I've been thinking. (Mod edit - moved to Science)
What else could physics show? For years things were held to be true in physics, but then scrapped. Common knowledge of the time was disgarded due to superiour understanding.
It was once believed that space-time wasn't physical. It is now know that it is.
It was once beleived that protons are the basic building blocks of matter. We now know of the sub-atomic particles.
What else do you think physics will lead us. Especially with the LHC coming on line (Hopefully soon). Will the theory of everything finally come to?
No real point, just pondering

Pineapple, you want this moved to the science forum? It seems more appropriate there.
Oh, yeah. I posted in the A vs T out of force of habit LOL.
Hopefully we will get closer to a 'Theory Of Everything', Higgs Bozon understanding and closer to detecting/observing 'gravitons' or gravity 'particles'.
If they fine tune table-top accelerators, then we may be able to go to insane energies and develop a TOE.
My pondering arose when I realized when physicists found something important, they were looking for something else.
I read an article today by Neil Degrasse Tyson where he describes the early years with Hubble's flawed mirrors. He said that the scientists did not want three years to go to waste while they engineered a repair mission. A new software suite was written to help decipher the horribly blurred images we were getting back, medical researchers got a whiff of the new software and thought it might be useful in mammogram imaging. Now countless women can attribute early detection to a flaw in Hubble's mirrors. It was a very interesting article on space exploration.

Bump.
I dont know how much we want to speculate on how physics will develop, because it's often antithetical to intuition.
Doublethink means the power of holding two contradictory beliefs in one's mind simultaneously, and accepting both of them.

My guess is that they'll find some kind of barely-there particle that is actually dark matter.
People who think there is something they refer to as god don't ask enough questions.
This:
In the words of Michio Kaku 'Gravity doesn't pull, space pushes.'
That is a drawing
More of an illistration of how massive objects bend space.
Here:
See that ring? That dark matter warping space.

gravity is cause by the curvature of space
Once again, Michio Kaku: 'Gravity doesn't pull, space pushes.'
I mentioned table top accelerators, they work by pulling space-time from underneath the object, much like pulling a carpet to get the table on the carpet to move. Space moves at 10^50m/s, so it can achieve great speds at short distances hence the 'table-top' part.

Special relatvity. 'The speed of light is constant in all frames of reference.' This shows that light is tied in with space. For example, if you were flying in a space ship at 99% speed of light and shot a laser beam outside the window, you would measure the beam to be 3x10^8m/s. If I was watching you and staying still I would also meaure that light to be 3x10^8m/s. So c(The speed of light) is tied in to space.
▲t=t/SQRT(1-v^2/c^2)
This is the formula for time dilation (Which has been experimentally verified). So space can warp light around a massive object. (Since they are linked)
If Space curves, light curves as shown on the picture I posted previously.
See above. I could also go into intial expansion theory (The space travelling at 10^50m/s part), but my proof above is enough.
If you don't understand something, ask. I am studying physics.
Oh, and space-time material is also dectable via gravity waves. In an event such as a super-nova, the space-time fabric will warp and ripple, much like taking a bowling ball off a mattress, the matress will return to it's original (level) state and hence send a ripple since the bowling ball compressed the matress.
We can launch a satalite system of lasers to detect the force of these gravity waves.

Forgive my ignorance, but what is "the LHC"?
Did a quick google. Google is your friend.
Large Hadron Collider.

It is a particle accelator capable of high energies, and hence is the best bet to detect the Higgs Boson (Since it's so heavy). However, this requires a massive amount of space, so the table top accelerators could be more practicle, since they require only limited amount of space, since they move space from underneath the object, and can get it up to speeds faster.
Very cool. I wish I could say I knew how cool, but my knowledge of physics is very limited...D'OH! Whenever a conversation about physics (or something else outside my areas of study) is launched I wish I had unlimited time and unlimited brain power to learn, learn, learn as much as I possibly can.
There is too much knowledge, too much that is unknown and far too little time.

What causes space to curve?

Did I not just post pictures showing how matter curves space?
The answer is matter. Read my post about gravitational waves and the link about L.I.S.A. While you're at it read about gravitational waves.
http://en.wikipedia.org/wiki/Gravitational_waves
In Einstein's theory of general relativity, the force of gravity is due to curvature of spacetime. This curvature is caused by the presence of massive objects. Roughly speaking, the more massive the object is, the greater the curvature it causes, and hence the more intense the gravity. As massive objects move around in spacetime, the curvature will change. If the objects move around in the right way, ripples in spacetime can spread outward like ripples on the surface of a pond. These ripples are gravitational waves.
No. Everything is either physical or a measure of something physical (temperature is a measure of energy etc...)

Because the more massive the object, the more it warps space, so the more pushing it does.

By studing physics and reading 'The God Theory'
That's what Newton first thought since he didn't have the resources to know that it's space.
Photons have zero mass, Newton's formula was F=GMm/r^2. It is now shown that photons shift when entering a gravitational field.
With gravitational waves/lensing it has come to the conclusion that it is space-time.

If you would be so good as to excuse my ignorance, my education is in the Humanities and Law. I have recently read A Brief History of Time and The Elegant Universe. AiiA, I just want to be certain that we aren't eschewing the material I just read, right?
I will be seriously pissed if I spent all this time working on these concepts and they've changed already. My father is one of the top Chaoticians in the country, and I've given up trying to follow his thoughts. Is physics out the door, too?

Did you read my topic? I show why I think it's possible.
As for Haisch being 'infected', he went into priest training, but I don't think he's Christian. He gave it up to study astrophysics.
I don't think so. Newton came up with the inverse square law (The 1/r^2 part), but perhaps Cavendish derived the actual formula.
No, space only pushes when an massive object is warping it.

To best illustrate this take a soft matress and place two bowling balls side by side and maybe you may be able to see it.
That said, it is slightly deceptive. The 3-D bowling ball is warping a 2-D mattress. Gravity is caused by warps in 3-D
Good question. As Hawkins says 'Space is finite but boundless'
There are some theories, but I don't know.
