Question: why did you choose to look for tiny groups of galixies and not someting else?

In fact I choose to work with my supervisor because I thought he would be a good person to work with. The reason he is looking for the most distant galaxies is because it is like looking back in time and so we can try and work out how galaxies evolve and grow. It takes time for the light from these distant galaxies to get to us and so we see them as they were when that light set of. Like if you get a letter from your gran it tells you about stuff that happen yesterday. She can’t tell you what was on the news today.
