To scale: NOT. That dot is WAY bigger than a actual photon would be.
photons dont have a size limit. when 2 small photons merge then they becomes 1 big photon.
photons are not standard units of measurement.
That was one big photon.

We actually don't know the one-way speed of light, we've only ever measured it two-way. So it could be that in one direction, light has a preferential speed, even up to infinity and we wouldn't know.
The speed of light is a secondary constant, not a primary constant. One-way light speed has been measured and for the first time, derived from the primary constants here:
Simulation is not empirical evidence.
Light speed has only ever been measured bidirectionally.
"...not empirical evidence": oops, there goes almost half of cosmology research (including big bang).
Look up the words "empirical" and "evidence" and come back when you are ready.
It's immaterial.
You aren't wrong, but that is because they don't know how to science.
When they say "measure" they mean "laser" and that isn't the only speed of light measure. How fast do EM waves travel? "Data" can be measured several ways, and in unidirectional travel.
Conditions: set a clock on a spacecraft/rover send spacecraft/rover to distant place calculate time shift due to travel - it will be either known or constant now there are 2 clocks a distance apart. program the spacecraft/rover to receive a time signal and return the clock value when received and the difference in the times. program the spacecraft/rover to send a time signal at a scheduled time. this could be done right now with the rover(s) on mars.
test: send the current earth time to the spacecraft/rover on the hour, like 12:00 data travels at speed of light to spacecraft/rover. time received is marked and then subtracted. this value is sent back to earth. at a designated time the spacecraft sends local time back to earth, this time is received and the difference calculated.
Mars would be a good test platform because a) it is far enough away that relativity time shifts would be essentially insignificant compared to the speed of light travel time. b) the distance varies in the known orbit, giving data from relatively close to very far away, c) it allows for omnidirectional testing of the speed of light over the course of a couple years, providing a full picture of the speed of light in all planar directions.
Now you get why moon landings commutation was fake as shit. Radio transmissions and light travel almost same.
Also radio transmissions rely on air to travel. From what I understand the air is pretty thin up there
Radio waves don’t require air, they can travel in vacuums.
If they're coming off a pulsar maybe. I should have been more specific.
You're thinking of sound waves. Different ballgame.
So then being a type of radiation, wouldn't it get scattered in the Van Allen belt?
seems kinda slow
If they added a real-time dot representing a modern space craft heading to the moon, it would not seem slow.
Not trying to brag, but I've been past Neptune
Did you make it to Urectum?
"Currently physically measurable Speed of Light under these specific conditions" would be more accurate. Currently, the actual speed of light is not known. If it is, the PTB are not sharing it with the rest of us. The definition we are currently using for the speed of light is both circular in reasoning (Distance is Defined using the Speed of Light, The Speed of Light is Defined using Distance) and defined as being measured in an impossible condition (Complete Vacuum).
Distance was not defined relative to the speed of light, until c was precisely known. Before that, it was defined relative to a bar in France.
C is not precisely known. It has been measured in some specific conditions with imperfect methods, and the currently accepted speed is a prediction of how it would perform in a total vacuum based upon these imperfect measurements.
It is incredibly precisely known, and has been measured by an enormous variety of techniques, and many different conditions.
Poal, please tell me how 'c' is a Jewish conspiracy to defraud the whiteman by inflating the petro dollar or something. I'm ready to learn how lightspeed is infinite, and was also faster in the past - thus proving THUNDERBOLTS PROJECT, as God intended.
wow, that's lightning fast!
I see what you did there.
Speed of light, the religion of heliocentrism etc are all to keep the goy distracted
It's true. I was thinking about heliocentrism the last time I walked into a shut door.
takes like 10 minutes for light from the sun to reach past pluto, right?
