The Lead

Describing the universe requires fewer dimensions than we might think. New calculations show that this may not just be a mathematical trick, but a fundamental feature of space itself.

Is the Universe a Hologram? New Calculations Suggest Holographic Principle Holds in Flat Spacetime

April 27, 2015 11:03 am | by TU Wien | News | Comments

At first glance, there is not the slightest doubt: to us, the universe looks three-dimensional. But one of the most fruitful theories of theoretical physics in the last two decades is challenging this assumption. The "holographic principle” asserts that a mathematical description of the universe actually requires one fewer dimension than it seems. What we perceive as 3-D may just be the image of 2-D processes on a huge cosmic horizon.

Part of Italy’s Molise, Apulia and Campania regions are pictured in this radar composite image from Sentinel-1A. The area features two distinct types of terrain: the Apennine Mountains in the lower left and lowlands to the right. Known for its agricultural importance, the lowland area is known as the Tavoliere — a term that recalls the word tavolo meaning ‘table.’

Just as the extraordinary capabilities of 3D printing have begun to infiltrate industry and the family home, researchers have started to develop 3D printed materials that morph into new structures post production, under the influence of external stimuli, such as water or heat — hence the name, 4D printing.

Huge Magma Chamber Spied under Yellowstone Supervolcano

April 24, 2015 1:58 pm | by AP | News | Comments

Scientists have spied a vast reservoir of hot, partly molten rock beneath the supervolcano at Yellowstone National Park. It's big enough to fill the Grand Canyon 11 times over. The gigantic magma chamber is four times bigger and much deeper than the previously known chamber above it. The upper chamber was responsible for three ancient volcanic eruptions that coated much of North America in ash.

On April 25, 1990, astronauts aboard the Space Shuttle Discovery deployed the Hubble Space Telescope into Earth orbit and launched a new era of astronomical discovery. In its quarter-century in orbit, the world’s first space telescope has transformed our understanding of our solar system and beyond. Now, 25 years later, organizations around the world are joining in a celebration of this remarkable observatory.

Cosmic Rays used to Model Thunderclouds on Earth

April 22, 2015 2:17 pm | by Radboud University | News | Comments

How is lightning initiated in thunderclouds? This is difficult to answer — how do you measure electric fields inside large, dangerously charged clouds? It was discovered, more or less by coincidence, that cosmic rays provide suitable probes to measure electric fields within thunderclouds. The measurements, including the strength of the electric field at a certain height in the cloud, were performed with the LOFAR radio telescope.

Astronomers may have found "the largest individual structure ever identified by humanity." In 2004, astronomers examining a map of radiation left over from the Big Bang discovered the Cold Spot, a larger-than-expected unusually cold area of the sky. The physics surrounding the Big Bang theory predicts warmer and cooler spots of various sizes in the infant universe, but a spot this large and this cold was unexpected.

Where does Lightning Flash most Frequently?

April 17, 2015 3:16 pm | by NASA | News | Comments

According to satellite observations, lightning flashes more often over land than over the oceans. And lightning seems to happen more often closer to the equator. The NASA Earth Observatory’s Global Lightening Activity Map shows the average yearly counts of lightning flashes per square kilometer from 1995 to 2013. Areas with the largest number of lightning flashes — as many as 150 per year per square kilometer — are bright pink.
