The Strong Force Is What’s Holding the Entire Universe Together
Posted by Quinn Sena in category: particle physics
Particle physicists might seem like a dry bunch, but they have their fun. Why else would there be such a thing as a “strange quark”? When it comes to the fundamental nuclear forces, though, they don’t mess around: the strongest force in nature is known simply as the “strong force,” and it’s the force that literally holds existence together.

It took centuries, but we now know the size of the Universe
Posted by Quinn Sena in category: space
We can never see these more distant regions. Still, the observable Universe alone should be big enough for most people. Indeed, for scientists like Casey and Sheth, it remains a constant source of fascination.
We’re not even at the centre of our Solar System or at the centre of our galaxy
“Everything that we’ve learned about the Universe – how big it is, all the amazing objects that are in it – we do that simply by collecting these photons of light that have travelled millions and millions of light years only to come and die on our detectors, our cameras or radio telescopes,” says Sheth.

Robert Steinhaus’s answer to How small can a fusion reactor be?
Posted by Quinn Sena in categories: futurism, nuclear energy
Small fusion is very possible as fusion is a nuclear process that scales elegantly.
Sometime in the not distant future that we may see the practical development of successful small fusion reactors. Even integrated circuit scale pure fusion reactors may be possible.

Study says gravity and Higgs boson interacted to save the universe
Posted by Quinn Sena in category: cosmology
Circa 2014
One second after the Big Bang, the Higgs boson should have caused a Big Crunch, collapsing the universe to nothing. But gravity saved the day.

Physicists create world’s first multiverse of universes in the lab
Posted by Quinn Sena in categories: cosmology, nanotechnology, physics
Researchers at the University of Maryland, College Park and Towson University are reporting that they have created multiple universes inside a laboratory-created multiverse — a world first.
To be exact, the researchers created a metamaterial — like those used to fashion invisibility cloaks — that, when light passes through it, multiple universes are formed within it. These universes, called Minkowski spacetimes, are similar to our own, except they more neatly tie up Einstein’s theory of special relativity by including time as a fourth dimension.
While this is rather extraordinary, the experimental setup is actually quite simple — though definitely rather unconventional. The multiverse is created inside a solution of cobalt in kerosene. This fluid isn’t usually considered a metamaterial, but lead researcher Igor Smolyaninov and co found that by applying a magnetic field, the ferromagnetic nanoparticles of cobalt line up in neat columns. When light passes through these columns, it behaves as if it’s in a Minkowski universe.
