Let's grant that the stars are scattered through space, hither and yon. But how hither, and how yon? To the unaided eye the brightest stars are more than a hundred times brighter than the dimmest. So the dim ones are obviously a hundred times farther away from Earth, aren't they?
Nope.
That simple argument boldly assumes that all stars are intrinsically equally luminous, automatically making the near ones brighter than the far ones. Stars, however, come in a staggering range of luminosities, spanning ten orders of magnitude ten powers of ten. So the brightest stars are not necessarily the ones closest to Earth. In fact, most of the stars you see in the night sky are of the highly luminous variety, and they lie extraordinarily far away.
If most of the stars we see are highly luminous, then surely those stars are common throughout the galaxy.
Nope again.
High-luminosity stars are the rarest. In any given volume of space, they're outnumbered by the low-luminosity stars a thousand to one. It's the prodigious energy output of high-luminosity stars that enables you to see them across such large volumes of space.
The Heart of Gold fled on silently through the night of space, now on conventional photon drive. Its crew of four were ill as ease knowing that they had been brought together not of their own volition or by simple coincidence, but by some curious perversion of physics- as if relationships between people were susceptible to the same laws that governed the relationships between atoms and molecules

While the Copernican principle comes with no guarantees that it will forever guide us to cosmic truths, it's worked quite well so far: not only is Earth not in the center of the solar system, but the solar system is not in the center of the Milky Way galaxy, the Milky Way galaxy is not in the center of the universe, and it may come to pass that our universe is just one of many that comprise a multiverse. And in case you're one of those people who thinks that the edge may be a special place, we are not at the edge of anything either.

Each of us is aware he's a material being, subject to the laws of physiology and physics, and that the strength of all our emotions combined cannot counteract those laws. It can only hate them. The eternal belief of lovers and poets in the power of love which is more enduring that death, the finis vitae sed non amoris that has pursued us through the centuries is a lie. But this lie is not ridiculous, it's simply futile. To be a clock on the other hand, measuring the passage of time, one that is smashed and rebuilt over and again, one in whose mechanism despair and love are set in motion by the watchmaker along with the first movements of the cogs. To know one is a repeater of suffering felt ever more deeply as it becomes increasingly comical through a multiple repetitions. To replay human existence - fine. But to replay it in the way a drunk replays a corny tune pushing coins over and over into the jukebox?

A mathematician is an individual who calls himself a 'physicist' and does 'physics' and physical experiments with abstract concepts.

Among all the occurrences possible in the universe the a priori probability of any particular one of them verges upon zero. Yet the universe exists; particular events must take place in it, the probability of which (before the event) was infinitesimal. At the present time we have no legitimate grounds for either asserting or denying that life got off to but a single start on earth, and that, as a consequence, before it appeared its chances of occurring were next to nil. ... Destiny is written concurrently with the event, not prior to it... The universe was not pregnant with life nor the biosphere with man. Our number came up in the Monte Carlo game. Is it surprising that, like the person who has just made a million at the casino, we should feel strange and a little unreal?
