New Theory of Gravity Decouples Space & Time
eldavojohn writes "Petr Horava, a physicist at the University of California in Berkeley, has a new theory about gravity and spacetime. At high energies, it actually snips any ties between space and time, yet at low energies devolves to equivalence with the theory of General Relativity, which binds them together. The theory is gaining popularity with physicists because it fits some observations better than Einstein's or Newton's solutions. It better predicts the movement of the planets (in an idealized case) and has a potential to create the illusion of dark matter. Another physicist calculated that under Horava Gravity, our universe would experience not a Big Bang but a Big Bounce — and the new theory reproduces the ripples from such an event in a way that matches measurements of the cosmic microwave background."
You mean the space-time continuum doesn't exist? Star Trek is wrong?

Does this theory suck or is there some pull to it? It just seems so weighty to me.

I believe they will all be right, but it will only be from the perspective of the observer/believer which is right at the moment. However when it isn't being observed it will be both right and wrong until observed again. Therefore there are multiple pinnacles and it won't matter which are right or highest. Just have your towel ready because on top of the pinnacle is a little man who is only going to apologize for the inconvenience.
Always have a towell ready.

It's a PDF version of a PowerPoint deck, so it's not exactly easy to read.
Indeed, informative link but I think your signature should be at the start of your post. I was doing pretty good right up until they plugged the ansatz into the Horava’s action to produce the reduced Lagrangian.
My work here is dung.
To differentiate myself from the lot of you bores I shall take a first name: Fah. From this point on I am Fah Q! :)

... until they plugged the ansatz into the Horava’s action to produce the reduced Lagrangian.
Huh. I didn't get that far. And I'm pretty sure that whatever it that is, it's illegal in Texas.
1. Gravity is still spooky action at a distance with no causal mechanism defined.
2. I don't think time, as in "time lines" or some kind of unidirectional movement through a medium exists. Now exists, hypostatized out of a past (which stops existing when it stops being now) and which in turn hypostatizes the future (which does not exist.)
3. Electromagnetism is the dominant force in the heavens as it is on Earth.
4. Stars are organisms and they reproduce through fission.
5. Galaxies are powered by vast electric circuits; beads on a string.
When a true genius appears, you can know him by this sign: that all the dunces are in a confederacy against him.
You fixed it by misspelling General Relativity?
Or maybe you actually meant the theory would be better than 'Reletivity'. That could work.

Your cited experiment seems to show entanglement by observation is FTL.
But really, what's faster than a two-year old? Therein is the true upper-end limit of c.

In my home reality, we had machines to jump into parallel dimensions, but baguettes were outlawed when Palin took the U.S. presidency and invaded France.
I hadn't heard of the croaking bird dimension though. I'll have to visit.

In one day, and they are both in California. I am stuck here in New Jersey. New Jersey is Hell. When people die, they don't go under the ground, they just pop up somewhere in Newark. See, us citizens of New Jersey are immortal because if we are killed, we just pop up back again in New Jersey. Its just really hard to navigate around Newark, so that's why you don't see us again..................
i am so very tired....
I have to assume he did not - lacking clarification on the matter I'm left to assume that the conditions were not something simple he could test no a whim.
Wow. Anyone else see that? From my location, the n arrived before the o; however, the parent clearly typed them in order (o before n) in our reference frame, so I think we've just witnessed information traveling faster than light! Woohoo!
My hypothesis about gravity:
Everything is growing. We can't see anything growing, because our rulers and tapemesures and everything is growing. That's gravity: Just the growing earth pushing against your growing feet. Gravity at a distance is just objects growing towards each others (the void doesn't grow). Come to think of it. It's probably a bad hypothesis. It couldn't explain a slingshot effect, could it? Nevermind.
Some of my favourite people are from th US; Vonnegut, Chomsky, Bill Hicks.
But does it also predict that time is an illusion, lunch-time doubly so? If not then there is still room for a more refined theory.
Then I shall be Fah Q 2!

It's strange to me that Dvali would abandon his model for allowing FTL propagation of information unless he experimentally checked the conditions in question to see if information really could propagate FTL in those cases.
Sorry, my bad. I have to be the one who checks for FTL propagation, union rules. I'll get to it after I finish my "get laid" project. I'm particularly hopeful. Just the other day, I made eye contact for 1.3 seconds with what I assume to be the female of our species. I think I can get that up to 10 seconds without breaking any laws of the legal kind. It's very promising progress here.
Well Fah Q both then
Cousin to Sofa King Awesome, I suppose. You people are so immature.

Just curious, do you own a horse?...

You have to be careful thought. Two-year-olds also have powerful destructive potential, especially when coupled with auxiliary particles like the PB&J particle, the Red Kool-Aid Particle, the Chocolate Candy Bar particle, or (worst of all) the Soiled Diaper Particle. The only safe way to interact with a two-year-old is to buffer all of your observations through a Mommy Interface, especially when the diaper appears to be in danger of going super-critical. On the other hand, the Mommy Interface also has a major drawback. Without fail, all of your data points come back as "adorable."

Same as with the Highlander. But I digress.
Not that this wasn't entirely predictable.
No one is questioning the intelligence of the soviets or eastern europeans. The problem was that when they did science, they did it in an inverted way. For example, in Soviet Russia, the particles accelerated you.
The Jatravartid People of Viltvodle Six firmly believe that the entire universe was sneezed out of the nose of a being called The Great Green Arkleseizure. They live in perpetual fear of the time they call The Coming Of The Great White Handkerchief.
Fah Q and the horse you rode in on?
Nah, don't worry. In a few years it'll all be glommed together again as space-time-matter-energy with one spiffy equation to rule them all.
... and in the dark matter bind them.
The Tao of math: The numbers you can count are not the real numbers.
There are actually only to possibilities. Either the things continue to work the same way they did before, or they don't. If they do, then acting on the assumption that they do is clearly the right choice. If they don't, then we have no idea what to do; whatever we do could be right or wrong. Therefore the rational behaviour is to assume that the rules continue to work.
