Scale of the Universe
Compare the dimensions of particles, organisms, familiar objects, planets, and galaxies. Read the measurement named on each card, then choose larger or smaller. Images are not shown to scale. Some sizes are representative estimates or theoretical bounds, as explained in How to Play.
About this game
Compare the dimensions of particles, organisms, familiar objects, planets, and galaxies. Read the measurement named on each card, then choose larger or smaller. Images are not shown to scale. Some sizes are representative estimates or theoretical bounds, as explained in How to Play.
Tips for playing
Compare the stated dimension rather than the apparent image size. Convert units when needed: a micrometre is one thousandth of a millimetre. A length, a height, and a diameter describe different measurements.
