Gravimetry
Gravity map of the Southern Ocean around the Antarctic continentThis gravity field was computed from sea-surface height measurements collected by the US Navy GEOSAT altimeter between March, 1985, and January, 1990. The high density GEOSAT Geodetic Mission data that lie south of 30 deg. S were declassified by the Navy in May of 1992 and…

What are Memories made up of ?
Illustration by The New York Times Some do indeed understand the fuzzy logic. These images are pixel orientated. They describe a process of thinking that is quite impermeable to the everyday biological function of the thinking brain that we have devised a way in which to represent the process of marketing for the populace at…

Tunnelling in Faster then Light
Underneath this speculation of mine is the geometrical inclination of the universe in expression. If it’s “dynamical nature is revealed” what allows us to think of why this universe at this time and junction, should be flat(?) according to the time of this universe in expression? Omega=the actual density to the critical density If we…

Result of Effective Changes in the Cosmos
“There comes a time when the mind takes a higher plane of knowledge but can never prove how it got there. All great discoveries have involved such a leap. The important thing is not to stop questioning.” Albert Einstein (1879- 1955) But the presence of an event horizon implies a finite Hawking temperature and the…

Graviton in a Can?
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 “perfect fluid/soup” we find that certain aspects of the reductionist work done, has indeed lead…

Lisa Randall on Xtra Dimensions
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 (3 + 1)-dimensional brane or branes. The models were proposed in 1999 by Lisa Randall…

Box Counting or "Points" on the Strings Length?
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 of General Relativity. Thus General Relativity may be viewed as a prediction of string theory!…

Beyond Spacetime?
As well as bringing the accelerator’s counter-rotating beams together, LHC insertion magnets also have to separate them after collision. This is the job of dedicated separators, and the US Brookhaven Laboratory is developing superconducting magnets for this purpose. Brookhaven is drawing on its experience of building the Relativistic Heavy Ion Collider (RHIC), which like the…

String Theory Landscape
The theory of strings predicts that the universe might occupy one random “valley” out of a virtually infinite selection of valleys in a vast landscape of possibilities Quantum Effect, however allow a manifold to change state abruptly at some point-to tunnel through the intervening ridge to a nearby lower valley. By Raphael Bousso and Joseph…
