I hear ya! A hot smarty! or a smart hotty! Niiiiice!

Einstein rejected it because it did not pass the reality test.

Now that reality has entered the equation, I'm totally confused.

The "braneworld universe" has five dimensions -- four spatial dimensions plus time -- compared with the four dimensions -- three spatial, plus time -- laid out in the General Theory of Relativity.

I was just thinking about that this morning

[BeHoldAPaleHorse]

To quote Master Yoda:

"Hit it I would!"

[BeHoldAPaleHorse]

These clowns are bush league compared to Buckaroo Banzai.

Buckaroo Banzai explains the Universe:

"No matter where you go, there you are."

[Huck]

I don't know. Something about imagining the Universe as a slice of bread, with other Universes(slices) "next" to it. But all that does is place the Universes inside a larger 3D construct (the loaf of bread), and fails to explain where the loaf resides. Infinity is the ultimate wig-flipper. No matter how far out you go, can't you go a little farther? No matter how big (or small) something is, couldn't it be just a bit bigger (or smaller)? My dad (a physicist) taught me infinity when I was a young boy. He had me stand a few feet from the wall, told me to go half the distance to the wall, and then do it again, and again, halving the distance to the wall, and to tell him when I got there.

Oh man, she can theorize my space/time continuum any day :-PPP

[DCPatriot]

But a cube has six sides...not four.

[Not A Snowbird]

I listed to Chuck Misler try to explain four dimensions once and my head nearly exploded.

Supposedly it's height, width, depth, and breadth, but darned if I can explain it. I'll just have to take his word for it.

[JustDoItAlways]

At least there is a proposal to test/detect proof for the theory.

But manipulating/controlling gravity should be the ultimate aim.

[joem15]

No, it boggles my wallet. The hapless taxpayer is paying for all of these brain farts let go by the wunderkind of academia. The funny thing is they always place the proof of their grant-sucking theories far enough ahead in time that they will never be held accountable for the silent fizzle it makes when it dissipates into nothingness.

Five dimensions (of which the ARTICLE speaks) is beyond me!..

Five dimensions = alternate realities.

[Drammach]

"It won't work out because time is already an illusion in reality and a convenience in the mechanics formulas."

Is it really?
I have considered time to be our perception of the changing state of the universe...
Energy to matter, Matter to energy, Order to Chaos, the constantly changing state of the universe we live in is seen by us (life) as "time"..

We are able to percieve the 3 "physical" dimensions of length, width, depth, ( x,y,z ) and would not NEED time if our position in space-time never changed.. ( It does, this is a "simplified" example, not getting into orbital mechanics and such..)
Time would not make a difference.. x,y,z remain the same, nothing is perceived as changing..

But with the state of the universe constantly changing around us, x,y,z are NOT the same..
Our position in space-time is the same, but the universe around us has changed..
Thus, x,y,z has changed "in relation" to the rest of the universe..

OK, my brain is shredding and I can't take this any farther.
Just my 2 cents..

4 dimensions of space should not require any type of movement. Movement is time. I personally cannot imagine 4 dimensions of space.

Quantum physics has both particle and wave theory which both involves movement of particles and or energy. Atoms and subatomic particles exist in the same dimensions and are in motion. Even in abolute zero atoms are still in motion and time is still a factor. If you could stop time in theroy all motion would stop including on the subatomic level. Does absolute zero with no changes in energy or particle motion mean that time has stoped? No, because you would still have a period of existance in one state of entropy or another. Two dimenional objects exist on a plane and can't move or exist in the third dimension other than the single plane portion of the third dimension they occupy. A two dimensional existance can not move up or down as in volume but can percieve all around in any direction on that plane. Likewise we can perceive only that portion of the 4 dimension we occupy. We only occupy a portion of the 4 dimension and can only precieve that segment that intersects the third dimension while all of the third dimension can be observed from the fourth. Time is the same for all dimensions. In theroy any motion or change to the third dimension that can't be explained by the rules governed by the third dimension is caused or influenced by the rules governing a higher dimension. They are discussing a theroy on how mathmaticaly to observe an action occuring in the 4th causing an afect within the third by way of changes to gravity that defy the laws of gravity as they exist within the confines of the third dimension. Levitation without magnetics or other energy or form of motion that defies the known law of gravity can be explained as being caused by action occuring within the fourth dimension.

That fifth dimension is kind of heavy.

[taxed2death]

Yes, time is indeed our "perception" and as RightWhale pointed out can be considered an illusion. Our "perception" is what gets in the way. Take that away...and there is no need to even bring time into the discussion. The universe hums along quite nicely without the silliness of linear time (yesterday, today, tomorrow). It is a human construct and nothing more.

Once again with spell check!

His molecules are more dense than the other dimensions.
