cant anything achieve a speed faster than the speed of light? WHY?

Question

answer other than theory of relativity, today's physical boundaries
THINK!!WHY CAN'T ANYTHING GO FASTER THAN LIGHT
(time slowing down as we reach speed of light is only relative!!)

Answer 1

Tachyons are thought to.

http://en.wikipedia.org/wiki/Tachyons

A tachyon (from the Greek ταχύς takhús, meaning "swift, fast") is any hypothetical particle that travels at superluminal velocity. The first description of tachyons is attributed to German physicist Arnold Sommerfeld, but it was George Sudarshan[1][2] and Gerald Feinberg[3] (who originally coined the term) in the 1960s who advanced a theoretical framework for their study. Tachyons have recurred in a variety of contexts, such as string theory. In the language of special relativity, a tachyon is a particle with space-like four-momentum and imaginary proper time. A tachyon is constrained to the space-like portion of the energy-momentum graph. Therefore, it can never slow to light speed or below.
And so on.......................

Also Bells inequality suggests the superluminal.

http://en.wikipedia.org/wiki/Bell_Inequality

Bell's theorem is the most famous legacy of the late John Bell. It is notable for showing that the predictions of quantum mechanics (QM) differ from those of intuition. It is simple and elegant, and touches upon fundamental philosophical issues that relate to modern physics. In its simplest form, Bell's theorem states:

No physical theory of local hidden variables can ever reproduce all of the predictions of quantum mechanics.
This theorem has even been called "the most profound in science" (Stapp, 1975). Bell's seminal 1965 paper was entitled "On the Einstein Podolsky Rosen paradox". The Einstein Podolsky Rosen paradox (EPR paradox) assumes local realism, the intuitive notion that particle attributes have definite values independent of the act of observation and that physical effects have a finite propagation speed. Bell showed that local realism leads to a requirement for certain types of phenomena that are not present in quantum mechanics. This requirement is called Bell's inequality.

Different authors subsequently derived similar inequalities, collectively termed Bell inequalities, that also assume local realism. That is, they assume that each quantum-level object has a well defined state that accounts for all its measurable properties and that distant objects do not exchange information faster than the speed of light. These well defined properties are often called hidden variables, the properties that Einstein posited when he stated his famous objection to quantum mechanics: "[God] does not play dice."

The inequalities concern measurements made by observers (often called Alice and Bob) on entangled pairs of particles that have interacted and then separated. Hidden variable assumptions limit the correlation of subsequent measurements of the particles. Bell discovered that under quantum mechanics this correlation limit may be violated. Quantum mechanics lacks local hidden variables associated with individual particles, and so the inequalities do not apply to it. Instead, it predicts correlation due to quantum entanglement of the particles, allowing their state to be well defined only after a measurement is made on either particle. That restriction agrees with the Heisenberg uncertainty principle, one of the most fundamental concepts in quantum mechanics.

Per Bell's theorem, either quantum mechanics or local realism is wrong. Experiments were needed to determine which is correct, but it took many years and many improvements in technology to perform them.

Bell test experiments to date overwhelmingly show that the inequalities of Bell's theorem are violated. This provides empirical evidence against local realism and demonstrates that some of the "spooky action at a distance" suggested by the famous Einstein Podolsky Rosen (EPR) thought experiment do in fact occur. They are also taken as positive evidence in favor of QM. The principle of special relativity is saved by the no-communication theorem, which proves that the observers cannot use the inequality violations to communicate information to each other faster than the speed of light.

John Bell's papers examined both John von Neumann's 1932 proof of the incompatibility of hidden variables with QM and Albert Einstein and his colleagues' seminal 1935 paper on the subject.

Or to use my imagination, as you seem to be asking for.
Matter IS light that is localised, or to put it another way. Light of sufficient energy that comes close enough to a nucleon say will form a pair of particles, possibly an electron/ positron pair. Therefore the electromagetic field of the light is dissociated into its polar fields and localised; visualise it going in a circle when at rest. Now as the velocity of this matter is increased the circle becomes compressed in the direction of travel. Now then it is elliptical and gets flatter and flatter as it aproaches the velocity of light. So the question becomes, why can't light going in a circle go as fast or faster than light going in a straight line? Obviously it can't. Therefore for ordinary matter to equal or exceed the velocity of light is quite impossible in real space-time.

Answer 2

If speed of light is relative then it is possible to go with a speed faster than the speed of light.

Speed of light is not relative; it is absolute; it is constant; it is measured the same whatever the speed of the observer is.

This is the reason that time and distances are relative.

Speed of light is determined by "Distance / the time to cross that distance."

When materials move with the speed of light their distance in the direction of motion becomes zero and time becomes zero.

Now how it will measure the speed of light as some constant. 0/0 is not defined.

Therfore materials cannot move with a speed equal or greater than the speed of light.

Answer 3

To answer your question yes, anything can go past the speed of light. Just like you can go past the speed limit on the highway and just like someone can break a code in some program.

Answer 4

Mass is composed of electromagnetic energy. This is done by the composition of electrons first, then these are formed into neutrons and protons. Mass accelerating to the speed of light converts into electromagnetic energy - of which it is composed.

There is a short writing "The Problem and Repair of Relativity" at http://360.yahoo.com/noddarc that gives more understanding why this is true.

Answer 5

to go at a speed faster than light one needs a huge amount of energy.
even if one can get enough amount of fuel to get the energy, when someone tries to do so, the energy starts getting converted into mass at speeds near to 80% of light.
as mass increases and energy decreases it becomes difficult to increase speed and at a speed of about 98% of light mass becomes so much that speed can not be increased further
hence we can't go faster than light

Answer 6

nothing can achieve the speed of light or faster it because according to prfessor Albert Instien's idea when anything recieve to the speed of light its mass tends to be infinity .

Answer 7

Yes it can go faster .I have seen an experiment shown at I think Max Q or Q max German popular science emission.
There it has been shown how I think electromagnetic Waves can go faster then light.Check that.

Answer 8

being in a speed over lights speed is something that requires alot of energy that todays energy sources is not sufficient for this maby in the future bwith some other energy sources something can reach this speed................

Answer 9

yes for every particle there is an antiparticle. when the spin of the particle changes the spin of its antiparticle changes instantly so you see information has been transmitted faster than light.

Answer 10

not now

the technology is not so advanced yet
