We study the quantum effects of a test Klein-Gordon field in a Vaidya spacetime consisting of a collapsing null shell that forms a Schwazschild black hole, by explicitly obtaining, in a $(1+1)$-dimensional model
Webb's powerful mirrors will allow scientists to look at galaxy formation — including the role of dark matter — up close. While this investigation doesn't directly answer how many galaxies there are in the universe, it does help scientists better understand the processes behind the galaxies we...
But how many weeks are there in a year? Generally, there are 52 weeks and one additional day in a regular year. In a leap year, which occurs almost every four years, there are 52 weeks and two additional days. You may like Groundbreaking atomic clock is off by less than 1 second ...
there's another big differentiator that determines their practicality. Most classical computers are affordable, smaller than a breadbox and able to run in offices and other traditional business environments. Quantum computers, in contrast, are typically car-sized and extremely resource...

“You can have a career in research, or work in industry, but there are so many different quantum technologies that are coming onto the market, at different stages of development. You can work on software or hardware or engineering; you can do communications; you can work on developing ...
There's good reason to believe axions could be real. They're predicted by the theory of quantum chromodynamics, which concerns how the strong force binds quarks together to form protons and neutrons (and hyperons). It also just so happens that axions are a good candidate for dark matter. ...
It seemed pretty clear during OTAs that tight end Darren Waller is destined to be the Giants' No. 1 pass-catcher. The wide receiver position remained murky. Even with Sterling Shepard and Wan'Dale Robinson rehabbing serious knee injuries, there are a lot of ...

In most parts of the world where the GRE general test is administered, the cost is $220, but there are two nations where the price is higher: $228 in Australia and $231.30 in China. The price of GRE Subject Tests is $150 everywhere and won't change despite the impending changes to...
