THE END OF GRAVITY:
Kayjatta
Gravity or gravitation is a fundamental force of nature in which objects with mass (and weight) attract one another. Weight is actually the pull of gravity on objects that have mass. This is Newton’s view of gravity and the universe (Newton’s proverbial apple falling to the ground), a view that has been in use for 300 years by lay persons and scientists alike.
However, Newton's conception of gravity has been debunked by Einstein who viewed gravity as "warps (curvature) in space-time”. Einstein’s 1905 paper, Special Relativity, finds gravity in the Newtonian sense troubling and inapplicable; especially in the case of objects (things) that do not have mass, example photons (light particles). Newton is however still relevant in larger objects such as planets.
Now there is a new professor in town, as reported in the New York Times. Dr. Erik Verlinde, a professor of physics and “string theorist” (String theory is a 1980s theory that posits that all matter and energy are made of one –dimensional strings-with only length but no height or width) seeks to change everything with fascinating but controversial evidence that gravity after all does not exist. In his recently published paper on January 6th, 2010; On the Origin of Gravity and the Laws of Newton, Dr. Verlinde of the University of Amsterdam (who recently toured the United States to argue his findings) advanced that “gravity does not exist-as a fundamental force, it is a mere consequence of the laws of thermodynamics” , and that science and scientists have “…been looking at gravity in a wrong way”. This assertion appears consistent with the 1970s findings, of Jacob Bekenstein and Stephen Hawking ,of a strange link between black holes and thermodynamics.
Dr. Verlinde’s new findings have divided physicists across the world with reactions ranging from outright rejection to skepticism and cautious approval. Dr. Strominger of Harvard acknowledged that Professor Verlinde’s findings have “…inspired a lot of interesting discussion”, especially with regards to dark energy (an anti-gravity) and dark matter (stuff that holds galaxies together).
ATTENTION: Kayjatta does not pretend to be a physicist. Other than some college physics, a great fascination with science (and of course his "big mouth" as Moe would say) he has no specialized understanding of many of these things discussed.

KAY.
So" Not an Att." etc, and now," Kayjatta does not pretend to be a physicist"  I know what you are you are a politician
Seriously though,like you stuff such as you have posted here is very interesting to me also, although the people who really know about these things have much more brain power and interlect than I do,however saying that its all theory and there is no proof that is understandable to the average man ,so how do you know that the results that these brilliant minds publish is true,
answer you don't, you have to wait and see if another brilliant mind decides that the first brilliant mind was wrong.
I think that I read somewhere that the string theory was disputed by a "brilliant mind" recently.

Kay, You are of the opinion that the Politicos and schlors will join us and have a chat about this stuff ? what about Moe and Karamba will they post factual things, or can they add to the theoritical levels of brilliant minds? again I am totally unqualifed to take part in discussions, but like you I find it very interesting.  |
"Simple is good" & I strongly dislike politics. You cannot defend the indefensible.

"...a politician"!. But I agree, the "String theory" is controversial, perhaps over-ambitious (seeks to unify Relativity and Quantum Mechanics), and relatively new and unsettled.
I think one scholar has said that all these theorists (Newton, Einstein, and now Verlinde) are broadly talking about the same thing in different ways. In fact one physicist said that Dr. Verlinde is just simply describing the laws of thermodynamics in a different way...
I would like both Moe and Karamba to join in here, Toubab. Perhaps together we will find a "Unified Field Theory" that explains both UDP and APRC adequately. |

"I would like both Moe and Karamba to join in here, Toubab. Perhaps together we will find a "Unified Field Theory" that explains both UDP and APRC adequately."
That discussion would be worth reading if they decide that they would like to post on the SPECIFIC content of your original post or perhaps propose an alternative to your unexplained "Unified Field Theory"
Kay. you have chosen "scholar" in my post as a general word and not a specific one that I intended in my reply 
(not really a puzzle for a man of your interlect ) |
"Simple is good" & I strongly dislike politics. You cannot defend the indefensible.
