Modern Cosmology Makes No Sense, Say Cosmologists

Don’t take our word for it. Cosmologists are banging their heads against the wall.

How the Universe Stopped Making Sense (Live Science). “We’re getting something wrong about the universe,” begins Rafi Letzter after this shocking headline. Measurements in deep space, despite increasing precision, are irreconcilable. The implications are drastic: cosmologists’ most cherished notions, including the cosmic microwave background, might need new physics to be adequately explained. When in trouble, look happy and sound excited.

“People are excited about this because it could mean that there’s new physics, and that would be really exciting,” she [Risa Wechsler] said.

It’s possible that the CMB model is just wrong in some way, and that’s leading to some sort of systematic error in how physicists are understanding the universe.

“Everyone would love that. Physicists love to break their models,” Wechsler said. “But this model works pretty well so far, so my prior is that there has to be pretty strong evidence to convince me.”

What really doesn’t make sense is sounding excited when you have convinced the world that you are the experts, but have been shown to be flat wrong. On this subject at Evolution News, Guillermo Gonzalez, who doesn’t question the big bang and dark energy, discusses the situation in his piece, “A Crisis in Cosmology?”

How Can a Star Be Older Than the Universe? (Space.com). Here’s a challenge: Prove that you are older than your mother. A star named Methuselah is measured to be older than the big bang. When faced with improbability, try moving beyond it into the realm of the impossible.

Taken at face value, the star’s predicted age raised a major problem. How could a star be older than the universe? Or, conversely, how could the universe be younger? It was certainly clear that Methuselah — named in reference to a biblical patriarch who is said to have died aged 969, making him the longest lived of all the figures in the Bible — was old, since the metal-poor subgiant is predominantly made of hydrogen and helium and contains very little iron. It’s composition meant the star must have come into being before iron became commonplace. 

But more than two billion years older than its environment? Surely that is just not possible.

Astronomers are going to have to be creative to solve this “age paradox” the article says. Extensive tweaking of parameters and adjusting of cosmological models might help.

Faster-Than-Light Travel Could Explain Mysterious Signals Beaming Through the Cosmos (Space.com). Nothing is supposed to travel faster than Einstein’s speed limit, the speed of light, but gamma ray bursts give the illusion of doing so. Watch astronomers get creative trying to solve this mystery with several what-if’s and maybe’s.

Dark Matter Update

Exotic ‘Fuzzy’ Dark Matter May Have Created Giant Filaments Across the Early Universe (Space.com). Dark matter, that still-undiscovered mysterious unknown stuff, has always been a fuzzy concept. Maybe the mysterious unknown stuff is fuzzy itself in some exotic way. These speculators speculate with reliance on exotic futureware.

Cesium vapor aids in the search for dark matter (Science Daily). “The hunt for dark matter is one of the most exciting challenges facing fundamental physics in the 21st century,” this article confesses. It’s nice to improve empirical detection methods, but notice that cesium vapor might aid in the “search” for dark matter, not the discovery of it.

We’re waiting for these failed experts to get their act together, but no wise person would wait forever. Get and watch the film below.
