Is theory of relativity wrong?
The foundations of relativity (such as the equivalence principle or the relativity principle) are not fictitious, but based on experimental results Also, effects like constancy of the speed of light and relativity of simultaneity are not contradictory, but complementary to one another
Why is the theory of relativity still a theory?
This theory is still considered to be the most important idea in modern physics It rewrote Isaac Newton’s physical laws devised 200 years earlier and created an elegant way to understand the Universe
What is wrong with general relativity?
Yet most researchers think general relativity is wrong incomplete After all, the other forces of nature are governed by quantum physics; gravity alone has stubbornly resisted a quantum description The fix is dark matter, particles invisible to light but endowed with gravity
What Tachyon means?
A tachyon (/ˈtækiɒn/) or tachyonic particle is a hypothetical particle that always travels faster than light Most physicists believe that faster-than-light particles cannot exist because they are not consistent with the known laws of physics
Can neutrinos travel faster than light?
Five different teams of physicists have now independently verified that elusive subatomic particles called neutrinos do not travel faster than light The OPERA team made headlines after they suggested neutrinos traveled faster than light, thus violating Einstein’s theory of special relativity
What is the speed of dark?
Darkness travels at the speed of light More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light
Are neutrinos dark matter?
Neutrinos could be key particles to unravel the nature of the dark matter of the Universe On the one hand, sterile neutrinos in minimal extensions of the Standard Model are excellent dark matter candidates, producing potentially observable signals in the form of a line in the X-ray sky
Why can’t you go faster than the speed of light?
“As objects travel faster and faster, they get heavier and heavier – the heavier they get, the harder it is to achieve acceleration, so you never get to the speed of light,” says Roger Rassool, a physicist at the University of Melbourne, Australia “A photon actually has no mass,” he says
Is C the speed of light?
The speed of light in vacuum is usually denoted by a lowercase c, for “constant” or the Latin celeritas (meaning “swiftness, celerity”) In 1856, Wilhelm Eduard Weber and Rudolf Kohlrausch had used c for a different constant that was later shown to equal √2 times the speed of light in vacuum
Can humans survive the speed of light?
So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans
Are Tachyons real?
Tachyons have never been found in experiments as real particles traveling through the vacuum, but we predict theoretically that tachyon-like objects exist as faster-than-light ‘quasiparticles’ moving through laser-like media
What happens if we travel at the speed of light?
According to the video, if you’re traveling at nearly the speed of light, the clock inside your rocket would show it takes less time to travel to your destination as it would on Earth But, since the clocks at home would be moving at a standard rate you’d return home to everyone else being quite a bit older
