An interferometer is necessary to validate the Finnish researchers' hypothesis about coupled photons because it can provide precise measurements of the resulting thrust changes. Simply adjusting exhaust angles in an EM drive may not yield reliable data without the rigorous testing an interferometer offers. The need for peer review is emphasized, indicating that discussions on this topic may be premature without scientific validation. The moderators' role in managing the conversation is acknowledged, reflecting the cautious approach to speculative theories. Overall, the focus remains on the importance of empirical evidence in advancing the understanding of EM drive technology.
