Matter is anything that takes up space.

You have the standard model. This is my current understanding.

It's actually a very interesting question as to why we even have matter in the first place, considering it should annihilate with antimatter.
>where did it all come from
matter is just a form of energy, so all of the matter we have now resulted from the energy of the early universe. I recommend the wikipedia page on "early history of the universe" for this

>>11917497
Ok but that just transfers the question to what is energy.

>>11917503
Which is a difficult question, at least to answer in a fulfilling way.
My answer to "what is energy" whenever younger students ask is "the intrinsic capacity to do something, cause a change, or affect something else."
We know that there is a lot of total energy in the universe. We don't know why there's energy at all. It's true that energy can come out of nowhere and disappear to nothing, but these fluctuations are most often undetectable because they're so small.
Unfortunately we have no idea why the big bang happened in the first place and why there's anything instead of nothing. This is beyond the scope of physics, at least at the moment.

Almost like they're poking through the curtain..
Tell us more

Matter is encapsulated energy...somehow.
High energy gamma photons get "enclosed" when they hit each other.
Why is there that threshold that prevents IR photons do the same?
How is the process in which 2 gamma photons end turning into a positive particle/pole and a negative one?
The enclosed EM fields end being opened, while the space/time propagating photon ends being self enclosed, why?
Why?

there is an uncertainty relationship between energy and time, similar to the heisenberg uncertainty principle between position and momentum. you can "borrow" energy from nothing, but this energy can only exist for a short amount of time, and the time is proportional to the amount of energy you're borrowing.
>poking through the curtain
god I wish, that would make physics more interesting. however that is again beyond the scope of the field and delves into metaphysics.

>matter is encapsulated energy
matter IS energy, as seen in the meme-y einstein equation. there's no "enclosing" happening, it's just the transferring of energy from one form to another. similar to how you can have chemical energy, potential energy, kinetic energy, you have energy in the form of matter.
high energy photons can turn into matter because the rest energy (the energy required to form/the energy released when it breaks) of an electron requires photons of enough energy. bound massive particles have a mass, and in order to create them you need photons of enough energy to correspond to this mass. if there was a hypothetical "superlight electron" then IR photons could "bind" together, although this isn't the right way of thinking about it.

not sure I understand your last two lines.

none of this shit is even real lmao

Fascinating...

God

>>11917545
And if everything is energy, on what does it cause a change? Other energy? Thus is everything kind of like a big field of energy and its interactions?

And what even is a field, and what is space, where this all happens? So many questions with seemingly no answers

>>11917469
It all came from The big bombie

Or all the protons and electrons at least
There's probably a way for neutrons to fuse from protons + energy

Does the number of neutrons decide chemical composition? Everything would decay back to hydrogen without them

Do you think there are solar systems formed from mostly H-1 and H-3 fusion, if we are H-2?

Wtf is "spin" is my question

>>11919771
A degree of freedom that correlates to the conservation of angular momentum.

>>11917469
lmao chill out bro its just a prank

>>11917469
I still just cant rationalize how solar sails work. How does light push anything? How can you have momentum without mass? What is happening in the conversion of light energy to mechanical energy?
Is it heat radiation doing the pushing?

>>11917469
>>11917503
"hard" light

>>11917565
pressure mediation

>Matter is anything that takes up space
And "space" is everything else but "space", defined by everything else but what it might be. So what does that make it?

holy shit this is the same thing with brushes, entities and level in a fps map editor

Hello, I am here to enlighten you.

These "science" guys will oppose me because their egos are inflated and built upon knowledge of giants, but giants lie and decieve them. They know not what they teach.

Here is your answer in a form that is allowed to the public.
