This is for worldbuilding purposes. I'm not exactly a "science dude", so I'd like to get a better idea of our solar system and beyond, preferably with links to layman-friendly explanations on things like:

• distances and travel time not only having Earth as a starting point, but from any given point to another
  • if at all possible, including hypothetical alien and/or future technologies
• Earth-like planets
• locations that might be able to sustain life, and which kind of life it could sustain
• locations that, while unsuitable to carbon-based life, might receive enough energy to sustain artificial intelligence

I remember there's some kind of simulator or engine, that can run on a computer... anyone remembers the name? And would it run on an aging laptop with an i5 processor and Intel HD4400 integrated graphics?

Thanks!

EDIT: I guess I'll make this question a bit more approachable, so... what are some YouTube channels that can teach me more the basics of our solar system, nearby systems, the Milky Way, and how all of those are linked together?.
