hubble law การใช้

• He thinks that discordant redshifts = intrinsic interpretation of the Hubble Law.
• This is what is used in the Hubble Law.
• The majority of the red shift is caused by the expanding universe and increases with distance dramatically, see Hubbles law.
• The Hubble law's linear relationship between distance and redshift assumes that the rate of expansion of the Universe is constant.
• There are ideas that are ( rather loudly ) trumpeted by nonstandard cosmology proponents as alternative mechanisms to get around Hubble Law.
• In 1927, the Catholic priest Georges Lema顃re proposed an expanding model for the universe to explain the observed redshifts of spiral nebulae, and calculated the Hubble law.
• However, this alleged astronomer rather cavalierly uses the " Doppler effect " as synonym for the Hubble Law, which is not uncommon but a definite mischaracterization that itself obfuscates the situation ( c . f.
• Even for small " z " the velocity entering the Hubble law is no longer interpreted as a Doppler effect, although at small " z " the velocity-redshift relation for both interpretations is the same.
• What you and Art may not have realized at the time is that anti-bangers like to use the Wolf Effect as a " change the subject " whenever somebody points out that the Hubble Law directly implies an expanding universe.
• The only offered criteria for distinguish as to what an " alternative redshift theory " entails are specific applications of the ideas of certain proponents of alternative cosmologies-- namely, those nonstandard advocates who have novel proposals that allow them to acheive a Hubble Law observation in their non-expanding universe.
• For more distant galaxies, then, whose light has been travelling to us for much longer times, the approximation of constant expansion rate fails, and the Hubble law becomes a non-linear integral relationship and dependent on the history of the expansion rate since the emission of the light from the galaxy in question.
• Unique to universes described by the FLRW metric, a de Sitter universe has a Hubble Law that is not only consistent through all space, but also through all time ( since the deceleration parameter is q =-1 ), thus satisfying the perfect cosmological principle that assumes isotropy and homogeneity throughout space and time.
• Their great white hope is to show that redshifts can occur without expansion of the universe . ( The typical exchange is something like " The Hubble Law is only explainable in a universe that follows the cosmological principle as a metric expansion, " saith the astronomy text . " The Wolf Effect causes redshifts without expansion, " saith the anti-Banger . ) That's what confused me so much by your insistence that I was POV-pushing a strict astronomy perspective ( at the time ) and now a " particle physics " perspective.
