  Dwayne ‘The Rock’ Johnson announces XFL to return for 2022 season Dwayne ‘The Rock’ Johnson was part of an ownership group that purchased the XFL back in early August, and now he is announcing that the top spring football league plans to return for a 2022 season. © Sarah Stier-USA TODAY Sports Johnson, who co-owns the league with RedBird Capital Partners and business partner Dany Garcia, bought the XFL in August for $15 million. Once the sale was approved, the team started working on plans to relaunch the popular football league.Even before Johnson helped buy the XFL, there was always hope the spring football league would return within two years.

Intelligent Life Really Can ' t Exist Anywhere Else . Hell, our own evolution on Earth was pure luck. Life has come a very long way in a very short time on Earth, relatively speaking—and scientists say that represents even more improbable luck for intelligent life that is rare to begin with.

Life and intelligent life may be so rare in our microscopic time scale that it never exists in more than one place at the same time and there may be Really , any politician gonna put their name on an expensive endeavor like that and expect t . Does intelligent life exist in the galaxy or the universe?

  • Cosmic statisticians say the likelihood of life evolving on Earth is even less than we thought.
  • Analysis suggests individual steps in evolution were more likely to take longer than Earth's existence.
  • The scientists say this research is designed give future researchers a foundation.

In newly published research from Oxford University's Future of Humanity Institute, scientists study the likelihood of key times for evolution of life on Earth and conclude that it would be virtually impossible for that life to evolve the same way somewhere else.

Browns keeping fingers crossed about Nick Chubb’s knee injury

  Browns keeping fingers crossed about Nick Chubb’s knee injury He’ll have an MRI on Monday to tell the full story, but it looks like he isn’t going to be done for the year. © Ken Blaze-USA TODAY Sports Despite losing Nick Chubb to injury, the Browns still beat the Cowboys on Sunday. Chubb wasn’t the only one to go down with a knee injury in the same game. Cowboys center Joe Looney also hurt his knee and was quickly ruled out, which had Dallas fans holding their breath. Like with Chubb however, it appears it could’ve been worse, as Michael Gehlken of the Dallas Morning News tweets that there’s “hope the injury is not of season-ending variety.

Also, due to the vastness of the universe, intelligent life is likely to exist . Another reason one may be likely to believe that intelligent life exists elsewhere is because a distress signal from the M33 galaxy was heard as well as radio transmissions going back and forth.

4. If intelligent life is prolific, why haven' t superior aliens broadcast their existence from all corners of the universe, and why haven' t they been received by Earth as messages across space? There are many more arguments against there being intelligent aliens, and perhaps some even better ones for.

Life has come a very long way in a very short time on Earth, relatively speaking—and scientists say that represents even more improbable luck for intelligent life that is rare to begin with.

For decades, scientists and even philosophers have chased many explanations for the Fermi paradox. How, in an infinitely big universe, can we be the only intelligent life we’ve ever encountered? Even on Earth itself, they wonder, how are we the only species that ever has evolved advanced intelligence?

There are countless naturally occurring, but extremely lucky ways in which Earth is special, sheltered, protected, and encouraged to have evolved life. And some key moments of emerging life seem much more likely than others, based on what really did happen.

'Pieces of a Woman' is a gripping drama about grief that delivers an astounding performance by Vanessa Kirby

  'Pieces of a Woman' is a gripping drama about grief that delivers an astounding performance by Vanessa Kirby The movie has the feel of a 1970s drama with its incredible ensemble cast and tender story about loss.That's a testament not just to director Kornél Mundruczó and writer Kata Wéber but also the perfect cast that includes Shia LaBeouf, Sarah Snook, Benny Safdie, Molly Parker, Benny Safdie, and the legendary Ellen Burstyn.

Some kind of life is probably present on hundreds of millions or billions of planets in our galaxy alone, and there are at least 50 billion galaxies of comparable size in the observable Universe, so there should be a virtually unimaginable number

We've been searching for intelligent life in the universe for decades, but have we been doing it all wrong? _ DNews is dedicated to satisfying your curiosity and to bringing you mind-bending stories & perspectives you won' t find anywhere else !

“The fact that eukaryotic life took over a billion years to emerge from prokaryotic precursors suggests it is a far less probable event than the development of multicellular life, which is thought to have originated independently over 40 times,” the researchers explain. They continue:

“The early emergence of abiogenesis is one example that is frequently cited as evidence that simple life must be fairly common throughout the Universe. By using the timing of evolutionary transitions to estimate the rates of transition, we can derive information about the likelihood of a given transition even if it occurred only once in Earth's history.”

In this paper, researchers from Oxford University’s illustrious Future of Humanity Institute continue to wonder how all this can be and what it means. The researchers include mathematical ecologists, who do a kind of forensic mathematics of Earth’s history.

San Francisco curbs virus but once-vibrant downtown is empty

  San Francisco curbs virus but once-vibrant downtown is empty SAN FRANCISCO (AP) — San Francisco is reopening more businesses this week, thanks to low coronavirus case numbers that have allowed the city to move into California's most permissive tier. It means more people can go back to offices, dine indoors and visit museums. But businesses and those residents who haven't joined an exodus out of the city are wondering when san Francisco's once-vibrant economy may bounce back.

Its possible that other life exist outside of Earth. The question is are they intelligent enough to emit Radio signals? Radio waves travel at the speed of Nothing to indicate anywhere in the universe that this happened, ever. Except for happening here. Another striking against it is that it didn' t happen the

And if life exists in another galaxy? After all most of the claims of visitation are for beings from other realms or galaxies. So if you're right, and the universe is just crawling with all kinds of intelligent life , you need to come up with all kinds of non-mathematical reasons to explain why we can ' t just look up

In this case, they’ve used a Bayesian model of factors related to evolutionary transitions, which are the key points where life on Earth has turned from ooze to eukaryotes, for example, and from fission and other asexual reproduction to sexual reproduction, which greatly accelerates the rate of mutation and development of species by mixing DNA as a matter of course.

Most of these “evolutionary transitions” are poorly understood and have not been very well studied by the scientists of likelihoods. And using their model, these scientists say that Earth’s series of Goldilocks lottery tickets are more likely to have taken far longer than they really did on Earth.

From this age on people don't get any more intelligent - say researchers

 From this age on people don't get any more intelligent - say researchers It would take a lot of time to look at all the chess games that an international research team has just evaluated for a new study. The scientists analyzed 24,000 professional games, consisting of around 1.6 million moves that chess professionals made between 1890 and 2014.

There’s an iconic scene in the 2001 movie Ocean’s Eleven where George Clooney explains the series of escalating improbabilities of his planned crime. After several hugely unlikely outcomes, he says, “Then it's a piece of cake: just three more guards with Uzis, and the most elaborate vault door conceived by man.” In a way, the unlikely hurdles to the rapid flourishing of complex life on Earth are the same way.

First, we win the lottery for surface temperature and protection from spaceborne dangers. Second, we win the lottery for the presence of building blocks of life. Third, we win the lottery for the right location for the right building blocks. That’s before anything like the most primitive single cell has even emerged.

Using some information we do know, like the age of Earth and the expected end of its habitable lifetime due to the expanding heat radius of our sun, these researchers have turned evolutionary transitions into a series of existential scratch-off tickets. Read the whole fascinating study here.
