is The Universe Flat?

Описание: What is the true shape of the universe? Is it curved like a sphere, stretched like a saddle, or flat like an endless sheet?

In this video, we will explore the three leading models of the universe’s geometry—closed, open, and flat—with real-world physicists behind each idea, including Albert Einstein, J. Richard Gott, and George Efstathiou.

But we’re not stopping there.

We’ll journey into the mysterious and mind-bending No Boundary Proposal by Stephen Hawking and James Hartle, a theory that suggests the universe may have no beginning, no edge, and no boundary at all.

Plus:
Why the universe looks flat
How cosmic inflation ties into all this

Whether you're a science nerd or just cosmically curious, this 6-minute ride will stretch your brain across time and space—literally.

Watch now and see if you can wrap your head around the shape of the entire universe.
