Dark matter and dark energy makes up 95% of the total mass-energy density in the universe. However, we know almost nothing about them; neither can we observe any dark matter or dark energy directly. So what if aliens are made of dark matter or dark energy? Can this be the reason we have not been able to find any aliens?

Somewhere in the universe is a small, blue planet, the third drop from a star called the Sun. Just one of billions of stars in a spiral galaxy known as the Milky Way. But where in the universe is the Milky Way?

A team of scientists gather data on more than 8,000 of the galaxies that surround us, they mapped each galaxies position and movement in space. And for the first time, they’ve shown that the Milky Way is part of a much larger system of galaxies - a super cluster that they have named Laniakea. The Milky Way is nested in the furthest reaches of this structure on the outskirts.

Publishing a new post can be too much if you do it old school hexo p && hexo d on the desktop/laptop. What’s worse is you can only publish it on a computer with Hexo installed. What if you want to write it anywhere and anytime and even on an iPad? With Travis CI (or any other CI service), each time you push a change to the GitHub repo, a build will kick off on Travis and it run anything you prepared including deploying the updated pages. It took me two nights to figure out (mostly) how to archive it :sweat_smile:, so in this post I will try to write down each step and the tricks within to make everyone’s life easier.
