The Sun is the source of the overwhelming majority of light, heat, and energy on Earth’s surface, and is powered by nuclear fusion. But without the quantum rules that govern the Universe at a fundamental level, fusion wouldn’t be possible...
The conventional way we display annual calendars, at left, requires us to examine each month separately, either relegating the full year to a tiny font on a single page or onto 12 separate pages. Instead, the one-page calendar, at right,...
This image shows a slice of the matter distribution in the Universe as simulated by the GiggleZ complement to the WiggleZ survey. There are many cosmic structures that seem to repeat on progressively smaller scales, but does that imply that...
It’s not only the gravity from galaxies in a cluster that reveal dark matter, but the ejected, intracluster stars actually trace it out.Continue reading on Starts With A Bang! » Source link...
While we often imagine that an alien civilization that’s intelligent and technologically advanced will be far more advanced than we are, we should keep in mind that our technology should at least be capable of detecting the types of signals...
Whether we examine satellites orbiting around planets, planets orbiting around stars, stars moving around a galaxy, or galaxies moving within a galaxy cluster, the effects of gravity are what keep these objects moving in bound, stable orbits. Measuring the properties...
Taking us beyond the limits of any prior observatory, including all of the ground-based telescopes on Earth as well as Hubble, NASA’s JWST has shown us the most distant galaxies in the Universe ever discovered. If we assign 3D positions...
Rogue planets may be numerous in the galaxy, but it surprises most to learn that there are between 10 and 100,000 rogue planets for every star in our galaxy, putting the total number of planets wandering through the Milky Way...
From our own perspective on Earth, we’ve identified the presence of spiral arms.By viewing the Milky Way in infrared wavelengths of light, we can see through the galactic dust and view the distribution of stars and star-forming regions behind them....
Quantum gravity attempts to combine Einstein’s general theory of relativity with quantum mechanics. Quantum corrections to classical gravity are visualized as loop diagrams, as the one shown here in white. Alternatively, it’s possible that gravity is always classical and continuous,...
