After clarifying distances and speed with ChatGPT (it understood 1% as 100% initially):
"Apologies for the confusion. Let's recalculate the time it would take to reach Alpha Centauri with a speed of 1% of the speed of light.
Using the same distance of approximately 4.13 × 10^13 kilometers to Alpha Centauri, and a velocity of 1% of the speed of light:
Velocity = 1% * 299,792 km/s
Velocity = 0.01 * 299,792 km/s
Velocity = 2,997.92 km/s
Now we can calculate the time it would take to travel this distance:
Time = Distance / Velocity
Time = (4.13 × 10^13 km) / (2,997.92 km/s)
Time 1.376 × 10^10 seconds
Converting this time into years:
Time (1.376 × 10^10 seconds) / (3.15 × 10^7 seconds per year)
Time 436.5 years
Therefore, if you were to travel at 1% of the speed of light, it would take approximately 436.5 years to reach Alpha Centauri from our solar system.
Please note that this calculation assumes a constant velocity and does not account for time dilation effects or the technological challenges associated with reaching such high speeds."
So, around 400 years to send the probes, but only 4.3 years to get the data back.
