Sentences with phrase «energy scale of the universe»

Not exact matches

Given that the large - scale structure of the universe is dominated by the presence of still mysterious Dark Matter, and that on the smallest scales empty space sustains quantum oscillations whose energy density dwarfs that of all known forms of matter, we should hesitate to imply that the physical and spiritual realms can not be even partially consubstantial.

And on much larger scales, we see the effect of dark energy ripping the universe apart.»

By merging this concept of the early universe with specific mathematical models of the effects of dark energy, scientists were able to predict a characteristic scale — a typical distance between concentrations of galaxies — that should be evident in the structure of the universe.

The implications were astounding: Not only was there a cosmic force that seemed to be stronger than gravity, albeit only at gigantic scales, but also this force — later dubbed dark energy — seemed to constitute more than three - quarters of everything in the universe.

The microwave background marks the limit of the observable universe, nearly 14 billion light - years away, and Rudnick believes that the void, which is 6 billion to 10 billion light - years away, imprinted its form on the microwave background by the simple virtue of being empty: Under the influence of dark energy and gravity, space containing clusters of galaxies compresses microwaves to a shorter, warmer part of the spectrum, while space that is empty on this scale stretches and cools microwaves.

Up until recently, those seeking the exotica of the universe — dark matter as well as dark energy — focused on the very largest scales (galaxy clusters and up) and on comparatively small ones (a single galaxy).

Since dark energy works against gravity, more dark energy accelerates the universe's expansion and retards the formation of large - scale structure.

Dark energy is detected by its effect on the rate at which the universe expands and its effect on the rate at which large - scale structures such as galaxies and clusters of galaxies form through gravitational instabilities.

With current observations suggesting that dark energy comprises more than 70 percent of the matter - energy density of the present - day universe, astronomers say that measuring the apparent shapes and the distribution of galaxies in the Universe will constrain the nature of dark energy and allow them to examine whether the general theory of relativity is still a valid description of gravitation on scales of billions of light years.

Because of the extreme scales of distance and energy accessible in the universe, astronomical observations can probe particles and forces in ways not possible in the laboratory.

Rejecting firm distinctions among conscious, animate, and inanimate matter, these theories conceive the universe as a vast collection of self - organizing matter - energy flows operating at various scales.
