if magnetism is just relvestic effect of electric field due to length contraction then what is light as what ever I have learned is that its a magnetic field which produces a electric field which in turn produces a magnetic field but since they are the same things and can't produce each other and only depend on point of reference then what is light? So that any one who believes that he knows what light is gets confused/

Light is both a wave and a particle? That's not too surprising to me XD I have this theory (It's probably already been theorised many times before) that a photon is a wave, is invisible but always exists. When it comes into contact with energy (eg a particle), then it picks up the energy (like mobile phones use carrier waves to send unique data depending on the phone number, AKA the frequency of the wave). When you see light fading, all you're seeing is the energy dispersing from the photon but the photon still exists. Think about it, a massless particle always will travel at the speed of light (aka the speed of a massless particle) and has no mass which means it passes through other matter. The reason why mirrors reflect light is because the energy that's manipulating the wave itself changes direction, and pulls the photon with it. At least, that's my theory

I like your thoughts above. Your "photon" sounds suspiciously like the electromagnetic field. It is everywhere and information travels at the speed of light. Light is an electromagnetic wave. Imagine the em field as an ocean and light as some kind of ocean wave. (That is not how it is like, but if it helps... (sorry had to put that quote there. Who recongizes it? (did you notice I like brackets?))) Photons, on the other hand, are like energy-units of light. You can have different-sized energy units, but two photons with n energy are not the same as one with 2n energy. If you think of light as particles, that makes sense, but with waves... (btw that is what the photoelectric effect is all about) Ok, enough confusion for toda... um.. tonight. It is very hard to bring the two light models together. (is models the right word?)

You do realize not all particles interact the same way with other particles right? For instance, radioactivity is particles, but you're going to have a hell of a time collecting them, since they pass through most other particles (in fact, that's how they cause mutations in large quantities). Trying to be snide and insinuate that particle duality isn't real just because you can't catch a photon in a glass (btw, they HAVE caught photons in specially prepared crystals recently) is just ignorance on your part.

The one electron universe theory says is that the electron travels forward and backward through time creating multiple instants of itself considered by us electrons when it goes to the future and positron when it goes towards the past creating like this the space-time. When electron/positron interact(all the time) they create a spiral shaped motion (photon) like a twisted two way band. So a spiral (wave) is a path through space-time. Light is also a wave or a spiral therefore a path through space-time.

What happens when you put a detector by the slits? I read somewhere that if you do that, the interference pattern disperses and you get the particle effect. Not sure if this is correct or not, or the person who did it performed the experiment incorrectly.

Ok.. check this thought out.. What if Light is a particle, but it's is moving in a very tight Vortex. Like a compact "photon train" but the train tracks are vortex. Which from certain perspectives will look like a wave. ie: in two dimension a vortex looks like a wave from the side, but straight on it would look singular like particles. A vortex would act as both in observations. what do you think?

I have a thought experiment. Take two particles and quantum lock them. That's when you change the spin of one, it mysteriously changes the other's spin to match, thus locked. Then take one and throw it in a black hole. Since they are locked, you can measure the one you have, which is like measuring the one you threw in. So what will we see when we throw it in? What would happen if we tried to change the spin? Could we even change the spin?

@villemattias

hughstout The fact that light gets "dimmer" further away is because it spreads out so much and/or gets absorbed by particles in the way. Yes, the sun has a strong gravitational force compared to earth, but it's nowhere near powerful enough to bend light dramatically visibly, but it does happen just a tiny bit. Compared to other objects the sun is very "lightweight". Insanely dense objects like neutron stars or black holes have so much mass, and are so "small", that they have a strong enough gravitational force to bend or trap light.

Of course light is subject to gravity, because gravity is the effect of mass on the surrounding space, and light travels through this bent space. This was first proved in 1919 and made Einstein famous overnight for predicting this.

Anyone recalls the formula: mv=h/lambda. Probably this formula explains somehow. I forgot. Maybe it's like if the mass is too much, then it's wave length is too short, so it's a particle or if vice versa, it's a wave. But probably in case of light, both the properties are in the middle. So, it can act as both particle and wave. (Perhaps, can't remember with certainty)

I've been thinking. Waves don't have any particular direction. They are always moving in all directions. So how is this different from a single particle moving in random directions? Even if it's moving in random directions if it's doing it at the speed of light then it will still behave in a somewhat predictable manner. It will always have more likely location at a particular time.

The mathematical possibility of different crystalline structures for solids .-. That's an interesting one to think about. Like, in an extreme example, the ice-9 from Cat's Cradle; a fictional form of water that would form solids at much higher temperatures than normal ice (potentially freezing over most of the world's water if a seed crystal either was formed in nature or placed artificially by science. The seed crystal would expand, causing the rest of the water to form the same atomic structure due to the positive and negative attractions of the original seed, and eventually freeze all water connected to the original source.) Are there actual cases of multiple solid forms of a single element or compound? If so, what elements have this property o.o?

It gets weirder. They did the double slit experiment with a light source so dim that it only emits 1 photon at a time, and recorded where each photon hit the detector. The photons still followed the interference pattern even though there was no other photon present to interfere with. Each photon was going through both slits and interfering with itself.

