The Fermi Paradox is not a paradox at all in my opinion because the distances between the stars have not been understood well as it seems. With conventional means interstellar travel is impossible. Even if we assume some civilizations are technologically advanced that doesn't imply they could make contact or be able to find us.
There is also the problem of synchronicity. Civilizations don't last forever and advanced civilizations may have existed in the past, let's say hundreds of millions of year ago, but they have now gone. They are extinct. These civilizations will never be able to find us and vice versa as we live through different eras.
The other problem is self-destruction and we could argue that intelligent civilizations are destroyed before reaching sufficient advancement to make contact and this is another factor we need to consider.
The probability we are the only ones in the Galaxy is miniscule. The ingredients needed for life are the same everywhere and in very large quantities. Consider our Galaxy, the Milky Way, that contains at least 100 billion stars and as many at least as many planets. The Universe is an area that contains up to 2,000 million Galaxies which on average contain around 100 billion stars...
The numbers are huge and the most likely scenario is that life is present and was present everywhere. The problem is elsewhere and it has to do with the distances, the era in which civilizations exist, extinctions before reaching very advanced civilization levels, and the speed at which radio signals are travelling.
Unless some civilizations have already found the means to manage interstellar travel. Non conventional of course.
Quote:A new paper taking a look at the Fermi Paradox using the Drake Equations has suggested an uncomfortable solution: maybe we are alone in the galaxy.
If you haven't heard of the Fermi Paradox, it goes something like this: given the vastness of the universe and the probability that implies of life evolving elsewhere, how come no alien civilization has ever gotten in touch? We have found many exoplanets in the brief time we've been looking. Surely there must be someone else out there who, like us, desperately wants to find others
