Dominique Lambert explained first some of the background to Lemaître's work: In 1927, Mgr Lemaître was the first scientist to explain what we call today the «Hubble law», stating that the speeds of the far galaxies are proportional to their distances, in all directions of the universe.

4) then photons erupted from this energy 4) let there be LIGHT (1 - 4 all the first day) cloud (detectable today as the microwave background radiation) 5) photons and other particles form the 5) God next creates the heavens (what we call the sky) above bodies of the early universe (atoms, (2nd day) molecules, stars, planets, galaxies) 6) it rained on the early earth until it was 6) dry land appears as the oceans form (3rd day) cool enough for oceans to form 7) the first life form was blue green bacteria.

So when a dim star in our galaxy passes almost directly between Earth and a second star, the gravitational field of the intervening «lens» star bends and magnifies light from the background star, a process called gravitational microlensing.

The cluster is so massive that its powerful gravity bends the light from galaxies far behind it, making background objects appear larger and brighter in a phenomenon called gravitational lensing.

By combining these color data, it is possible to make a crude estimate of the distances to the faint background galaxies (called photometric redshift).

The team estimates that a background level of radiation, supplied by other galaxies, could delay gas in a galaxy (call it galaxy A) from fragmenting quickly into smaller clouds that would form stars.
