Where is everybody? Enrico Fermi asked this question in the summer of 1950 with fellow physicists and the Fermi Paradox born. There are immense number of answers to that question but personally I'm not convinced by them. But I cannot stop myself to think about big questions, so here is my answer.

Since my master thesis, "Holographic Superconductors and Rotating Black Hole", I'm getting thriled by superconductors. It's not the case for everything that I worked on! For instance, I'm not a fan of Ads/CFT that I worked on it back then. Nonetheless, superconductors are so fascinating. High-temperature superconductors could change our life in a way that we'll call it superconductor age, if we wouldn't get extinct by then, the same way that we had stone age, iron age, and we're living in the silicone age. Writing of superconductor age, a piece of puzzle that I'll write here about is a speculation that a version of superconductor age has already passed!

Mars’ surface gravity is 3.711 m/s² and Earth’s surface gravity is 9.807 m/s². That’s it! We cannot live on Mars because its surface gravity is half of what we evolved in for millions of years. But we spend billions of dollars for this target. Great! But what if it failed because of a simple fact that we ignored?

This article is not about nagging why others would fail, but instead here we want to come up with a simple solution that works best for the big problem we have. Earth is going to be destroyed soon if we continue living this way. This is the problem we all face if we open our eyes. Is this why we should go to other planets? In my mind, no! We need to go to other planets because our population grows exponentially, and we need new resources to make it sustainable.
