Date of the Vikings’ First Atlantic Crossing Revealed by Rays from Space

by Msnbctv news staff



Christopher Intagliata: Precisely 1,000 years in the past, within the 12 months 1021, a Viking or two or three seemingly wandered across the very northern tip of Newfoundland, reducing down bushes … 

Michael Dee: … for clearing a specific spot or for gathering wooden that may have been used as timber for building or for boat restore. They have been cautious to verify their ships have been seaworthy.

Intagliata: Michael Dee is a geoscientist on the College of Groningen within the Netherlands. He says it isn’t information that the Vikings made it to North America round this time. Scientists and students have surmised as a lot from archaeological stays in Newfoundland and by scrutinizing historic texts just like the Icelandic sagas.

Dee: One will not be actually certain how literal one can take the Icelandic sagas. They include numerous not solely inaccuracies, numerous issues which are clearly fantastical—issues like useless folks talking to them, and so forth.

Intagliata: However now Dee and his colleagues have been in a position to give you a exact date—the 12 months 1021—primarily based on proof these Norse guests left behind: particularly, a stump, a log and a department. Wooden anatomists have decided that sure surfaces of that wooden should have been reduce by steel blades—a Viking know-how the native Indigenous persons are not identified to have shared.

And Dee’s staff was ready to make use of a cosmic incidence—a unprecedented bathe of high-energy particles from house across the 12 months 993—so far the felling of the bushes. You see, that bathe of cosmic rays created an abundance of radiocarbon. When taken up by bushes, it left an enduring signature in tree rings—giving the scientists a key to pinpoint the 12 months 993 within the three wooden samples utilizing radiocarbon courting.

Dee: And then you definitely see what we now have to do is depend the rings from there to the sting. It’s important to know the place the sting is, the bark edge. And then you definitely’ll know that was the final development 12 months of the tree, or the felling date of the tree. And it simply so occurred in all three circumstances it was precisely the identical 12 months: 1021 A.D.

Intagliata: The small print are within the journal Nature. [Margot Kuitems et al., Evidence for European presence in the Americas in AD 1021]

The 12 months 1021 due to this fact marks the primary time we all know of that Europeans set foot within the Americas. However because the authors write, it additionally marks “the earliest identified 12 months by which human migration had encircled the planet.”

Dee: Ever since shifting out of Africa by means of Europe and Asia and throughout the Americas, no one had bought throughout the Atlantic Ocean, so by this date, we all know the Atlantic Ocean was crossed for the primary time.

Intagliata: However—as we all know—it wouldn’t be the final.
