Strangely, âposhliâ (which means âletâs goâ or âletâs head outâ in Russian) is actually the past tense of the verb meaning âTo head off on foot.â In other words, âposhliâ literally means, âWe (or they) headed off on foot.â How can a word which is in the past tense indicate the desire to head off somewhere now?
Earth's mass is approximately 7024597000000000000â 5.97Ã1024 kg (5,970 yg). It is composed mostly of iron (32.1%), oxygen (30.1%), silicon (15.1%), magnesium (13.9%), sulfur (2.9%), nickel (1.8%), calcium (1.5%), and aluminium (1.4%), with the remaining 1.2% consisting of trace amounts of other elements.
The observable universe is approximately 90 billion light years in diameter and the Earth is approximately 12000km in diameter. Let's assume that a grain of sand is 0.5mm in diameter. If we shrink the Earth down to the size of that grain of sand it would become 1/24000000000 (one 24 billionth) its original size. The observable universe, shrunk down by the same factor, would become 3.75 light years in diameter.
