Why one Harvard scientist thinks there might be alien technology on the ocean floor

There are many common explanations for why 'Oumuamua accelerated; outgassing, or the release of previously stored gas, is one of the most well-liked ones.

Astronomers are interested in CNEOS 2014-01-08 because they think it might very probably be the first interstellar object of its size to be detected by humans and strike the Earth.

Loeb is also going above and beyond; he is in charge of a $1.5 million mission to recover CNEOS 2014-01-08 fragments.

When challenged about the possibility of extraterrestrial technology, Loeb wrote to Salon that the first interstellar meteor, CNEOS 2014-01-08, is a rare outlier for two reasons.

"By tracing its route back in time, we know that [CNEOS 2014-01-08] was moving faster than 60 kilometres per second outside the solar system," says the first justification.

According to Siegel, there are more plausible theories, such as the idea that "this is an object that came from our solar system and, with a poorly determined impact velocity, just came from our solar system like everything else that hits Earth from space," which is more likely to be true.

These peculiar characteristics distinguish CNEOS 2014-01-08 from its more commonplace meteoroid relatives, which normally come from our solar system.
