- The number of Muslims will nearly equal the number of Christians around the world.
- Atheists, agnostics and other people who do not affiliate with any religion – though increasing in countries such as the United States and France – will make up a declining share of the world’s total population.
- The global Buddhist population will be about the same size it was in 2010, while the Hindu and Jewish populations will be larger than they are today.
- In Europe, Muslims will make up 10% of the overall population.
- India will retain a Hindu majority but also will have the largest Muslim population of any country in the world, surpassing Indonesia.
- In the United States, Christians will decline from more than three-quarters of the population in 2010 to two-thirds in 2050, and Judaism will no longer be the largest non-Christian religion. Muslims will be more numerous in the U.S. than people who identify as Jewish on the basis of religion.
- Four out of every 10 Christians in the world will live in sub-Saharan Africa." (source)

The Future of World Religions
"The religious profile of the world is rapidly changing, driven primarily by differences in fertility rates and the size of youth populations among the world’s major religions, as well as by people switching faiths. Over the next four decades, Christians will remain the largest religious group, but Islam will grow faster than any other major religion. If current trends continue, by 2050 …

Genetics of Earth and Moon
"The giant impact theory echoes what we know about the formation of the entire Solar System, which coalesced from a disk of gas and dust around the young Sun. The Earth and the other planets grew in a series of collisions, starting from dust particles and culminating in massive impacts between planet-sized bodies. The last giant impact involving the growing Earth may have spawned the Moon by creating a disk of rocky debris in orbit around the planet. The giant impact model has become so popular that the two bodies involved in the impact even have names: the proto-Earth (the progenitor of Earth) and Theia (the impacting body, named for the Greek goddess who was the mother of the Moon)....
In the giant impact theory, the proto-Earth and Theia are generally assumed to have had different oxygen isotope signatures. That’s because each planet’s signature is determined by its orbit; presumably, the only way to get nearly identical signatures is for two planets to form on nearly the same orbit, which does not fit with how we think planets grow. So if Earth and Theia had different fingerprints, why do the Earth and Moon share the same one?" (source)

The Unaware
“In the extreme case, it may be that whenever a software developer in Menlo Park adjusts a parameter, someone somewhere wrongly starts to believe themselves to be unloved,” wrote a team of researchers led by University of Illinois at Urbana-Champaign doctoral student Motahhare Eslami, in a new paper on Facebook’s news feed algorithm.
The new qualitative research study sampled 40 Facebook users and ran them through an in-depth examination of the ways that Facebook filters their experience. Twenty-five of the users—or more than 60 percent — had no idea that there even was a filtering algorithm, let alone one that looks at more than a thousand data signals to determine what to show a user. The researchers termed these innocent users “the unaware.” (source)
