the electron is currently theorized to be a point particle. that means its radius is 0.
the milky way is significantly larger than the andromeda galaxy.
lots of inaccuracies here.
i doubt this is even a quarter half of the size of the univers
Wow. This awesome. Liked the descriptions. If you make a sequel, here are my suggestions: I would like to see more of the illustrations (eg the Virgo Cluster or the Local group), maybe it would be better to center them and let them slowly appear when you zoom out. Or you can open their image in a new window, zoomable. A drag&drop concept would be good, to put some things at nearly the same size in comparision. Some star trek and other science fiction reference could be neat (as suggested by tamukiro), since this is where most of us heard of some of the more distant and greater space phenomena. Since you added Minecraft world (VERY cool:) I suggest also some famous fictious spaceships and stations...yes star trek, but also 2001, star wars etc. I especially miss the Dyson sphere^^ You could also add different forces, gravitaton of earth, the solar wind, etc and who discovered the different objects and forces first. Thanks for this awesome educational piece of work!
I think it's really great how you could make this. This must've taken a lot of time and research. I love to just scroll through all of the items/lengths to see the huge difference in size.
I think the best part about this is that it looks really nice, and structured. It's immediately clear what this flash is about, and having just one button makes the game organized.
The soft music adds to that. It's nice to hear, and not distracting.
I don't know if this can be used as a study book kind of thing though. It would be nice if we could imput a length (like 10^-27), and get the item or length we're searching for. And maybe even an object. resembling it. If you're looking for something, it takes a bit long to search for it now.
Maybe you could even make a small dictionary with a few items and their lengths, so you scroll to it by typing its name?
Another minor thing I dislike is that some of the items don't blend in too well with their environments. Especially from 10^23 to 10^27, it was clearly divisible it were google images. If you could make the background a bit darker, the feeling of space would be created more, and the pictures would look nicer compared to the background.
Nonetheless it's a great gadget, and not something you see often.
