Einstein called the entanglement phenomenon spooky at a distance.

If you like quantum entanglement and are unfamiliar with all the delayed choice quantum eraser experiments, this video can be mind blowing:

As mind blowing as the quantum eraser experiment is...if you sit around long enough thinking about it...you'd probably come up with a theory of how it works. In fact lots of people have come to essentially the same theory...some type of pilot wave (ghost waves, per Einstein)...Bohmian mechanics. It's cool that everyday people are figuring this stuff out that physicists spent lifetimes not conceptualizing/recognizing (e.g. making a white hole in your sink), or diving "fist bubbles" is really what goes on (on a much larger scale and visually the opposite of) with quantum fluctuations (and/or what happens at CERN). The math of all this stuff is crazy...but visually there's not left to the imagination...cavitations upon cavitations...like the Mandelbrot sets.

If you conceptualize a long bubble under water...with one water molecule "a" on one end of the bubble partnered to a water molecule "z" way at the other end of the bubble...then popping the bubble next to "a" can cause "z" to move without per se involving a molecule to molecule interaction (i.e. classical mechanics) between "b, c, d...w,x,y." Simply the bubble collapsing causes everyone to move, even if they don't know why...and this must occur forward/backwards in space-time...as the quantum eraser experiment shows. All this said, Sagan said something to the effect that we are just the universe describing itself...the referenced news article puts an interesting twist on this.

You can search the first 200 million digits of pi at the Pi Search website, maintained by David Andersen, a professor of computer science at Carnegie Mellon University in Pittsburgh.

In 2016, a Swiss scientist, Peter Trueb, used a computer with 24 hard drives and a program called y-cruncher to calculate pi to more than 22 trillion digits, the current world record for the enumeration of pi. If you read one digit every second, it would take you just under 700,000 years to recite all those digits.

Just gone to 31.4 trillion digits

Still doesn't match a good anchoring thread on CF

I can hardly imagine the size of the file to store that much data.

Tragedy in Christchurch
At least 49 people were killed and 20 seriously injured in two mass shootings at mosques in the New Zealand city of Christchurch.
Forty-one people were killed at the al Noor mosque.
Seven people died at the Linwood mosque, and one person died from their injuries in hospital.
On behalf of cruisers worldwide, we offer our deepest condolences, and a message of solidarity and peace, to the people of New Zealand, at this tragic time.

That would be about 31.4 Terabytes for a plain ASCII text file.



With external 2TB drives readily available for 50 bucks or so, it's feasible for anyone to have a copy . The problem would be how long it takes to download the data from Google's cloud

“The World Wide Web Turns 30. Where Does It Go From Here?” ~ Tim Berners-Lee
On the World Wide Web’s 30th birthday, our founder and web inventor Sir Tim Berners-Lee reflects on how the web has changed our world and what we must do to build a better web that serves all of humanity.
"Today (03.11.19), 30 years on from my original proposal* for an information management system, half the world is online. It’s a moment to celebrate how far we’ve come, but also an opportunity to reflect on how far we have yet to go..."

*In March 1989, Tim Berners-Lee submitted a proposal for an information management system to his boss, Mike Sendall. ‘Vague, but exciting’, were the words that Sendall wrote on the proposal.

“The Rapid Decline Of The Natural World Is A Crisis Even Bigger Than Climate Change” ~ by John Vidal
A study from the Intergovernmental Science-Policy Platform On Biodiversity and Ecosystem Services (IPBES), expected to run to over 8,000 pages, is being compiled by more than 500 experts in 50 countries. It is the greatest attempt yet to assess the state of life on Earth, and will show how tens of thousands of species are at high risk of extinction, how countries are using nature at a rate that far exceeds its ability to renew itself, and how nature’s ability to contribute food and fresh water to a growing human population is being compromised in every region on earth.
Although their conclusions are stark, the IPBES authors are not entirely gloomy about Earth’s prospects. In offering practical options for future action, they want to show that it is not too late to slow down or even reverse degradation.
The authors are expected to say in their conclusions that to avoid disaster, existing laws will have to be enforced, and further regulations put on, for example, deforestation and overfishing. Reports already published have also called for better protection of pollinators, tighter control of invasive species and greater public awareness of the decline in nature.
They will also recognize that individual and community actions to plant trees, regenerate abandoned lands and protect nature can have a major positive impact.

> Intergovernmental Science


Another oxymoron?

Yep, no predetermined study results there

Don’t be disingenuous.
The IPBES release was an "Information Alert".

The report was 3 years in the making, and is virtually complete, but not yet publicly presented, in full.
The report will be finalized and considered at the seventh session of the IPBES Plenary (#IPBES7, 29 April –4 May 2019).
A detailed ‘Summary for Policy Makers’ of the report, highlighting key messages, findings and options is scheduled for public launch at UNESCO world headquarters, Paris,Monday, 6 May 2019, to be webcast live (available at www.ipbes.net) at 15:00 CEDT (09:00 US EDT/13:00 GMT–check for other times worldwide here: http://bit.ly/2zUiyL7).

“No, scientists didn’t just “reverse time” with a quantum computer” ~ by Konstantin Kakaes
If you believe what you read on the internet, it’s been an exciting 24 hours for quantum physics.
The headlines have been incredible. Newsweek (Scientists Have Reversed Time in a Quantum Computer), Discover (Scientists Used IBM’s Quantum Computer to Reverse Time, Possibly Breaking a Law of Physics) and the UK’s Independent newspaper (Scientists ‘Reverse Time’ With Quantum Computer in Breakthrough Study). Cosmopolitan magazine also chimed in: Scientists just turned back time and it’s like Back to the Future is coming true. There are many, many more.
The trigger for all of these was a Scientific Reports paper with the provocative title “Arrow of time and its reversal on the IBM quantum computer.” In it, the authors claimed to have performed an experiment that opens up lines of research, in their words, toward “investigating time reversal and the backward time flow.”
If you had difficulty understanding how scientists accomplished such a counterintuitive feat, don’t worry. They didn’t.
