These two videos of other solar system models are great:

Here's a Cody's Lab video showing a "to-scale" solar system. https://www.youtube.com/watch?v=dCSIXLIzhzk

It's astounding that astronomers have mapped out the skies just by looking up. It's like as if I mapped out my entire city just by looking out the windows of my house.

If your city was 99% empty by volume and your house rotated every day it wouldn't be THAT difficult :)

"We can only speculate as to what is on the far side of the house on 123 Anytown Road. Human exploration is needed."

Cody put a few solar system objects on a stadium, with distances to scale, the sun is represented by a pea. He then proceeds to drive cross country to put on the closest stars.

The stars will pass BY each other. The galaxies will pass THROUGH each other without collisions.

There are many youtube videos that try to visualize the incomprehensible scale of space. Here is one just for our solar system https://www.youtube.com/watch?v=dCSIXLIzhzk

Anyone who thinks we'll ever travel to another solar system really truly fails to understand the distances involved.

The furthest humanity has ever travelled, by way of analogy, is a couple of millimeters - to the moon. The nearest star system relatively speaking is another 200 kilometers further.

And sure you can appeal to the "well you never know what humans are capable of in the future" line of thinking, but that's really just star trek fantasy - there's not the remotest chance, nada, never.

Here's a fun video that explains and will totally dismiss any idea that we'll ever get there - apart from Star Trek fantasy:

I doubt that we'll build generational ships with current humans inside. Instead we'll have to find out ways to prepare us ourselves for the journey. E.g. hibernation. Something that changes our perception of time. The Milky way is 100k light years apart. If we manage to travel at an average 0.01c, we can reach any point in the Milky Way in 10 million years. That's still more than ten times shorter than the time span of the dinosaur occupied earth.

Are you really seriously suggesting that noone dreaming of interstellar travel appreciates interstellar distances?

⬐ devoply

To quote dumb and dumber, so you mean there's a chance?

Not everyone, but most people.

I think anyone dreaming of interstellar travel and not also dreaming about human life extension is being silly. Until and unless we can live for at least 10Ky there's almost no point in going beyond the heliopause, unless you just want to live like an anchorite.

Just going to space within our own Solar System will be like living (not just working) in a very unsafe mine.

Without some sort of "magic" FTL and/or "stasis field" we are as trapped as a beetle on Hawaii.
