Without nuclear power, the world’s climate challenge will get a whole lot harder

The Covid-19 crisis not only delivered an unprecedented shock to the world economy. It also underscored the scale of the climate challenge we face: Even in the current deep recession, global carbon emissions remain unsustainable.

If the world is to meet energy security and climate goals, clean energy must be at the core of post-Covid-19 economic recovery efforts. Strong growth in wind and solar energy and in the use of electric cars gives us grounds for hope, as does the promise of emerging technologies like hydrogen and carbon capture. But the scale of the challenge means we cannot afford to exclude any

Gravity As Matter Warping Space-Time Now 500 Times Harder To Disprove

KEY POINTS

  • Many experts cast doubts on Einstein’s theory for more than a century
  • A new study proved Einstein’s theory of relativity aligns with present-day quantum physics
  • The conclusion was based on the first photo of a supermassive black hole

Albert Einstein’s theory of relativity becomes 500 times harder to negate as the first image ever taken of supermassive blackholes made a stronger case that gravity, indeed, is a matter warping spacetime. The photo of the black hole’s shadow was consistent with astrophysical findings of the much later time, therefore giving significant weight to Einstein’s idea of general relativity. 

Einstein’s theory that gravity is caused by a warping spacetime has been under the scientific lens for more than 100 years. Many experts of modern times have cast their doubts on his finding, saying that it remains mathematically irreconcilable with the foundation of quantum mechanics. 

In general, quantum physicists assert that

Einstein’s description of gravity just got much harder to beat — ScienceDaily

Einstein’s theory of general relativity — the idea that gravity is matter warping spacetime — has withstood over 100 years of scrutiny and testing, including the newest test from the Event Horizon Telescope collaboration, published today in the latest issue of Physical Review Letters.

According to the findings, Einstein’s theory just got 500 times harder to beat.

Despite its successes, Einstein’s robust theory remains mathematically irreconcilable with quantum mechanics, the scientific understanding of the subatomic world. Testing general relativity is important because the ultimate theory of the universe must encompass both gravity and quantum mechanics.

“We expect a complete theory of gravity to be different from general relativity, but there are many ways one can modify it. We found that whatever the correct theory is, it can’t be significantly different from general relativity when it comes to black holes. We really squeezed down the space of possible modifications,” said

Facebook’s latest integrations with Instagram could make it harder for regulators to break up the company

Today, let’s talk about a couple little things that could turn into a big thing.

In January 2019, Mike Isaac reported a noteworthy development about Facebook at the New York Times. In the months to come, he said, Facebook would unify the technical infrastructure powering Facebook, Instagram, and WhatsApp. To the user, these changes would be invisible. But to Facebook itself, there were clear strategic imperatives to merge the apps. Among them: the move came just as the US government was beginning to consider an effort to break the company up.

In the nearly two years since, the government’s effort has accelerated. On September 15th, the Wall Street Journal reported that an antitrust case against the company could come by the end of the year. But Facebook’s effort to puree its family of apps into a single software smoothie on the back end has picked up as well. And
