Modern and Theoretical Physics

There is a concept which many physists choose to ignore. We all know that the Law of Conservation of Energy states that "Energy can neither be created or destroyed and that it could only be transformed". Now Modern physics has shown enough evidence that Matter on the other hand could be created and destroyed, however matter itself is 'frozen energy'. In a sense that energy is required to create matter and energy is released when matter is destroyed. Such that energy is always conserved. So if we look at the whole universe, and calculate the total energy of the whole universe by converting all the mass into energy and adding up all the elctromagagnetic waves and so on…

I was watching TV and came across a show on the science channel that claimed time travel was possible. This guy claimed that by using an array of lasers he could induce a frame dragging effect on the space/time around a device allowing him to send particles back in time. He also claimed that when the device was complete it should be possible to recieve messages from the future. Just wondering if there was any truth to this.

I read something about spin in electrons and I wanted to try an idea I have. Unfortunatly I don't know many of the formulas I need, so I'm asking for help. Here's the problem. I want to account for spin by having the electron actually spinning. I figure the fastest it can go is if it were orbiting a black hole. I want a small BH so I'm assuming its mass is the mass of the electron in question. I'll also assume the electron is moving with velocity = c, unless there's a more appropriet velocity someone knows of. For ease of calculation let's use a static BH, non-spinning, non-charged (I'd love to use a BH spinning and charged, but I doubt the formulas will even be legib…

Can anyone help me on my coursewrk I need to predict what will happen If the concentration of the reacting gas is increased or decreased, My concentrations are 20ml of 2 molar acid 20ml of 1 molar acid 20ml of 1.5 molar acid 20ml of 1.75 molar acid 20ml of 1.25 molar acid

i went back later to finish it for a particle that didn't move at c. i got a formula that says particles UNDER c have imaginary mass. i was under the impression that only tachyons had imaginary mass. what does this mean? [math]m=\frac{h(\sqrt{v^2-c^2})}{{\lambda}c^2}[/math]

Hi, I was just wondering if it is possible for an atom to die. eg If you had a hydrogen atom isolated somewhere on its own, say a vacuum box or something, would it stay in there with the same state forever or will it disappear? Also, with bigger attoms, will they break down to simpler atoms over time? Sorry if this is to basic but my knowledge of matter is limited Thanks

With all the time travel threads that have been popping up lately, I was thinking about this... Time moves at a constant rate, correct? if you were to travel through time at a greater rate, what would be the unit that describes that rate?

Hi I would like to know if there are proof of the mass increase at speed close c other than the one in the particule accelerator ? Thanks

Let's make the simple experiment. Clamp up an elastic wire ring in one point and pull it in radial direction. You will see three vibrating sections. Let's name each such section as quantron. Because the form of quantron has own mathematics. This process is named as a radial resonance of a not free (bond) ring. If you will hang this ring on four threads and put on the vibrate force of corresponding frequency you will see four quantrons. It is a radial resonance of a free ring. At higher frequency you will see six quantrons, then eight, etc., i.e. a mathematical row. At each moment of time the vibrating ring has the certain shape. The mathematical curve, which describes…

this is a pretty simple concept, look it up on google if u dont know it: basically my question was: if u built a metal suit, wore it, and got hit by thunder, would you be fine? assumin the metal can withstand the current. also are there any conditions, e.g. the metal suit has to be earthed? or does it have to be perfectl smooth, or can there be lumps, bumps, for your head, or where it joins together? and does a car work as faraday's cage if it is hit by ligthening, are the ppl inside fine, would they know about it? would they be electrocuted!?!

Could you tell me how to compute the electric field strength at the edge of a disk and the electric field strength of a ultra-long wire? Thanks!

