Experimental Search for Quantum Gravity
Sabine Hossenfelder “ESQG Summary and Outlook” Talk on 16 July 2010 at the workshop “Experimental Search for Quantum Gravity”, 1216 July, 2010, at Nordita in Stockholm, Sweden. http://www.nordita.org/esqg2010 See Also: Bee Writes:I like this example of neutral Kaon oscillations because … Continue reading

NearFuture PhotonCollider Setups
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
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
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

Gravimetry
For the chemical analysis technique, see Gravimetric analysis. Gravity map of the Southern Ocean around the Antarctic continent AuthorHannes Grobe, AWI This gravity field was computed from seasurface height measurements collected by the US Navy GEOSAT altimeter between March, 1985, … Continue reading

It’s Still A Elephant
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
One of the issues that is evoked by any fasterthanlight 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 fasterthanlight … Continue reading

The Ring of Truth
Savas Dimopoulos:Here’s an analogy to understand this: imagine that our universe is a twodimensional 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?
……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
