Space Weather News for July 27, 2007

DUST STORM UPDATE: A severe dust storm on Mars, which has been
darkening skies and causing a solar energy crisis for NASA's Mars rovers,
refuses to die down. Clouds of dust are now visible in backyard telescopes
and Mars is beginning to resemble a orange billiard ball as all of its
underlying surface markings are hidden from view. The storm is already
a month old and no one knows when it will subside. Visit
spaceweather.com for photos and status reports.

If there is more than one product, list the metal-atom containing product first. Enter coefficients without a space between the formula and its coefficient, leaving off coefficients of 1 (1 is implied). For hydrated salts, enter the · as a regular period."

Allah The Allmighty says :

( 22-47 ) < And surely a day with your Lord is as a thousand years of what you number.>

It's mean that a Day by Allah is 1000 years in our reckoning in relation with the revolution of the Moon around the Earth ( it is the Hegire year) or the revolution of the Earth around the Sun ( Gregorian year).

And Allah says :

[70.4] To Him ascend the Angels and the Spirit in a day the measure of which is fifty thousand years.


In this verse of the Sura 'The way of Ascent' ( it is the Way which take the Angels from the Earth to the Heaven after having excecuted the duties necessary for the Life of our Planet and the Kosmos. We can note that Allah doesn't say "fifty thousand years of what you number" because the day in question in this verse is a time measure of a Gods day ( which each day is 1000 years in our reckoning ) and this day is the age of the Universe which all events of our life from heaven to earth ascend to Him.

"Graham's number" is really huge but what dangers do we face as human beings playing with numbers that stretch beyond our comprehension ?

What about numbers that are so massive they stretch the limits of the abstract to the point that comprehending their abstract nature becomes itself more of a challenge than comprehending magnitude?

Physicists have suggested that some numbers beyond a certain abstract threshold are in fact so massive just the concept and thought is enough to possess physical mass and it turn a posses a gravitational field.

What do physicists mean by a 13 dimensional number and how can a number posses a physical mass when it is merely a denotation of magnitude?

There is only one known 13 dimensional number, the number 1 villion but this is considerred so unstable it breaks down the laws of quantum reality and can only exists in parallel dimensions at any one time. What dangers to human health does this pose?
