Excuse me, but I have a question regarding the operation of thrusters in space. Could you please explain what exactly do these thrusters push against when they're operating in the vacuum of space? I understand that in an atmosphere, like Earth's, thrusters expel gas to create thrust, but how does this concept apply in the vast emptiness of space? It seems counterintuitive that something can push against nothing. I'm really curious about the physics behind this, so I'd appreciate your detailed explanation. Thank you.

Excuse me, could you please elaborate on how one might acquire a spaceship using space-related cryptocurrencies? I'm intrigued by the concept and would like to understand the process in more detail. Are there specific platforms or exchanges where these types of transactions take place? What kind of verification or authentication is required? And finally, what are the potential risks and challenges involved in using cryptocurrencies to purchase a spaceship?

Excuse me, could you please clarify if Sputnik, the first artificial satellite launched into Earth's orbit by the Soviet Union in 1957, is still present in space today? I'm curious to know if it's still orbiting our planet or if it has since deorbited and entered the atmosphere, given its historical significance and the fact that it marked the beginning of the Space Age. Thank you for your attention.

Considering the vast expanse of space and the myriad of celestial bodies that populate it, one might wonder: who technically owns space? Is it a collective human endeavor, with nations staking claims to their respective territories? Or does ownership extend beyond terrestrial borders, with private companies and individuals asserting rights to celestial objects? The question of who owns space is a complex one, fraught with legal and ethical implications. As space exploration and exploitation continue to advance, the need for clear guidelines and regulations becomes increasingly urgent. So, who technically owns space? Is it a matter of national sovereignty, private enterprise, or something altogether different?

How can we define the limits of space? Is it an infinite expanse that stretches beyond our comprehension, or is there a specific height that marks the end of space and the beginning of something else? When we send rockets and spacecraft into orbit, how far up do they go? And what happens to them when they reach the so-called "edge" of space? Is it a hard and fast boundary, or is it more of a gradual transition? What challenges do astronauts and engineers face when exploring the vastness of space, and how do they overcome them? Can we ever truly know the answer to the question, "How high up is space?
