Lessons from Lost Worlds

In The Singular Universe and the Reality of Time Brazilian philosopher, Roberto Unger, and American physicist, Lee Smolin, team up to bring unruly mathematics and fanciful multiverses under control. They seek a renaissance of natural philosophy—ideas—as a driver of future physics. Let’s swing along with them. Central to their thesis is the idea of the […]

A Small Problem

In recent posts we’ve touched upon the sorry state of physics. ‘Sorry state’ is not just my view; many physicists and science writers see this the same way. Physics has now all but lost experimental contact with the real world. What went wrong? How can we fix it? And why should we care? What went […]

Fairy Tales and Physics

These days we all have a stake in physics. It’s not just that physics costs and we, the public, pay. Physics drives our economy. We should be concerned when physicists start writing about how badly it is going. When they write books about this, we should worry. It’s almost a decade since American physicist Lee […]

Making Sense of Space   

Making Sense of Space        Last week we looked closer at the crisis in cosmology. Physicists are inventing increasingly implausible models to describe what they observe. Clinging to descriptions, they abandon understanding. Indeed some heavy-hitter physicists propose to abandon physics. For example, American Nobel-Prize-winning physicist Steven Weinberg says: Now we may be at a new turning […]

Not God―Must Be Goldilocks!

Last week we saw leading physicists seducing themselves into a multiverse. Most accomplished their mental gymnastics in one of three weird ways: a many-worlds interpretation of quantum mechanics; an inflationary cosmology; or a string-theory landscape. All three have in common that they are at best ‘nice ideas’, not physics. So, what’s going on? These physicists […]

Multiverses versus Universe

In the physics stratosphere a great debate is going on. Physicists say it is about the future of physics and the nature of everything.This may be true, but the issues are also personal. The story starts (or so it seems) with multiverses. Not long poems (though those still get more Google hits), I mean multiple-universe […]
