Quarks: They Make up (a lot of) The Universe
Hello! I'm back!!
In this video I’m going to look at Quarks, and their relationship with the matter of the universe.
Ok so lets start off with matter. This is the stuff that makes up much of the visible universe. Matter is made from atoms, and atoms are made from protons and neutrons collected in the nucleus, and electrons in a sort of cloud around the nucleus. If we look more closely at the protons and neutrons, we find that they are in turn made up of even more fundamental particles called quarks, but what are quarks.
Quarks are part of the standard model of particle physics, which we can see here, and there are 6 types of quark, and we call the different types flavours. The 6 flavours are, Up, down, top, bottom, strange and charm. Up, down and strange are grouped together as they are lighter, and the top, bottom and charm are grouped together as they are heavier.

The universe is a wondrous place, but what makes it all tick. What holds it all together and stops everything from just flying off into… well space. In this video I’m going to have a beginners guide look at the fundamental forces that hold the universe together. Let’s find out more. There are a number of fundamental forces, or interactions as they tend to be called, and I’m going to take each o...
Einstein and Mercury: How the Orbit of Mercury Proved Einstein was Right
Переглядів 15 тис.Рік тому
The orbit of the planet Mercury is a bit strange and doesn’t act exactly as expected. This was such a problem, that we even invented another planet to account for its weird orbit. In fact it is this strangeness that provided evidence that Einstein was right all along. Let’s find out more. The orbit of Mercury doesn’t act like we expect it to, it has a rate of precession that is higher than expe...

Explain the rebound please. The core collapses at a quarter of light speed, leaving the gas/plasma surrounding the core behind due to inertia. The core cannot become more massive but the surface gravity would increase hugely and it would get hugely hotter but not enough to expand the core, as I pretend to understand the process. So what is the rebound? Rebound is when something shrinks then expands back to its original size, like a bouncing basketball. The core can't do that. So does the increased temperature of the core blast out an enormous amount of photons that push the left behind gas shell outward? So that would not be a rebound, but just an expansion of the gas/plasma that was not part of the core. Or is it something else?
Very wrong the plank temperature is a fake fictional value. As well as plank length do not "exist" cause there is no standard plank length the space contracts if there is a lot of nuclei in there so that is what we call gravity gravity make plank segments smaller and by that it contracts space so the waves pass faster through that. However we cannot represent that contraction of space with thermal units it is just not the same units. The space itself on small scale is not incredibly hot and there is no that much activity there. The waves are waves there is no photons. Space cannot be ripped space can be contracted and stretched the "stretching" happen on high scale as the gravity compact things like galaxies areas without matter do not compaction so they look stretched. There is no expansion of space it just means that our area our cluster makes our galaxy moves faster do to its spin around what we call the great attractor which should be some big "blackhole" black-star. there are no actual black holes black holes are black stars with particles that are more then 3 quark per basic particle they start from six quarks up to more. Also as the matter cools more its nuclei does have more energy as it does emits less energy. :)
Great video
There is this 5th force which is moving galaxies away from each other. This force is induced by free space. Free space has no matter but it has energy which produces this repulsive force. This is similar to free space ( weak or no field) b/w like charges which also generate repulsive force. Region of space which is occupied by matter or fields becomes a point of attraction due to presence of repulsive space around it.
Nice information sir can I use your video clip for education purpose?

The "Metric system" is SO much easier to learn while also being much more "Intuitive" compared to other systems. Here in Sweden 1dl=100ml 1 Liter=1000 ml, 1 Meter=100 cm, 1 dm(Deci-meter)= 10 cm, 1 cm= 10 mm, 1 meter= 1000 mm, 1 km= 1000 meters, 1 Mile= 10 kilometers and so on. I can't in my wildest fantasies understand why people would use other units of measurement when we have this simple system. Imagine how much TIME and energy that's wasted because of "strange units" 😄
How do expect to measure the speed of light when time and distance are not constant?

Hydrogen has never been converted into helium in the lab. This theory is a lie. It's an example of scientific bull shit.

Some annoying incoherent explanations pepper this otherwise apparantly acceptable account. For example, the 2nd release of neutrinos in a stars collapse "the star needs to get rid of all this energy". You mean the fitrst release of neutrino's wasn't good enough? And why does a star "need" to get rid of energy? Stars don't have purposes or goals. It's all the same to nature whether there is a star or a pile of bloody rubble. Check your text and get it sorted.
Instead of being paid by the hour, I wish I was paid by the planck time. Enjoyed the video!
This animation is so good
Our time space machine looks like a coffin.
General relativity changes the measures of time and distance so that gravity slows down the rate of causation.

Grey goo theory.
I think I've seen this once, welp, not complaining though
So what do you get when you take a Planck mass and compress it to the Planck density while raising it to the Planck temperature? Some units would cancel I think, but I'm too old for the math at this point so I am left with guessing. Maybe what you get is a Boltzman brain?
Would the magnetic field lines actually be visible from a relatively close distance, like in the graphic?
I think not
Maybe there's a shell of protons outside the neutrons because proteins are heavier? So the neutrons 'float' on top of the protons. Because gravity is indistinguishable from acceleration. So it's like a sea on the inside of the star
so much better without the background music. truly appreciate your craft and the way in which you describe the universe. welcome back!
Jokes on science I am already strange as hell and am immune 🎉🎉🎉
I really enjoy these videos, but I firmly believe that they'd be better without the background music.
I've just discovered your channel. I love the short and comprehensive format ☺️💕
I believe Einstein was wrong. Dewey Larson's Reciprocal System teaches that time is three dimensional and this is the real cause of the advance of the perihelion. The calculation is in my book, The Physics Rebellion.
Very interesting video. I learned a lot! Thanks
Great presentation.
Almost death itself, how are you scared of that, it is silly.
6:00 "However, it is believed they [relative observers] will always agree on the size of the planck length" This example is really misleading. You could have just as well said "they will always agree on the size of 1 meter". There's nothing special about planck length with lorentz contraction. The only reason your example is "technically correct" is because "the planck length" is a length, not an object.
many thanks for flavour vs colour info ❀ but especially for dyspraxic-friendly presentation for half spin ☆
