Gravitation, or gravity, is the natural phenomenon by which physical bodies attract each other with a force proportional to their masses, and inversely proportional to the square of the distance between them. It is most commonly experienced as the agent that gives weight to objects with mass and causes them to fall to the ground when dropped. The phenomenon of gravitation itself, however, is a byproduct of a more fundamental phenomenon described by general relativity, which suggests that spacetime is curved according to the energy and momentum of whatever matter and radiation are present.
There are a number of daily chores, activities and trifles that require a distinct amount of care and attention when in space that are inversely proportional to the care the same activities require back on Earth. In a recently released video Chris Hadfield, the commander of the Expedition 35 crew now living aboard the International Space Station [...]
Evidence of drowned remnants of an ancient microcontinent have been found in sand grains from the beaches of a small Indian Ocean island, according to a new research. Zircons and volcanoes This evidence was found in Mauritius, a volcanic island 900 kilometres east of Madagascar which serves as an exotic destination for many tourists. Basaltic [...]
The (still debated) asteroid that slammed into the Earth 65 million years ago and played a crucial role in wiping dinosaurs out, may have actually been a binary system- 2 asteroids engaged in an orbit around each other. Double trouble The surprising claim comes from analyzing the proportion of asteroid craters on Earth that were [...]
As I was telling you in a previous article, researchers from NASA have created a high-res gravity map for the Moon, using two twin man-made satellites – Ebb and Flow. The satellites have done their mission well, shedding light on many of the Moon’s features, but NASA isn’t planning a safe return for them: they [...]
The Ebb and Flow satellites, known together as the Grail mission are mapping the slight differences in gravity across the Moon. The results show that the Moon received a much bigger battering than previous expected. A troubled past Beneath its surface, the Moon’s interior bears clues from the very early solar system – unlike the [...]
Panaji (Goa-India), Dec 12, 2011: Hunt for finding the hypothetical massive elementary particle, the Higgs boson, popularly known as ‘The God Particle’. Exploring the pulls and pressures among the planets and the dark matter above. Building capacities to explore hitherto lesser known Universe to benefit humanity using science and technology tools through global collaborative efforts. [...]
Contrary to what you might expect, a recent published study unveiled by scientists shows a map of our planet’s gravity, which resembles not a sphere, but more a … potato. This is because the Earth’s gravity isn’t uniform, being affected everyday by such factors like winds, currents and tides, so because gravity is higher in [...]
Aside from looking just awesome, these tests should also give new insights on water in 0 gravity and furthermore, inspire the new generation of space explorers.
Every day you hear about locations where the laws of physics appear not to apply or where anomalies take place every day; a big part of them are just hoaxes or are caused by misinterpretation of data but there are some which we have not been able to explain. According to an austrian physicist the [...]
