Hello I am new here and my question is this:
Spatially, what is the distance EM travels through space before redshift alters the wave to the extent that a radio signal becomes a microwave signal?
Also when a radio signal containing information redshifts to the microwave band is the information retrievable still? Such as audio?
These questions are based off the movie contact.
is it correct that we cannot as yet, boost a signal, we can merely relay or jump a signal?
And finally what makes a signal strong as opposed to weak? The shorter a wavelength the higher the energy. This I understand but I do not understand when ones says we have a powerful broadcasting antennae.
If one has a receiver, why would one say the signal is faint when there isn't enough distance in order for redshifts effects to be pronounced
once these questions are answered I eventually want to determine whether there is A shell threshold distance aroundearth such that we can determine a distance of nem front which can rule out any other EM front conflicting with ours in the local region. What would happen when the noise front of ones planets radio and video signals clashes with another?
In the movie contact the star Vega received our signal which was 65 light years away or approximately but the signal wasn't redshifted did the movie assume that they were able toreconstruct the signal using technology or was there not enough distance involved in order for the signal to be red shifted??
Thank you
