The information of underlying science about the Universe is given by looking at structure formation on large scales. While current observations revealed the breakdown of our knowledge of physical science on cosmological scales, the future observation of large scale structure formation from redshift surveys will provide us with a clue as to which part of our physical science should be modified -- matter or gravity.
