when a neutrino strikes Xenon, it imparts a VERY specific amount of energy to it and that has to be shed via a photon. those photons only exist at specific frequencies, so its a finger print. A wimp, if they exist and interact the same way, would have a whole bunch more energy in it do to its massive size and high kinetic energy, is should make a VERY bright signal if not be so energetic as to cause the photon to create subatomic particles that would then decay and give off a big field of photons. we can detect all those photons and add up the energy from them all to figure out what the original particles' properties were. we do that with cosmic rays hitting the atmosphere.

That was simply amazing. Breathtaking and informative. Thank you.

The discovery of you channel happens to be one of the best things to occur me during this year. Thanks for your effort.

Here's a couple observations and questions to go alongside them: Gravity is commonly known as an acceleration towards a body of matter. We know already that space time stretches and shrinks depending on the amount of matter (or more generally, energy) contained within it, and in turn, affects time (which to an outside observer also affects speed). This begs the question, how would it work the other way around? Would inducing a stretch in space time (such as the expansion of the universe) across a large enough space be able to affect the gravity an object experiences relative to the un-stretched space (that which is closer to the center of gravity)? This is not to say that it would directly increase the effect of gravity, instead it would be as though the matter were moved closer to the center in time rather than space. Like increasing the rate at which you experience gravity, rather than increasing gravity itself.

@sunRay04

2 жыл бұрын

In theories like the big rip, where space keeps on stretching faster, it would make sence that objects would still output the same amount of gravity. Considering that dark energy is not gravity, i think the answer to your question would be a no.

@@sunRay04 Nice point. In that case, rather than directly influencing gravity, it would be an emergent property of the expansion? Like someone on a boat losing grip of their anchor due to the waves (although the expansion does not involve normal forces, probably).

As rarely as we detect dark matter, I become a fan of a channel. This is one of those moments. Hope you'll get a wider audience!

So what I'm getting from this is that dark matter is the packing peanuts of the package (universe) while normal matter is the thing you ordered. The peanuts affect the ordered item, but they are basically junk that doesn't do anything else or have any other value. Or maybe I'm just confused, which is most likely the case.

Ok, that last part about Dark Matter being a patch genuinely scares me, and not a lot of psychological things do that. The Simulation theory is something that's been done to death that I'm not concerned whether it's real or not. From my perspective it doesn't matter. But Dark Matter as a "patch" is utterly terrifying, because now it presumes the Simulation isn't hands off. Those running the simulation can and have tinkered with the simulation as they need to, or as they see fit.

I feel like scientists might be jumping the gun on dark matter. Like with the example of the speeds of stars in a galaxy "indicating dark matter", I would say it comes down to occam's razor. It's far more likely that our methods of observing galaxies are just flawed in some way, or that our expected condition of those galaxies is actually inaccurate under the "scientifically agreed-upon rules" of normal matter. Dark matter just seems like a manmade concept to perfectly plug the holes in our physical model of the universe.

Imo, darkmatter seems more like a bonus effect or harmonic of another force. whos to say that light doesn't have different properties at the galactic scale? I've been thinking of galaxies as clouds that are centered around the force of gravity but are held together by electromagnetic fields like how poking a lump of plasma affects the structure of its entire mass

this makes me wonder though. if all "things" in the universe are excitations in a field, what makes them persist through time? what force/energy/weirdness is responsible for constancy through time?

My response was that no explanation of that form can be a satisfactory explanation for why physics continues to be how it is, and so there can’t be an answer that satisfies the question as asked. I suppose they did list “weirdness” as an alternative to “force” or “energy”, but I still got the impression that they meant for this “weirdness” to be a physical thing, not something metaphysical or theological.

I have often thought about the universe as a simulation, but this gave me another angle. Before, I always assumed that if the universe was a simulation, we were the subjects. Perhaps our ancestors or some other alien race wanted to observe something about the past. However, it could just as well be a physics simulation, meant for galaxy-scale observations. We may only be an unintended consequence of an unnecessarily high fidelity universe sandbox.

There's a new theory going around that information actually has it's own mass- and that what we observe as dark matter is just the mass of all the information in the universe.

I honestly thought we were talking about Kirby

Thanks to this Video, I can safely say I have forgotten more about dark matter than a lot of people know.

You forgot to add it is weak to crystals and can possess penguins.

I took a Cambridge Math graduate level degree 45 yrs ago. I got intrigued by these concepts when bedridden with long term illness some 15 years ago, and I whiled away some of this my time by deriving the simple orbital mechanics implied by the galaxy rotational profiles. This is quite easy to derive that using basic Newtonian gravity mechanics, and this leads to the conclusion that only a small % of the mass must be subject to the normal mechanisms for energy shedding (electromagnetic and strong forces) and thus decay/collapse into the dominantly 2D visible disc structure found in non-elliptic galaxies; you need 90+% of mass to be DM large immune to such collapse mechanisms. What is rarely discuss is that you still get angular momentum coupling between the visible and dark matter because of gravitational sling shot coupling as the DM orbits cross the visible galactic plane, and this flattens the otherwise spherical distribution of the DM. For the same reason it is nearly impossible for DM to orbitally decay into black holes.

Amazing! But in 9:40 and 10:17 isn't electromagnetism stronger than the weak force?

Nice

no way the villain from Kirby is real

my blender sense is tingling you can tell when youve used blender too much when you recognize the procedural textures from it

This video only considers the galaxy rotation observation, not all the other evidence. But a simpler and testable theory might be a modification of gravity that allows all the stars to attract each other more than the center of gravity of the galaxy. Then the outer stars would be pulled along more than the ones nearer the center. The advantage would be that no new particles have to be found, especially particles that cannot be found due to the difficulty of detecting them. The disadvantage is that some way of proving the adjustment to gravity would have to be found. Just my opinion!

I think "dark matter" isn't matter, but instead the invariant mass associated with the system of two photons traveling in different directions. The mass would be in frame where total momentum is zero. One photon is massless but two is massive if they're not going the same direction.

Thank you.. really.

Dark matter is a placeholder name for a theory's dead end. A way to keep funding and validation alive, telling us they need it to solve the 'crisis' in cosmology the theory creates. The other term for crisis in this instance is DEAD END.

The start of the video was clear enough; There appears to be an anomaly better the estimates of 'speeds' based on the Doppler measurements. Does the calculation take into account the distribution of the mass in the galaxy? If the model models the motion of the outer objects by using center of mass of the galaxy to model a 2 body simplification, then that could account for the discrepancy. Does the calculation take into account electric charge? I never hear any mention of charge when it comes to astronomical motion. There is a discontinuity in the video around the 3 minute mark where you jumped to 'dark matter particle'. Where did that come from? Isn't that just speculation?

How would these proposed options of dark matter interact with the gravity of a black hole?
