The debris of the 2008TC3 carbonate-meteroite

Arbab Arbab — Tue, 03 Mar 2009 14:25:36 +0000

Remains of 16 pieces of the recent meteorite 2008TC that fell in North Sudan October, 7, 2009 are found by a team from university of Khartoum with collaboration of NASA Ames Center headed by Peter. These pieces are under investigations that will reveal more data about our solar system.

Last week a new compain was launched to explore new areas where the debris of the meteroite might have fallen.

Precession of Mercury and the Larmor precession

Arbab Arbab — Tue, 03 Mar 2009 14:21:14 +0000

Though Newton theory was successful in explaining the motion of celestial objects, it fell short to account for the anomalous precession of the orbit of Mercury( amounting to 43 arcsec/cy). Einstein in his general theory of relativity and by assuming the space-time is curved by the influence of the Sun induces this anomalous precession and in particular forMercury, the closest planet. This interpretation is geometrical in essence. By unifying electrodynamics and gravitation, I have shown that this precession is the analogue of Larmor precession of an electron (a magnetic moment) when placed in a magnetic field. Calculations show that this hypothesis is true, and give the same value as obtained by Einstein. It is s big triumph to Einstein and my hypothesis.

Not only planets but also binary pulsars, which are known to be examples of a system of strong gravity, show a complete agreement with myfinding. We ask the question: Is the space-time really curved, even if we can show these effects without taking into consideration this curvature?

Cosmic acceleration and the planetary acceleration: A modern View

Cosmic acceleration induces planetary aceleration

It might look odd if I say the cosmic acceleration has observable effects on the motion of planets! In a recent study (Astrophysics and Spcace Science, 2008, V.313, 35-39) I have shown that the all planets experience an orbita acceleartion while moving around the sun as a consequence of the cosmic acceleration. Mercury accelerates at a
rate of 12.6 arcsec/cy^2, Venus at a rate of 4.95 arcsec/cy^2, and Earth Earth at a rate of 3.05 arcsec/cy^2 and Mars at a rate of 1.6 arcsec/cy^2. As a result of this their orbits decay with time. The Earth approaches the sun at a present rate of about 20 m/y. The orbital energy that lost is converted in some form of energy, probably gravitational radiation as suggested by Einstein. This point is not yet studied, but under consideration. Why this happens? Since the universe is found to be accelerating, then gravity must increase to offset this ever growing acceleration. In effect, strength of gravity will change (increase) wherebye such effects arise. More is found in the paper at http://www.springerlink.com/content/1187457kk5588550/

Sudan recent meteorite- Sudan Train

Last October, 8, 2008 a meteorite named 2008 TC3 was claimed to be seen by NASA’s Near-Earth Object Project Office falling in North Sudan. However, this event is photographed by a Sudanese source. The fall of this object makes a trace like the old train smoke. It is a fascinating photo. I was one of the team who visited the area that the meteorite is deemed to fall. We could not find any trace. However, next week we will organize a new campaign for finding this meteorite. More reports will be given in due course of time. Look at the amazing photo at http://www.universetoday.com/wp-content/uploads/2008/11/2008tc3train7_elhassan.jpg

The Sudanese Physicists: Me

admin — Tue, 30 Sep 2008 11:12:46 +0000

Hi Every body,

I am a Sudanese physicist interested in cosmology and astrophysics. I have written several research papers related to the earth-moon-sun system from a cosmological point of view. I have recently shifted my interest to study the unification of electromagnetism with gravity and hydrodynamics. In doing so we have shown that Euler, Maxwell and Newton equations are equivalent in form. Larmor precession, vorticity, curvature and magnetic fields are all one aspect of different phenomena. They arise whenever a field experiences a mass, charge, obstacle during its propagation.
