Einstein's General Relativity Shows that a High Voltage Electric Field Changes Spacetime Curvature to Warp Space, that a UFO Can Use for Transport

Here is a theory, showing that a very high voltage electric field can be used by a UFO for transport. The theory is based on Einstein's General Relativity, and how electrons and protons behave in an electric field. It explains how UFOs can maneuver in ways that seem to defy the laws of Newtonian physics. Here is the derivation of the theory:

Einstein's General Relativity (GR) field equation is a relatively simple equation. But its actually very complex, because each variable in the equation is a tensor variable. So the mathematics that this simple equation represents is extremely complex.

But the GR field equation, itself, is very simple and easy to understand. It shows that the variable T on the right side of the equation - represents Pressure (among other things):

T mu nu on the right side of the equation represents the following matrix:

The terms in green, T11, T22, T33 in this matrix are Pressure:

https://i.imgur.com/u1jX3J0.jpg

The left side of the equation shows to what extent Pressure will distort space (change spacetime curvature):

https://i.imgur.com/bNFOfaY.jpghttps://i.imgur.com/bNFOfaY.jpg

Pressure can be positive (like pressure in an inflated tire). And Pressure can also be negative (like in a stretched rubber band; or in an exercise resistance band that a man stretches to build muscles). The elastic force drawing the stretched band toward its unstretched position is negative Pressure, Tension.

So,the GR field equation shows

Distortion of Space (on the left side of the equation)

is proportional to

Tension (on the right side of the equation)

Physicists previously determined that UFOs could maneuver in their seemingly impossible ways if they could distort space for transport (i.e., if they could squeeze a very large amount of space into a very small amount of space).

So if I move some charge to somewhere else, let's say very fast, will the field around it drag somewhat behind? Or will it move with the charge regardless of the speed of motion (which would make it seem instantaneous), not being affected by the speed at all?

I wanna say sorry for not getting a chapter done for you people, not to mention this special having supposed to be a bonus to go along with 140, but holy shit what a week.

I will not be able to give any guaranties as to when the next chapter is coming out nor is the Christmas special I was toying with going to happen. I simply haven't got the minutes to spare these days since everything for our uni project just kinda went tits up at the last minute and now it's time to start prepping for exams in january... of which the first on Jan 3... yay...

With the whining out of the way, I do hope you enjoy part 4 of the special even if it's both late, and not the main story. I am sorry, but hopefully it's at least funny.

Electric field in an atom.

How do charges in a neutral atom cancel out?

The answer that an atom has an equal number of protons and electrons doesn't satisfy. The simple model of an atom is that protons and neutrons are next to each other and, a bit further, electrons are around them. So, in my opinion, the only place where charges* cancel out is a circle between protons and electrons. Outside an atom, the negative charge* should be much stronger than the positive charge*.

Crucial edit here:

By writing charge (in places with *) I was thinking about fields. Nevertheless, the question is valid because if the charges were cancel out, there would be no electric fields.

Hi, my classmate and I can't agree on what the r in calculating the electric field in the distance between a negatively charged rod and the particular point of calculation. Let's say the point of what we are calculating the electric field is at (-a,0). Would r be (a +x) or (-a + x) when integrating? I believe that it would be (a+x) since x-(-a) = x+a. It's a little harder to conceptualize with the point being before the rod. I appreciate any explanation.

This doesn't seem right. Why does a spherically symmetric charge distribution not lead to an outwards pointing field? I feel like I must be missing something.

If I was measuring the amount of current flowing through this circuit with a very fast multimeter, would I see the current decrease as the leading edge travels across the circuit, as shown in the graph above? Also, when if I was to move the return path(bottom wire) further from the top wire, but kept the total length of the wire the same, would I see energy loss because the fields have to travel more?

They had partially closed the larger entrance behind him, a kind of rolling door coming down from above. It was much warmer inside than it had any right to be given the lack of large fires.. He wondered if that had something to do with the amount of people running around. They were supposedly all warm after all, and well, he had felt Tomβs body heat a few times before. βyeah that must be it.β

The noise and smells though, They were the real party piece of this place. So many people were all talking vividly, and mostly about them. That wasnβt too surprising, he had started getting used to it by now. But the sheer amount of people who questioned if he could breathe fire was just getting annoying. It wasnβt like fire was any better than lightning. He had promised not to do a demonstration though. It didnβt seem like a good idea anyway with this many people around.

Then since E = E1 + Ehole, I solved for Ehole but the answer below is wrong its supposed to be ( pb)/(3e_0) , can someone explain what the steps are? thank you!!!
