I'm really passionate when it comes to that kind of stuff This is my first vid! ^^

On older media, the copyright may expire if not renewed. Were the animations that you used PublicDomain or copyright expired?Sadly no, but I'd love to learn how to do that. I downloaded multiple animations that are not copyrighted !
Thank you for that video.
You're massively misunderstanding just how open space is. It's next to impossible, even if you fly right through the asteroid belt.Wow, thanks for that, brilliant vid. I wonder why the space probes never hit space junk like rocks big or small and whatever else is out there, then get knocked off course, maybe they are travelling aimless, whichever way they go they will find something fascinating.
It's not uncommon for many assume to everything is separating due to the expansion of spacetime. But things that are able to stick together, including by gravity, remain essentially unaffected. The expansion is best seen as separating galaxy clusters away from other galaxy clusters. The Hubble-Lemaitre Constant, which gives us the approximate linear version of the expansion rate, is in units of megaparsecs. One parsec is ~ 3.26 light years and one light year is roughly 6 trillion miles, so just 1 megaparsec is 20 million trillion miles.But, what I am given to understand is the universe is ever expanding. It states in the video, it would take 4 light years plus to travel to Alpha Centauri (Or approximately 18,000 years!) If it takes that long and the universe is expanding, surely it would take many more earth years to reach it?
Yes, physics has been called a "conversation with nature", and math is its favorite language (paraphrasing Galileo). But it's objective-based whereby, given appropriate testing, it can be trusted. Real spacecraft are not built solely on imagination, but on hard objective-based science. This is generally true of how we see spacetime, thanks to Einstein. Better theories may appear but they will likely only treat GR as a subset of the grander theory, just like Newton's work is a subset of GR and Newton's law are still valid and used by engineers everywhere.Countless reasons but manly because it was 'invented' by man for his own use and is only relative to our planet!
technically true, but isn’t it near impossible to get there without even HITTING the tiniest speck of space dust? Hitting in all caps because I would guess it would obliterate the precious space craft.Also, the traveling across a galaxy like ours that is 100,000 lyrs in diameter will take a very, very short amount of time according to the clocks on their spaceship if they are travelling very, very close to the speed of light. This is easy to calculate using SR (special relativity).
I think you are right as any dust would impact the hull at about the speed the ship travels, and at near light speed it would be a sand-blasting effect.technically true, but isn’t it near impossible to get there without even HITTING the tiniest speck of space dust?

This is the conundrum about traveling at lightspeed. If we could... we still can’t safely... correct?
...deflector shield?I think you are right as any dust would impact the hull at about the speed the ship travels, and at near light speed it would be a sand-blasting effect.
However, if the particles could be charge ahead of the ship, and a mag field applied, perhaps most of it could be pushed aside, or perhaps funneled into the ship for hydrogen fuel.
Yeah, maybe. Shields up!...deflector shield?
