Just a question: If our spacecraft travel at that speed and are going towards another star system, suppose they are right on target even. Wouldn't that be considered an act of war to any possible intelligent inhabitants, unless the spacecraft can sense the obstruction and stop in time to avoid collision? Are we really that sure that we are the only life in the universe?
Nobody said we are the only life in the universe. A truly intelligent civilization would recognize it has no weapons. And the chances of it hitting anything are soo negligible and of determining who sent it is zero.

Joining fresh here and responding late but with a potential update that Sora project might be the opportunity for creating such sophisticated videos now. Read the tech. specs here: https://openai.com/research/video-generation-models-as-world-simulators
Np though it looks like you are partially right, as the speed without the influence of the planets, the winner would still be Helios 1 and 2.

Keep up the good work (keep making and improving on your videos).

I meant to ask, did you do any of the video physics animations yourself, or you just kind of pieced it together from other sources?

Yeah, maybe. :) Shields up!

It's not something I've read about or even thought about, but 99% of the material encountered between here and another star will be gas, mostly hydrogen. I'm just guessing a laser package could ionize it, and probably the dust, giving it enough charge long enough to have a powerful mag field kick it to the side. I could be wrong.

But the amount of debris (mainly gas) isn't all that much, I don't think.

The Local Bubble ISM density is only about 0.05 atoms/cubic cm. So if we have, say, a 50 meter diameter hull, then it would encounter only about 7 grams during the travel to Alpha Centauri. When we add for 1% dust, and we double those hydrogen atoms since most is likely molecular hydrogen, then we still will likely be under 20 grams.

This would even be a small percentage of the no. of molecules the hull would see for a depth of only 1 cm when it was built at sea level.

Still, near the speed of light, the smallest particles can pack quite a punch.

I recall the report some years ago of a measured cosmic ray (proton) [at very close to c] that hit our atmosphere with an equivalent energy level of a Nolan Ryan fast ball. :)
