Fwd: Asteroids and earth life


Asteroid dust may have triggered massive explosion of life on Earth 466 million years ago

Nearly half a billion years ago, there was a huge explosion of species development on Earth, causing the biodiversity of animals to increase dramatically -- but the true cause of that event has remained a mystery.

In a new paper published on Wednesday in Science Advances, scientists show that the event's onset coincided with the largest documented asteroid breakup in the asteroid belt over the past two billion years.

That breakup, which was triggered by a collision with another asteroid or comet, would have spread enormous amounts of dust throughout the solar system.

"The blocking effect of this dust could have partly stopped sunlight from reaching the Earth – leading to cooler temperatures," the study's co-author Birger Schmitz, a professor of nuclear physics at Lund University, writes in The Conversation. "We know that this involved the climate changing from being more or less homogeneous to becoming divided into climate zones – from Arctic conditions at the poles to tropical conditions at the equator. The high diversity among invertebrates, including green algae, primitive fish, cephalopods and corals, came as an adaptation to the new climate."

Schmitz and his colleagues also studied the distribution of very fine-grained, extremely tiny dust in the sediment, determining its extraterrestrial origin by discovering helium and other substances inside the sediments.

"Our results clearly show that enormous amounts of fine-grained dust reached Earth shortly after the breakup," writes Schmitz.

Fwd: Finally a step towards ending border insanity

The U.S. Supreme Court late Wednesday gave the Trump administration permission to enforce its toughest restriction yet on asylum seekers at the southern border

As a result, the government can now refuse to consider a request for asylum from anyone who failed to apply for it in another country after leaving home but before coming here. The order means, for instance, that migrants from Honduras, Guatemala, and El Salvador cannot seek asylum in the U.S. if they didn't first ask for it in Mexico.

Inside 9/11 Zero Hour

National Geographic made a great documentary about the 9/11 attacks called "Inside 9/11 Zero Hour." I made an effort to watch this on youtube every year on September 11, just because I thought it was important to not forget.

The video I used to watch on youtube doesn't seem to be there anymore. There is still video available, but the video quality is not great.

Bill Maher on David Koch's Death: 'I Hope The End Was Painful'

"He and his brother have done more than anybody to fund climate science deniers for decades, so f—him. The Amazon is burning up. I'm glad he's dead, and I hope the end was painful," Maher said.

It is a myth that the Amazon rain forest produces the world's oxygen.  Whenever plants are consumed, whether that be by animals or by bacteria due to decay, it takes an equal amount of oxygen to metabolize the plants.

What Will We Miss?

This is a very interesting video.

https://www.youtube.com/watch?v=7uiv6tKtoKg

It would seem impossible for humans to survive billions of year.  If we have any descendants billions of years from now, then they would be dramatically different in form and function.  They would also have to survive many worldwide extinction events.

Due to plate tectonics coming to an end, the Earth is predicted to be cold, dry and dead in 500 million years.  Maybe our more advanced descendants, if they are still around, will find a way to terraform the planet  

I think that machine intelligence will eventually replace biological intelligence.  I see this happening through our own actions as we slowly modify ourselves.  I think that the beginnings of this will start in our lifetimes.

Here is another very interesting video from the same source, called "Last Words."  https://www.youtube.com/watch?v=Qig68IuPrbk

Patrick Moore - The Power of Truth

I have seen many videos covering anthropogenic global warming, but this is by far the best one.  Patrick Moore says everything I have been saying for years and then some.  He does a better job of documenting and graphing the relevant information.

From Alberta's 6th annual "Freedom School" conference, on "Things that Matter: An Agenda for Alberta".


The first 14 minutes are about his background.  Then he talks about various environmental issues and finally starts a one hour talk about Climate Change 24 minutes into the video.

Samsung Galaxy A20 Review - Amazing Budget Android Phone $160-$200

Budget phones have gotten pretty powerful.  The CPU benchmark on this phone rivals my old desktop computer. When it comes to bencmarks, Apple is usually on top with their own custom CPU's, but Apple seems to want to soak their customers.  I think that I would be quite happy with this budget phone, which is plenty powerful.
