From what I've read, it says that the hydrogen bom was actually the cause of the incident. It says that they revealed that in the finale. When in the finale do they ever mention the bomb? And how do we know from the reveal that the FST is the afterlife that the bomb was actually the incident (which is what Miles said)? I'm confused as to why it says om the Incident's page that the bomb mixed with electromagnetism caused the incident? If the bomb went off, it should have killed everyone. How did the bomb going off create the build up every 108 minutes? And how did it transfer them back to 2007? I'm confused on how we know from the finale that the bom was the incident.
