Nothing since a radio telescope isn't a fucking speaker.

AM doesn't reach further than FM, it's just that historically we've been using AM at lower frequencies, and these travel further. You could transmit with FM just as well on these frequencies, and get the same range.

These radio telescopes don't transmit anything at all, they listen to radio waves coming from the cosmos. Much like a normal telescope doesn't transmit light.

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.

An LED (or photodiode used as one) is a fairly simplistic device compared to an assembled receiver / transmitter. Just like you can burn gasoline in a car but you can't push a car to turn the engine to make gasoline - it's a complex system that really only works one way.

Nothing gets burned or otherwise destroyed when receiving EM radiation via a dish and converted it into electricity via a receiver.

Sure, the amplification stage of the process likely works only one way, and should be replaced in order to send something.

The one way process of burning oil to generate heat seems much more primitive than the energy conversion offered by a diode, TBH.

You can push or tow an electric car and charge their batteries. Because electric motors are also generators.

Even with your simplistic fossil fuel car in your example the alternator within can also be used as a motor.

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.

I'm actually surprised you got so many up votes for that level of technical correctness. This is a tough room

Pathetic, everyone knows that the BF3 intro will shake any rust off any car near by.

At first it goes like synth and then it is dudududu dudududu dudududu dudududu dudududu dududuuddududuuud shiuush dududududududuuuuddudddududududddududdudududduududududu

That's true, but you shouldn't forget that there is a large part of it that goes dudududuuuu dudududududuuuuu dudududududuuu dudududududuuuu

The 1989 Belgian techno anthem Pump Up the Jam.

Pump Up the Jam is an anagram of 'Jump Up the Pump'.

This song was played five times in a row at the funeral of director Stanley Kubrick.

Techtronic's home planet, Earth, consists of 70% water.

If you isolate the individual drumbeats from this song and arrange them in a circle, it unlocks a cheat mode that allows you to pass through solid surfaces at will.

Let’s be real, anything by The Prodigy on a speaker that size would fucking slay

Bigass subwoofer, blast Smack My Bitch Up, feel your soul exit your body.

God. Damnit. I just managed to be able to listen to Gorillaz without just randomly singing ram ranch. Now it's back on my mind

Supernaut

A cover of Black Sabbath's "Supernaut", by Al Jourgensen of Ministry's side-project 1000 Homo DJs with vocals by Nine Inch Nails vocalist Trent Reznor.

Ready to die by Andrew W.K. The song ending with “You just heard earth music. This was a warning.”

I was thinking Sabotage. Turn that scene from Star Trek Beyond into a reality.

Goldeneye Surface level PTSD. Enemies beyond your sight horizon due to fog/snow, no map overlay for relative positioning, memorization was the only way to not get lost.

That sniper rifle was so dope, but the accuracy of CPU players with an AK like across the map and then /gaspingsoundwhenhit was so frustrating lol

If you haven’t, give nick mason’s saucerfull of secrets a spin.

Their version of controls for the hearth that i heard live was absolutely transcendental.

Ok ignoring the fact that this isn't a speaker, if it was and the question is what would I play on a speaker this size, then probably this.

Y'all are way too nice. I'm pumping a 60Hz square wave right into that thing at max volume.

Thanks for the wiki link, OP. You sent me down a pleasing rabbit hole reading about the large radiotelescopes built by the USSR.

And also, completely tangentially, I have nostalgia for playing the very first Destiny game because the environments were designed with those early USSR Deep Space program aesthetics.

He's bouncing off my booty cheeks I love the way he rides. I can hardly breathe when he's pumping deep inside.

It would be funny to broadcast corny 80s dance music to aliens, ngl. Hopefully they don't have that Mars Attack physiology that makes their heads explode to jams.

Id freak out about having to make a choice and then just blurt out souvlaki space station because it seems like a safe bet of sm i like at high volumes.

"Obet the groove" for theme reasons but for personal choice "heart of a dancer"
