Modern and Theoretical Physics

first think what happens if something deaccelerate and accelerates same time! then other way accelerates and deaccelerates same time think first that before adding to it anything physical just theory

What if the universe was arranged as a spectrum? What I mean is, what if locations, which recent findings show may have variations in the laws of physics, could be arranged on a spectrum (or a curve) by their variation of the laws of physics. Like, let's say this: Now, let's say that there are three locations in space: Location 1, 2 and 3. They are millions of light years away and have variations in the speed of light. Now, let's arrange them on a spectrum: <<< Slower |----3------------------1-------------------2-------| Faster >>> (no, it's not perfect and I didn't want to plot them on another image) And on a curve: …

Due to the nature of the em field, particles and their antiparticles are attracted towards a collision point of 90 degrees? Two spheres,(not points), spinning either with or against their forward momentum headed toward a 90 degree collision point , (photon), will collide just before their centers would. This collision mediates their angular momentum, rotating around the new center of mass like a propeller. This geometric race track for force must have some fundamental role in force relationship? Any related analysis is appreciated.

I have been reading a book on QED by Richard Feynman (The Strange Theory of Light and Matter). In it he describes what appears to be a real dual slit experiment using a low intensity source into a single photon detector. I have found avalanche detectors and photomultipliers and that is all well and good. Where I have a problem is when he puts a detector near each slit to see if the photon went that way, saying that the interference effect goes away when you "look" like this. My problem is that he seems to be describing a real experiment but I can't understand how a detector can detect a photon as it passes by. The single photon detectors I have seen "consume" the phot…

Alright, we'll I'm supposed to be writing an article for my high-school newsletter. Being a lowly novice of physics, I thought I'd right one on the Alcubierre warp drive. Any tips on how to really dumb the physics down? Should I really mention positronium, or any other exotic matter? What about a Miguel Inferormeter and how it curves space-time by its appearance in energized states?

I decided to observe planets orbiting around the sun through a telescope. I calculated the motion for instance of jupiter using mathematics. I though of trying to compare the results with the ones of another observation, that one being when I observe how electrons were behaving when projected on a wall, passing slightly before through two slits on a flat surface in front of the projector. The reason why I decided to compare both observation is because they both contain a common point, wich is the speed of light. The results of both observation were that when I observe the motion of A being both planets and electrons, I always come to a different result than when I don't m…

We theorize that the Higgs boson makes things massive. I wonder if there is a similar particle that makes things living? We hear terms like "life force". and "Life energy", but are there any theories as to a life force particle that interacts with with life possible chemistery? We can see plainly that living things eat other living things to extract the energy they need to survive as a living thing. If we could discover such a particle we may be able to better pinpoint planets worthy of further investigation in the near star traveling future. Perhaps scan mars and titan for such particles. I don't know, what do you think?

So me and my classmates where debating if it is ever possible to contain a Nuclear Blast and eventually stop it's nuclear chain reaction using only pure energy and plasma. Any other theories?

If a meson is an antiquark what is a virtual quark/meson? I thought a virtual particle was another name for antimatter altogether is this the case? If you could provide a resource it would be appreciated.

This came up in another forum, and as of yet we weren't able to come up with an answer. Someone posted the following pdf about KK theory: http://www.weylmann.com/kaluza.pdf . In it, the Lorentz force law is derived from the 5D geodesic equation. What was puzzling us was the appearance of an additional term: [math]\frac{d^2x^\lambda }{ds^2}+\Gamma^\lambda_{\mu \nu }\frac{dx^\mu}{ds} \frac{dx^\nu}{ds}=-kF^\lambda_{~\mu}\frac{dx^\mu}{ds} \frac{dx^4}{ds}-\frac{1}{2}kA_\nu F^\lambda_{~\mu} \frac{dx^\mu}{ds} \frac{dx^\nu}{ds}[/math] This is troubling for two reasons: (1) there's no experimental evidence to suggest deviations from the traditional Lorentz force law, and (…

I have been thinking recently about this, but I haven't really found a clear answer to this online. Almost all examples consider only two things, a stationary observer+Moving object. Now I wanted to know what exactly would happen if there was more than one observer, each one affecting spacetime differently (Through Gravity or Velocity), and each one can observe one another. As an example, let's remove velocity TIme Dilation and only use Gravitational Time dilation for now. Also, let's specify who exactly are the observers and where they are exactly. The first one is Tim. Tim is orbiting around a Supermassive black. His clock will be ticking the slowest The second …

Can someone help me put together what particles there are in the universe...I know this sounds outrages because there are so many but what umbrella terms should I know in order to categorize them all. For example what is a meson, boson, fermion, and lepton...are these all related under one term etc. could you please advise me on helpful resources as well thank you.

