In their paper, «Higgs Seesaw Mechanism as a Source for Dark Energy,» Krauss and Dent explore how a possible small coupling between the Higgs particle, and possible new particles likely to be associated with what is conventionally called the Grand Unified Scale — a scale perhaps 16 orders of magnitude smaller than the size of a proton, at which the three known non-gravitational forces in nature might converge into a single theory — could result in the existence of another background field in nature in addition to the Higgs field, which would contribute an energy density to empty space of precisely the correct scale to correspond to the observed energy deEnergy,» Krauss and Dent explore how a possible small coupling between the Higgs particle, and possible new particles likely to be associated with what is conventionally called the Grand Unified Scale — a scale perhaps 16 orders of magnitude smaller than the size of a proton, at which the three known non-gravitational forces in nature might converge into a single theory — could result in the existence of another background field in nature in addition to the Higgs field, which would contribute an energy density to empty space of precisely the correct scale to correspond to the observed energy deenergy density to empty space of precisely the correct scale to correspond to the observed energy deenergy density.

The key value involved in this scenario is the ratio between dark energy's pressure and density, what is called its equation of state parameter.

Since the research has repeatedly discovered that almost everyone will eat more when served larger portions from a larger plate or container, and there is obviously a serious issue of «portion distortion» occurring, another group of scientists and psychologists decided to test this even further by providing larger plates or containers of low energy density, high nutrient density foods before the main course and or in between meals.

In the current study, no positive association between the consumption of high - fat dairy products and weight gain was observed that might have been expected because of the higher energy density of these products.

Clear patterns were also not seen in the relationship between weight change and the energy density of dietary components (e.g., beverages of low energy density were strongly associated with weight gain).

Between this meeting and March, the Subcommittee would work on the issues of breakfast, energy density, the level of activity regulating appetite, portion sizes, and leisure time physical activity modes.

He suggested that rather than emphasizing the differences between weight loss and weight maintenance, the Committee should emphasize the commonality, which is energy balance — physical activity, combined with low - energy density food, healthy snacks, and portion size.

The energy flowing from the sun is intercepted by the earth with energy density described by the «solar constant «(S0 = 1366W / m2), and the amount of energy intercepted is the product between this flux density and the earth's disc (minus the reflected light due to the planet's albedo: A ~ 0.3).

regardless of individual constituents (limited by density changes) Because, in all the transport processes the energy can move between transport mechanisms in the air by molecular collisions every few centimeters.

5) A warming effect in the atmosphere arises because between coming in and going out the radiant energy is «processed» by the molecules in the atmosphere into heat energy and then back again, often many times for a single parcel of radiant energy, the number of times being directly proportionate to the density of the atmosphere.

It is the density, not the composition which gives more or less opportunities for such instances of energy transfer between molecules whilst the incoming and outgoing radiant energy is negotiating the atmosphere.

When CO2 molecules (or any other GHGs) absorb more energy than those around them their higher temperature increases the spaces between them and adjoining molecules reducing density and causing them to rise until they reach a height where they are at the same temperature as surrounding molecules.

The public has known for decades of the link between burning fossil fuels and global warming, yet society has continued to use oil and natural gas because there are still no alternatives that match their low - cost, their energy density, and their dispatchability.

But every one of these cases ignores the fact that the public has known about the link between burning fossil fuels and climate change for decades and has continued to rely on oil and natural gas because of its unmatched cost, energy density, and reliability.

So it's all gases at greatest density will be doing the same thing around the planet at the same time (*) and as these change with differences in density in the play between gravity and pressure and kinetic and potential from greatest near the surface to more rarified, less dense and absent any kinetic to write home about the higher one goes, then, energy conservation intact, the hotter will rise and cool because losing kinetic energy means losing temperature, thus cooling they which began with the closest in density and kinetic energy as a sort of band of brothers near the surface will rise and cool at the same time whereupon they'll all come down together colder but wiser that great heights don't make for more comfort and giving up their heat will sink displacing the hotter now in their place when they first went travelling.

The atmosphere is analogous to a flexible lens that is shaped by the density distribution of the gas molecules, of the atmosphere in the space between the sphere holding them, and space; Incoming heat gets collected in many ways and places,, primarily by intermittent solar radiation gets stored, in vast quantities, and slowly but also a barrage of mass and energy fluxes from all directions; that are slowly transported great distances and to higher altitudes mostly by oceanic and atmospheric mass flows.
