Are the Laws of Nature the Same Everywhere in the Universe?

Although we haven't figured out everything in the universe by a long shot, we're getting a pretty good a handle on how things work in our world, and how the laws of nature operate here at home. One big question we have is, would laws of nature as we know them function the same at other locations in the universe? A new study says, yes.

Rachel, maybe it was a supernova. I've never seen one myself, but I hear they're pretty bright if you're lucky enough to see one. Some of these other comments are downright crazy. I really don't know how to…

Key to All Optical Illusions Discovered

Humans can see into the future, says a cognitive scientist. It’s nothing like the alleged predictive powers of Nostradamus, but we do get a glimpse of events one-tenth of a second before they occur.

Here's how the foresight theory could explain the most common visual illusions — geometric illusions that involve shapes: Something called the Hering illusion, for instance, looks like bike spokes around a central point, with…

Ask Calvins Dad

Calvin’s Dad often makes up outlandish answers to Calvin’s questions. Here is a collection of some quotes from the comic strip.

Q. How come old photographs are always black and white? Didn’t they have color film back then? A. Sure they did. In fact, those old photographs are in color. It’s just that the world was black and white then. The world…

2012: No Planet X

Apparently, Planet X (a.k.a. Nibiru) was spotted by astronomers in the early 1980’s in the outermost reaches of the Solar System. So what does this mean to us? Millions, even billions of people will die, global warming will increase; earthquakes, draught, famine, wars, social collapse, even killer solar flares will be caused by Nibiru blasting…

Pulling up the discovery of planets using orbital perturbation measurements, Planet X advocates point to a NASA announcement that in 1992, there were indirect measurements of a planet some 7 billion miles from Earth. Alas, I cannot find the…

Did Earth once have multiple moons?

The ancient catastrophe that gave birth to the Moon may have produced additional satellites that lingered in Earth’s skies for tens of millions of years.

Separate modelling work by Matija Cuk, an astrophysicist at the University of British Columbia in Canada, suggests small, asteroid-sized objects a few tens of kilometres across would have lasted the longest as Trojan satellites. Cuk estimates…

Memristor ,the "missing link" in electronic circuit theory, has been invented by Hewlett Packard

The long-sought after memristor–the “missing link” in electronic circuit theory–has been invented by Hewlett Packard Senior Fellow R. Stanley Williams at HP Labs (Palo Alto, Calif.). Now virtually every electronics textbook will have to be revised to include the memristor and the new paradigm it represents for electronic circuit theory.

Physics: Quantum all the way

How does our classical world emerge from the counterintuitive principles of quantum theory? Can we even be sure that the world doesn’t ‘go quantum’ when no one is watching?

The decoherence description shows that there is no abrupt boundary, no critical size, at which quantum behaviour switches to classical. And that blurry boundary itself shifts depending on how it is measured. It is the choice of the measuring…

The Paranoid Style in American Science

Radical skepticism and the rise of conspiratorial thinking about science.

The proponents of intelligent design are far from the only critics of mainstream science whose skepticism has taken on the trappings of conspiracy theory. In a 2005 article for Salon and Rolling Stone, Robert F. Kennedy Jr. reported on a…

15 Answers to Creationist Nonsense

Opponents of evolution want to make a place for creationism by tearing down real science, but their arguments don’t hold up. The following list rebuts some of the most common “scientific” arguments raised against evolution.

When Charles Darwin introduced the theory of evolution through natural selection 143 years ago, the scientists of the day argued over it fiercely, but the massing evidence from paleontology, genetics, zoology, molecular biology and other fields…

PZ Myers on Newtonism

A satire on intelligent design logic. “How many have died due to the tyranny of the gravity Newton put into the hands of conscienceless materialist scientists? Examine Hitler’s record, for instance. He was an ardent Newtonist who put his Wehrmacht to evil purpose, building machines that used the wicked geometries of Newton to shatter Europe.

Although the parody is funny, I'm not sure it works that well. This is what Matthis said in defense of Expelled : “If this debate were really just about scientific ideas-when was the last time you heard about people getting together…
