Can you possibly see if you can get a picture of this diagram. I wouldn't mind taking a look at the math involved in his theory. It sounds kind of intriguing.

Basically, he believes that gravity is the result of massive objects interacting with a neutrino field. That since neutrinos repel themselves and are traveling at the speed of light, they've formed sort of channels where they ride parallel to each other in three dimensions... sort of like a grid. And since they're going the speed of light, it's analogous to an electron orbiting a nucleus - even though the electron is theoretically a point and there is 99.999% free space, its going so fast that it appears to be a solid 'fuzz', or in this case a uniform density neutrino field. When something like a planet travels through the field and the neutrinos (some, not all?) change their course, the repulsive force used to change direction is imparting an equal and opposite force on the object, which would be gravity. This isn't far off the illustration I saw in a string theory where planets were sitting in gravity 'wells', although that sort of contradicts itself.

He had a whole diagram and explanation with how it can compare exactly to the law of gravitation, which involves the inverse square of the distance between them. Totally blew my mind, but I couldn't prove it right or wrong. Any input?
I would love to see the math. I am by no means an expert but my question is how does he explain gravity in absence of neutrinos? Let's say you're light years from any source; gravity still works. And in areas of higher neutrino density it would follow that gravity would act with greater force than in areas of lower density, no?

Great questions, I'll ask him and try to get those diagrams.

Yea but even if you are light years how do we know that gravity still exists? In some ways that seems like it could be one of those unanswered science questions.

I'm sure there are more examples, but gravitational lensing due to dark matter is good evidence that gravity is present even far far away from galaxies. And to say that gravity is only present in some parts of the universe could mean that other laws of physics break down elsewhere; it's not good science.

Startup Twin Creek's equipment creates super-thin silicon solar cells to dramatically cut the cost of solar panel production.

Solar cell breakthrough. I like hearing about this stuff !
--------------------

Startup Twin Creek Technologies is attacking the cost of solar by getting more bang from a wafer of silicon.
After four years of work, the San Jose, Calif.-based company today is coming out of stealth and introducing its product, a machine designed to slash the cost of solar cell manufacturing. The company claims its Hyperion system cuts the cost of making a solar cell in half and brings total production cost from about 85 cents a watt today to around 50 cents.

Hyperion is now being evaluated by leading solar manufacturers and the company expects to have a number of them operating by next year, according to CEO Siva Sivaram. The machine also allows solar makers to make flexible silicon cells.

In an effort to lower material costs, solar manufacturers over the years have been able to use thinner wafers. Square wafers are sawed off from ingots of very pure silicon. During production, wafers are treated and turned into solar cells. Then cells are assembled into a solar panel.

But getting beyond 200-micron thickness has problems because wafers get brittle, which limits the costs which can be saved on materials, Sivaram said. The Hyperion system uses a technique called proton induced exfoliation to create slices as thin as 20 microns from existing wafers. "It's like a ream of paper and you're taking sheets off of it," Sivaram said.

The machine blasts hydrogen ions, or protons, at silicon wafers. The protons embed themselves as a layer of bubbles. Then, the machine heats up the wafer to expand the bubbles to break off a sheet from the wafer.

This effect of hydrogen ions implanting themselves has been observed for decades, but using it for solar cell production required totally different engineering with high energy and high doses, Sivaram said. The thinner cells are as efficient as thicker ones and are flexible so they could be used for solar awnings or other building-integrated photovoltaics.

The company itself is stacked with an experienced group of executives and engineers, including co-founder and chief scientist Chris Petti. It has raised $93 million from Crosslink Capital, Benchmark Capital, Artis, DAG Ventures, and a Taiwanese funding, according to a representative.

Twin Creek Technologies has also received $30 million in loans from the state of Mississippi, where it has a demonstration plant. There solar manufacturers can come and test their specific production processes with Hyperion, Sivaram said.
If the company does sign on manufacturers to use its equipment, it could result in a significant cost reduction for solar power consumers. Sivaram estimates that getting to 50 cents a watt production costs would bring the industry to about $1 per watt installed, a price that could make solar cheaper than grid power in many places.

