Redshift is important because it has helped astronomers make observations about the universe. 红移很重要,因为它能帮助天文学家观测宇宙。 In 1929, the redshift of galaxies caused astronomer Edwin Hubble to discover that the universe is expanding. 1929年,天文学家爱德文·哈勃正是通过许多星系的红移发现...
Redshift, displacement of the spectrum of an astronomical object toward longer (red) wavelengths. It is attributed to the Doppler effect, a change in wavelength that results when an object and an observer are in motion with respect to each other. Learn a
"standard candle" supernovae which always have the same luminosity and observing that the farther they are, the more red shifted their light is, and since red shift indicates that an object is moving away from us, we assume that the whole universe is expanding, is this an accurate ...
How can this be so if the universe is expanding? Especially since this range of redshifts includes the supernovae data used to show 'acceleration' and so called 'time dilation.' Taking these results in isolation implies that the universe has been static for at least the last billion years...
The New Tired Light Theory (that redshift is due to electron interaction) is supported by the fact that measured values of the Hubble constant, H are exactly equal to a combination of the parameters of the electron. This is known as 'Ashmore's Paradox'.If, in the expanding Universe, the...
On the other hand, Doppler (blue) shift occurs when an object is moving towards the observer, causing a shift towards the shorter, blue wavelengths. How is expansion by Doppler (red) shift related to the expanding universe?Expansion by Doppler (red) shift is directly related to the expanding...
When the Doppler effect causes the shift, the object approaches (blueshift) or recedes (redshift) from the observer. We would observe a blueshift if the universe is shrinking and a redshift if the universe is expanding. When a gravitational effect causes the shift, the light is emitted from...
Modification of Redshift and Luminosity by Voids in the Expanding Universe : Astrophysics and Relativity Propagation of light in a clumpy universe is examined for redshift and luminosity. Taking a spherical void model and Swiss Chesse model, the modification i... S Humitaka - 《Progress of ...
The explanation of the red shift in spectra of remote galaxies and cosmic microwave background radiation from the concept of an expanding Universe seems inadequate, and invites other explanations. The present paper studies the idea of cosmic red shift and microwave background radiation as a consequen...
