The Bible has the answer to EVERYTHING and actually proves science, I have no idea why science tries so hard to disprove God?

There has to be some other force that holds protons and neutrons together.
The only logical explanation is the hand of the Lord holds all things together!

He [Jesus] is before all things, and in him all things hold together.



Structure of an atom with neutrons and protens in the nucleus and electrons in orbits

 The neutrons are electrically neutral, and so the electric force won't hold them in. Furthermore, the protons are all positively charged, and so they all repel each other. So if the electric force was the only force involved, you couldn't create a nucleus. You could try to push all those protons and neutrons together, but as soon as you let go, the protons would all shoot away from each other, and the neutrons would drift apart as well. There has to be some other force that holds protons and neutrons together.

Of course, since the electric force is constantly trying to drive the protons apart, the force that holds them all in must be stronger than the electric force. And keep in mind, the electric force gets stronger as charged particles get closer together, and the protons in a nucleus are very close together. As a result, the force that holds protons and neutrons together must be very strong. Well, in a brilliant stroke of imagination, physicists have named this force "the strong force."

The strong force is a force which attracts protons to protons, neutrons to neutrons, and protons and neutrons to each other. The force has a very short range, and this is the reason the nucleus of an atom turns out to be so small. In addition, the strong force is also responsible for binding the quarks and gluons into protons and neutrons.

NASA starts building faster-than-light warp engine

End Of Days News

Still from Star Trek TV series

Researchers at NASA’s Texas-based Johnson Space Center are trying to prove that it is possible to travel faster than the speed of light, and hope to one day build an engine that resembles the fictional Starship Enterprise.
NASA physicist and engineer Dr. Harold G. White, 43, believes it is possible to bend the rules of time and space that Albert Einstein constructed when he postulated that it is impossible to exceed the speed of light.
White's research is based on the theories of Mexican physicist Miguel Alcubierre, who in 1994 theorized that exceeding Einstein’s galactic speed limit was possible if scientists discovered a way to harness the expansion and contraction of space. And Harold and his team are trying to do just that.

‘Zombie cell’ mates biology and chemistry at nano-scale

End Of Days News

US researchers developed a process that coats a living cell with silica ‘armor’, creating a near-identical inorganic duplicate. This ‘zombie cell’ technique has the potential for building complex nano-scale machines using life as blueprint.
The process developed at the University of New Mexico is relatively simple. The team suspended living mammalian cells in a petri dish and added mild solution of silicic acid. One of the acid’s byproducts softens the protective lipid casing of the cell and makes it porous enough for the silica to flow in.

The acid then, in a process ‘still partially obscure’,embalms every organelle in the cell from the micro- and down to nanometer scale, covering them with a sort of silica armor. The resulting cell/silica composite can be then heated to either evaporate the protein ‘mold’ and created a near-perfect silica replica of the cellular structure.

Its most immediate use is long-lasting preservation of biological samples. But potentially the technique can be used to fabricate complex useful nanomachinery, says Bryan Kaehr a materials scientist at UNM’s Sandia National Laboratories.

“It’s very challenging for researchers to build structures at the nanometer scale,” he said. “We can make particles and wires, but 3-D arbitrary structures haven’t been achieved yet. With this technique, we don’t need to build those structures — nature does it for us. We only need to find cells that possess the machinery we want and copy it using our technique. And, using chemistry or surface patterning, we can program a group of cells to form whatever shape seems desirable.”

The alternative is to heat the composite without oxygen and turn the protein into porous conductive graphitic carbon supported by the silica coating. The silica can then be dissolved living a carbon structure that can find its use in fuel cells, decontamination and sensor technology.

If the composite isn’t heated, there are possible applications too. For instance, biological catalysts – the enzymes – must retain a certain shape to trigger chemical reactions. The silica coating preserves the structure at temperatures undreamed of by nature while still able to carry out reactions.

“Our zombie cells bridge chemistry and biology to create forms that not only near-perfectly resemble their past selves but can do future work,” Kaehr says.

The team reported their finds in the Proceedings of the National Academy of Sciences (PNAS).
