Holes in Domes Must Stay says Source

In a bizarre twist of historical news, an inside source informs WUAPASS that a Secret Space Force agent, a timeline preservation soldier who blocks would be time travelers attempting to interfere with historical timelines claims, "We have to stomp it out, either before or after they go back to the past to try to influence future events. So the events which have happened that are on our current timeline, which is a very solid timeline actually, have to have happened in the past. Major historical events, like presidential assassinations, you know - Lincoln, Kennedy - we just can't let anybody change those events, unfortunately, because we are on such a solid and stable timeline. So we gotta let those holes in domes stay."
