Cosmic ray spallation

Posted on December 20, 2006 by PlatoHagel

As this NASA chart indicates, 70 percent or more of the universe consists of dark energy, about which we know next to nothing Other explanations of dark energy, called “quintessence,” originate from theoretical high-energy physics. In addition to baryons, photons, … Continue reading →

Against Symmetry

Posted on December 14, 2006 by PlatoHagel

The term “symmetry” derives from the Greek words sun (meaning ‘with’ or ‘together’) and metron (‘measure’), yielding summetria, and originally indicated a relation of commensurability (such is the meaning codified in Euclid’s Elements for example). It quickly acquired a further, … Continue reading →

Graviton in a Can?

Posted on November 12, 2006 by PlatoHagel

After you consume “graviton in a can,” you might never be the same? Brane thinking may then dominate your every view of the world. Then, it will all make sense? Imagine while we peer deeper into the subject of the … Continue reading →

Lisa Randall on Xtra Dimensions

Posted on November 10, 2006 by PlatoHagel

In physics, Randall-Sundrum models imagine that the real world is a higher-dimensional Universe described by warped geometry. More concretely, our Universe is a five-dimensional anti de Sitter space and the elementary particles except for the graviton are localized on a … Continue reading →

The Radius of the Little Circle

Posted on October 23, 2006 by PlatoHagel

Where a dictionary proceeds in a circular manner, defining a word by reference to another, the basic concepts of mathematics are infinitely closer to an indecomposable element”, a kind of elementary particle” of thought with a minimal amount of ambiguity … Continue reading →

Box Counting or "Points" on the Strings Length?

Posted on October 9, 2006 by PlatoHagel

The jump from conventional field theories of point-like objects to a theory of one-dimensional objects has striking implications. The vibration spectrum of the string contains a massless spin-2 particle: the graviton. Its long wavelength interactions are described by Einstein’s theory … Continue reading →

CP Violation

Posted on October 2, 2006 by PlatoHagel

The value of non-Euclidean geometry lies in its ability to liberate us from preconceived ideas in preparation for the time when exploration of physical laws might demand some geometry other than the Euclidean. Bernhard Riemann ON a macroscale the blackhole … Continue reading →

Gravity-Don’t Let it Get You Down

Posted on September 27, 2006 by PlatoHagel

If a inkblot appears on your desk, would you think it appeared in the shape it did to convince you, that what you are “seeing is real?” To you, it may look like someone trying in their attempts to convince … Continue reading →

Why do physicists want to study particles?

Posted on September 26, 2006 by PlatoHagel

A few “cosmic rays” pass through our body every second of every day, regardless of where we are. They consist of particles created when high energy atomic nuclei (mainly protons) coming from outer space collide with the atoms at the … Continue reading →

A Distorted Lense?

Posted on September 25, 2006 by PlatoHagel

Gravity dominates the large-scale structure of the universe, but only by default, so to speak. Matter arranges itself to cancel electromagnetism, and the strong and weak forces are intrinsically short range. At a more fundamental level, gravity is extravagantly feeble. … Continue reading →
