Scientists have recently found two stars that could possibly change the current understandings of physics and astronomy. Initially, these stars were thought to be neutron stars, which are the remnants of supernovas. However, they are smaller and cooler than neutron stars. Scientists hypothesize that these objects are indeed neutron stars but that they are just smaller and cooler than those that have been studied previously.

You may conclude from this selection that

more study is needed to determine what these stars are.

Explanation

The selection makes it clear that scientists are puzzled by these stars, and their “hypothesis” is that they are neutron stars.
