Scientists find origin-of-life molecule in space for first time

Posted by in categories: chemistry, cosmology, particle physics

A molecule common to Earth and usually associated with life has been detected in the depths of space by scientists.

Carbonic acid (HOCOOH), which you may know as the chemical that makes your soda fizzy, was discovered lurking near the center of our galaxy in a galactic center molecular cloud named G+0.693–0.027, a study published in The Astrophysical Journal revealed.

This marks the third time that carboxylic acids—this class of chemicals, often thought to be some of the building blocks of life —have been detected in space, after acetic acid and formic, and the first time that an interstellar molecule has been found to contain three or more oxygen atoms.

Black Hole Theory Finally Explains How Galaxies Form

Posted by in category: cosmology

One clue comes from the observation that most galaxies contain massive black holes at their centers. That has led to the proposal that galaxies form around black holes which act as seeds for this process.

But there is a problem with this idea. If it is true, something must stop stars from falling into black holes as they form, but nobody knows what.

Now a new theory of black holes explains this process. The new theory “gives a general mechanism by which a central black hole can catalyze galaxy formation,” says Stephen Adler, at Princeton University in New Jersey.

Black holes may be hurtling around at 10 per cent the speed of light

Posted by in category: cosmology

When two black holes merge to form a single one, it can zoom off at an extraordinary pace – but scientists have found that it does have a speed limit.

How did supermassive black holes get so big so fast just after the Big Bang?

Posted by in category: cosmology

Finding supermassive black holes with masses billions of times greater than the sun under a billion years after the Big Bang has scientists confused how these cosmic titans got so big so quickly.

Can Cells Think? The Magic of Developmental Biology

Posted by in categories: biological, cosmology, evolution, neuroscience

The John Templeton Foundation recently invited biologist Michael Levin to speak to a small group about the presence of agency and cognition in the most fundamental forms of life, even at the levels of cells and tissues. In the recorded video, Dr. Levin, who directs a developmental biology lab at Tufts University, discusses with Philip Ball, a science writer and author of the newly published Book of Minds: How to Understand Ourselves and Other Beings.

Founded in 1987, the John Templeton Foundation supports research and dialogue on the deepest and most perplexing questions facing humankind. The Foundation funds work on subjects ranging from black holes and evolution to creativity, forgiveness, and free will. It also encourages civil, informed dialogue among scientists, philosophers, theologians, and the public at large.
