Description

What’s up with the fourth dimension? Neil deGrasse Tyson and Chuck Nice explore the dimensions, worldlines, and what it would mean to be 4D. Learn about time and space and how we navigate through both. What would a 2D world be like for two-dimensional people? We break down what it's like for 3D beings to interact with the second dimension and what it would be like for 4D beings to interact with the third dimension. Plus, we discuss flying cars and whether we already have them.

I never know what I want explained until I hear him explain it.

"We are prisoners of the present.. forever transitioning between an inaccessible past and unknowable future". 🔥

I like Chuck's closing statement... _"In another dimension, we'd have all the time in the world."_ ...That is profoundly astute.

The ability to turn a complex concept to a comprehensible one is truly astounding. Such a master teacher.

The way Chuck passively absorbs Neil’s science talk is probably the best part. They make a great pair lol

I’m not the smartest book on the shelf but it’s amazing how much you can understand if the right person explains it. It’s still a hard concept to grasp but I think I understood it as much as anyone could

1. The amount of connection and humor in this convo really brightened my day 😂☀️ 2. Isn't our ability to remember experiences in the past and imagine experiences in the future somewhat in alignment with the 3D being moving in and out of the 3D cell without moving spaces? It's not a physical change, but our brain is still experiencing it as if it's real. I suppose then it is a physical change, but only to our brain 🧠 🤔 3. And important reality Neil is highlighting with the flying cars is that we are already operating vehicles in multiple dimensions and traffic exists at every one of those levels (subway, tunnels, freeway, overpasses). If we had (more) flying cars, there would just be traffic there too eventually. The only way to eliminate traffic is to have less vehicles moving thru the same space and the same time. If we all intentionally reduced our world lines, even a little bit to not be on freeways and overpasses, or even in cars, there would be less traffic. And people wouldn't even want flying cars, because let's face it, most people don't really Need them
