Yorick @sh.itjust.works The magic of a clear line of sight and vacuum for a good ~384'300km!
So should we do low power communications by using the moon as reflector dish?

Hugin @lemmy.world There was a NSA program that listened to soviet messages by collecting the transmissions that bounced off the moon.

I gotta say, the moon’s really starting to sound like a fucking snitch.

That's what the anti-tachyon modulation circuit is for, to change the time phase and remove most of that lag. Once they're in sync, it's literally real time!

Viking_Hippie @lemmy.dbzer0.com the distance is 384400km
That's almost the distance between my bed and the kitchen before my first cup of coffee!

(People who argue this unironically are a pet peeve of mine. Yes, there are limitations on what's possible.)

I use about 800mW for my fpv drone and if you get a little bit away from yourself and go behind a tree or something you could lose video pretty easily

Wonder what the latency would be like trying to fly my 3.5" on the moon from earth
Although I suppose the lack of atmosphere would be the bigger issue...

Think of the speeds you could fly at with no drag! I'm so bummed that the Grace Hopper drone didn't get to fly after Intuitive Machines fluffed their second landing. That would have been awesome outreach from NASA.
We want drones on the moon!

My Bluetooth buds often get interference - technically 100 mW, distance from my head to a pocket.
12 0 Replymoody @lemmings.world technically 100 mW
Technically a maximum of 100 mW, but realistically much lower than that.

yesman @lemmy.world To be fair, that's an insignificant distance for light to travel.
5 0 Reply7eter @feddit.org Still takes at least 2 seconds for the round trip.
6 0 Replyyesman @lemmy.world Well, according to my ex, even 30 or 90 seconds is an interval unworthy of consideration.
