Not to worry - there will be some other wild new theory of the cosmos next month.

A perfect gas obeys the pv = RT state equation.

'Ya got me, RW. None of the other laws of physics are known to hold inside a black hole, so I'm not sure this one would hold, either. How do you define pressure when the mass of a billion stars has been squeezed down to a mathematical point and the volume is zero? Very, very little of this stuff makes any sense to me. But I love it nonetheless! :-)

You still have p, v, R, and T, but in such abstruse mathematical forms that they don't lend themselves well to mental images. They lost me yesterday with that Lorentz symmetry violation. Diffeomorphism? Serious.

The finding may have spawned a new universal law in physics, which puts constraints on the way fluids behave in the real world.

Congressional Democrats, out of force of habit, are threatening to filibuster the new findings to keep them from becoming law.

Pudding!

They lose me almost every time their lips start flappin', lol. But I still love to think about what they're saying. Yeah, never heard of a diffeomorphism in all my years in math. Doesn't surprise me, tho. A person can only know a teeny, tiny little part of math nowadays.

I'm really restraining myself here!

So, what are the other theorectical dimensions?

And, well, for that matter, what are the three known dimensions?

(Length, height and width/depth?)

The three known dimensions are weight, girth (waist) and inseam.

How about "sight, sound, and mind"? Never mind, that was the Twilight Zone.

The 3 dimensions, scientists hypothesize, run through a 4th dimension, time. Now as to the 5th through 10th dimensions necessary in this fluid black hole theory are a bit beyond my understanding ...though think of space being bent/warped on a micro micro microscopic level that is invisible beyond our technologies but has a dramatic affect on the structure/stability of space-time.

The fourth dimension is the price, with a dollar as unit of measurement.

As far as the new universal law they are talking about, seems to me all the scientists here are really saying is that black holes have less viscosity (ability to move freely through a liquid) than any other object in the universe, if thought about as a liquid. For example,
Water is 60 x's more viscous than a black hole.

They are saying black holes represent the lowest viscosity fluid in the universe and therefore is a constant and tells you the lowest possible limit of viscosity.

Any three mutually orthogonal directions you'd like to choose.

"...the mass of a billion stars has been squeezed down to a mathematical point and the volume is zero..."

A common misconception. The fact is, we don't know what goes on inside the event horizon. The average mass density of a galactic-mass black hole need not be any greater than that of sea-level air.

"everyday is humbling experience when you truly realize how little we know and how insignificant we really are..."

That is how I feel when I watch an eclipse or a comet or a falling star.

Mark Twain

"Courage is resistance to fear, mastery of fear--not absence of fear."

    Samuel Clemens, more commonly known as Mark Twain was born in Florida, Missouri on Nov. 30, 1835. He held many different jobs during his lifetime. Among them, a reporter, a publisher, and a riverboat pilot. In 1862 Sam began writing for many magazines and newspapers under the pen name of Mark Twain, a name taken from a riverboat term. Twain was a great writer, his three best books were Roughing It, The adventures of Tom Sawyer, and The Adventures of Huckleberry Finn.  His books sold many copies. One of his books, A Tramp Abroad  sold 25,000 copies. The year he was born, Halley's Comet passed over. Twain vowed that he would not die until he saw the famous comet. Then, just before he died Halley's Comet passed over. He died the next day; April 21st, 1910, at 6:30 p.m. Mark Twain stopped breathing. (He often said "I came into this world with the comet and I will go out with the comet, and true to his word, the day after Halley's Comet passed over again in 1910, he died)

    Mark Twain was great even during his lifetime. He had many jobs that gave him a good education and varied experiences with many kinds of people. Something else that helped him achieve greatness in the world was that he was determined. He set goals to write his books and set many goals to write magazine articles, newspaper articles and other types of articles. A third thing that helped him achieve greatness was that he had perseverance. That quality helped him write books because he kept on trying to think of varied ways to write his stories and articles. Finally, Mark Twain learned from his experiences. He learned early on that his readers liked different writing styles. He didn't disappoint them when he wrote his humor, satire, and adventure. If his books got bad ratings, he would know not to try something different. Some of his characteristics were integrity, sense-of-humor, and initiative. Mark Twain's personality was funny, out-going, and cooperative. His humorous and insightful remarks were often quoted around the world, both then and now. Mark Twain will be remembered and quoted for a long time.

Once I achieved that perspective I felt a new level of freedom...you have two choices on your path...

Be good...
or
Be bad...

It is much easier to be good...IMHO.
