A tachyon (/ ˈ t æ k i ɒ n /) or tachyonic particle is a hypothetical particle that always travels faster than light. Physicists believe that faster-than-light particles cannot exist because they are inconsistent with the known laws of physics.
The special theory of relativity implies that only particles with zero rest mass (i.e., photons) may travel at the speed of light, and that nothing may travel faster. Particles whose speed exceeds that of light ( tachyons ) have been hypothesized, but their existence would violate causality and would imply time travel .
In the Star Trek universe, subspace carries faster-than-light communication (subspace radio) and travel . The Cities in Flight series by James Blish featured ultrawave communications which used the known phenomenon of phase velocity to carry information, a property which in fact is impossible. The limitations of phase velocity beyond the speed ...
A theory of everything (TOE), final theory, ultimate theory, unified field theory, or master theory is a hypothetical singular, all-encompassing, coherent theoretical framework of physics that fully explains and links together all aspects of the universe. [1]: 6 Finding a theory of everything is one of the major unsolved problems in physics. [2 ...
A NASA probe ventured closer to the sun than any spacecraft in history on Christmas Eve — and it whirled by at astounding speeds that also made it the fastest thing ever made by humans. Just ...
As Farnes' theory allows a positive mass (i.e. a ship) to reach a speed equal to the speed of light, it has been dubbed "controversial". [16] If the theory is correct, which has been highly debated in the scientific literature, it would explain dark energy, dark matter, allow closed timelike curves (see time travel ), and suggest that an ...
In physics, a tachyonic field, or simply tachyon, is a quantum field with an imaginary mass. [1] Although tachyonic particles (particles that move faster than light) are a purely hypothetical concept that violate a number of essential physical principles, at least one field with imaginary mass, the Higgs field, is believed to exist.
Here are 10 weird things that can kill you almost instantly. Number 10.A meteor. Humans have been lucky when it comes to avoiding sizeable meteors and mass die-offs. However, if one measuring 50 ...
