Beskrivelse

Over the past century, astronomers have speculated about the existence of a mysterious 9th planet lurking in the outer reaches of our Solar System. Although we've never directly observed the elusive Planet X, researchers keep finding more strange phenomena that seem to support its existence. Scientists believe that Planet X, also referred to as Planet 9, is about 17 times bigger than Earth, and made entirely out of gas.

What If Earth was Flat But Gravity Still Existed?

What if Earth was flat... but gravity still existed? In this mind-bending science experiment, we explore what would really happen if our planet were shaped like a giant disc, while gravity kept pulling everything “down.” Support us on Patreon: patreon.com/whatifshow/membership [https://www.patreon.com/whatifshow/membership] Get the What if book: bit.ly/ytc-the-what-if-100-book [http://bit.ly/ytc-the-what-if-100-book] Join this channel to get access to perks: youtube.com/channel/UCphTF9wHwhCt-BzIq-s4V-g/join [https://www.youtube.com/channel/UCphTF9wHwhCt-BzIq-s4V-g/join] Interested in sponsoring our episodes or collaborating?

What if You Traveled to Earth 2.0?

Discovered by NASA’s Kepler Space Telescope, Kepler-452b is one of the most Earth-like exoplanets ever found. It orbits in the habitable zone of a Sun-like star, about 1,400 light-years away, the region where temperatures could allow liquid water to exist.

What Happens When You Drop a Black Hole into a Pool of Water?

episode If Saturn Replaced Our Moon cover

If Saturn Replaced Our Moon

A huge gas giant suddenly appears in the sky. You look up in wonder. It's beautiful. And terrifying. The second Saturn replaces our Moon in its orbit, Earth would just as suddenly stop being a planet. We would become a moon. Yeah, scientists would have to reclassify Earth. That is, if any scientist, or any humans at all, could survive this planetary switch. Because Earth days would now be numbered.
