If you invert the flow of the electrons, a receiver becomes a transmitter.
Speakers can become bad microphones and vice versa. Pretty sure that a radio telescope is a very bad transmitter for human music, but it could be possible with some changes...
Ehh not really. That's kind of like saying if you invert the flow of photons, your eyes work as flashlights.
"It could be possible with some changes" the changes would amount to removing the receiver and replacing it with a transmitter. In this specific case I'm not sure if a transmitter already exists at this antenna and it's definitely possible one does, but that's not a guarantee at all
There is no such big differences between a light emitting (LED) and a light receiving diode (photodiode), they are just the reverse of each other. In fact photodiodes can even emit light, but very inefficiently. Same in reverse, LEDs can also detect light, just badly.
It seems like most efficient energy conversion methods can be used in both directions.
Yes, but you would blow out most of the amplification circuitry in a radio telescope reciver if you tried to use it for broadcast at any kind of power.
