In this universe, we are just a drop in the cosmic ocean.
Everything mankind has ever known is confined to a spheroid only 13,000 km in diameter.
Even other planets regularly occupy thousands of times the volume of Earth.
Stars start out as small as the largest planets, but grow much larger.
The largest supergiant stars have diameters exceeding billions of kilometers.
They are comparable in size to the event horizons of the most supermassive black holes.
But even the largest individual objects are no match for cosmic collections of objects.
Around each star system, the Oort clouds extend for several light years: tens of trillions of kilometers.
The stars themselves come together in large galactic assemblages.
At a minimum, they have thousands of stars, spanning hundreds of light years.
The largest galaxies contain more than 100 trillion stars, with Alcyoneus, a record, spanning an unprecedented 16 million light-years.
At even larger scales, galaxies cluster together, forming structures up to hundreds of millions of light-years in diameter.
The largest superclusters, voids and filaments – although not gravitationally bound – span billions of light years.
Overall, our observable universe spans 92 billion light-years.
But the unobservable Universe must be at least hundreds of times larger.
For all we know, the Universe may even be infinite.
