Every time you hear about our television and radio is filtered in space …?
people hear the extent of the planets will be able to tune the old clock, depending on how many light years away from home. However, if they are so far not the "noise" control the sun all radio signals from Earth will happen to be pointing an antenna in that direction? I work for a cable company, and twice a year, about of the equinoxes, the signal is lost in each of our channels for about 10 minutes or more (not less exactly the same for each channel, it is rare to be reported with many people), while the signal path of the satellite dishes to take is in direct line with the sun. This is because the interference sun. It would be exactly what happens at a greater distance? It could also be a reason why SETI has not found evidence of extraterrestrial intelligence to date?
Correct! noise interferes with the sun. However, there are ways to dig a signal even when the noise is (slightly) stronger than the signal. However, even if deliberately signals are sent in the gaps in the noise spectrum of the sun, there would be a distance beyond which the signal can be recovered in general "noise" the rest of the universe. SETI is, of course, very limited because of it. However, we hope that somewhere, a civilization might send a strong signal wavelength where the overall noise of the universe is minimal. This bandwidth, less noise, is called the "pond" as it is between the natural wavelength emitted by hydrogen H (21 cm – around 1420 MHz) and hydroxyl OH (18 cm – about 1,666 MHz) The first efforts of SETI (When there were fewer resources and tools) has focused on this space. We are now extending to other wavelengths as Multi-channel analyzers to be more efficient. We humans =.
