MU69 is Flat, and No One Knows Why - SciShow News
MU69 seems to be much flatter than we thought and the Gaia space telescope can tell us where galaxies have been and, maybe, where they're going.

Why the Universe Needs Dark Energy
We know the universe will continue to expand forever, so now we can begin to complete the first Friedmann equation, and determine the shape and geometry of our universe. At first glance, it would seem that the equation doesn't quite add...

TED-Ed: Pizza physics (New York-style) - Colm Kelleher
People love eating pizza, but every style of pie has a different consistency. If "New York-style"--thin, flat, and large--is your texture of choice, then you've probably eaten a slice that was as messy as it was delicious. Colm Kelleher...

Why Are Snowflakes Flat
We’re told that all snowflakes are unique. But when you really think about them, snowflakes get even more interesting - as ice crystals forming in 3D space, why are snowflakes basically 2D?

Pankaj Ghemawat: Actually, the world isn't flat
It may seem that we're living in a borderless world where ideas, goods and people flow freely from nation to nation. We're not even close, says Pankaj Ghemawat. With great data (and an eye-opening survey), he argues that there's a delta...

Can a Circle Be a Straight Line?
On this week's episode of Spacetime, Gabe talks about what it actually means for a line to be straight so we can better understand what we mean by the idea of "curved Spacetime". This is Part One of our series on General relativity, so...

Guess That Tree! Science for Kids
Jessi and Squeaks just spent the day hiking and sketching evergreen trees in their field journals! A lot of evergreen trees look pretty similar, but Jessi knows some fun ways to tell them apart. Join us to find out how!

How Cosmic Inflation Flattened the Universe
Although much of the Big Bang Theory is widely accepted to be true, it only gets us part of the way there. Observable truths such as the CMB and the flatness of our universe reveal that there is no way the universe has been expanding at...

Danger! Falling Objects
So, what would happen if you dropped a hammer and a feather at the same time, from the same height? Well, the hammer would hit the ground first, right? But why? You might think it's because the hammer is heavier, or has more mass than...

Why Do the Planets Orbit in the Same Plane?
While there is a little wiggle room, the planets in our solar system really are orbiting on mostly the same level. Why do they do that?

How Can the Universe Be Flat?
Can geometry predict the future? Cosmologists think the overall curvature of universe can tell us secrets about how it will eventually end.

TED-ED: The death of the universe - Ren_e Hlozek
The shape, contents and future of the universe are all intricately related. We know that it's mostly flat; we know that it's made up of baryonic matter (like stars and planets), but mostly dark matter and dark energy; and we know that...
