* All particles in the universe can interact with each other.

* We are systems of particles.

* Observation is interaction.

* We suppose we can

* Physics would be impossible if there were special observers.

f=(1-v^2/c^2) / ( 1-v^2*sin^2(θ)/c^2 )^1.5

where v is the velocity of the charge relative to the stationary test charge, θ the angle between v and the radius vector between the two and c the speed of light.

For v/c<<1, we can use a Taylor...

Relativistic Coulomb Force]]>

When two particles are moving at same velocity, the relative velocity between them is zero and it can be said that the particles are at rest relative to each other. If the motion of a particle is also compared with itself, the particle can be consider at rest with relative to itself.

We know that our universe is expanding. But if we compare the expansion of our universe, with relative to our universe...

A Chinese LEO (Low Earth Orbit) satellite named Micius after a 5th century Chinese scientist has achieved a new entanglement telecommunication distance record of about 1,500 miles.

A low bit rate channel for the entanglement test was established by means of an onboard beam splitter which targeted a pair of Earth stations separated by 1,500 miles.

Applications for the system include...

If you look diametrically opposite where you are standing on the outside rim of a relativistic merry-go round, you will see the greatest degree of Lorentz length contraction (distance contraction between the ponies or the stars), compared with the ones on the same side of the rim as you are.

First, satisfy yourselves that this is the case, and then tell us, what would be the effect of said contraction on your perception of...

Care to discuss?]]>

There is some discussion that information could be exchanged at rates faster than the speed of light. I've seen discussion that dissects the possibilities and shows that it can't be done.

However, how is the claim backed up that two entangled particles can remain entangled even though...

Testing Quantum Entanglement...]]>

To within 0.13 %, an experiment performed at the Large Hadron Collider in 2016 has confirmed that both the inertial and gravitational mass of the positron (antimatter equivalent of an electron) is the same as that of the electron.

The experiment boasts impressive accuracy, the residual 0.13% in gravitational mass differences in positrons vs. electrons attributed to differences in the proximity of Earth to the Sun during various repeat runs...

Antimatter - Antigravity LHC Results]]>

I understand (I think) that QM requires a certain randomness and is not just a lack of perfect knowledge as is the case in Classical Physics. Isn't it possible that with more knowledge in the future about how the quantum world works that the predictions of QM today could still be upheld but the underlying math changed in a more deterministic manner?

For instance Classical...

1. Consider two objects separately, an electron and the Earth. What are the eigen states of these two quantum particles or systems?

Correlating Newtonian Model with Einstein's GR]]>

The main purpose of this thread apart from general discussion is to discover what the terminology is used to describe the phenomena of a light source "appearing" at it's location when all we have is light info inside our eyes to deduce this from. (for the purposes of future research)]]>

Kirk goes into a " right angle torus " to get out of the tracter beam , holding the Enterprise .

My question is , how do we visualize this , right angle torus ?

What is the ship doing , physically ? In space .

I thought that Star Trek was liner , two dimensional . Because visually it never went up or down , three dimensionally .

But listening more closely the ship moved in three dimensional space ....
