Oldest material on Earth discovered

Scientists analysing a meteorite have discovered the oldest material known to exist on Earth.

They found dust grains within the space rock - which fell to Earth in the 1960s - that are as much as 7.5 billion years old.

https://www.bbc.com/news/science-environment-51099609


I read that article. I hoped the BBC journalist had been the one who inserted all that woo woo into a science scientific paper report. But alas, it appears that two people with the Field Museum who have regaled and dazzled museum patrons as their day job were the source of that woo woo.

As I make it out the perhaps real dating is 4.6 to 4.9 billion years old:

"Based on how many cosmic rays had interacted with the grains, most had to be 4.6-4.9 billion years old. For comparison, the Sun is 4.6 billion years old and the Earth is 4.5 billion."

That's also happens to the approximate age of the Earth.

:|

Ignore that "however" which follows the above toward the end of the article, it's statistical noise within the second standard deviation:

"However, the oldest yielded a date of around 7.5 billion years old."

Ignore that. That is where the woo woo was inserted. Thus the headline, and the blaring whoopty do.

That article didn't get even the slightest bit real until near the end in the last two paragraphs where the details were hid.

In the very last paragraph we meet Dr. Heck:

"Dr Heck told BBC News: "Only 10% of the grains are older than 5.5 billion years, 60% of the grains are "young" (at) 4.6 to 4.9 billion years old, and the rest are in between the oldest and youngest ones."

There Dr Heck is allowing a glimpse of the real to be seen. In a normal distribution 10% will deviate by about that amount, that's in keeping for the first standard deviation for that kind of dating. That lone 7.5 billion year date is in the second standard deviation, also well within keeping.

The date should read: 4.6 to 4.9 billion years, plus or minus 0.7 billion years.

But heck if he didn't kneed the results a bit after he said, and he did, that headline would have read:

"Exciting science bombshell! Asteroid space rock radioactive ion dated and it's the same age as the Earth!!!

That would be known as a media dud.

Heck!

if our sun burns out does it revert back to no years old?

I think "dust to dust" applies to suns same as it does for living things.

When a sun nova's, much of it's mass is expelled into space, and that part reverts back to being scattered dust, from which has to condense and collect until enough mass comes together to begin the fusion process anew.

Jupiter has almost enough mass gathered together to become a baby star. It's generating some energy now.

Origins of interest: Meteorology

Meteorologists reflect on what triggered their initial interest in weather at the American Meteorological Society's 100th annual meeting in Boston, Massachusetts.

YouTube ran ads for major brands, environmental nonprofits on climate misinformation videos

Greenpeace is not happy that its advertisements were found on YouTube videos featuring climate change denialism and misinformation.

The environmental nonprofit on Thursday called on YouTube to change how it handles content that denies or downplays global warming, pushing the social media giant to pull ads and change its recommendation algorithm.

Like Sam said, exhausted stars usually collapse inward from gravitation and nova, then there is no star. There is dust and gas, which can accrete into various things. (Jupiter might have solid hydrogen.)

Jupiter is fairly close to the mass needed for fusion to begin, though that won't happen any time soon, if ever. It does give out more energy than it gets from the sun, though most is the result of moving mass in magnetic fields. Most of this is RF of various wavelengths.

Several SF stories have postulated Jupiter igniting and turning the sun into a binary star. Talk about lighting up the night, not to mention changing the climate on Mars.

US court dismisses suit by youths over climate change

PORTLAND, Ore. (AP) — A federal appeals court on Friday dismissed a lawsuit by 21 young people who claimed the U.S. government’s climate policies and reliance on fossil fuels harms them, jeopardizes their future and violates their constitutional rights, potentially dealing a fatal blow to a long-running case that activists saw as an important front in the war against environmental degradation.

The Oregon-based youth advocacy group Our Children’s Trust filed the lawsuit in 2015 in Eugene on behalf of the youngsters. It sought an injunction ordering the government to implement a plan to phase out fossil fuel emissions and draw down atmospheric carbon dioxide emission. The case had bounced around the federal courts for five years and multiple trial dates were canceled.

Oh boy

California teachers sue after jetliner dumps fuel on schools

LOS ANGELES (AP) — Four teachers from a Los Angeles-area school sued Delta Air Lines on Friday, saying they were exposed to jet fuel when a plane with engine trouble dumped its fuel over a densely populated area, including several schools, while making an emergency return to the airport.

At a news conference, the teachers described the fuel as drizzling down like raindrops with “overwhelming” fumes. They said their panicked students screamed and cried.

Strong 6.0 earthquake hits Indonesia’s Papua

A strong 6.0 magnitude earthquake shook Indonesia’s easternmost region of Papua on Sunday, the United States Geological Survey said.

There was no tsunami warning accompanying the quake which struck inland 158 kilometres (98 miles) from the provincial capital Jayapura at a shallow depth of almost 34 kilometers, USGS said.

'Snowmageddon': cleanup begins after record Newfoundland storm

Canada’s federal government will help Newfoundland on the Atlantic coast dig itself out in the wake of a massive winter blizzard that buried cars and left thousands without power.

The storm on Friday and Saturday dumped as much as 76.2cm (30 inches) of snow on St John’s, the capital of Newfoundland, and packed wind gusts as high as 130km/h (81mph). The snowfall was an all-time record for the day for St John’s international airport.
