Gravitation abot collision time
What does “abot” mean? If it’s a typo for “about” the title still doesn’t make sense to me.

I want to know where matter comes from
Quarks are not “made up of energy”. They have energy, but they also have other properties, like spin and electrical charge and color charge, which are just as important. If they were just energy they wouldn’t be quarks.

Range of Angles of Applied Force on an Inclined Plane
at some arbitrary angle The quantity you care about is the one quantity you didn’t assign a symbol to.
comment
Why would the normalisation of a vector with 2 complex numbers only give us 3 real parameters?
The fourth isn’t independent because it’s determined by the normalization.

Solutions to the Geodesic deviation equation
Geodesic deviation on a unit sphere It’s probably solvable in any maximally symmetric space since in those the Riemann tensor can be expressed as products of the metric tensor.
comment
Would you consider my theoretical questions?
By shooting a laser at something, you are creating the direction that the light came from. Not in mainstream physics, which is the only kind of physics on-topic here.

What is the self-potential of a point charge?
You may find the related concept of self-force interesting. It’s a fascinating topic and its effects can be observed.

Meaning Propagation of Energy and Energy per unit volume
@flippiefanus I’ll just delete it. You answer if you want to. I don’t want the points.
comment
What is the self-potential of a point charge?
Yes, it’s infinite. When you get to quantum field theory you’ll learn how physicists sweep infinities like this under the rug using a process called “renormalization”.

Radial coordinate transformation in General Relativity
I think eqn. (30) in the paper is true only to first order in $G\mu$.

The energy required to pull a quark out of a nucleon to create a pion
In QFT you can do perturbation where energy and momentum are conserved at every interaction vertex, so there is no need to worry about where the energy of a virtual particle “comes from”. But the off-shellness means that the virtual particles don’t have the mass that they “ought” to have.

Can we combine Lattice methods and $\chi$PT to study complex hadronic phenomena?
Does $\chi$PT mean chiral perturbation theory?

The energy required to pull a quark out of a nucleon to create a pion
The pion in the video is a virtual pion. Virtual particles aren’t on-shell and thus aren’t real particles.

Could a Kinetic Matter-Antimatter Singularity Collision Model account for Baryon Asymmetry and the Axis of Evil?
@James all known things rotate That’s not true. You just like to make stuff up.

In the last 50 years you are the only person I’ve met who is interested in this fluid picture. I don’t know where you live, but it wasn’t part of my physics education, so I have a hard time believing that it has much to offer. If it was useful, it would be widely taught, and it simply isn’t.

I was responding to your comment that the Schrodinger/Madelung fluid is the universal vacuum.

@James You seem to be fixated on an irrelevant historical curiosity. The Schrodinger equation can’t explain high-energy physics because it’s non-relativistic. It has nothing to do with decay rates because it can’t describe particles being created or destroyed.
comment
How does Schrodinger's cat experiment relate to black holes?
particles that make up a black hole A black hole is not made up of particles. It’s a vacuum solution of the Einstein field equations. (Or, for a charged hole, one where the stress-energy is due to an electromagnetic field but not to charged particles.) Also, in General Relativity black holes are classical objects, not quantum mechanical ones. So it’s really unclear what you’re talking about.
