The elegance of Physics

Post by kojikun »

I was just reading through some posts in OSF, someone mentioned blackholes and such, and I began to think "why cant we create a black hole only with electromagnetic force isntead of gravity?". Thinking it through i realised the only real reason is because like-charges repel and before you got any sufficient amount of electrons or protons in only place the thing would blow itself apart.

Then I realised something. For the longest time I had been thinking "yanno, why isnt there a force where likes attract?" and I realised, there IS: Gravity. Ofcourse theres only one gravitational "charge" that we humans know of, but thats moot. I began to then think over the reasons why gravity is so weak and such.

It dawned on me that the universe has an elegance about it. Electrical charges are just perfect for the kind of matter we're familiar with, any different and the whole thing would be changed. Gravity is so weak, weak enough to not cause humans to scrunch into a tiny infinitely dense ball of nothing because our bodies are trying to pull themselves together. The strong nuclear force is perfect for holding protons and neutrons together into particles, without relying on orbitals and such in the way atoms do.

The universe is a damned elegant place. The number of times things had to replay themselves over and over to come up with this beautiful assortment of physical laws is staggering, but its damned amazing.

And no, Im not high :)

I agree. I get the same feeling studying the Fibonacci numbers and moreso the ratios between them. Truly, an amazing place.

Yup, thats why I always laugh when some idiot trys to convert me with the miracles of Jesus or some other. All I have to think is the great and amazing things that the real universe has to offer instead of the Biblical universe.

*ahem
Gravity is weak because of, according to string theorists and others, the energy involved is flowing into other dimentions. They've demonstrated that certain dimentions, occuring only between objects less than a millimeter apart, put out a good deal more gravitational force, than would be possible if space were purely 3 dimentional+time.
One experiment is taking two thin flat plates with equal masses and diameters, with a number of holes cut out one exactly like the other are suspended appart roughly a millimeter. One is spinning slowly and the other is static but has an accleration detector(ball suspended from a string). When all the holes are in perfect alignment, the ball jiggles. This is because the gravitational force was at its greatest at that particular instant and induced kinetic movement.
In place of a ball on a string you could always use an instrument to check the amount of torque applied on shaft spinning the plate.

According to string theory, gravity is weak because gravitons have extremely high tension, so the force they can transmit is tiny. Strings that have extremely high tension are called gravitons because gravity is weak. If you found a better explanation, someone deserves a nobel prize.

Are you sure it isn't simply another version of the Casimir effect?

In a vacuum?

A better question would be: has this effect been sucessfully replicated in several, independent, laboratories?

Oh, yes, quite. It's just that changes in the airflow would be the most plausible explanation.

The only situation I know of where gravity becomes exceedingly strong is quantum gravitational effects occuring at EXTREMELY small scales. They plan on using the uber strength of gravity at such ridiculously tiny distances to create micro black holes.

"They" strike again! We should really begin to worry about this scary unseen organisation and what "they" are doing with all this technology and occult research "they" appear to be doing.

Worry people! The End is nigh!