The effect on market prices, even if the product is purchased by many manufacturers, would take time, however. Hyperion can produce cells at a rate of six megawatts per year, which is a small fraction of the solar industry's production.
Still, Hyperion and the work of other potentially disruptive silicon cell manufacturing technologies, such as one developed by startup 1366 Technologies, point to possible breakthroughs which could benefit consumers and the industry. Right now, cutthroat price competition has led to several bankruptcies and few solar manufacturers actually making money, say analysts.
Even though Twin Creek has seen interest from solar manufacturers, Sivaram said his biggest concern is that solar manufacturers will be reluctant to adopt Twin Creek's new equipment, which costs millions of dollars. "There's no other way for the solar industry to proceed without getting more value from the materials they use," said Sivaram.

I've been toying with idea for a few days; let me know what you think (Mash, maybe you know something I don't that would kill this idea..?):

  1. The universe is expanding
  2. As it expands, the volume of physical space "inside" the universe is increasing
  3. Vacuum energy is all but proven
  4. As physical space expands, so does the total vacuum energy, but energy cannot be created...

Neutrinos shot through 780 feet of stone, spell out their name
Quote:
A group of researchers communicated a message through 780 feet of solid stone using a beam of neutrinos, the University of Rochester announced Wednesday. When the message came out the other side, the scientists were able to read it perfectly: it said, perhaps unimaginatively, "Neutrino."

Neutrinos are nearly massless and travel very close to the speed of light. Because they only interact with matter via gravity and the weak force, they can pass through substances, including entire planets, with little disruption. Scientists have talked about using the particles as a messaging alternative to cables or satellites, sending messages to the other side of the earth by going through the earth, rather than going around the long way or sending messages into space and back again.

The equipment to send neutrino messages is still wildly expensive. The researchers who sent the "Neutrino" message used a particle accelerator at Fermilab with a 2.5-mile-circumference track and the 5-ton particle detector named MINERvA. To signal the message, the scientists used binary code, with a group of neutrinos fired corresponding to a 1 and no neutrinos fired corresponding to a 0. Even MINERvA can only detect about one in 10 billion neutrinos, so the particles had to be fired in very large numbers to register.

Because the equipment is so expensive, actual communication with neutrinos is still a long way off. Still, the authors note that the particles are barely affected by gravity and not affected at all by magnetism; eventually, they could provide a stable alternative to the electromagnetic waves we use now.

Vacuum energy.
Is the the modern term for Ether?

Zero-point energy has been observed in a lab via the Casimir effect.
http://en.wikipedia.org/wiki/Zero-point_energy

And I've yet to get a solid explanation of the medium through which EM waves propagate. I asked on physics forums and it blew up to a 10+ page thread. The best explanation I've seen so far is that spacetime can only be expressed in terms of mathematics; there is no physical manifestation.

Yup. It's Ether all right.

edit: Picture showing volcanic activity on Jupiter's moon Io.
Quote:
Io remains one of the random bits of weirdness in our solar system. Since it's discovery by Galileo in 1610, it's been confusing and amazing scientists. It's larger than our own moon, is the most volcanically active object in the solar system with volcanoes that erupt liquid sulfur dioxide, and has a molten iron/iron sulfide core due to the immense tidal heating associated with orbiting so closely to Jupiter (roughly 350,000 km). The magnetosphere of Jupiter sucks off the dust and gasses eminating from Ionian eruptions at a rate of about 1 tonne per second. It has no magnetic field of its own, but instead has a magnetosphere created by Jupiter's, which induces an electrical current along the magentic lines of force from Jupiter's north pole, through Io, and back to Jupiter's south pole, which in turn creates an auroral glow similar to Earth's aurora. It's orbit is encased in a plasma torus of high-energy radiation and ionized sulfur, sodium, oxygen, and chorline. And it looks like a moldy orange.
