☆ 8 ways new technology changed the way we think about ancient Egyptian mummies
▼ + stars: | 2024-09-25 | by ( Marianne Guenot | Jenny Mcgrath | ) www.businessinsider.com time to read: +1 min

Egyptology has come a long way from Victorian mummy-unwrapping parties. The mask of King Tutankhamun, which was damaged and glued back together, is seen at the Egyptian Museum in Cairo. Some royal mummies were unveiled by running a knife straight from their head to their toes, with little care. The way early excavators treated mummified remains partly explains why the remains of King Tutankhamun, a Pharaoh of the 18th dynasty buried with the famous golden mask, are in such poor shape today. "CT scanning and X-rays are the basic ways of searching mummies nowadays because you cannot unwrap mummies in museums," Ejsmond said.

The Harvard professor's research is bankrolled by tech tycoons "pissed off" at academia's dogma. But this boundary-pushing is exactly why he's backed Loeb's research. AdvertisementDesch, the astrophysicist from Arizona University, posted a critique of Loeb's work on arXiv alleging "multiple fatal flaws with the manuscript's arguments." Asked whether he no longer believes in a possible technological origin for the meteor, Loeb said they need to investigate further. As he plans more extravagant expeditions to prove the origin of the interstellar meteor, Loeb likens his critics to crows pecking at the neck of an eagle.

☆ Mars could be creating 'giant whirlpools' deep within our planet's oceans
▼ + stars: | 2024-03-13 | by ( Marianne Guenot | ) www.businessinsider.com time to read: +5 min

Mars may be 140 million miles away, but its gravitational pull could be impacting Earth's oceans. Scientists at the University of Sydney in Australia believe the red planet's tug is creating "giant whirlpools" in the oceans called eddies, which can shift the deep-sea floor. This, they claim, is part of a 2.4-million-year climate "grand cycle" on Earth that has been ongoing for at least 40 million years. The red planet's orbit and ours are locked in an intricate dance, and every so often, these line up so that Mars' gravitational pull on Earth is just a little more intense — this is called resonance. This information is crucial when refining models helping us see how our planet's intricate climate will progress over time.

The galaxy, which is bigger than the Milky Way, could upheave what we know about how dark matter shaped the early universe. Light travels at a fixed speed through space, so the image of these early galaxies in the past is only reaching us now. According to current cosmology models, that should not be possible because dark matter is not supposed to have been mature enough at that time.
