Astronomers have just discovered the first known "Einstein zigzag."
Due to a rare, lucky cosmic alignment, the combined gravity of two galaxies bent light like spaghetti & split a distant quasar into six different images.
This six-part image could allow a very accurate measure of the expansion of the universe.

🔴 People everywhere are head down, lost in the oblivion of infinite scroll. Just stop and let the moment breathe

“As much as I want to blame Silicon Valley for everything, the best I can accuse the tech industry of is building a profit-hungry machine exploiting the very human difficulty of being alone with one’s thoughts. Which is still pretty bad, sure, but let’s be clear: chronic inattention predates the internet.”

@zulutoo I tried, but no option comes up to follow.
@fox Unfortunately, comprehension of technical concepts in French is above my level. Thank you for the offer.
I have not used 'Sepia Search' before, I shall give it a try. Thank you for the suggestion.
Thank you for commenting. I used the search facility on Peertube and could not really find anything that was interesting. I will follow premodernist and see what comes.
🔴 Just tried using Peertube, however could not find anything on the platform I wanted to watch. My interests include videos based on science or history. Is there some secret I am missing?
🔴 Magnetic North Pole moves closer to Russia in way never seen before by scientists
Jabed Ahmed
"The magnetic pole moved along the northern Canadian shore for centuries, Dr Brown said. It drifted into the Arctic Ocean in the 1990s, and after that, it accelerated and headed towards Siberia."

A stunning #IceAge masterpiece: a big cat (thought to be a snow leopard) carved in mammoth ivory more some 40,000 years ago! Length 8.7 cm, found at the Vogelherd Cave on the Swabian Jura.

🔴 🇯🇵 J. R. Seeley And Japan's Pacific Expansion
"Korhonen's essay began with a striking claim:
The first person ever to use the term Pacific Age was the Japanese political economist Inagaki Manjirō. Inagaki studied the history of Great Britain's expansionary policies under the guidance of the British historian John Robert Seeley at Cambridge University during the late 1880s. Seeley had been influenced by the German geographer Carl Ritter. Through Inagaki a certain style of European nineteenth-century visionary rhetoric was introduced into discussions about the Pacific future. That is an interesting point in itself, but even more interesting are the shifts in perspective that resulted from this transference of concepts into a different context."

@philip_cardella Can see your toot. I use the web version of QOTO and currently have no problems.

Not a bot, just a rather corpulent male fifty years of age; a very, very slow ignoramus who reads occasionally.
Toots are #humanities, #science, #nonfiction, #book, #map, #chart and #graph related. Some toots containing #videos may also find their way into the timeline.
Toots or follows or boosts or mentions ≠ endorsements of any particular notion or notions.
