Well, I guess you can argue Flash can't acclerate to 99% of light speed in the space of a femtosecond based on the scan.
But I don't think it can be used to argue Flash is sub-lightspeed due to the reason I said above. Since Cyborg should be talking about the acceleration, not the speed it hits the target
Originally posted by qwertyuiop1998I get that you want the missiles to be super-C so that Flash’s comment can’t be used against him but it’s a lot more credible to just chalk it up to a PIS statement from Flash. Cyborg says the missiles instantly accelerated to 99% c. Maybe they kept accelerating past that but that’s nowhere in the scan, so it’s just a theory.
Hmm, I don't think Cyborg means its moving sub-lightspeed at the time it hits the target. Because light can only travel 300 nanometers in a femtosecondSource: https://news.mit.edu/2012/explained-femtoseconds-and-attoseconds
So it is more likely Cyborg was talking about it's acceleration, not the speed its moving at that time
And Flash’s comment was about speed, not rate of acceleration, so… it’s just dumb writing. Throw a hero under the bus with a moment of idiocy so the reader goes “wow!”
Well, I just think the scan doesn't necessarily mean Flash is sub-lightspeed or something( and femtosecond is a time unit, not a speed rate). Because like you said, Flash was talking about it's speed, however, Cyborg was talking about it's acceleration
Basically what I said in this post

That's because you're clever... you're wrong though
Originally posted by qwertyuiop1998I mean if we agree that Flash was talking about speed… the rest is moot right?

I assume we also agree that Flash was wrong. So the scan doesn’t mean that Flash is sub-light or faster because his comment is meaningless.
If we assumed a constant coordinate acceleration (= the acceleration measured by an external observer such as Cyborg), the acceleration of the drone would be: a = 3.0×10^23 m/s^2.
However, a more natural assumption here is that the drone engines produce a constant proper acceleration (= the acceleration felt on-board the drone), which in this case turns out to be:
a₀ = 2.1×10^24 m/s^2.
If the (rest) mass of the drone is approximately 1 kg (and its fuel is massless), the drone engines must be able to generate an accelerating force equal to the standard weight of 3 Moons. Or 30 Moons, if the drone mass is 10 kg instead. Not bad. And this assumes no drag due to air. So, this calculation still downplays the drone's feat by a lot.

At least, in the scan, Cyborg only talked about acceleration of the drones, not it's speed. Does it accelerate beyond 99% lightspeed? never mentioned, but on the other hand, it also didn't mention it stops accelerating after the femtosecond it reached 99% lightspeed, you also need to add something to make the drones' speed capped at 99% lightspeed
In a nutshell, It is like saying "Object A accelerated to 99 percent of the speed of sound in 0.0000000001 second, it is faster than object B". the only thing we can be certain is object A's speed is at least 99 percent of the speed of sound, however, it doesn't necessarily mean object B's speed is slower than 99% the speed of sound
Or just look at Magnon's calculation when he replaced the time unit to seconds instead of femtoseconds to see what I mean
