جهان قابل مشاهده بیش از ۲۰۰ میلیارد کهکشان دارد. هر کدام با میلیاردها ستاره. اگر حتی درصد بسیار کمی از آن‌ها میزبان حیات هوشمند باشند، باید نشانه‌هایی از تمدن‌های پیشرفته می‌دیدیم. اما واقعیت این است:

When discussing topics like The Fermi Paradox, one of the measurements scientists use to classify potential alien civilizations is by using the Kardashev Scale, which is a fascinating look at potential

1. From Earth, we can see Billions of stars, trillions including galaxies where we can't make out stars individually. 2. The Universe is approx 13 billion years old, which is a lot of time for life to emerge and multiple generations for large stars. Life has already emerged in one place at least in that time. 3. Under known physics, it should only take 2 million years at most for a civilization which has advanced to space travel to colonize an entire galaxy, if even a tiny tiny fraction of them want to. 4. If there are any civilization out there, we should see **clear** evidence of it. The fact that we can see stars at all should be surprising (this is known as the Dyson Dilemma) https://www.youtube.com/watch?v=QfuK8la0y6s 5, Among those billions/trillions of stars, we have not seen any evidence of extra terrestrial civilizations. Why don't we see any evidence of extra terrestrial civilizations? You can choose multiple answers, but keep in mind if they are compatible with each other (don't choose multiple incompatible answers). Answers are pulled from wikipedia

This post has two parts. First, I outline some way to evaluate arguments about the Fermi paradox which show ways that it is unlikely to be solved by, as well as some common arguments against the Early

One possible solution to the Fermi Paradox is, when a civilization invents technology, it inevitably invents AI, which eventually goes superintelligent. Then, Super AI discovers proof we are in a simulation

If you had a UFO providing power, food and everything you need for free, while letting you travel anywhere in the universe ... Would you stay in your apartment? ... Would you keep your job? Probably not.

Thoughts upon waking: A reasoning astrophysicist type regarding the Fermi Paradox offers: "Intelligent life with the ability to communicate across space is actually probably more rare than people

img credit The question we have been asking ourselves over and over is are we alone in the universe and if we aren't then where are all the aliens . The universe is big and its expanding on a daily basis

One of the possible solutions to the Fermi Paradox.
