Double Trouble for Cosmology

Two developments are converging to threaten the standard big bang model of the universe's origin.

More Cosmic Fine-Tuning Found

The Anthropic Principle refuses to go away. The mass of the light quark adds to finely tuned factors that make the universe life-supporting.

Of Stars and Significance

The farther out we look, the more questions we have. But does secular astronomy ask the right questions?

Big Bang's Lithium Problem Gets More Problematic

There's no escape; new measurements show far less lithium than predicted by the big bang, and more fine tuning than would be expected by chance.

Inflation Concocted to Avoid a Young, Perfect Universe

Alan Guth concocted inflation theory in 1980 to avoid evidence for a 10,000-year-old universe. For his wild, evidence-free speculation, he may win a Nobel Prize.

Archive Classic: State of the Cosmos 2005: Alan Guth Explains Inflation

As Alan Guth rises to prominence this year for his inflation proposal, it might be useful for readers to see what he said about it in 2005.

Existence of Universe Is Highly Improbable

Theologians might rightly celebrate a recognition by cosmologists that the universe is so finely-tuned, it shouldn't exist.

Light Speed Implications Are Staggering

A new paper revises the speed of light. This could change everything in the universe.

Cosmic Inflation Proof Is on the Ropes

The highly-acclaimed evidence of inflation theory announced in March may only be a signal from local dust.

Galaxy Evolution Problem: A Case Study in Criticizing Paradigms

"When you have a clear contradiction like this, you ought to focus on it," say scientists who found problems with the leading theory of galaxy evolution.

Antimatter Conundrum Remains After Precision Test

Why isn't the universe half ordinary matter and half antimatter? Both should have emerged from a big bang.

Cosmology Goes Off the Reservation

If science were ever restricted to observation, experimental demonstration, and evidence, some cosmologists left that reservation far behind long ago. Being smart does not preclude going nutty.

Big Bang "Breakthrough" May Be False

Criticisms of the BICEP2 announcement are coming in, and could overturn the highly-publicized announcement that "inflation" has been discovered.

Young Galaxy Mature for Its Age

Remote galaxy that should be young looks well-behaved and mature, "truly surprising" astronomers.

Has Cosmic Inflation Been Discovered?

Claims of a major breakthrough about the big bang are swirling in the news: is it inflation, or inflating the evidence?
