In line with an earlier post talking about the the scale of the solar system checkout if the moon were 1 pixel gives you a visceral feel for the size of the solar system. I only made it out to Saturn. It took a long, long time to scroll.
It makes you imagine how long an interplanetary trip would take. There is a lot of nothing. It was so boring just scrolling for a few minutes. Just black. No air.
Traveling from Earth to Mars would take about seven months. Earth is at 150M km; Mars is at 225M km.
Jupiter is a 13 month trip and is at the kilometer marker 750M. No rest stops.
I was under the impression that the Universe would expand, contract, big bang, expand, contract, etc. Apparently there are competing theories where things just fade away. Dark Energy seems to account for the theoretical change.
Anyway, here’s a video explaining the competing theories:
Here is a table if you wanted to make a scale version of the solar system. It’s based on making the Earth a 1in sphere and then gives how far from the Sun each planet should be and how big of a ball to use for each planet.
This is from frink a programming language based on accurate representation of units. If you are into really nerding-out take a look at the unit data which describes lots of possible unit conversions.
