(Phys.org) —Scientists have many tools for measuring the cosmic structures of the universe, which includes structures such as galaxies, galaxy clusters, and intergalactic gas. Cosmic structures can be observed directly, such as by observations of large-scale structure, or indirectly, such as with experiments that measure temperature fluctuations in the cosmic microwave background. Although having multiple ways to measure cosmic structure is beneficial, there is one problem: the measurements don't agree.
