Near-Future Photon-Collider Setups

Posted on April 23, 2012 by PlatoHagel

In the search for a quantum theory of gravity it is crucial to find experimental access to quantum gravitational effects. Since these are expected to be very small at observationally accessible scales it is advantageous to consider processes with no … Continue reading →

Explanation on Quantum Gravity in a Nutshell

Posted on December 14, 2011 by PlatoHagel

Although Aristotle in general had a more empirical and experimental attitude than Plato, modern science did not come into its own until Plato’s Pythagorean confidence in the mathematical nature of the world returned with Kepler, Galileo, and Newton. For instance, … Continue reading →

Holometer

Posted on December 2, 2010 by PlatoHagel

Holometer Revised This plot shows the sensitivity of various experiments to fluctuations in space and time. Horizontal axis is the log of apparatus size (or duration time the speed of light), in meters; vertical axis is the log of the … Continue reading →

It’s Still A Elephant

Posted on November 4, 2010 by PlatoHagel

A sensible reductionist perspective would be something like “objects are completely defined by the states of their components.” The dialogue uses elephants as examples of complex objects, so Rosenberg imagines that we know the state (position and momentum etc.) of … Continue reading →

The Cross Over Point and Time Travel

Posted on May 16, 2009 by PlatoHagel

One of the issues that is evoked by any faster-than-light transport is time paradoxes: causality violations and implications of time travel. As if the faster than light issue wasn’t tough enough, it is possible to construct elaborate scenarios where faster-than-light … Continue reading →

The Ring of Truth

Posted on November 14, 2007 by PlatoHagel

Savas Dimopoulos:Here’s an analogy to understand this: imagine that our universe is a two-dimensional pool table, which you look down on from the third spatial dimension. When the billiard balls collide on the table, they scatter into new trajectories across … Continue reading →

Where Spacetime is flat?

Posted on November 12, 2007 by PlatoHagel

……A Condensative Result exists. Where “energy concentrates” and expresses outward. I mean if I were to put on my eyeglasses, and these glasses were given to a way of seeing this universe, why not look at the whole universe bathed … Continue reading →
