I think this comes down to how we're using the words "we". Galileo transformed how "we" see the world, but not a whole lot of people at the time appreciated the implications of what he was saying. I think we need to keep looking for ways to answer the big questions because it elevates us. But it's often unevenly distributed in space and time, unfortunately. Basically, I'm saying that the search for alien life is just…
You're right, of course. The video amused me. I got to thinking - what if the first communication was just spam!

But why can't Alice keep rolling the die until it gets to a state that she and Bob agree is a part of an encoding scheme? Is it because she needs to read the number on the die to know whether to stop rolling it, but by reading (measuring) the number, she is effectively re-rolling (collapsing) it, so she could never know when to stop rolling it? In other words, she could stop after she measures a state, but the curren…
You can only roll the die once. Alice and Bob have a dozen dice. They agree that if they roll a 4, that's the signal for "attack at dawn" and Alice has decided that she wants Bob to attack at dawn. Alice rolls the 12 dice, and at the agreed upon time, Bob also rolls his 12 dice. The sequence they get is 1,5,3,2,2,4,6,5,1,2,1,6. The 6th die is a 4, which is the signal that Alice wants to send. How does Alice signal to…
Thanks for the explanation. :) It makes sense, at least insofar as any of this can possibly make sense...
