Tifft that galaxy redshifts come in bunched intervals rather than on a smooth continuum. Difficulties in measuring redshifts; Example of why Tifft's claims are unusual; Reports of studies that seem to confirm Tifft's claims; Other claims on Tifft. 年份: 1992 ...
So, something hide them at high redshifts. Merging could be an explanation, but it would require that already formed and old stellar systems would assemble on short timescales of 1 Gyr or less. Only a negligible fraction of the galactic mass in young stars has to be added, a rather ...
The theoretical estimate for this energy of empty space from quantum field theory is somewhere in the order of 1 X 10^120 (1 followed by 120 zeroes) larger than the value of λ astronomers observe out in the cosmos by looking at the redshift of supernovas. It's for good reason then,...

Question: What is an event horizon? Studying Black Holes: We know that black holes exist but due to their complexity we can only make a few conclusions about them. Scientists who study black holes admit that they break down the laws of reality, so matter and energy may not behave as they...
What is galactic astronomy? In what planetary order is Earth from the sun? What is space in astronomy? What is an extrasolar planetary system? What is the ecliptic? What is Kepler's first law of planetary motion? What was the Copernican Revolution, and how did it change the human view of...
It is only these AGNs that are defined as radio galaxies. What fuels "radio loud" active galactic nuclei? A multi-wavelength image of radio galaxy Centaurus A. (Image credit: X-ray: NASA/CXC/SAO; optical: Rolf Olsen; infrared: NASA/JPL-Caltech; radio: NRAO/AUI/NSF/Univ.Hertfordshire/...
It includes everything from the smallest particles to the largest galactic structures, and even the empty space between them. Dark matter and dark energy are mysterious components that make up a significant portion of the universe's total mass and energy. 7 Space Space exploration has captivated ...
While Aldebaran appears to be part of this large, V-shaped group, it is not an actual member. The Hyades cluster is one of the nearest galactic clusters, and it is roughly 130 light-years away in the center. This moving group of stars is drifting slowly away towards Orion, and in ...
