View on the Expansion of the Universe

Posted on August 24, 2005 by PlatoHagel

Georgi Dvali:The cosmic acceleration of the universe indicates that the laws of General Relativity get modified not only at very short but also at very large distances, Dvali says. It is this modification, and not dark energy, that is responsible … Continue reading →

What! Superficiality has extra dimensions to it?

Posted on August 13, 2005 by PlatoHagel

Sometimes I like to play, “knock knock whose there” on my head. :) Quantitative studies of future experiments to be carried out by LHC show that any signatures of missing energy can be used to probe the nature of gravity … Continue reading →

Gravity Leakage: Energy Accounted for in LHC Predictions?

Posted on June 14, 2005 by PlatoHagel

If people were going to do test runs and predictions, how would they fair before the process is up and running? Lubos Motl: What does he say about the cosmological constant? Well, it does not exist. The accelerating expansion of … Continue reading →

G -> H -> … -> SU(3) x SU(2) x U(1) -> SU(3) x U(1).

Posted on April 14, 2005 by PlatoHagel

Here, each arrow represents a symmetry breaking phase transition where matter changes form and the groups – G, H, SU(3), etc. – represent the different types of matter, specifically the symmetries that the matter exhibits and they are associated with … Continue reading →

Curvature Parameters

Posted on December 14, 2004 by PlatoHagel

How does get this intuitive feeling embedded within thinking if it has not grokked the significance on a cosmological scale? When one first begins to comprehend the intuitive possibilities the universe can move through, I was was struck, by the … Continue reading →
