Did an extraterrestrial impact trigger the extinction of ice-age animals?

A controversial theory that suggests an extraterrestrial body crashing to Earth almost 13,000 years ago caused the extinction of many large animals and a probable population decline in early humans is gaining traction from research sites around the world.

The Younger Dryas Impact Hypothesis, controversial from the time it was presented in 2007, proposes that an asteroid or comet hit the Earth about 12,800 years ago causing a period of extreme cooling that contributed to extinctions of more than 35 species of megafauna including giant sloths, sabre-tooth cats, mastodons and mammoths!

It also coincides with a serious decline in early human populations such as the Clovis culture and is believed to have caused massive wildfires that could have blocked sunlight, causing an "impact winter" near the end of the Pleistocene Epoch.

In a new study published this week in Scientific Reports , a publication of Nature, UofSC archaeologist Christopher Moore and 16 colleagues present further evidence of a cosmic impact based on research done at White Pond near Elgin, South Carolina!

The study builds on similar findings of platinum spikes -- an element associated with cosmic objects like asteroids or comets -- in North America, Europe, western Asia and recently in Chile and South Africa.

Nasa to look for alien tech made by advanced extraterrestrial civilisations | Metro News

It has joined up with the Breakthrough Listen initiative to launch a search for 'technosignatures' – the traces of technology which indicate the existence of 'advanced extraterrestrial civilisations'.

These could include massive structures like Dyson Spheres, which are hypothetical 'megastructures' built around stars to harvest their power.

But technosignatures could be signals which seem to be produced by artificial transmitters or perhaps even the engines of alien spaceships.

The Search for Extraterrestrial Intelligence (SETI) drive will utilise the power of the TESS satellite, which is currently searching for planets.

It detects the presence of alien worlds orbiting distant suns by watching a telltale dip in the star's light, indicating a planet's 'transit' in front of it.

'Memory: The Origins of Alien' Review: Extras on an Extraterrestrial - The New York Times

A specialist in documentaries about movies, the director Alexandre O. Philippe gave himself a tough act to follow: His 2017 film "78/52: Hitchcock's Shower Scene" applied a variety of approaches — historical, theoretical, technical — to deconstructing a single sequence in "Psycho."

While it is generally engaging to learn about the influences of the screenwriter Dan O'Bannon or the artistic process of H.R. Giger (who designed the alien), the documentary is at its least fawning when it focuses on technique!

The film is also, in its way, an elegy: An acknowledgment of the prequels " Prometheus " and " Alien: Covenant " implies that, for Scott, the craft of "Alien" was itself a tough act to follow.

Do You Believe Aliens Exist? - The New York Times

In " Area 51 Raid: They Come in Peace, So Far, in Search for Aliens ," Nicholas Bogel-Burroughs writes about the event and its enthusiastic participants. But he also takes on the mystery at the heart of the gathering:

* * *

Seth Shostak is a senior astronomer at the SETI Institute in Mountain View, Calif. (SETI is short for the Search for Extraterrestrial Intelligence.) Researchers there are searching for intelligent aliens — ones that "can at least use a radio transmitter," Mr. Shostak said.

As far as the green little guys that some imagine waddle through Area 51's hallways, Mr. Shostak said there was almost no chance. Secrets like that, he said, would get out.

Why do you think conspiracy theories about Area 51 persist despite denials from the American government? Have you ever wondered what goes on there?
