More ways to solve the Fermi Paradox

Wilczek also floats another idea - what if an alien civilization created a greenhouse effect to raise the temperature of a planet? For example, if extraterrestrials were currently researching Earth, they would likely notice the increased levels of carbon dioxide that are heating up our atmosphere. Similarly, we can looks for such signs around the exoplanets. An … Continue reading More ways to solve the Fermi Paradox

A list of solutions to the Fermi Paradox

As Tim Urban says, 'We’d estimate that there are 1 billion Earth-like planets and 100,000 intelligent civilizations in our galaxy.' So there must be aliens. Why haven't we heard from them? (Read about the Fermi Paradox here.) This blog is a list of answers. I've summed up each one in a line and dropped a relevant … Continue reading A list of solutions to the Fermi Paradox