If light is a wave then it needs some medium to propagate in vacuum ... Is it right so .... What is that medium .... And why we can't see it or feel it ... Like air We know sound is a wave it propagate in air we can feel it some times see it... But in vaccum we can't hear sound.. It means sound and light wave has different medium to propagate So ... Plz plz plz tell me which medium light wave travels in vaccum

Mechanical waves need medium to travel (like waves on water, sound waves). light is electromagnetic wave, electromagnetic waves don't need any medium to pass they can pass through vacuum. Also we can feel light (our eyes).

Light is a field pulse perturbation that's rate of induction is dependent on the medium in which it propagates. That is why light inaccurately appears to speed back up after passing through things like glass. It's not moving. It's not passing through anything. You're witnessing compressions and rarefactions of the pulse perturbation.

This is not just a property of light but all subatomic particles at the "quantum" level. That is all particles operating as homogenous groups of the same particles such as plasmas, ions, charged particles or any group of particle separated from there common surrounding via thermionic emission or arc discharge display particle/wave duality. What is interesting is that if the universe is composed of a "dark fluid" then one would expect to see such effects in cold states of matter at the Planck level.

So here is a interesting question, can light still be light without the waves or particles, that light seems to be made of? If not, then is it possible that light has similar characteristics to elements that are on the periodic table, at least in some way?

Obviously not. Light is not made up of atoms, protons, neutrons, nor electrons. It's made up of photons.

Why do we prefer warm food over cold food? Is it because in the past we wanted fresh meat (Warm) over meat that was killed yesterday (cold) ? Or could it be that we developed this later on, as cooked food would be sterilized, and cold food could have parasites? I'd like to hear about this, as no one seems to talk about it.

Question from the TV show "The Big Bang Theory" Why does carban atoms traveling through the a graffine sheet act like they have no mass? it was said to behave like a wave at the end instead of particles. why is this?
@iNemerAli
@iNemerAli 10 жыл бұрын
Here is a question, please. What will happen if you: Start the experiment without the detectors on the side. The light start to behave like a wave. Then you add the detectors while the light is behaving like a wave to the experiment, to see where each photon goes. Would the light still change its behaving?

Light is Basically travels as a wave made of up of particles. So I differ from the traditional explaining of light as either Wave or Particle and can't be both a the same time. I Affirm that light is made up of tiny particles and travels across in the form of wave! This can be easily explained by the experiment of water flow or gas flow. The water when flows from a tiny hole it spreads in all directions but are made up of water tiny molecules H2O which are essentially particles. Similarly gas flows through a narrow opening and spreads in all directions ( either in air or in vacuum). even gas is made up of tiny particles . It is the same case with the air , when it flows through a narrow opening into the vacuum or to an region where the density of air is less. It spreads in all directions . but basically they too are made of tiny atoms or molecules of elements. The light has the characteristics of emitting or pushing the tiny photons or packs of energy in the form of waves in which the photons are again made of waves of energy having no mass, no form, no color but only warm presence. These photons particles are so tiny that they can pas through skin or flesh of animals, plants because of the pores or gaps in between the cells and can even pass through water or gas. So we can have Xrays or Radio waves that can travel across. They can even pass through vacuum and do not require a medium since the photons are pushed by its source and its reach depends upon force exerted by the source for pushing them across. In fact the reach of light made of photons can even be explained how far a man can extend his hand to touch anything. similarly a source of light can reach its light as far it can extend its light ray much like a man can extend his hand. So the light ray is the integral part of the source emitting it. We can actually reach the source of light through the ray of light or even can can make changes in ot or affect it someway if we are able to do that or able to withstand the heat of it ! We can reach the the planets, Sun and stars if we are able withstand their heat or affect them the way we want by travelling through the way of photons it emits. This is largely possible by light itself , that is by counter emitting photons from a source in which case the photons will travel through the path which the source of emitting photons already created through its waves to reach us. Another Fact is that the gravity of Earth and other planets is formed by emission of light by the Sun in our solar system. The photons emitted by the Sun reach the earth and heats of the land, sea and the air surrounding it , this heat gives a spin to the planet Earth and rotates in its axis since the other half of the Earth is not exposed to the Sun. The Earth travels around the Sun because the rotation around its axis gives a forward rotation to the Earth and the slight slanting of the Earth is due to the tiny circular motions of the Sun in its orbit. the Moon rotates around its axis and also around the Sun due to the direct emission of light from the sun and also by the gravitational pull of the Earth towards it. Since the distance between the Moon and Earth is relatively much smaller than the distance between the Sun and Moon , the Moon doesnot move around the Sun independently but rotates around the Sun because of the pull of the Earth which in fact drags it along with it while rotating around the Sun. The Gravity of the Earth is much higher to that of the moon because of the presence of water, air and vegetation on the Earth. In the near future Man will be able create life in the moon by creating the presence Oxygen, carbon dioxide, nitrogen and Hydrogen in the moon which are the basic elements for life, water and vegetation. Utilizing the photon energy , he will be able to move much faster than now in space crafts and even travel through the air and Vacuum without using any transport but with the help of photon emitting sources(devices) By: Simplicius Faustin profsimpu@gmail.com, Mumbai.
