Quantum entanglement, or The destiny rock - стр. 3

Now, I'm going to make a digression. For example, you look up at the sky at night and you see stars. In fact, many of them may no longer be there. It's their light that's still traveling towards us. And they may have already gone out, that is, died. It is as if, for example, in ancient times one had to walk around the Earth on horseback or on foot for 14 years; if in the seventh year someone from the team died, then the news about it would reach home after 7 years.

So, our universe is actually supposed to be 93 billion light years in diameter. Now, understand this: those edges 14 billion light years away, even with a life of 14 billion years and at that speed, you still wouldn't reach those edges. After all, you only live some 14 billion years, and the universe has expanded during your flight. So let's live longer, like 28 billion years. Is that hard to imagine? Just imagine, you'd live for 28 billion years. It's a miracle. It's unimaginable. Now you probably know what I mean by now. Even with such great unimaginability, you can't reach the edge of the universe. The edge of our universe, because there are many others. Now imagine eternity. Imagine that the universe we've been talking about is just a grain of sand on a beach. A grain of sand among billions and trillions of others. Imagine that? Now imagine you've been alive for a hundred billion years. How cool is that? Now imagine you're traveling to the nearest star at the speed of light. Congratulations, it'll take you four years to get there. So that's at the speed of light, which, by the way, by all the laws of physics, material bodies can't reach. Not that it's technically difficult, no. With the capabilities that space technology has now – it will take us about 40,000 years to get there, and at the speed of light – only 4 years. You might be thinking: how fast, compared to traveling in a rocket. Now imagine, it takes you 4 years to go to a neighboring city. For domestic needs, and more, that's an awfully long time. Notice, it's at the speed of light, which a person can't fly. Not that flying is impossible, it's impossible to reach. Our bodies are material.

Now you have a better idea of the size of the universe. No? Then let's fly through at least our galaxy. In the meantime, I'll tell you in confidence that there are supposedly about 500 billion galaxies, and each galaxy has from 200 billion to a trillion stars. Can you imagine how many galaxies there are? Does it make you dizzy? Then imagine snowflakes in a blizzard. About that many if there's a blizzard all night and all over the region. And think of those grains of sand I mentioned above. In the meantime, we've got another 100,000 years to go through the galaxy. Don't forget, we're only talking about our own. They'd tell you to go to the capital and meet me there in 100,000 years. How cool is that? I think you're already euphoric. That's my way of trying to explain to you a tiny fraction of what's called eternity. You've been flying, flying, flying… billions and trillions of years, and you haven't actually moved. How? It's like this. Because no matter how big you visualize, you're still visualizing a tiny fraction of eternity.
