Brief Answers to Cosmic Questions
Structure of the Universe Does the Universe have an edge, beyond which there is nothing? Are the galaxies arranged on the surface of a sphere? Why can't we see the whole universe? Does the term "universe" refer to space, or to the matter in it, or to both? Evolution of the Universe Did the Universe expand from a point? If so, doesn't the universe have to have an edge? More about the Big Bang When they say "the universe is expanding," what exactly is expanding? Structure of the Universe Does the Universe have an edge, beyond which there is nothing? Are the galaxies arranged on the surface of a sphere? Why can't we see the whole universe? If you could suddenly freeze time everywhere in the universe, and magically survey all of creation, you would find galaxies extending out far beyond what we can see today. Does the term "universe" refer to space, or to the matter in it, or to both? Today, the situation is reversed. Evolution of the Universe Did the Universe expand from a point?

Science links Skip to Content Home » Science links Science links The Measurement of Science Albert Einstein’s greatest scientific “blunder” (his word) came as a sequel to his greatest scientific achievement. That achievement was his theory of gravity, the general theory of relativity, which he introduced in 1915. Two years later, in 1917, Einstein ran into a problem while trying to apply general relativity to the Universe as a whole. At the time, Einstein believed that on large scales the Universe is static and unchanging. But he realized that general relativity predicts that such a Universe can’t exist: it would spontaneously collapse in on itself.

Bad Astronomy Well now, this is an interesting discovery: astronomers have found what looks like a "super-Earth" – a planet more massive than Earth but still smaller than a gas giant – orbiting a nearby star at the right distance to have liquid water on it! Given that, it might – might – be Earthlike. This is pretty cool news. We’ve found planets like this before, but not very many! 10 COSAS SOBRE EL UNIVERSO Space The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ?273.15°C, where the motion of all particles stops completely. However, you can never actually cool something to this temperature because, in quantum mechanics, every particle has a minimum energy, called “zero-point energy,” which you cannot get below.

40 technologies to watch in 2011 If the popular misreading of Mayan mythology is correct, we have fewer than two more years left on this Earth. That leaves precious little time for the tech industry to develop and perfect of all the cool technologies that sci-fi authors have dreamed up over the years. Still, while a December 2012 apocalypse may spell doom for the commercial viability of hovercars, it doesn't mean that the next couple of years in tech will be dull — quite the contrary. 2011 is already shaping up to be a banner year for tech and web innovation. Below is a list of over 40 websites, apps, companies, gadgets and technologies that the editors of Mashable think that you should keep an eye on over the coming year. Center for African American Studies We thank the supportive and generous Princeton University alumni who recognize the important work of the Center for African American Studies. On March 11, we dedicated the Hobson-Rogers Seminar Room and the Barfield-Johnson Seminar Room of Stanhope Hall, our historic home. Professor Naomi Murakawa joins the faculty at the Center for African American Studies as an associate professor of African American Studies. AAS 353/ENG 352 (LA) African American Literature: Origins to 1910 Fulfills AAS certificate core survey pre-20th century course requirement Lecture L01: 11:00 am – 11:50 am TTh Christopher M. Brown This introductory required core survey course focuses on texts from the mid-eighteenth century through the early 20th century.

s WMAP Science Team Awarded 2012 Gruber Cosmology Prize NASA's WMAP Science Team Awarded 2012 Gruber Cosmology Prize NASA's Wilkinson Microwave Anisotropy Probe, known as WMAP, transformed the science of cosmology by establishing the age, geometry, and contents of the universe to astonishing precision. On June 20, the Gruber Foundation recognized this accomplishment by awarding its 2012 Cosmology Prize to WMAP principal investigator Charles L. Bennett at Johns Hopkins University in Baltimore and the science team he led. The Shapes of CSS Learn Development at Frontend Masters CSS is capable of making all sorts of shapes. Squares and rectangles are easy, as they are the natural shapes of the web. Add a width and height and you have the exact size rectangle you need. Add border-radius and you can round that shape, and enough of it you can turn those rectangles into circles and ovals. We also get the ::before and ::after pseudo elements in CSS, which give us the potential of two more shapes we can add to the original element.

The end of the net as we know it Posted on 21 Jan 2011 at 13:34 ISPs are threatening to cripple websites that don't pay them first. Barry Collins fears a disastrous end to net neutrality You flip open your laptop, click on the BBC iPlayer bookmark and press Play on the latest episode of QI. But instead of that tedious, plinky-plonky theme tune droning out of your laptop’s speakers, you’re left staring at the whirring, circular icon as the video buffers and buffers and buffers... That’s odd. Global Consciousness Project The Global Consciousness Project (GCP, also called the EGG Project) is a parapsychology experiment begun in 1998 as an attempt to detect possible interactions of "global consciousness" with physical systems. The project monitors a geographically distributed network of hardware random number generators in a bid to identify anomalous outputs that correlate with widespread emotional responses to sets of world events, or periods of focused attention by large numbers of people.[1][non-primary source needed] The GCP is privately funded through the Institute of Noetic Sciences[2][non-primary source needed] and describes itself as an international collaboration of about 100 research scientists and engineers. Skeptics such as Robert T.
