Astronomy on the Joe Rogan Experience

“there's a thing called the Taurid meteor stream, which is 30 million kilometers wide and which envelops the solar system.”

The guest claims the Taurid meteor stream is 30 million kilometers wide and is the debris of a 100km-diameter comet that caused a cataclysmic impact on the North American ice cap 12,800 years ago.

“Came in, it was about 50 feet in diameter, which is about, and it came in at a fairly low angle.”

The guest describes the 2013 Chelyabinsk meteor as about 50 feet in diameter, exploding roughly 12 miles (20 km) up and injuring 1,500 people.

“And every 20,000 years, they found a little blip a little dip in The fossil record where we lost some species and people were wondering why could there have b…”

Tyson states that dips in the fossil record showing periodic mass extinctions recur roughly every 20,000 years, which led scientists to hypothesize a companion star to the sun (later dubbed Nemesis).

“So, I'm not quick to call it Planet 9 because it's 20,000 times farther away from the sun than the Earth is.”

Tyson states that the hypothesized ninth planet is 20,000 times farther from the sun than Earth is.

“The Sphinx aligned with, it was looking at the rising sun and behind it the constellation of Leo 12,500 years ago.”

The Sphinx faced the rising sun with the constellation Leo behind it 12,500 years ago.

“now it's Polaris because the extended north pole of the Earth is spiraling in the heavens and it's pointing at different bits of space over a roughly 26,000 ye…”

The precession of the equinoxes completes a cycle of about 25,920 years, with one degree taking 72 years.

“when we work precession into the equation, we find that they're not laid out in the pattern of Orion's belt as it looked in 2500 BC when the pyramids are suppo…”

The three Giza pyramids are laid out matching the pattern of Orion's belt as it appeared in 10,500 BC, not 2500 BC when they were supposedly built.

“and that time is around 12,600 years ago. It's not a single moment, it's an epoch of several hundred years. But the constellation of Leo, it was the age of Leo…”

Hancock claims the constellation Leo housed the rising sun at the spring equinox around 12,600 years ago, aligning with the lion-shaped Sphinx.

“It's 0.6 inches a year... in all of the planets in every solar system is drifting away from their primary at this same exact rate, like 1.5 cm. So this is a un…”

Howard claims Earth and all planets in all solar systems are drifting away from their stars at a fixed universal rate of about 0.6 inches (1.5 cm) per year, part of his 'Terryology' theory of universal expansion.
