You could theoretically open a teeny tiny wormhole big enough to squirt a photon at a time through, but you would need exotic matter to hold it open. Maybe with meta materials some how emulating negative energy...
No idea how much power you would need though and you may need two of them one for sending and one for receiving.
That is one idea how to build a realtime ftl communications setup...
I agree, and understand the dynamics of high altitude flight, but it’s not the same as a vacuum.
Ignore the conspiracy monikers on this channel, as these experiments, like the actual science taught to our fathers, grandfathers and great-grandfathers, prove the point.
Thrust not possible in a vacuum:

Combustion not possible in a vacuum:

Light from distant stars is delayed but appears live to viewers on earth since the signal is unbroken. Unless the ship is traveling faster than the speed of light the signal will be live.
Combustion in a vac is possible with an oxygenated fuel and burning the fuel will provide thrust opposite to the direction of the burn.
Forgot to mention Newton’s third law of thermodynamics.
Ever sit in the cheap seats at a ballgame?
real itme at the unit not so real time back home, you would be charge for real time you can bet on it
The old satellite phones that used geosynchronous satellites had a delay of a second of so.
Why does the speed of light have a limit? What’s holding things up?
(Things I wonder about while the light’s red.)
Depends od the speed od the ship and the speed of the transmission. If the transmission travels at 10,000mps then when the ship is 2,500 miles away the transmission is .25 seconds behind
“Everything you see is “in the past”.”
True that is and very few of us ever pause to consider it but we never see anything as it occurs. Even if it is only ten feet away we see what happened in the immediate past. We hear what happened much further in the past than what we see. I used to watch thunderstorms and count the time between the flash of lightning and the thunder. It can be several seconds.
The speed of light is key. Anything can be sent “live.” What matters is how far the receiver is from the source. Depending on how close you like to get to your monitor, what you’re reading right now is arriving in your eye about 2 nanoseconds after the photon leaves the screen.
As you can see from the answers already given, nothing, not one thing, that you see or hear is ‘live’.
EVERYTHING suffers a delay.
Even the vision of the people you see standing next to is delayed a tiny amount. The sound you hear when they speak is delayed even more.
MOTION. The third law of thermo came hundreds of years after Newton died.
“MOTION. The third law of thermo came hundreds of years after Newton died.”
Give me a break, I was half awake. :-)
Too much pot. Time is not a perspective there is no issue.

I think some are missing the point of the OP’s question. Will a continuous broadcast be perceived as “live” as the source travels away from Earth?
To me “live” means it’s not a playback of recorded data.
When we view a live presentation, we are seeing it as soon as it’s possible to be seen. If the presentation is on Mars and we’re on Earth, “as soon as possible” is several minutes of delay.
A radio transmission is no different than starlight, just a different frequency. The delay will be the distance between source and receiver divided by speed of light. Barnards Star is about 25 light years away. Light you see from that star was emitted in the early 90s.
