Ancient stars found in the outer reaches of our Milky Way are surprisingly chock full of some of the heaviest chemical elements, which could have formed in the galaxy's early history, a new study reveals.

Were there any "laws of the universe" at the time of the "big bang?" Oxford trained biologist Rupert Sheldrake, Ph.D., author of The Presence of the Past, says that all laws developed as "habits" over time. Thus the universe and its laws can be seen to be continually evolving. In this view the theory of evolution can be applied to physics, chemistry and cosmology.

(PhysOrg.com) -- Astronomers at the Max Planck Institute for Astronomy have, for the first time, measured the alignment of magnetic fields in gigantic clouds of gas and dust in a distant galaxy.

It's obvious that time has a direction: you were younger a decade ago than you are today. But according to the laws of physics, there is no intrinsic difference between the past and the future. In our latest One-Minute Physics animation, guest narrator Sean Carroll, a physicist at the California Institute of Technology in Pasadena, explains why a better understanding of the big bang will help explain the arrow of time.

Some time ago, I interviewed Weinberg about his work and the anthropic principle, which led him to this striking prediction. “The universe,” he told me, “could well be like a giant Schrödinger’s Cat. There are parts of the universe where the cat is alive, where the cosmological constant is just the right level and there are scientists there observing it and asking questions. And there are parts of the universe where the cat is dead—where the cosmological constant is too small or too large and therefore there is no life and no scientists asking questions about the universe.” To me, this image of the giant cat is the best analogy for a universe governed by the powerful, and yet perhaps disturbing, idea of the anthropic principle.

The world as it is viewed from modern physics and cosmology has many strange and unexpected features. Often these are in stark contrast to our everyday experience or our preconceptions, such as the concept of space and time as finite and changeable.

The parable of the blind men and elephant is a perfect metaphor for the universe and for the physicists who try to grasp its larger shape: each man feels a part of the elephant and tries to visualize its overall essence: "It's a wall"; "It's a rope"; "a tree": they almost come to blows. The universe, even more than the elephant, is too big for any one perspective, and most of us are busy squabbling about some small part.

I tend to agree, in spirit, with Isaac Asimov when he wrote, “I believe that scientific knowledge has fractal properties, that no matter how much we learn, whatever is left, however small it may seem, is just an infinitely complex as the whole was to start with. That, I think, is the secret of the Universe.” In fact, our brains, which evolved to make us run from lions on the African savanna, may not be constructed to penetrate the infinite veil of reality. We may need mathematics, physics, computers, brain augmentation, and even literature, art, and poetry to help us tear away the veils. For those of your readers who are about to embark on reading The Physics Book from cover to cover, look for the connections, gaze in awe at the evolution of ideas, and sail on the shoreless sea of imagination.

My inaugural column for Discover discussed the lighting-rod topic of the inflationary multiverse. But there’s only so much you can cover in 1500 words, and there are a number of foundational issues regarding inflation that are keeping cosmologists up at night these days. We have a guest post or two coming up that will highlight some of these issues, so I thought it would be useful to lay a little groundwork. (Post title paraphrased from Andrei Linde.)
