Upsurge in big earthquakes predicted for 2018 as Earth rotation slows Scientists say number of severe quakes is likely to rise strongly next year because of a periodic slowing of the Earth’s rotation Scientists have warned there could be a big increase in numbers of devastating earthquakes around the world next year. They believe variations in the speed of Earth’s rotation could trigger intense seismic activity, particularly in heavily populated tropical regions. Although such fluctuations in rotation are small – changing the length of the day by a millisecond – they could still be implicated in the release of vast...

Ever feel like there’s just not enough time in the day? Turns out, you might be onto something. Earth is rotating faster than it has in the last half-century, resulting in our days being ever-so-slightly shorter than we’re used to. And while it’s an infinitesimally small difference, it’s become a big headache for physicists, computer programmers and even stockbrokers. Why Earth rotates Our solar system formed about 4.5 billion years ago, when a dense cloud of interstellar dust and gas collapsed in on itself and began to spin. There are vestiges of this original movement in our planet’s current rotation,...

Planet Earth has recorded its shortest day since scientists began using atomic clocks to measure the speed of its rotation. Earth’s time systems can prove fairly baffling for anyone who doesn’t have a PhD in Horology, as we learnt the hard way trying to figure out why the clocks were going forward as a child – only understanding that we were being dragged out of bed for school an hour earlier than the week before. But the plot thickens further still, as Earth is actually spinning faster than it used to and recently recorded a time that was the fastest...

Google, Microsoft, Meta and Amazon launched a public effort Monday to scrap the leap second, an occasional extra tick that keeps clocks in sync with the Earth's actual rotation. US and French timekeeping authorities concur.Since 1972, the world's timekeeping authorities have added a leap second 27 times to the global clock known as the International Atomic Time (TAI). Instead of 23:59:59 changing to 0:0:0 at midnight, an extra 23:59:60 is tucked in. That causes a lot of indigestion for computers, which rely on a network of precise timekeeping servers to schedule events and to record the exact sequence of activities...

One of the big questions in solar physics is why the Sun's activity follows a regular cycle of 11 years. Researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), an independent German research institute, now present new findings, indicating that the tidal forces of Venus, Earth and Jupiter influence the solar magnetic field, thus governing the solar cycle.

“It could happen in a matter of months,” says Martin Mlynczak of NASA’s Langley Research Center. ________________ “The sun is entering one of the deepest Solar Minima of the Space Age,” wrote Dr Tony Phillips just six weeks ago, on 27 Sep 2018. Sunspots have been absent for most of 2018 and Earth’s upper atmosphere is responding, says Phillips, editor of spaceweather.com. Data from NASA’s TIMED satellite show that the thermosphere (the uppermost layer of air around our planet) is cooling and shrinking, literally decreasing the radius of the atmosphere. To help track the latest developments, Martin Mlynczak of NASA’s...

Planetary effects are too small by several orders of magnitude to be a main cause of the solar cycle.Argiris Diamantis writes in with this tip: Professor Cornelis de Jager from the Netherlands has put a new publication on his website. It is a study of Dirk K. Callebaut, Cornelis de Jager and Silvia Duhau. They conclude that planetary effects are too small by several orders of magnitude to be a main cause of the solar cycle. A planetary explanation of the solar cycle is hardly possible.The paper is titled:The influence of planetary attractions on the solar tachocline Dirk K. Callebaut...

The deadly tsunami on December 26, 2004 was the result of Saturn, Moon, Earth and the Sun falling in a straight line, claims a retired scientist of Department of Atomic Energy. Paramahamsa Tewari, who supervised construction of Narora and Kaiga atomic plants and authored controversial "space vortex theory", says his conclusion about the cause of tsunami stems from his theory that all spinning cosmic objects including the Sun develop electrical fields that repel each other. On the fateful day, Saturn, Moon, Earth and the Sun were perfectly aligned. As a result, Earth was subjected to the repulsive electrical force of...
