If $|\\lambda|$ approaches infinity\nasymptotically, the universe does not exhibit an acceleration at late times. In\nthis case, however, we find an interesting possibility that a transient\nacceleration occurs in a regime where $|\\lambda|$ is smaller than of order\nunity.Edmund J ...
Four dimensional Einstein equation with non-vanishing energy momentum tensor is solved to give a solution where the event horizon of a celestial body is outside of the body, which corresponds to a black hole by definition. There is no singularity at the center of the object unlike the case ...
Which is the fastest particle in the universe? 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 physic...
What is the earliest time from which we observe light in the universe? Dose light travel faster through the lower atmosphere or through the upper atmosphere? Given the fact that light travels at c, can it have mass? Explain. Does light itself have infinite energy or does it eventually decele...
The dominating form of energy in the cosmos dark energy is driving the accelerating expansion of the universe, but its nature remains a mystery.

—Tachyons: Facts about these faster-than-light particles —What are bosons? —What are neutrinos? The Coulomb force is the electrostatic force felt by like charges — the positive charges of the protons in one atomic nucleus will repel the positive charges of the protons in the other atomi...
