Excellent work from Cary and Michael Huang from the site htwins.net! A very interesting interactive application with the full scale of the universe that we know so far. Starting from the quantum foam, the theoretical string and the Planck length, you can use the scroll bar tat the bottom to scroll throughout the various objects of larger size, up the the size of the visible universe! You can also click on the objects to see more info. Again, an excellent work, brilliant idea, unmatched implementation!
