I think this may be my favorite Sixty Symbols so far. The first 3 minutes of the vid are such a perfect illumination of one of the fundamental attitudes of science. As Meghan continues at 10:47, the layman's skepticism "wait, did you just make that up?" actually leads to a great illustration of the scientific method. No, they didn't just "make it up", but expressing such skepticism is an integral part of learning. Top stuff.

We saw that there was a dichotomy between dark matter theory and general relativity. I have wishfully hypothesized that astronomical distances might not be as large as indicated by red shifts and that distance itself is a function of gravitational field strength. I'm not enough of a physicist to do the maths, but wouldn't it be nice to discover that the stars are indeed much closer than we thought.

They do maintain their velocity - the problem is that the stars on the outside of the galaxies move at the same rate as the stars on the inside. So they should be flying off away from the galaxy, yet they don't. In our solar system, Mercury moves at about 48 km/s, while Neptune only moves at about 5 1/2 km/s. On a galactic scale, they do not see the same reduction in speed with an increase in distance, so the outer stars should be "flying off" into deep space. Hence dark matter is needed.

@P00P0STER0US its more or less done for editing. The camera operator needs to sense the more important points and high lite them with a closer frame. When the final video is made, it is important to have these options to work with the various arguments being made. You don't see this in Live TV because, as you noticed it would be distracting, however is recorded programs, each scene has many takes with various angles and compositions for the editor to choose from.

The outer stars don't really slow down because as they lose energy they fall in, and then gain energy which spits them back to their proper orbits. It happens with all the planets in the solar system, plus the moon, and (theoretically) to electrons orbiting a nucleus. The moon comes closer and goes further away and never really gets much closer to the earth, and has done for a very long time already. No orbit is perfectly spherical, not even an electrons at the speed of light(or close to).

Yes you are correct, I was mistaken and wrote the wrong term. I was confusing the term Hadron, which is above Baryons in particle nomenclature hierarchy because Hadron's are Baryons (3 quark composite particles) AND Mesons (2 quark composite particles). My bad. What I meant to say is that FERMIONs are all the matter particles in the standard model. Aka everywhere I said Baryon I meant to say Fermion and vice versa. I was pretty fucking high on BHO and some DANK Kush when I wrote that.

Apart from the outright loonies in the comments, who are in the wrong place, there is still a huge misunderstanding going on, even among the (slightly) more rational. Don't go around discussing daft things like how it became dark " _is it possible that the electrical charge between the nucleus and electron fizzles out, which causes the particles to go dark_ " this sort of thing. 'Dark matter' is just a name given because they can't see it and haven't detected it yet ( if it exists) not because it *_really_* is dark! They could have called it anything, you need some name when referring to a concept.

I was left wondering how come the models we have of the birth of the Universe don't tell us about dark matter and energy being formed (and thus what it is and how to look for it). I guess it works the other way round, we need to know the properties of something before we start working out explanations of how it came to be. But then again, if something so pervasive as dark matter is real and yet missing from the current origin models, I'd expect them to make all kinds of false predictions.

Astronomers look at the Cosmological question "out there" of how the universe fits together, and Physicists are at the reciprocal end of scale. In between, chemistry and mathematics deal with functionality of the connection. So if the Cosmological structures, Periodic table of elements plus the Particle zoo demonstrate the mathematical distribution of the kind of reciprocal relationships that Dirc was interested in, would that be the Dark Matter research Dr Gray mentioned?

So a halo of dark matter in galaxies causes the stars to speed up. But there must also be a halo of dark matter around the solar system - there's 10 times as much of it as ordinary matter. Why does it not affect the outer planets. Why isn't Neptune going as fast as Mercury?
@hjembrentkent61818 жыл бұрын
It doesn't affect the orbits of planet much because the density of dark matter is very low compared to the matter in the solar system, it's spread out over a much larger volume than the matter in the galaxy. Because it doesn't emit light it doesn't have friction, so the particles stayed in very large orbits while the normal matter compacted together

+Derederi WHY doesnt it react with other particles? The universe is pumping lots of radiaton through the stuff, so it should be "getting some energy" from that IF it was a "simple" particle. Also: "absolute zero" only really applies to "matter particles" [=atoms] and "energy particles" do not care about irrelevant stuff like temperature. Oh and "temperature = movement" is a thing AND the universe is constantly expanding, so "absolute zero" can't really be a thing, because dark matter expands with the universe and has a speed.

No it's dark because it hasn't contracted together like the normal matter has. Regular atoms emit light, they collide, so they have friction. Dark matter doesn't have that, it stays out beyond the visible galaxy in large orbits. It's transparent to normal matter, and more importantly it's transparent to itself. It only interacts through gravity and what's called the weak interaction probably, similar to a neutrino, only much heavier.
