Warning: If you haven't seen Avengers: Infinity War yet, firstly why not? And secondly, they will be a lot of spoilers about the movie in this article so proceed with caution.
So, if you're a Marvel fan you'll be aware that big bad of the movie is Thanos and his goal is to wipe out half of the population of the universe and restore balance.
Surely, he couldn't actually succeed in this plan. After all, it's Hollywood and the good guys always win, right?
Wrong, the Avengers fail miserably and a lot of people die as a result including some of your favourite characters... why do you do this to us Marvel?
Anyway, if Thanos was actually able to visit the real world he would be able to defeat us quite easily as our closest version of Iron Man is Elon Musk, who doesn't even have a special suit - just rockets.
All it requires you do is to click on it and you will be greeted with one of two messages. Either 'You were spared by Thanos' or 'You were slain by Thanos, for the good of the Universe'.
It's purely random, just like Thanos intended, and it doesn't change no matter how many times you click on it. Thanos has spared this writer several times.
