Can anything go faster than the speed of light?
Can anything go faster than the speed of light?
light is as fast as we can measure speed any faster and we can’t measure how fast it is because its partials are moving so fast their invisible and can go through anything including light so its invisible to everything
P.S I’m 13 years old and got many theories about many thing email me @ tywos @ hotmail.com
Speedy Gonzonas
Actual what is sad is someone who takes life so seriously that they can’t enjoy a joke to lighten up the mood of everyday life. . .
paradise: “The Universe itself, Spacetime can expand much faster then light itself.”
There is no proof or even evidence that the Universe expanded faster than the speed of light. The expanding universe ‘assumption’ was made because the old assumption violated the laws of physics, namely the law of inertia and the anomaly that we can somehow see supposedly billions of years into the past with a telescope. The redshift model could just as easily and more plausibly be explained by a ‘rotating’ universe. The planets in our solar system do not revolve around our sun keeping the exact same distance between them! Why should we think it is any different with the galaxies and the universe as a whole?
The speed of sound
New experiments show that some things can travel faster than the speed of light.
But the Universe always manages to ensure that we can never use the effect for anything useful, like building a faster-than-light starship or travelling back in time.
It is a fundamental law of physics, a fact that is built into the architecture of the Universe and taught to every student, that nothing can travel faster than light which is roughly 300,000 km a second (186,000 miles).
Well not exactly. The Universe does have this speed limit but recent experiments would seem to suggest that in certain circumstances something can travel a bit quicker.
According to Einstein’s special theory of relativity, a faster-than-light signal would violate the “causality principle,” which states that “causes” always precede “effects.”
The recent experiments are not especially new. Physicists have been making light pulses that travel faster than c (the speed of light in a vacuum) for years. They key point however, is that none of the experiments could be used to send information faster than c.
Difficult experiments
In one experiment, led by Anedio Ranfagni, of the Italian National Research Council, microwaves were sent through a narrow, ring-shaped opening onto a large mirror, sent the waves back to and behind the source. The arrival times of these pulses showed that they travelled at speeds 5% above c.
The work is described in a recent issue of the Physical Review Letters.
But some researchers say the effect may be an illusion caused by light taking a shorter route through the optical system than expected. However, the Italian researchers do not believe this and say there is a “a shadow of a doubt” about faster than light effects.
In the other experiment, a pulse of light that enters a transparent chamber filled with caesium gas reaches speeds 300 times the normal speed of light.
According to the researchers, the main part of the light pulse leaves the far side of the chamber even before it enters at the near side!
A research paper on the experiment, by Lijun Wang of the NEC Research Institute in Princeton, US, is reported to have been submitted to a major science journal, though it remains to be seen how far it will get.
Flashing lights
There is some debate about these type of experiments because they are very difficult to do and could be plagued by many unknown errors. Most physicists would say they are interesting but that in every case there will be a loophole that will allow nature to protect the causality effect.
For years, scientists have been gathering evidence of faster than light, so-called superluminal, phenomenon.
On a simple level, a flashing row of lights can display signals that move from one end of the row to the other end faster than c if the lights flash on and off in time.
But scientists point out that the effect is an illusion and that nothing physical is travelling faster than c.
In space, some 20 years ago, astronomers were puzzled, briefly, by distant objects that appeared to go faster than c.
The explanation was that when an explosion occurs at speeds comparable to c then it can appear from the outside that the lightspeed limit is being violated.

yes, there is a such thing as warp speed. And no im not a fan of star trek or star wars. But its a proven fact that time slows down the faster you travel, its all physics, look it up sometime. So I believe that there must be a warp speed. When you travel fast enough time stops. It just makes sense, the only problem is handling the G forces
Superman
Oh yeah… Superman can PUNCH back in time…
Yeah…remember, he just has to fly around the globe backwards really fast…DUH!!
To jasraj10: What are you taking about?
no because if we did there would be no light
LOL at some of the other comments. The Speed of Light is the fastest
“ warp drive “ on Star Trek’s Enteprise space ship :-)
i hope you know you spelled Speedy Gonzales wrong, rnealw

Figures. . . . My Spanish never was that good. . .
The speed of sound
I… hope you’re joking…
No as proven by elbert einstien
what 8 ball said just not as elaborat XD
well I dont know about this exactly but shouldnt the speed of light be equivalent to the speed of dark, lol but im serious about that comment.
It’s sad that people are making jokes out of this question, especially Advisors, Speedy Gonzales? The Universe itself, Spacetime can expand much faster then light itself.
speed of dark… I turned off the lights in my bedroom and let me tell you, that dark is quick!! lol or superman, he is faster then anything.
no the speed of light is the fastest.
neutrinos may be able to handle this impossible task.
