Such an explosion occurred in an alternate timeline in the 29th century, when Henry Starling, an industrialist from the 20th century, piloted the Federation Timeship Aeon into the future without properly recalibrating the ship's temporal matrix, resulting in the generation of an unstable temporal field which destroyed all of Earth's solar system in a temporal explosion. This lead Captain Braxton to the 24th century from which the Aeon was accidentally transported to 1967, completing the time loop. This timeline was later negated when the USS Voyager was transported back in time from 2373 to 1996, managed to destroy the Aeon with a photon torpedo moments before it entered the rift, thereby changing history such that the explosion never occured.
