If I were immortal, would the distance between the atoms and molecules of my body be greater now than they were 10B years ago due to the cosmic expansion? And, even if they were, would any measurement system we have be able to detect it?
In answering a question today, you stated that a chemical drive could theoretically attain relativistic speeds, but is that REALLY the case? Wouldn't you reach a point where the size of the drive needed vs the amount of fuel needed would quickly cause the drive as well as the fuel to approach infinity?
Of course, you would need an infinite amount of fuel.
Why Crew Dragon and Starliner? Old saying: 1= none and 2 = 1.
