This is the strangest science story I've read in a long time. Looks like a pebble found in Egypt is older than the Sun:

It can't be, Jack. Everyone knows that the whole universe was created by the big man upstairs 3 million years ago...

:D tG

This'd be a cool thread title for above the line, so we could list the most bonkers rock bands...

I think there is a word of caution in the opening paragraph. It says the micro-minerals compounds were NOT KNOWN to occur on Earth, meteor, comet etc.

That is not the same as saying they DO NOT occur on Earth, meteor, comet etc.

Given the infinite nature of the Universe this sample could have been part of a meteor or comet that as yet, we mere humans, have not chanced upon before.

That our knowledge of the Universe is at best limited all manner of chemical combinations of may be present elsewhere in the Universe of which we have no knowledge.

It seems reasonable to me that this kind of deep space debris coalesced from old second or third generation star explosions that made these elements like pure aluminum. This kind of stuff could have made it to our Oort cloud region easily before our sun ignited. Our solar system has a magnetic barrier and solar wind now that makes it harder for deep space debris to get all the way in to an Earth crossing orbit.

Einstein was firm about The Universe being similar to itself anywhere in the Universe. However there are regions of our observable universe (1/50th of 1 %) that are not similar to the rest of the universe. That is still a huge region. That is big enough to require a larger sample size to show the homogeniousity of our universe Albert spoke of.
It is also big enough to allow some exceptions to the rules/laws.

What is this mystery .02 % of the universe? It is a super mega group of galaxies that is too big to exist by our laws and consists mostly of galaxies that still have quasars instead of dark black holes.


There at lots of mysteries out there like the star that is only 20 light years away that has been around for 13 billion years*!!!

*13 billion years + or - 700 million years

PFR, I was thinking more of genres. Such as doom-sludge-death-psyche-harpsichord. Too many hyphens these days.

A fruitcake, huh?
Humanity: doomed to dream of asking questions knowing we'll never live long enough to find answers. I wonder how someone discovered that pebble and thought to test it.

I always fancied something like Liberace plays Led Zeppelin but was never quite sure where to get it...

It's bound to be on youtube...

Or something close like "Lieutenant Pigeon play Led Zep in the style of Liberace..."

Liberace knew where to get it.

I think I would like to see more research on this topic. Argument still occurs over the origin of the desert glass found in the same area.

There is plenty of evidence* to indicate a meteor or asteroid strike to end the Iains implied 'argument' by the ancient alien theorists who claim there was a nuclear war 'back in the day'. Who knows maybe that pebble is part of the Ka'aba stone.


* written Egyptian accounts of a ball of fire from the heavens. desert glass is made by impacts. Here in Maryland the impact that made the Chesapeake Bay is evidenced by shocked quartz boulders debris everywhere. They are brilliant white with minute dark veins. It is what we all use for landscaping here.

Dave I googled it but only came up with stuff like (Liver a' chi with walnuts) and (Heavy metals in Liberal Aussie.)

Aliens??????
Are you away with the faerys Donuel????

As Wikipedia succinctly states:
"The origin of Desert glass is uncertain. Meteoritic origins have long been considered possible, and recent research links the glass to impact features, such as zircon-breakdown, vaporized quartz and meteoritic metals, and to an impact crater. Some geologists associate the glass with radiative melting from meteoric large aerial bursts, making it analogous to trinitite created from sand exposed to the thermal radiation of a nuclear explosion."

Now the "argument" is no longer implied. Thank you.

Speaking of impacts, with exception of the impact that created our moon, the second largest impact in Antarctica is now covered by ice and may have been respondsible for the wobble and axis tilt that produced the change of seasons.

Thanks for the interesting article, Jack.
