I dunno if its me

The answer is yes, the lights are getting brighter. With the new xenon, LED, and ultra-blue lights they are all brighter than standard headlights from years gone by. All in the goal to make it so the drivers can see more-- which they do-- while at the same time, they blind everyone else.

How to explain this grammar question...

Because if it was cut by large pieces... it implies the pieces are doing the cutting.

Time dilation is a lie.

So, I found my math...

Earth to Proxima Centauri = 4.22 Light Years away
Constant-Thrust Trajectory (maneuver)
4.22 Light Years = 5 years @ 0.95m/s^2 = 0.5C
= 10 years travel time

So the theory is that the ship accelerated up to 0.5C stayed there for 5 years, then started the deceleration process.


t^1 = dilated time
t = stationary time
V = velocity
C = speed of light


=10yr โˆš(1-(0.42C^2)/C^2)
=10yr โˆš(1-(0.1764))
=10yr โˆš(0.8236)
=10yr * 0.9075
=9.075yr on the ship

Time dilation is a lie.

If I understand time dilation properly, it is how things are effected by time/speed.

Yes, light leaves the star 1 million years away, and travels for 1 million years to reach here. (it is already travelling at light speed)

When an object increases speed to near-light speed, things change relative to its origin. The outside world seems to slow down due to the change in speed.
The trip for the object takes 1 million years from the point of view of the origin, but it takes less time from the perspective of the object.

For a novel I started, where a colony ship was going to Proxima B, I figured out the math... The trip from the perspective of Earth was going to take 10 years. On the ship it would take right around 9.
(I'll see if I can still find my notes for that story)

Now all of that said... part of the FTL drives, depending on the theory, is that the warp field/hyperspace/etc. is that it allows traversing vast distances without relativity affecting those inside the bubble.
