I found a website recently. One of the best that I've ever seen.
It's completely made of Flash and it looks super cool. The website gives information about different man-made creations, inventions, discoveries and naturally occurring objects around the world. Not only around but ranging from the largest to the smallest objects that exist in the universe.
A scroll bar is present at the bottom that lets us move from the
smallest to the largest objects and vice-versa. Clicking on the objects
will then display a small window at its side. The window will give
information about the object like where it was
found/discovered/invented/exists etc. It's dimensions are also displayed
and also the significance of the object can be read on the window.
The size of the state of the object can be viewed just above the scroll
bar at its right. It would be 10 to the power of a number. The number
would be positive or negative going by the size of the state of the
object. The sizes vary from billions and billions of metres from +ve to
-ve. (Never even heard of one size called yottameter which is 10 power 24
meters). This and many many other types of information has been given
out from this website.
The link is here.
