Did you know that in roughly 50,000 years, the Big Dipper, one of the most easily recognizable asterisms of the night sky, will no longer be visible in its current shape? Yep, it will completely change its shape and face the opposite way.
So sit back, relax, and enjoy the view while you still can 🥂😋
Recently I stumbled into some debate over the physics of time. I was quite surprised to find out that according to our best theories of physics, the universe appears as a fixed block where time only appears to pass. In that so-called block universe we live, all things that have happened, that are happening or are going to happen they already exist and our passage through time is a function of our perception, or other illusion. This bothered me because it seemed to suggest that the future is already set in stone. Plus, they said nothing about that precious moment of ours, the point of now. What do you guys think, are we in the future yet? 🤔
