Gravity waves affect the climate and weather. (eijournal.com)
instead of electromagnetic field, for use to sustain the plasma core in fusion energy power generators?if LIGO detected the gravitational waves, the next step would it be a gravity field generator? (topprice.in)
I suppose, making an extrapolation, that like discovering electromagnetic waves/field were followed after short time by discovering of the electric power generating methods/generators,the discovering of the gravity waves/field should do possible the same step after. (topprice.in)
I will summarize the history of gravity waves including the rejection of Weber's claim around 1975, his later work on gravity waves, and examine the reaction of the physics community to his neutrino hypothesis. (nautil.us)
An interesting case of this involves Joseph Weber, who pioneered the development of an experimental apparatus designed to detect gravity waves, and who later claimed to have observed those waves. (nautil.us)
Weber had connected his theory of the scattering of gravity waves, designed to show the increased sensitivity of his gravity wave antenna, to the scattering of neutrinos. (nautil.us)
In this essay I will briefly summarize the early history of gravity waves until the rejection of Weber's claim around 1975, and follow Weber's work on gravity waves until 1984 when he published his neutrino hypothesis. (nautil.us)
In this case, the physics community was forced to compare Weber's claims that he had observed gravity waves with the reports from six other experiments which failed to detect them. (nautil.us)

David - I think there might be a misconception here that, as you get further and further away from the Earth, you're feeling less of a gravitational pull and at some point you stop feeling the pull of the Earth's gravity. (thenakedscientists.com)
They're still experiencing the Earth's gravity but so is the spaceship that they're in. (thenakedscientists.com)
I read somewhere that the earth's gravity extends to a distance billions of light year away, in fact as old as the earth itself. (thenakedscientists.com)
The gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation). (wikipedia.org)
Near Earth's surface, the acceleration due to gravity, accurate to 2 significant figures, is 9.8 m/s2 (32 ft/s2). (wikipedia.org)
This quantity is sometimes referred to informally as little g (in contrast, the gravitational constant G is referred to as big G). The precise strength of Earth's gravity varies with location. (wikipedia.org)
Gravity on the Earth's surface varies by around 0.7%, from 9.7639 m/s2 on the Nevado Huascarán mountain in Peru to 9.8337 m/s2 at the surface of the Arctic Ocean. (wikipedia.org)
Calculating the gravity at Earth's surface using the average radius of Earth (6,371 kilometres (3,959 mi)), the experimentally determined value of the gravitational constant, and the Earth mass of 5.9722 ×1024 kg gives an acceleration of 9.8203 m/s2, slightly greater than the standard gravity of 9.80665 m/s2. (wikipedia.org)
This counteracts the Earth's gravity to a small degree - up to a maximum of 0.3% at the Equator - and reduces the apparent downward acceleration of falling objects. (wikipedia.org)
The second major reason for the difference in gravity at different latitudes is that the Earth's equatorial bulge (itself also caused by centrifugal force from rotation) causes objects at the Equator to be further from the planet's center than objects at the poles. (wikipedia.org)
Gravity decreases with altitude as one rises above the Earth's surface because greater altitude means greater distance from the Earth's centre. (wikipedia.org)
The mission, comprised of identical twin satellites, will precisely measure Earth's shifting water masses and map their effects on Earth's gravity field. (sciencedaily.com)
As they race around the globe 16 times a day, the satellites will sense minute variations in Earth's surface mass below and corresponding variations in Earth's gravitational pull. (sciencedaily.com)

While a hydrological model-based estimate considers geology, terrain, and hydrometeorological conditions, GRACE gravity observation includes groundwater withdrawal from aquifers. (iwaponline.com)

In plants, gravity sensing is orchestrated by specialized cells called statocytes that contain starch-filled plastids (amyloplasts) called statoliths, whose positions are influenced by the direction of gravity. (plantae.org)
Plants perceive the direction of gravity during skotomorphogenic growth, and of gravity and light during photomorphogenic growth. (bvsalud.org)

Amyloplast sedimentation repolarizes LAZYs to achieve gravity sensing in plants. (nih.gov)

From the earliest stages of perception, it appears, the senses are enhancing, competing with, and even altering one another in surprising ways. (bostonglobe.com)
Since then, a new field has emerged to study cross-sensory perception, with laboratories throughout the world devoted to understanding how the senses merge. (bostonglobe.com)

In combination, the equatorial bulge and the effects of the surface centrifugal force due to rotation mean that sea-level gravity increases from about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the poles, so an object will weigh approximately 0.5% more at the poles than at the Equator. (wikipedia.org)

ALL zero gravity non sense is in a descending plane or green schwimming pool. (thenakedscientists.com)
Another possible trigger is a conflict in inputs between angular motion and linear acceleration or gravity, as can occur in a zero-gravity environment when turning (angular acceleration). (msdmanuals.com)
Also, a pattern of motion that differs from the expected pattern (eg, in a zero-gravity environment, floating instead of falling) can be a trigger. (msdmanuals.com)

For example, visual input that indicates being stationary may conflict with the sensation of movement (eg, looking at an apparently unmoving ship cabin wall while sensing the ship rolling). (msdmanuals.com)
The balance system enables us to sense where we are in space and to maintain our posture and equilibrium while we are still and while we are in movement. (cdc.gov)

Gravitational acceleration contributes to the total gravity acceleration, but other factors, such as the rotation of Earth, also contribute, and, therefore, affect the weight of the object. (wikipedia.org)

Over the past decade, previously disparate studies of the senses have begun to merge. (bostonglobe.com)

If you double your distance from the centre of the Earth, the gravity would decrease to a quarter of what it is at the surface, but that's not zero G. (thenakedscientists.com)
Zero G in space is because you're in a space capsule accelerating under gravity, orbiting the Earth, or going from one body to another and you're not accelerating [relative to the spacecraft]: the person within the spaceship is accelerating at the same rate as the vessel. (thenakedscientists.com)
Chris - So people who are on the International Space Station, the reason that they are in orbit around the Earth is because gravity is hanging onto them and keeping them in orbit? (thenakedscientists.com)
the reason that Pluto is 6 billion kilometres from where we are here on Earth and it's still orbiting the Sun is because the Sun's gravity is hanging onto Pluto, even though it's that far away. (thenakedscientists.com)
Presuming the Earth is in an optimal orbit relative to it's mass and composition, as science and ToR tell us, and relative to gravity, or the gravitational pull of the sun at this distance away. (thenakedscientists.com)

A special issue of Remote Sensing (ISSN 2072-4292). (mdpi.com)

The objectives of this study were to evaluate the use of the center-of-gravity-based and center-of-pressure-based gait measures associated with loss of balance as well as the use of perceived sense of postural sway and instability (PSPSI) for the prediction of slip occurrence during dynamic task performance. (cdc.gov)
We often do not consider balance as a 'sense' in the same way that we think of seeing, hearing, tasting, smelling, and so on, because balance is usually an automatic, unconscious process. (cdc.gov)
1995). Balance disorders restrict an individual's normal motor activities, thereby limiting one's sense of independence and adversely affecting the quality of life. (cdc.gov)

Here we address this lacuna by contributing a novel remote sensing approach for investigating legacies of human-environment interaction on landscapes that have a long history of co-evolution with highly mobile foraging communities. (frontiersin.org)
