity may not function exactly as we currently understand it.

* We're actually starting to be able to measure gravitational waves, but that has nothing to do with this.

[Fairlyexperiencedgentilecrypto]

What matters is that in reality nothing we think scientifically, mathematically even from the most brilliant minds would end up being even .00001% what actually exists in the universe. We have no idea what created the universe, we have no who or what created it and on a galactic scale nothing any human thinks is gonna be how it actually is in space

[dusanbajic]

How is the collective gravity of the universe measured?

[dannyoceanss]

"Sir this is starbucks do you want your dark chocolate mocha or not?"

[TheWayOfRespectAndKindness]

When the tiniest misunderstanding is blown up to galactic scales…

Long story short, the various gravity components that affect gravity is radiation density, matter density, curvature density and the cosmological constant. The gravity that created the structure we see in the sky SHOULD be a caused by a matter component, and that is why we imply that 85% of what’s causing that is matter, which is unknown to us because it doesn’t interact with light so we can’t see, and it hardly interacts with normal matter except gravitationally. Hence we call it “dark matter” because it SHOULD be matter, judging by the effects, but it’s almost invisible to us. Not just in our eyes but in measurements. It’s only effect we can measure and imply things about it is its gravity. There’s plenty of evidence that it’s matter, just not the periodic table kind of matter. Not made up by atoms.

The cosmological constant part, which creates gravity such that it pushes the Universe to accelerate in size, is a candidate for “dark energy”. Energy which we do not know the form of. But the gravity induced by this has entirely different effects than the matter one. That is why we can say for certain that the dark energy part, is not additional matter.

[lastchance]

We have no idea what space even is. It may be that space itself is a mountain range of hills and valleys that is responsible for both the gravity gradients and the matter densities that migrated there. They thought they knew...and shoved it down our throats for the past 100 years, but they don't know Jack!

[stonesinmyblood]

Gravity doesn’t exist without momentum or movement.

[johnrobinson]

'Matter' is an assumption.
We OBSERVE that gravity doesn't follow the expected rules.
There may well be no additional matter or energy at all.
There is precedent for this.

[CptApplestrudl]

Its basically like when they found Neptune by reverse engineering the movements of the other planets to figure out where Neptune shoudl be...except in the case of Dark matter, there's no Neptune apparently.

[danieltill]

Perhaps as we are looking back in time the average mass was only 15% due to inflation?

[ZaaaZ]

Maybe gravity is not what we think it is..😮

[christopherkettler]

I thought all galaxies we're hooked to the gravity of super massive black holes so what holds galaxies together

[terrydaniels]

Understand it is a measurement that needs a new identity and future research Till they find out dark matter

[jioct]

what do u mean by origin? do u mean it is not bubbled in something like our gravity is sourced from the spend of our Earth,

[thlevelweb]

Or "we don't know what is going on so we need to make up a concept so our equations work."

[jeannytse]

Dark matter is just the part of the universe that has not been measured

[Goodengelt]

Approved for inclusion in lessons starting aged 10 once in each class with a physics component per school year

[Ai-hedp]

We measured the collective gravity of the universe or galaxy?...both are funny but the universe would be hilarious.

[ttk]

"Dark matter/gravity" really look like a vale someone put on the simulation so it doenst fall apart and "dark energy" the vale they put to Spice things up
