Faster than light particles found, claim scientists

[rohitshubham]

it can change since it changes the understanding of speed who knows how many elements are faster than light

well the classical mechanics wont change for sure.... but the modern physics will undergo a massive transition .... the Maxwell's laws would be irrelevant and this forms the base of Einstein's equation...this is something if true would change the world of not only physics but chemistry too as we would get mechanisms of many reactions like reimerr-teimerr ...whose transition state is not even detected by the femtometer

hehe,I am not god,I really don't know what light means and look like,just know brightness and darkness in appearance.

well you might have taken commerce for sure.... because even a basic student of physics knows about light

maxwell wont change. hell, even ray optics from 400 years ago still works for many situations. maxwell's EM is still going to be a highly useful tool for EM studies both in vacuum and in medium.

God said 'Let there be light' and there was light.Is the word god had said has same meaning with that using in Physics?

Electro Magnetics is one area where humans can safely claim to have uncovered mostly everything...

 

[OrionHunter]

tachyon anyone?

Tachyons are hypothetical particles. But neutrinos have almost been proved to exist. We'll know after a couple of more confirmatory experiments scheduled to be conducted in the coming months.

And if it's discovered that particles can travel FTL then that would change the very paradigms of science as we know it!

Depends upon ur religious and scientific views

'light' is just a common term for photons. Photons are packets of energy and the speed at which they travel in vacuum is called the speed of light.

In physics, all the forces between matter particles -- from magnetism to electrostatic to weak to strong force -- are assumed to be transmitted by photons. So when you hold a magnet over your keys, the two objects trade photons back and forth.

Although Einstein is silent on the matter, it is assumed that gravity also propagates at the speed of light. In fact, it is one of the favorite attack points of people trying to disprove relativity. The sun's light takes 8'20 minutes to get to Earth and the question arises: are we revolving around the sun as it is right now, or where it was 8'20 minutes ago?

Since no physical process can occur faster than the speed of light, it is, in some sense, the speed of time.

Well, I saw this research on Discovery one day. They are actually making a machine with which they can accelerate these particles faster then light so that they can transmit it in past. In past there will be a machine that can receive these particles.

And so by sending and receiving these particles they can actually transmit signals to people in past and inform them of some Natural disaster and can avoid many adversities...

Yeah... but there is a subtle difference. The quantums are different for different forces. Eg. gravitons for gravity and electrons for charge (electro magnetic force) etc. Ever since maxwell unified electric and magnetic forces there has been serious research towards unifying all forces of nature. The M- Theory holds promise for the future...

Are u sure ? can u give me some links or anything.... coz AFAIK some scientists have claimed that the concept of Time Machine will violate the most fundamental concepts of physics which have been thoroughly proved. (again i dont have link for my claim but google will return something )

we already know that ordinary matter, that is to say atoms composed of neutrons, protons and electrons, cannot accelerate faster than light, and therefore assemblies of atoms like solids, liquids and gases also cannot. therefore its useless because for all intents and purposes nothing built by humans can ever travel faster than light.

a neutrino is, from what i read, a massless, chargeless particle that does not interact with ordinary matter much and is nearly indetectable; it is generated by obscure processes in nuclear reactions and it is essentially useless in engineering applications.



actually, Newtonian physics is the most commonly used physics by far. relativity has very obscure and niche applications. quantum mechanics is highly useful for electronics, advanced materials and telecommunications, but this isn't as much as Newtonian mechanics which can even be used as approximations for simulating chemical systems, whereas a quantum simulation of say... a rocket, would be useless.

Slightly wrong - neutrinos do have mass - though a small one
Neutrino Mass
and if an object (having mass) can travel faster than light then it stands to logic that other particles like electrons,protons and atoms in general can too - proving einstein wrong

Electrons are not the carriers of electromagnetic force. It is still transmitted through photons.

As for gravitons, that's just theory at this point. Relativity obviates the need for gravitons but it doesn't offer any explanation of how gravity propagates.

Ever since maxwell unified electric and magnetic forces there has been serious research towards unifying all forces of nature. The M- Theory holds promise for the future...

I don't buy M-theory. It is nothing more than a bunch of unprovable formulas on paper, which makes it equivalent to philosophy. Basically, it's just a fancy mathematical game for physicists to see if they can balance the equations. When in doubt, throw in an extra dimension or two. Or 11.

Wow,the speed of time,and speed is a concept just with time in it.Is our world build upon concepts combining concepts?

Well, if you want to be really blown away, consider the concept of block time.

In this theory, since time is just another dimension like the other three, we can assume that it already exists in the past and future. For an analogy, consider the physical dimensions: even if you are standing in China, America and Australia still exist. Just because you are not physically standing in America or Australia doesn't mean they are not there. By that logic, past and present already exist out there in spacetime. Our perception of time is nothing more than our consciusness travelling along an existing time axis.

one of my school physics teacher was too much into theoratical physics......so much that later went mad and had to be treated for mental illness..he eventually recovered...both from mental illness and obsession with theoratical physics..
He once said that speed of light is not a unversal constant....instead its a contant for a galaxy.....depending on overall mass and gravity of a galaxy...speed of light will be different for different galaxies....
