The wave
I got a vision in my mind yesterday.A wave.
I was thinking, what if there is an event happening at some point in the future, an event so shocking to cause a big wave going backwards through time.
Now, maybe, if we carefully look at the event horizon, we can see the tip of the wave, and if we listen carefully, we can hear the low frequency noise announcing it.
The wave is going backwards through time and should hit us sometime soon.
No idea what would happen then.
