US startup beats IBM to reach 1,000 qubit milestone
IBM's announcement of a 1,000+ qubit computer is expected in the next few weeks but the startup might be a few leaps ahead.
Scientists widely agree that an ancient planet likely smashed into Earth as it was forming billions of years ago, spewing debris that coalesced into the moon that decorates our night sky today.
The theory, called the giant-impact hypothesis, explains many fundamental features of the moon and Earth.
But one glaring mystery at the center of this hypothesis has endured: What ever happened to Theia? Direct evidence of its existence has remained elusive. No leftover fragments from the planet have been found in the solar system. And many scientists assumed any debris Theia left behind on Earth was blended in the fiery cauldron of our planet’s interior.
A new theory, however, suggests that remnants of the ancient planet remain partially intact, buried beneath our feet.
Molten slabs of Theia could have embedded themselves within Earth’s mantle after impact before solidifying, leaving portions of the ancient planet’s material resting above Earth’s core some 1,800 miles (about 2,900 kilometers) below the surface, according to a study published Wednesday in the journal Nature.

“These (LLVPs) — they’re an area themselves of very active research,” said Jacobson, who was not involved in the study. And the tools used to study them are constantly evolving.
The idea that Theia created the LLVPs is no doubt an exciting and eye-catching hypothesis, he added, but it’s not the only one out there.
One other theory, for example, posits that LLVPs are actually heaps of oceanic crust that have sunk to the depths of the mantle over billions of years.
“I doubt the advocates for other hypotheses (about LLVP formation) are going to abandon them just because this one has appeared,” Jacobson added. “I think we’ll be debating this for quite some time.”
