(Phys.org) —Cosmologist Christof Wetterich of the University of Heidelberg has uploaded a paper to the arXiv server in which he claims it's possible that the theory of expansion of the universe might be incorrect. He suggests ...
High-energy neutrinos are highly fascinating subatomic particles produced when very fast charged particles collide with other particles or photons. IceCube, a renowned neutrino detector located at the South Pole, has been ...
Conventional wisdom would say that blocking a hole would prevent light from going through it, but Princeton University engineers have discovered the opposite to be true. A research team has found that placing a metal cap ...
