///@physicsgene: The universe is everything. It includes all of space, and all the matter and energy that space contains. It even includes time itself and, of course, it includes you. Earth and the Moon are part of the universe, as are the other planets and their many dozens of moons.As compared to known Universe, we are even smaller than the size of an atom, our entire galaxy which is 100000 light years across is size of dust particle compared to Universe and its funny how people think we are alone.Trillions of galaxies out of trillions in the known Universe are Unknown because we know only about few hundreds or thousands.If the Universe is Ocean, our knowledge is limited up to teaspoon full of water and watching the spoon full of water, we can’t claim there’s no shark in the ocean.Via @spaceinnutshell
