^^^ Special Relativity has been falsified, deal with it.
Because... you say so? Where is the evidence for that? I googled what you said and I saw no results supporting your statements, even if there was 1 or 2 sites somewhere saying that, why should we trust them? Are you a scientist? How are you judging their results?
In 1939 Dufour & Prunier performed a replication of the Sagnac Experiment that accounted for rotating frames of reference and it falsified special relativity. This is where the theoretical argument for gravity and black holes ends. There's no retreating to Newtonian gravity either, it's over.
