At extreme distances (over 1 billion light years) astronomers use hubbles law to determine how far away objects in our universe are away from us,

a) How are spectral lines used to help determine these extreme distances

b) Since Hubble's law relies on information from spectral lines, it can be said that spectral lines even help us estimate the age of the universe. How are spectral lines from galaxies at known distances used to determine hubbles constant, and how can the age of the universe be determined by hubbles conctant

    9/ the 2011 Nobel Prize in Physics was awarded to 3 men who study white dwarf supernova explosions, which are known as Type la supernovae. The following problem is designed to give you a feel for what they did, and the sorts of apparent brightnesses and distances they were working with. A typical Type la supernova explosion has a luminosity of 1.72 x 10^36 W. If we observe such a supernova to have an apparent brightness of 1.25 x 10^-17...

    The world’s 3 billion-plus smartphones emit the kind of data that health authorities covet during outbreaks. They show where individuals are, where they’ve been and who they might have talked to or even touched — potentially offering maps to find infected people and clues to stopping new ones. But gaining access to this data, even amid a global pandemic, is made complex by the legal and ethical issues surrounding government access to information that can reveal intimate details about citizens’...
