Einstein Meets Lemaître

The significance of Lemaître’s work remained mostly unnoticed for three years
Georges Lemaître’s work provided the first interpretation of cosmological redshifts as a natural effect of the universe's expansion within the framework of general relativity. Read More ›

The Men Who Actually Discovered the Big Bang

New book explores the forgotten figures behind one of the greatest scientific discoveries in history.
This book does not exhaustively survey the history of cosmology through the centuries, nor of the few decades that saw the development of relativistic cosmology Read More ›

The New Book on the Big Bang that Roger Penrose is Praising

Meet the forgotten men who discovered evidence for an expanding universe.
Hubble did provide evidence of an expanding universe, but he neither discovered such evidence nor accepted the radical idea that space itself was expanding. Read More ›

Is There Any Evidence That Our Universe Is One of Many?

Philosopher Nancey Murphy recently confessed that she had to adjust her thinking based on the idea that multiverse theory “had progressed.” But has it?
There is plenty of evidence for the fine-tuning of the only universe we know. But, physicist Rob Sheldon says, there is still no evidence for a multiverse. Read More ›

Do New Findings Make Fine-Tuning of the Universe Harder to Deny?

To judge from this episode of Closer to Truth, cosmologists like Alan Guth are finding it harder than ever to rule out intelligent design of the universe
Guth tries explaining away fine-tuning via inflation and string theory but admits that fine-tuning is a “valid explanation” and “our only sensible explanation.” Read More ›

A Physicist Tries to Avoid the Fact of Design in Our Universe…

Physicist Alexander Vilenkin of Tufts University argues, against apparent fine-tuning, that our universe’s cosmological constant should have a special value like zero, but doesn’t

In his discussion with Robert Lawrence Kuhn at Closer to Truth, Tufts physicist and cosmologist Alexander Vilenkin addresses the question, “Is the Universe Fine-Tuned for Life and Mind?”: If the deep laws of the universe had been ever so slightly different human beings wouldn’t, and couldn’t, exist. All explanations of this exquisite fine-tuning, obvious and not-so-obvious, have problems or complexities. Natural or supernatural, that is the question. Vilenkin — who is also a professor of evolutionary science — concedes the main point: Alexander Vilenkin: [0:40] Well yeah that’s right. It appears that the Universe is fine-tuned in the sense that there are about 30 constants of nature which take some specific value: if you look at these numbers, they look Read More ›

Science Wager: Extraterrestrials Will Be Spotted Within 15 Years

An astrobiologist had made the bet with a planetary scientist, after they whittled down ET theories to two possibilities: They’re hiding or they’re not out there
Dirk Schulze-Makuch thinks ET is hiding (the Zoo Hypothesis) but planetary scientist Ian Crawford takes the position that they are just not out there. Read More ›

Five Trends That Help Us Make Sense of Space Science Today

It’s worth keeping all the biases, hopes, uncertainties, and value judgments in mind when we are told that we should “trust the science.” Read More ›

The Search for ET Should Quit Claiming Earth Is Not Special

How will we assess the raw probability of being alone in this universe when we have no other universe to compare with ours?
Earth IS special. The Copernican Principle is false, due to massive evidence of fine-tuning. Of course, that does not show that Earth is unique. Read More ›

Theoretical Physicist Admits That Humans Are Unique

In his forthcoming book, Marcelo Gleiser challenges us to acknowledge our responsibility to save the planet
Gleiser is safer than some near the Third Rail in science —admitting an immaterial reality— because he approaches it under cover of saving the planet. Read More ›

Rogan and Astrophysicist Talk Aliens and UFOs

Are we really the only (intelligent) beings out here?

By David Klinghoffer Our astrophysicist friend Brian Keating from UC San Diego was on the Joe Rogan Experience — for three and a half hours, much as philosopher of science Stephen Meyer was recently. I’ve listened to the whole thing. Very interesting! And with shout-outs to Dr. Meyer on a couple of points that Dr. Keating offers for consideration: that religious faith prepared the way for modern science by teaching the intelligibility and order of nature, and that what really got Galileo in trouble was challenging not the Bible but Aristotle, who had in effect (but not literally) been embraced as a saint by the Catholic Church. Watch and listen here on Spotify.
