I really like this one too! It seems like there is an invisible perspective, that goes through the sky, it's really pretty. Although the sign is from nowadays, it looks like a futuristic photo. That's the way i see it
This is the limit because the human being haven't constructed a faster rocket yet and in the future the only limit will be our imagination and our short life.
Anyway! Back to the photo. Really like the angle here. The contrast between the sign and the sky catches the eye. It's really creative and GREAT job!
