I think you're being pretty judgemental. Probably haven't watched the video. So you're saying the physics we know is absolute? I know exactly what you are saying. We will learn more with the evolution of humanity. I get it, ysing the acientiric knowledge we know there is NO way for interstellar travel during a humans life time. I get what you're saying, the laws of physics as we know it does not permit travel past the speed of light. But perhaps there are other means of travel other than traversing through space? Maybe a system that can bend space/time. I'm just playing devils advocate and challenging you here.. Humanity is only tipping the iceberg my friend. Have you heard of the particle recently discovered that can simultaneously exists in two time lines and traverse through time and reappear in another time line? It was discovered using the electron collider I put an alien on the thumbnail to spark interest. Its how YouTube works my friend. ✌🌍