Dear Folks: After seeing this Nano-tech forum... Nanalyze Forums - Direct conversion of heat to electricity http://www.nanalyze.com/forums/topic.asp?TOPIC_ID=1006੾ I sent a post to Rodney Cox president of Borealis http://www.powerchips.gi/ (I also asked him about Boeing's patent, and he did not reply to that. ) Could You please help me separate the wheat from the chaff? You should also read this speech given by Rodney Cox to IBM, it will give you a chuckle, shades of "too cheap to meter" http://www.borealis.gi/press/NEW-GOLDEN-AGE-IBM.Speech.6=04.pdf "Dear Mr. Cox, Were you aware of this patent application?

This: http://www.sciencenews.org/articles/20000205/fob4.asp article from sciencenews.org caught my eye the other day. It said that in Feb 2000 scienstists thought that they may be able to make artificial black holes. However, this was news from almost 5 years ago now - does anyone know if anything happened? (like if anyone actually ever made one?)

A while back I posted a thread on Teleportation: http://www.scienceforums.net/forums/showthread.php?t=2939 I discussed about how the transporter in Star Trek operates and why it would never work. Any procedure that convert matter to energy would be deadly and reconstruct person from this energy is a clone, not the original. In addition, the disassembly of crew members at the atomic level is not a viable option either due to the Heisenberg Uncertainty Principle. However, there may be a way to teleport a human: quantum tunneling. There is an article on the net about quantum physics and in one section, the author mentions about quantum teleportation. He…

If String Theory sucks does this increase interest in other kaluza-klein theories or put a damper on the whole thing?

unit problem of ILLUMINACE illuminance(E)= intensity (I) ------------------ radius®^2 also E= flux --------- area the first formula gives unit of E as cd/m^2 second gives lm/m^2 it seems that cd=lm but cd=lm/steradian mistake. where?

Two events occurs at the space point in a particular frame of reference and are simultaneous in that frame. Is it possible that they may be simultaneous in another frame?

Can anyone elaborate on what is known about it? Are there any implications for physics? I read somewhere that it could be an explanation for inertia. Could it be used as a source of energy?

okay, this is the most confusing thing i've ever seen, i've taken it to my physics teacher and he suggested something to do with antiferromagnetism, but if it were that it still lacks in explanation for parts of it... so here goes. if you really dont trust me then i can try and prove it to you, but the videos would be hard to do and even they could be fake so please trust me, what i say is weird but i swear on my life it's true, if im not specific enough, say so. okay, so we start off, im obtaining a NIB (neodyium iron boron) magnet from inside an HDD, it took about 1 hour to do due to the screws blunt-ending and further problems, but in the end i got out the NIB!…

Earlier in this category, I began a thread on Grand unification. I asked what kinds of things must the final supertheory of physics explain, and I got some nice answers. Some things there, I doubt I will ever understand. I am posting this thread here, because it seems the natural place for it. I've been reading a lot of things going on in physics today. There are so many physicists coming from so many different angles at "who knows what." They cannot all have the right approach. I've seen things on M-theory, which I have no clue about. I've seen things on string theory, which I also have no clue about. I've seen physicists poking fun at each other, for not …

Suppose that anything which historically was referred to as a particle, is really just a node in a traveling wave. So this would hold for 'photons'. Electrodynamics leads to the conclusion that what is vibrating, in the case of our "photon nodes" is electric/magnetic fields. Photon's propagate in vacuum. My question is coming up shortly. I am thinking of a piece of thread which stretches from the earth to the moon. The thread is taught. It's vibrating, there are nodes in it, the nodes are moving in this frame close to the speed of light. Here is my question: What is the string? I don't see any string. There is no string. The notion of a un…

I learned from my physics class that it is the strong gravity of earth that not only binds us to it but also keeps the moon in orbit... in a similar fashion that the sun by its extremely strong gravity keeps all the rest of the planets (that we know of) in orbit. Ofcourse, centripetal forces are also involved here but what I wanted to know is the energy source for this gravity.. more specifically, the source of energy of earth's gravity. Is it located at the central core of the earth, as some would predict?? what does it look like?? at what rate is the energy being used up (the power, i.e) and, if it goes at this rate, at approx. what point in time will it be totally …
