Sentences with phrase «under gravity at»

The controversial experiment seemed to fall foul of Einstein's equivalence principle, which states that all objects should accelerate under gravity at the same rate.

Not exact matches

QM implies a rejection of locality and realism: locality means no instantaneous «action - at - a-distance» (as in Newton's formulation of gravity, although Newton apparently doubted this himself), realism means that the object under consideration is «there» even when not being observed.

Newton does not believe that gravity is an essential property of matter, but he also denies that it can be a force that acts at a distance.15 Newton is clear on one point with regard to his analysis of gravitation; he is concerned with the mathematical treatment of gravitation, not with the nature or causes of gravitation or the manner in which gravitation acts but with the conditions under which gravitation acts (PNP 5f, 192).

And by testing the effect of gravity on BECs of two different types of atoms, an atom interferometer could test the principle that all objects, no matter their weight or composition, accelerate at the exact same rate under gravity's pull — as Galileo Galilei supposedly demonstrated by dropping balls of different materials off the Leaning Tower of Pisa in Italy.

A French satellite experiment has shown that objects with different masses fall at exactly the same rate under gravity, just as relativity dictates.

Along with black holes, neutron stars are the result of stars collapsing under gravity once their fuel burns out, until their density is about the same as that of the nucleus of an atom, at which point the protons and electrons «melt» into pure neutrons.

The material at the centre of a neutron star isn't stable except under star - mass gravity — it decays into everyday...

Dimitrios Psaltis, an astrophysicist at the University of Arizona, is helping to test what may be general relativity's most extreme prediction: that large - enough stars will eventually collapse under their own gravity to form these infinitely dense objects.

After all, we aren't that great at second - guessing aspects of classical reality, either: how many of us would naturally say that feathers and bricks fall at the same rate under gravity?

Oils such as pentane have a low surface tension — 15mN / m — so they sag under gravity and tend to form a flat pool rather than a spherical droplet, meeting the surface at a low angle.

NAKED singularities and cosmic censorship may sound like lurid terms from the tabloids, but in fact these phrases lie at the heart of a troubling question for modern cosmology: what happens when our known laws of space and time break down, as happens in the final moments of a star collapsing to a point under its own gravity?

As he and his collaborators put it, «with at least a boundary layer of water on the diatoms, secreted oil droplets would separate under gravity, rising to the top of a tilted panel forming an unstable emulsion, which should progressively separate.

Decades of research indicate that when a star heftier than eight suns burns up its nuclear fuel, it will begin to collapse under its own gravity, starting at the core.

This so - called compactification generates a number of «modulus» forces, some of which would be comparable to gravity at distances approaching a tenth of a millimeter under certain string theory scenarios.

In the modern universe, black holes typically form from massive stars that collapse under their own gravity at the ends of their lives.

A cable made of carbon nanotubes, which have the highest known ratio of tensile strength to weight, would have to be so thick at the far end that it would collapse under gravity.

As a result, under such conditions the rainbow effect of quantum gravity could potentially be observed even at energies of particles hundreds of times smaller than the energy of protons in today's LHC.

After a postdoc at Princeton University developing experimental tests of gravity under physicist Robert Dicke, Weiss returned to MIT in 1964.

About 425 years ago, Galileo Galilei supposedly dropped pairs of balls of different sizes and materials from the Leaning Tower of Pisa to show that all objects accelerate at the same rate under gravity's pull.

Robin Canup of the Southwest Research Institute and Erik Asphaug of the University of California at Santa Cruz used a highly detailed computer modeling system — one that divided Earth and its impactor into more than 20,000 tiny particles whose interactions under stress both with each other and with gravity were simulated — to investigate their scenario.

«These non-silicate, granular materials can hold their electrostatic charges for days, weeks or months at a time under low - gravity conditions,» said George McDonald, a graduate student in the School of Earth and Atmospheric Sciences who also co-authored the paper.

A black hole is formed when a massive star starts running out of nuclear fuel at its interior (mainly hydrogen and helium) and begins to collapse under its own gravity.

Another study, which he published with Ezquiaga and others in April 2017, explored the theoretical conditions under which gravity waves could travel at a different velocity than light.

At the IAU's next general assembly in August 2006, it proposed a new definition of a planet: any body circling the Sun that forms itself into a sphere under its own gravity.

While there's the inevitable cross-over like Venice opener Gravity playing at TIFF along with Philomena, Under the Skin, Parkland, Joe, and many more, the Venice exclusives (at this point) make me want to book a Transatlantic ticket.

by Walter Chaw If it barely registers at under ninety minutes, Wes Craven's high - concept thriller Red - Eye is carried along by a couple of excellent lead performances (from Cillian Murphy and Rachel McAdams) and a revenge subtext that lends surprising gravity to the lingering sensitivity of a sexual assault victim's scars.

Power comes from three electric motors — one at the front and two at the back — providing all wheel drive for the Q6, with a large bank of lithium - ion batteries installed under the passenger area for a low centre of gravity.

Working against the iM is its weight: At just under 3,000 pounds, 137 hp is a somewhat meager amount of power to battle the forces of gravity.

Silhouette and rear end At the sides, subtle wedge - shaped and curving side character lines, along with a side under spoiler, accentuate the car's sporty, low centre of gravity.

That said, I also think we're hardwired at a very basic level to live under gravity.

For example, it has substituted ideal gas for real gas, so it actually has no atmosphere at all — only empty space with hard dots of massless, volumeless, weightless molecules without attraction and not subject to gravity zipping around at great speeds under their own molecular momentum miles apart from each other..

The formula you post at 6:22 am today is the correct definition of thermal conductivity of a gas under no gravity (there is no g in the formula) which B&A shows derives from the Fourier heat flow eqn.

3) The Fourier heat conduction formula is general for solids and is not applicable in general to fluids — only applicable to fluids with molecules not acted on by gravity; is applicable to ideal gas in gravity field only at boundary to a solid under certain conditions.

Real gases do not «spontaneously diffuse into the atmosphere under their own molecular momentum to travel at great speeds through empty space miles apart from other bouncing off each other in elastic collisions» of ideal gas — because real gas movement is inhibited by the individual volumes of other real gases around them, under the pulling power of gravity.

Also, this is ideal gas «constant rapid motion» by which it means travelling at great speeds through empty space, it does not mean the vibrational movement of the molecule which is anyway confined by by the other real gas molecules under gravity around it.

Glacier - A mass of land ice that flows downhill under gravity (through internal deformation and / or sliding at the base) and is constrained by internal stress and friction at the base and sides.

This type of accident is more common to vehicles with high center - of - gravity ratios like sport utility vehicles but any car can be at risk of a rollover under various circumstances.
