No, it can't. It's never been done before, and it never will.
Once again, you're demonstrating that you don't know anything about physics.
There are multiple challenges and dangers with long-distance space travel:
- *Life support*: We need oxygen, water, food and waste disposal. Our life- support supplies and equipment will add a lot of mass. We also need an energy source to power on-board equipment, which adds more mass.
- *Radiation*: Space is full of dangerous radiation. We will need shielding to protect us, which adds more mass.
- *Micro-gravity*: The human body is adapted to gravity. Low or no gravity is harmful. Generating pseudo-gravity by rotation has many issues.
- *Thrust*: We need some kind of engine and propellant to accelerate, decelerate, and maneuver in space. Again, this adds mass to the vehicle. And the rocket equation applies: we need propellant to accelerate propellant.
Not only that, but the energy that you would need to extract and transport helium from the Sun, Jupiter, or wherever else would be ridiculously expensive. You could never make it cheap enough to justify doing it. That's why we should use the Helium that we have now most efficiently.
> Gasoline can also be made.
Oil is a non-renewable resource.
> Everything is technically non-renewable.
Sure, just arbitrarily redefine words what you want them to mean.

Where can I subscribe to your newsletter, where can I donate. I need this alpha. > That's why we should use the Helium that we have now most efficiently. Oh thank you doc / king. Thank you for telling us this. We really need YOU (or your king) to tell us how to use shit on the planet. And obviously it's ALL YOUR shit, it all belongs to YOUR tribe, not my tribe. Obviously. > Gasoline can also be made. > Oil is a non-renewable resource. https://www.thedrive.com/n...-out-of-thin-air I've lost count, a long time ago, about how many crazy things you said that were demonstrably obviously false. You're a waste of time.
