hey Kurzgesagt, in this video you explain particles but what about waves? are all (quantum) waves made of the elementary particles or are they something different?

@kurzgesagt since when gravity is a force? There are no (known) force carriers for gravity. Gravity since Einstein looks as if it is an emergent property of spacetime and not a force. Am i wrong here?
Artur Renato B.B (7 дней назад)
The curvature of spacetime is gravity, and that is regarded as a force.

So dark matter and dark energy are not things. Makes sense, we invented them because physics only explained about 5% of what we saw in the universe and then continually failed to find them.

People, no need to bicker, I will define Nothing for you. Nothing is the true and only distinguishable. Nothing is the opposite, or inverse of something. It stands to reason that everything that can ever satisfy the equations and definitions of something must not be able to satisfy nothing. In other words, everything and anything that something is, nothing perfectly is not. Does something/anything/everything exist? If yes, then nothing does not and can not. Something can be understood, nothing can not, something can be measurable, nothing can not, something can be observed, nothing can not, something can be created, nothing can not, something can be destroyed, nothing can not, something can be comprehended, nothing can not ........

Plads Elsker (29 дней назад)
wait, but gravity is just an illusion according to einstein... so is the fundamental force of gravity not a thing? and if so, why would the other fundamental forces be things? what if it's all the same force that just seem different from our perspective..?
Plads Elsker (7 дней назад)
Well, man, thanks a lot. I defenitely learned something here :) I'm gonna see if i can get my head around these tensor fields. Have a good day
Artur Renato B.B (7 дней назад)
Yes, the vector and scalar fields are just subsets of the tensor family. As to a proper explanation, I really can't go much further. I'd recommend checking : "Physics videos by Eugene" , he has a fantastic intro to GR and what tensors are. "DrPhysicsA" , just overall great Also, no I'm not in college yet
Plads Elsker (7 дней назад)
yeah, thanks so much! I suppose you followed a course on advanced physics at university? Classical mechanics and einstein's GR are so intriging to me, it's really nice to have a bit of a course on the subject. I'm not sure if i understand well your tensors explanation, thought. Precisely when you said the following: "Imagine a bunch of. vectors. They can represent surfaces, or oone object can have multiple of them. Multiplying them a togethers gives us a tensor, they can come in different ranks, matrix numbers and all of that, but they are all fundamentally the same." Do you mean that the vector-field set and the scalar-field set are both sub-sets of the tensor-field set? And if so, then is einstein's GR a scalar field?
Artur Renato B.B (7 дней назад)
Well, scalars are mathematical entities. Imagine each point in space containing a value, called a "magnitude". Using this tool we can describe many things. For example, air density is a scalar, as each location has a magnitude of density attributed to it. Sound is just a propagation of oscillating densities in this scalar. Temperature, humidity, or the quantum Higgs field are all scalars. - Up from there we got vectors, scalar fields were each point in space has also a direction coupled with its magnitude, so a arrow. The electromagnetic field, fluids (such as liquids, gases, our atmosphere, sun), and the weak nucler force are all vectors. - All of these, scalars and vectors, are part of the family of the tensors. Remember our jump from scalar to vector? Same thing here. Imagine a bunch of. vectors. They can represent surfaces, or oone object can have multiple of them. Multiplying them a togethers gives us a tensor, they can come in different ranks, matrix numbers and all of that, but they are all fundamentally the same. Why am I telling you this? Well, when Einstein had his ideas on GR, he used the at the time newly developed tool of tensor calculus to express them for a multitude of reasons. Thy become clear when you see what gravity is and what a force is: Firstly, you saw the mechanical definition of force, that is, the one we use in classicsl physics, but forces are more than that : anything that causes a reaction or has influence over a physical system is a force. The strong nuclear force acts upon all atomic nuclei, electromagnetic force controls all charged particle interactions and photon behavior. Gravity, well, gravity is the complication; originally, Einstein described spacetime in the matter of Minkowski spacetime, the same used in Special Relativity. This description perfectly fits all the pieces, like time dilation, lenght contraction, and speed of light constancy. Gravity wasn't a factor then. Until mr.Albert realized some stuff that you can look into later, and had the insight that spacetime is flexible. Bendable like a rubber sheet, a 4D one. Much study later, he finished his idead that mass and energy create a stress, described by the Stress-Energy 4D tensor, onto spacetime. That curvature was explained through the Curvature Scalar, and the Ricci and metric tensor. These deformations created a force that acted upon bodies because of the pure stress of spacetime itself, so gravity, the thing you're feeling right now, is the force of spacetime generated by this curvature, thus gravity is the curvature and thus is a force. You could say spacetime is gravity's quantum field, but that wouldn't be so accurate. Anyways, I hoped this got you a better idea of the issue
Plads Elsker (7 дней назад)
By "scalar field", do you mean something progressive, a bit like a 2D or a 4D function? So the real debate here is not whether gravity is a force or not, but whether it's a Graviton-driven or 2D/4D function force? According to wikipedia: "In physics, a force is any interaction that, when unopposed, will change the motion of an object." So i can't come with any reason why gravity would not be a force. Thanks for your reply.

Empty Space IS something. Therefore NOTHING does not exist and that's why we have a God. The beginning of all. When creating the universe the first thing God said was "Let there be Light" and that's where everything comes from.

If nothing is something, and something can be nothing, what is?
James Lysander (1 месяц назад)
Yo what the fuck that sounds similar to the Christian/Hebrew creation story in detail, it is said that before anything was created, he existed, fluttering over "the deep waters", which refers to some sort of infinite ocean made of nothingness, it goes on to say that "darkness was on the face of the deep", showing that this infinite ocean was dark. It is said that he spoke, and caused light to be and that from that light all things were made. That light could be the energy on this ocean, with there being some higher consciousness exciting the surface of the ocean to create reality. This could also explain why -what- consciousness is, is so important to us humans?
Artur Renato B.B (7 дней назад)
That's just because of original philosophical ideas that they had at the time. One good variation is the greeks concept of the universe being made of water, the logic follows like this : The universe is composed of forms. These are the superficial, moldable shapes, and the essence The universe then, needs to be made of a dynamic, fluid substance, that is just the essence Thus, water is the main constituent of the universe ---
