Testing the multiverse hypothesis requires measuring whether our universe is statistically typical among the infinite variety of universes. But infinity does a number on statistics.


The theory of eternal inflation casts our universe as one of countless bubbles in an eternally frothing sea.

Can our brains help prove the universe is conscious?


If we can find the answer, it may complete our understanding of space and time.

Beautiful landscape to brighten up your Monday (and hopefully your entire week). Happy Monday, Earthlings!

Ingenuity's Successful Fifth Flight

NASA’s Ingenuity Mars Helicopter’s fifth flight was captured on May 7, 2021, by one of the navigation cameras aboard the agency’s Perseverance rover.

Ingenuity Spots Perseverance From the Air

NASA’s Perseverance Mars rover is visible in the upper left corner of this image the agency’s Ingenuity Mars Helicopter took during its third flight, on April 25, 2021.

First Aerial Color Image of Mars

This is the first color image of the Martian surface taken by an aerial vehicle while it was aloft. The Ingenuity Mars Helicopter captured it with its color camera during its second successful flight test on April 22, 2021.

Five mysteries the Standard Model can’t explain: symmetrymagazine.org/article/f

Our best model of particle physics explains only about 5 percent of the universe.

19 hours have passed and still no confirmation if this tweet is legit or fake. Two things: 1.) @CNSA_en is not the official China account and 2.) the China account is hacked. I choose to believe the former. You can resume your normal day to day life now.

Earth humans successfully flew a helicopter, called Ingenuity, on another planet.

Ingenuity's First Black-and-White Image From the Air

NASA’s Ingenuity Mars Helicopter took this shot while hovering over the Martian surface on April 19, 2021, during the first instance of powered, controlled flight on another planet. It used its navigation camera, which autonomously tracks the ground during flight.

NASA's Ingenuity Mars Helicopter Succeeds in Historic First Flight

The small rotorcraft made history, hovering above Jezero Crater, demonstrating that powered, controlled flight on another planet is possible.

Perseverance's Selfie with Ingenuity

NASA’s Perseverance Mars rover took a selfie with the Ingenuity helicopter, seen here about 13 feet (3.9 meters) from the rover in this image taken April 6, 2021, the 46th Martian day, or sol, of the mission by the WATSON (Wide Angle Topographic Sensor for Operations and eNgineering) camera on the SHERLOC (Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals) instrument, located at the end of the rover's long robotic arm.

Mastcam-Z Gives Ingenuity a Close-up

NASA’s Ingenuity Mars helicopter is seen here in a close-up taken by Mastcam-Z, a pair of zoomable cameras aboard the Perseverance rover. This image was taken on April 5, the 45th Martian day, or sol, of the mission. A secondary set of anaglyph images are included for use with red-blue 3D glasses.

Ingenuity's First Color Snap

This low-resolution view of the floor of Mars’ Jezero Crater and a portion of two wheels of NASA’s Perseverance Mars rover was captured by the color imager aboard the agency’s Ingenuity Mars helicopter. The image was taken on April 3, 2021, while the solar-powered rotorcraft was still beneath the rover after being deployed. A few higher-resolution images are expected to be acquired by this imager during each of Ingenuity’s test flights.

NASA's Mars Helicopter Survives First Cold Martian Night on Its Own

Making it through the frigid Martian temperatures after being deployed by NASA’s Perseverance rover is a major milestone for the small rotorcraft.

What is a particle? In one hypothetical answer, the properties of space-time — its robustness, its symmetries — essentially come from the way 0s and 1s are braided together.
