One of the problems (of many) with the YEC approach is that they have to rework all of the physics of the reality of the earth and the cosmos to force fit it to an interpretation of the Bible that they humanly presume to be infallible. And they contradict the Bible in the process.
Every time there is a new discovery which contradicts their skew (which is almost always), they have to back up and punt, missing the goal of truth.
Truth comes from reality – the truth that comes from the reality of the data that God has revealed in the Bible and the truth that comes from the reality of data that God has revealed in creation. They do not and cannot conflict. If they appear to, then our interpretation of one or the other or both is flawed.
