BIG BANG THEORY

The Big Bang theory is the prevailing scientific model for the origin of the universe. It suggests that the universe began as a singularity, an infinitely small and dense point, around 13.8 billion years ago. This singularity then rapidly expanded and cooled, leading to the formation of the universe as we know it today. There are several different variations of the Big Bang theory, but they all share the basic idea that the universe began in a hot, dense state and has been expanding and cooling ever since. The most widely accepted model is the Lambda-CDM model, which includes the ideas of cosmic inflation (a brief period of extremely rapid expansion in the early universe) and dark matter (an invisible form of matter that makes up most of the mass in the universe). Despite its overwhelming scientific support, the Big Bang theory is still the subject of ongoing research and debate. Some alternative models have been proposed, such as the steady state theory and the cyclic model, but they have not gained widespread acceptance.

Physicists observe a new form of magnetism for the first time

MIT physicists have demonstrated a new form of magnetism that could one day be harnessed to build faster, denser, and less power-hungry " spintronic " memory chips. The new magnetic state is a mash-up of two main forms of magnetism: the ferromagnetism of everyday fridge magnets and compass needles, and antiferromagnetism, in which materials have magnetic properties at the microscale yet are not macroscopically magnetized. Now, the MIT team has demonstrated a new form of magnetism , termed "p-wave magnetism." Physicists have long observed that electrons of atoms in regular ferromagnets share the same orientation of "spin," like so many tiny compasses pointing in the same direction. This spin alignment generates a magnetic field, which gives a ferromagnet its inherent magnetism. Electrons belonging to magnetic atoms in an antiferromagnet also have spin, although these spins alternate, with electrons orbiting neighboring atoms aligning their spins antiparalle...

Physicists Catch Light in 'Imaginary Time' in Scientific First

For the first time, researchers have seen how light behaves during a mysterious phenomenon called 'imaginary time '. When you shine light through almost any transparent material, the gridlock of electromagnetic fields that make up the atomic alleys and side streets will add a significant amount of time to each photon's commute. This delay can tell physicists a lot about how light scatters, revealing details about the matrix of material the photons must navigate. Yet until now, one trick up the theorist's sleeve for measuring light's journey invoking imaginary time has not been fully understood in practical terms. An experiment conducted by University of Maryland physicists Isabella Giovannelli and Steven Anlage has now revealed precisely what pulses of microwave radiation (a type of light that exists outside the visible spectrum) do while experiencing imaginary time inside a roundabout of cables. Their work also demonstrates how imaginary numbers can describe a ver...