I was reading on the creation of matter shorty after the Big Bang, and about the fact that more matter was created than antimatter. Then there was this explanation that kaons and antikaons don't decay into the same particles, and how this could explain the asymmetry between matter and antimatter. Is there any modern explanation why this kaon asymmetry occurs? I'm a layman so I'd prefer a non-technical explanation.

I've heard many physicists put forward the second law of thermodynamics as an explanation of the vector of time. Can someone explain to me why that is not circular reasoning? It seems that it merely says that entropy increases with time therefore time must increase with entropy. How is that not circular? Isn't a better proposal needed for an explanation?

Can there be imaginary mass resulting from negative mass instances? And how would it alter the point origin of the universe? Would it bring time before origin into life?

Let's see...very sleepy We have gravity,light,matter,life,energy and stuff. now Facts: The moon is orbiting the earth, earth orbiting the sun, sun orbiting teh galaxy, and the galaxy is moving really rerally fast... and we don't feel it because we are affected by the gravity of earth,moon, etc...in einsteinas' theory crap...GeneralRelativity in spoace something makes gravity andstuff...gravity is energythingy now...is it possible to creat artificial gravity inside avessel that will cancel out all the othereffects of other forces of gravity exerted by matter outside the vessel? so that if everpeople go inside it they would not be affected by inertia when they wou…

According to Wikipedia: http://en.wikipedia.org/wiki/Space-time_crystal Nobel prize laureate Frank Wiczek published in effect something like my idea that I've put in the speculation thread. Maybe my idea isn't that speculative after all. At least I've come up with a simple way to test it.

Doesn't The Fact That The Universe Is Expanding (the Space Between Galaxies Are Moving Away Not The Galaxies Themselves) Prove That Matter Doesn't Actually Move And It's Just The Space That's Moving?

Imagine a spaceship traveling at 99% speed of light. Inside the capsule there is a gun. when it fires, space time will be warped so that the time around the bullet is reduced to such an extent that it doesn't break the speed limit. But what if instead of a gun, a flashlight was lit? Would it emit light like usual?

Hey, I'm in a sciene club at my highschool (lame, I know ), and now we're coming up with a new project to do. My teacher said "No project it too big", so I want to make a atom smasher, like Michio Kaku did when he was in highschool (mostly to take pictures of tracks of anti-matter) Unfortunantly, I can't really find any good sources to do this on the interwebs to do this... Any ideas/ tips/ resources?

I have a very elementary understanding of physics, but from what I understand there are several physical constants such as the Newtonian constant of gravitation, the Planck constant, and the speed of light in a vacuum. I've also done some reading on quantum physics and string theory and I remember reading an article about the possibility of the universe we live in being a complex simulation of sorts. As I got to thinking, I couldnt not understand why physical constants like the speed of light exist. Why is there a maximum velocity; An exact number where acceleration stops? It seems like something that is hard-coded into nature. I cant seem to fathom why ther…

Is it agreed among physicists that the proton is not really made up of just 2 up quarks and 1 down quark? It is really made up of an unknown but extremely large number of up, down, charmed and strange quarks, plus gluons and that on average there are two extra up quarks and a down quark? Does this account for all the particle that are produces when they are collided at the LHC.

Hey thre, do you guys know how do I visualize trajectory with Maestro??? First I added solvatation box of water with Desmond, than I did minimization with macro model and molecular dynamic with macro model, now i cant find the way to view trajectory, can anyone help? thank you

whats the difference between a tensor and a vector? are they even related?

I can't get to grips with what came first - why was there a big bang and what caused it. If all matter was compressed into a very small area in the "begining" where did it come from, where did the first ever gas or matter come from? There must be some intelligence in the design of the universe. Look at our world, all living things have been designed through evolution to live successfully in whatever environment they live in. Therefore, I have a theory that absolutely nothing in the universe exists, and the energy that is produced from being a state of "nothing" creates an intelligence or soul that has the ability to create an illusion of a living universe and fantasise wh…
