Many researchers believe that physics will not be complete until it can explain not just the behaviour of space and time, but where these entities come from. “Imagine waking up one day and realizing that you actually live inside a computer game,” says Mark Van Raamsdonk, describing what sounds like a pitch for a science-fiction film. But for Van Raamsdonk, a physicist at the University of British Columbia in Vancouver, Canada, this scenario is a way to think about reality. If it is true, he says, “everything around us — the whole three-dimensional physical world — is an illusion born from information encoded elsewhere, on a two-dimensional chip”. That would make our Universe, with its three spatial dimensions, a kind of hologram, projected from a substrate that exists only in lower dimensions. This 'holographic principle' is strange even by the usual standards of theoretical physics. But Van Raamsdonk is one of a small band of researchers who think that the usual ideas are not yet strange enough. If nothing else, they say, neither of the two great pillars of modern physics — general relativity, which describes gravity as a curvature of space and time, and quantum mechanics, which governs the atomic realm — gives any account for the existence of space and time. Neither does string theory, which describes elementary threads of energy. Van Raamsdonk and his colleagues are convinced that physics will not be complete until it can explain how space and time emerge from something more fundamental — a project that will require concepts at least as audacious as holography. But, where is the evidence that there actually is anything more fundamental than space and time? A provocative hint comes from a series of startling discoveries made in the early 1970s, when it became clear that quantum mechanics and gravity were intimately intertwined with thermodynamics, the science of heat. In 1974, most famously, Stephen Hawking of the University of Cambridge, UK, showed that quantum effects in the space around a black hole will cause it to spew out radiation as if it was hot. Other physicists quickly determined that this phenomenon was quite general. Even in completely empty space, they found, an astronaut undergoing acceleration would perceive that he or she was surrounded by a heat bath. The effect would be too small to be perceptible for any acceleration achievable by rockets, but it seemed to be fundamental. If quantum theory and general relativity are correct — and both have been abundantly corroborated by experiment — then the existence of Hawking radiation seemed inescapable. A second key discovery was closely related. In standard thermodynamics, an object can radiate heat only by decreasing its entropy, a measure of the number of quantum states inside it. And so it is with black holes: even before Hawking's 1974 paper, Jacob Bekenstein, now at the Hebrew University of Jerusalem, had shown that black holes possess entropy. But there was a difference. In most objects, the entropy is proportional to the number of atoms the object contains, and thus to its volume. But a black hole's entropy turned out to be proportional to the surface area of its event horizon — the boundary out of which not even light can escape. It was as if that surface somehow encoded information about what was inside, just as a two-dimensional hologram encodes a three-dimensional image. In 1995 then, Ted Jacobson, a physicist at the University of Maryland in College Park, combined these two findings, and postulated that every point in space lies on a tiny 'black-hole horizon' that also obeys the entropy–area relationship. From that, he found, the mathematics yielded Einstein's equations of general relativity — but using only thermodynamic concepts, not the idea of bending space-time. Ted's result suggested that gravity is statistical, a macroscopic approximation to the unseen constituents of space and time. In 2010, this idea was taken a step further by Erik Verlinde, a string theorist at the University of Amsterdam, who showed that the statistical thermodynamics of the space-time constituents — whatever they turned out to be — could automatically generate Newton's law of gravitational attraction. In separate work, Thanu Padmanabhan, a cosmologist at the Inter-University Centre for Astronomy and Astrophysics in Pune, India, showed that Einstein's equations can be rewritten in a form that makes them identical to the laws of thermodynamics — as can many alternative theories of gravity. Padmanabhan is currently extending the thermodynamic approach in an effort to explain the origin and magnitude of dark energy: a mysterious cosmic force that is accelerating the Universe's expansion.

A set of printable storytelling prompts for kids. Prompt your child's imagination with this set of creative storytelling & writing prompts.
Layer upon layer, but they are slowly being peeled away-can't wait to see brown cork! Oh geez, May is busy. Blogging has taken a back seat, far far in the back. And the more I get behind the more I feel like "why catch up?" and then I just decide to not even try. I hope everyone had a nice Mother's Day-it was beautiful here, and busy, and it was just like every other day. We went to church, even though Abbey came a little late because she had a very early ACT class, it was SO nice to have everyone together in one pew. That was what I really wanted more than anything for Mother's Day! In the news: Poor Andrew is on the mend from a broken wrist-we bought a slack line for the kids this Christmas, and it was so fun-until this injury. This puts a damper on the beginning swim team practices and he is very disappointed. Patrick lost another tooth in a soccer incident. He wrote a cute note to the tooth fairy, telling her to please leave his tooth, he wanted it as a souvenir. I am SO enjoying sending boys outside to play though, injuries or not! We are doing a house addition/renovation. We have thought about doing this for years and years and finally decided last fall to go for it. I love our neighborhood, I love our neighbors, I love our house, I love our yard. I want my grand kids coming to visit me here one day in the future, so we decided moving was out of the question. And Abbey said it best, "If we move, I'll leave for college and I will have to come back to a house that never even felt like home." I wish I could say it was fun and exciting but I just want to pretend the extra space all magically appeared one day. No endless decisions (I know some people think this is fun, I don't), no hassle, no inconvenience, no worry, no pounding, no strangers in your house all day-that is what I look forward to. Six more weeks. They promised. I remind the contractors of that every single day. I can't wait till it's all over! Here is the best thing I ever found on Pinterest by the way: Isn't that true? The stars make me feel small and make what's most important in life stand out. Usually I find the time to gaze at them for about 60 seconds between parking the car and walking in the house after picking some milk up at the grocery store, but that 60 seconds makes all the difference in the world. May Crowning was so beautiful. So is this little girl. She is getting too big though isn't she? But I have the whole summer to say she is just one. And her legs still have chubby rolls. Isaac is home from college. Some good books I've read lately: This is excellent. If you have a pre-teen or teenage girl, this book is so informative about the real struggles are girls are facing with our crazy culture today. I ordered Dr. Sax's other two books right after I finished this one. I think this book should be a textbook for a mandatory class in high school. It's really really good. I loved this book! Honestly, I could not put this book down-well I had to of course, but the whole time I wasn't reading it, I was waiting till I had a chance to sneak away and pick it up again. If I could have put toothpicks in my eyelids at night to keep reading I would have. I hid in the bathroom for a few minutes to finish a chapter. It was so so good. I wanted to attempt this book but my May brain won't let me right now. I'm going to save it for later-like September later.
