Are you kidding? An astrophysicist that could come up with a new model that explains the current data would win a Nobel prize and earth shattering levels of notoriety.
The data found doesn't contradict the big bang in any shape or form. It does challenge beliefs around black hole formation.
The reason for the big bang model is because based on all our measurements of all the visible universe, it appears that everything is spreading out. Any new model needs to explain why it is the universe appears to be spreading out.
There's not a scientist alive that wouldn't like to discover that "actually a fundamental principle about my field of study is completely wrong". But that takes hard work, evidence, and models which better fit than the previous ones did. You need to find something that can't be explained with the old model and can only be explained with the new model.
The Big Bang is an almost infinitely malleable story, contorted to comport with almost anything we observe. But how is this useful? The predictions of this theory continually fail. The farther we look, the more we see stars, galaxies, black holes, and other structures that shouldn't exist according to this model.
What if the universe doesn't have a naturalistic origin, but was created by God? How much greater would our understanding of the world be if more scientists focused on studying present phenomena rather than trying to fit stories about the past with observed data?
