Validating theories...
Two USC researchers have proposed a link between string field theory and quantum mechanics that could open the door to using string field theory -- or a broader version of it, called M-theory -- as the basis of all physics. "This could solve the mystery of where quantum mechanics comes from", said Itzhak Bars, USC…

Imaginary particles. Explaining tangible things...
Tangible products—like a solar-powered hearing aid—may come from not-so-real particles. More particular, scientists analyze the behaviour of modern materials with the help of imaginary structures called quasiparticles. (1) In physics, quasiparticles and collective excitations (which are closely related) are emergent phenomena that occur when a microscopically complicated system such as a solid behaves as if…

Big Bang, universe, logical, illogical.
The big bang poses a big question: if it was indeed the cataclysm that blasted our universe into existence 13.7 billion years ago, what sparked it? Three Perimeter Institute researchers have a new idea about what might have come before the big bang. The problem, as the authors see it, is that the big bang…

This SHOULDN'T exist! [The Kepler-78b case]
Kepler-78b is a planet that shouldn't exist. This scorching lava world circles its star every eight and a half hours at a distance of less than one million miles -- one of the tightest known orbits. According to current theories of planet formation, it couldn't have formed so close to its star, nor could it…

Scientific theories: The illusion of their "progress"
Many people regard "science" as a sector where humans progress constantly. Many people have the wrong idea that new scientific theories "build up" on older existing ones. Scientist lovers are extremely keen on insisting that this fact proves that science is "the way to go" if knowledge is our goal as humans. However the…
