[[:en:Graphical timeline of the Big Bang]]

[[Image:Mrao ami lba ryle.jpg|thumb|250px|The AMI Large Array, utilizing antennas from the [[Ryle Telescope]]. The telescopes have been re-positioned since this photo was taken.]]

This '''timeline of the Big Bang''' shows the sequence of events as predicted by the [[Big Bang]] theory, from the beginning of time to the end of the [[Timeline of the Big Bang#Dark ages|Dark Ages]].

The '''Arcminute Microkelvin Imager''' (AMI) is an interferometer [[radio telescope]] designed principally to image secondary [[anisotropy|anisotropies]] in the [[cosmic microwave background]] (CMB) at higher angular resolution than the [[Very Small Array]]. It consists of two [[interferometry|interferometric]] arrays, the Small Array and the Large Array, sited at the [[Mullard Radio Astronomy Observatory]] in Cambridge (UK), both operating in the frequency range 12-18 GHz. The (short-baseline) Small Array consists of 10 3.7-m parabolic antennas while the long-baseline Large Array is composed of eight 13-m antennas. The two arrays have essentially identical receivers and back-end electronics.

It is a [[logarithmic scale]] that shows <math>10*\log_{10}</math> ''second'' instead of ''second''. For example, one microsecond is <math>10*\log_{10} 0.000 001 = 10*(-6) = -60</math>. To convert -30 read on the scale to second calculate <math>10^{-30/10} = 10^{-3} = 0.001</math> second = one millisecond. On a logarithmic time scale a step lasts ten times longer than the previous step.

The main goal of the project is to carry out a survey of clusters of galaxies via the [[Sunyaev-Zel'dovich effect]] (the scattering of the CMB off the hot gas in the cluster). AMI will also make very high-resolution observations of the primary CMB power spectrum.
