Faster than a speeding photon:
there is no speed limit!!
Travel faster than the speed of light is not forbidden by the laws of physics!
Neutrinos ( subatomic particles wch possess a finite mass) have been clocked traveling faster than the speed of light!
The question of how particles acquire mass is one of the deepest unsolved mysteries of elementary particle physics. Neutrinos had been thought to be the only fundamental constituent of nature which did not have a mass. In light of this discovery, that long-standing belief will have to be revised. However, the Standard Model itself does not "predict" one way or another whether neutrinos have mass - this one of the many parameters of the model which must be input by hand. This is in fact one of the universally recognized shortcomings of the Standard Model, and why most physicists doubt it is the complete, final theory. A truly complete theory would predict the masses of the elementary particles rather than requiring them as inputs.
The effects of the very small neutrino mass implied by the Super-Kamiokande result will probably be minimal in terms of affecting the quantitive predictions of the Standard Model. More promising is the prospect that knowledge of the existence of neutrino masses, and an estimate of their magnitude, will shed light on the larger question of how the particles have the mass that they do. With the discovery of neutrino mass, it now appears that mass is a property common to all matter - in itself a highly significant discovery.

EINSTEIN'S MISTAKES: The human failings of genius
--Hans C. Ohanian
Yeah,but how can an object possessing mass travel faster than the speed of light?....or even as fast?!
ReplyDeleteEinstein said it would take an infinite amount of energy to bring such a particle to the speed of light, and in the process it would become infinitely massive!
...as the speed "v" approaches "c"
ReplyDeleteIn Special Relativity an objects inertia increases as it approaches the speed of light, making it more and more difficult to increase the speed. You could assign this extra inertia to the mass of the object by saying the mass (this is actually called 'relativistic mass' , but I'll call it just mass) increases.
Working this out it turns out the mass increases with a factor \gamma (v). This is a velocity- dependent function increasing to infinity as the speed v approaches c ,thus making it impossible to acquire a speed larger than c.
In SR, time slows down and length is shortened by the same factor!
results confirmed!

Anomalous results clocking
ReplyDelete"faster-than-light" neutrinos may be attributable to a loose fibre optic cable:
Looks like Einstein was right after all!

Built into our brains and our human nature is an innate desire to push the envelope,
ReplyDeletePushing the boundaries of experience drives human evolution and development
It was long considered dogma that the "speed of sound" could not be reached, let alone exceeded!
What seem today to be insurmountable barriers may not be so tomorrow!
