July 02, 2026 Traveling to Before the Big Bang
Take the entire known Universe, all 93 billion light-years of it. All two trillion galaxies, every star, every planet, every black hole, every quasar, every speck of dust, and you. Then squeeze it all down until it's smaller than a proton. Now, you've got yourself a singularity.

The kind of singularity that was the beginning of our Universe. And that’s where you’re headed. The moment before the Big Bang.

July 01, 2026 What if Planet X Was Actually Real?
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.

June 30, 2026 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.”

June 29, 2026 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.

June 25, 2026 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.
