Archaeologists just pried another secret of our past from the clutches of the earth, welcoming a new human species to our growing family tree.

This discovery began with an ancient foot, or what was left of one. A foot bone, called the third metatarsal, was found in the Callao Cave on the Philippine island of Luzon back in 2007.

The oldest known Homo sapiens remains, found nearby on Palawan Island, were dated to 30,000 to 40,000 years ago. But this mysterious foot is older, dated to 67,000 years ago.

In a new interview, MIT researcher Rizwan Virk told Digital Trends that, in his estimation, we’re probably living in a simulation.

“I would say it’s somewhere between 50 and 100 percent,” he told the site. “I think it’s more likely that we’re in simulation than not.”

European scientists looking for some of the oldest ice on the planet have homed in on a particular spot in Antarctica, where they will drill more than 1.5 miles (2.7 kilometers) below the surface of the ice.

Over the next five years, the “Beyond EPICA-Oldest Ice” mission will work at a remote location known as “Little Dome C” to start drilling for ice up to 1.5 million years old, the team announced today (April 9) at the meeting of the European Geosciences Union in Vienna, Austria.

“Ice cores are unique for geosciences because they are an archive of the paleo-atmosphere,” said Beyond EPICA’s coordinator Olaf Eisen of the Alfred Wegener Institute in Germany. [Antarctica: The Ice-Covered Bottom of the World (Photos)].

Suppose you throw some object near the surface of the Earth. If the only significant force on the object is the constant downward gravitational force, we call this “projectile motion.” Yes, that tennis ball you loft across the room is projectile motion. Flipping a coin—the center of mass is projectile motion. As you can probably guess, a dude jumping on a moving trampoline is also an example of projectile motion.

For these kinds of motions, the following must be true:
