Microwave background radiation, which can tell us about the moments that created the universe, there is an aspect rarely investigated, and if we can expect the device is sufficiently accurate to reveal new information about the early universe. This aspect is the range of frequencies, the spectrum of the radiation
Many cosmologists talk about the microwave radiation - Micro, their snapshot of the universe at the tender age of 400,000 years, seemed to have already met the subject mobba as much as possible. After all, the "Planck", mobba the new satellite of the European Space Agency, is in fact extract "all available information" spatial patterns of fluorescence. However, cosmologists think the stage after radiation Planck say that hardly researched aspect, if we view it is sufficiently accurate instrument mobba will reveal new details about the early universe.
This aspect is the range of frequencies, the spectrum of the radiation. Astronomers routinely use the rainbow of colors emitted by the sun and other stars to determine their composition. Meeting of the American Astronomical Society, held in January 2009, said astrophysicist Rashid Sunyaev-known Max Planck mobba Institute for Astrophysics in Grcing Germany, the successor of the satellite "Planck" may collect fingerprints similar to the background mobba radiation, the spectrum seems, right now, and generic.
Pachinko game until it cooled enough for protons to electrons and form hydrogen atoms - a process called recombination. Since electrically neutral atoms are less likely to scatter photons. Thus photons began to stream across space in straight lines more or less. Pachinko had thoroughly mashed their spectrum, the only thing cosmologists can glean from it is the overall density of the material.
However, this picture glosses over two thin. First, you need some time to protons were able to bind strongly to electrons. Initially, the grip was loose. Sealed newly created was to lose energy by emitting mobba photons, to stand, and he did it in his spare time.
To complicate the picture further, a photon from one atom tended to take an electron from another. Like crabs in a bucket, the atoms tripped each other. Their mutual antagonism was cosmic expansion, deplete the energy of the photons and slowly tilted the scales in favor of the formation of atoms, not destroying them. Time frame commonly cited 400,000 years is just a convenient milestone; actually took two million years to complete splicing. mobba
The second aspect is that although the universe consists mainly of hydrogen, it is also the amount of helium. Helium nuclei, which include mobba two protons, the positive charge is twice hydrogen nuclear charge, so they tie Electron stronger. Hence the helium nucleus formed earlier atoms hydrogen nuclei: the electron catching their first age about 15,000 years and the second electron age 100,000 years. Moreover, mobba they were able to evade the crab bucket syndrome.
Photons mobba emitted by hydrogen and helium added some primordial soup fingerprint indicating composition. Measuring the number of photons emitted by the helium will determine exactly how much helium the universe - the size that now must be extrapolated, with no simple amount of helium in stars. "This is an absolutely clear way to find the relative proportion of primordial helium," says Sunyaev. In addition, photons from helium date the era before the release of the CMB. They might bear the mark of the processes now hidden from us, such as exotic particle decays.
The problem is that each photon of helium primordial photons have billion. Fortunately, the helium atoms were formed very quickly so they emitted photons are concentrated at certain mobba frequencies, called spectral lines. Sunyaev and colleague Vince cage from the Canadian Institute for Theoretical Astrophysics pushed to initiate a new mission to scan frequencies to search mobba for records the number of photons, such as moving a finger across a surface to bump bar is too small to be able to measure. "To observe these lines will need to watch at a fixed point in space and in the frequency scan," says Jose Alberto Robinho - Martin from the Institute of Astrophysics of the Canary Islands. However, current tasks, including the Planck satellite, scanning the space fixed frequency.
In a history Hkosomologyt back. For decades seemed spatial measurements of microwave mobba radiation - a completely uniform microstructure to cosmologists have identified the spatial fluctuations. The spectral measurements now appear completely uniform. Once cosmologists see the spectral fluctuations are expecting another flood of information about the early universe.

Sbdrmis Judah: As I mentioned before this idea lets give everyone a place to express themselves. It does not cancel what exists but it certainly gives space structure of the universe behaves differently at different scales. You yourself preaches against excesses to follow through with ideas. mobba Find a middle ground seems possible to me more fruitful dialogue and debate of the deaf. The problem with all scientific theories mobba start it.
