Even if that were feasible, then it's not the solution I had in mind.
Its almost feasible with todays technology so I'd say in this senario it is definately feasible. If the colony on mars is not destroyed then the disaster, the extinction of all humans, is avoided.
Sorry, no Post-Of-The-Month yet.
That's ok, i don't care about the POTM.
if something from the future changes the past so that the future cannot happen the way it happened before, then it may not be possible to change the past from that changed future
Then what about the first time the infection happened, before the first message was sent?
The message couldn't have been created until the virus occured and the first time the message was sent back the future, and past, was altered. I think the senario implies that it is possible to change the past form the changed future.
So this time around, when the colony is saved there in no message sent and humans survive. The message that we just recieved (i mean you typed) is the second one mentioned. The humans that wrote it mentioned receiving a message and that is why they created the colony on mars. The first time the virus happened, there probably wasn't an effort to make a colony on mars because the virus was unknown. Now, that colony was destroyed so they sent the message again because they didn't no the asteroid was comming. This time we know its comming and can take anther step towards survival. Its seems that every time around the senario would change a little. I don't think it could be an endless loop that would never stop because it would be impossible for the loop to start.
But my goal with this thread was twofold: to have a little fun with a riddle, and to discuss time-travel paradoxes. The latter we have done, and can continue to do.
Consider your goals achieved.
But the riddle remains to be solved.
if you say so...
Here's a hint: the message indirectly causes the plague. The question is: how?
The Message writes:
Earth launched a mission to retrieve them and they made it back to earth in six months time. Then, in december 2113, the viral infection started.
Since the virus started after visiting mars the virus must have come from mars and the message is what made us go to mars in the first place, indirectly causing the virus.
But this ruins my previous solution because I said that the first time the virus happened we hadn't gone to mars so either way I'll consider it solved. Unless you say that it isn't again.
