The Fermi Paradox has been a topic of keen debate amongst scientists, astronomers and the rest of us for more than seven decades. We can't resist the urge to speculate about aliens! But what is the paradox even really about? What explanations have been offered? Today, we explore this famous question, and offer a mind-shifting explanation.
Written and presented by Prof David Kipping.

This reminds me of a joke I heard once.
Some aliens are passing Earth and do a quick scan. One says, " This species has satellite base weapons." So the other alien ask, " So they are an intelligent species?" The first alien replies with " No, they have them aimed at each other." It a little dark.

I've always contributed it to the fact that the universe is so unfathomably large that the distance between life forms is just beyond comprehension

"when was the last time you tried to converse with an insect" great line

The universe is likely many orders of magnitude larger than we can see. What we've done so far is like looking for fish in a teaspoon of seawater.

I heard a really interesting solution to the fermi paradox from a biologist. She was citing a recent paper where we found that phosphorus is not as common in the galaxy as we initially thought. In fact we have somewhat of a lottery winner here on earth with drastically high amounts as compared to other star systems. Phosphorus is a key ingredient in the storing and transferal of biological energy all the way down to the level of binding DNA together. She said that the paper she had read stated that phosphorus is one of those heavier elements that are formed in supernovae instead of just from fusion and so it is possible that, despite the age of the universe, there has not been enough time necessary to create enough phosphorus for other life to arise. And just like how we're "lucky" to be on the planet that has essential liquid water, we could simply be "lucky" to be in the corner of the universe, in the corner of the galaxy, which has just high enough concentrations for life to have formed here.
If that were the case, then we are the precursors who will likely die out as a species long before enough phosphorus is created to support the types of galactic communities we dream of. It may very well be that eons from now, as the universe begins to evolve space faring civilizations, that our ruins are discovered scattered across the stars, and they translate our records of how alone we feel.

I appreciate your remark on semantics. It is very important for figuring out "which question we are discussing", otherwise the discussion could get too general and shallow

100 years ago we were still traveling by boat while only 20% of the population could read and write. This space party is just getting started.

I've probably watched hundreds of videos on the Fermi Paradox, and it's so great to see something actually added to the conversation. Someone with something new to say, instead of just essentially reading out the Wikipedia page. Thank you!

Anyone who takes the time to focus on and present nuance on a subject like this is amazing. Thank you for your amazing dedication and work Dr. Kipping. This channel is what I imagined future science documentaries to be when I was a child, before the dark times destroyed television.

Imagine a hypothetical comment section. You don’t see any comments, so you type “first” and hit send. You don’t reload the page, and therefore watch the whole video thinking that you were the first

The milky way is 100,000 light years across, the first signal we intentionally sent into space is only 50 light years away...the speed of light pales in comparison to the size of the universe

That this channel has less than 10 million subscribers is arguably more mysterious than the Fermi Paradox.

It’s quite possible that spacefaring civilization is rare because it requires a balance of ambition, discretion, and foresight which is difficult to achieve. Civilizations that have a strong tendency to explore and colonize may also be more prone to internal conflict that disrupts their progress. On the other hand, civilizations that are peaceful, stable, and happy might not care to go exploring. Finally, the resources required would need planning and development over long periods of time, whereas short-horizon use of the same resources would be a constant temptation.

I love your channel, and scientific judgments in various subjects. I love your voice and passion for the subject. Just thank you, Dr. Kipping 🤩👍

I watch these types of videos quite often. It’s usually repetitive and I learn nothing new. This channel though, never fails to teach me something new and leave me mind blown. Great job Sir!!!

Great video! I’m an astrobiologist, published and all. My opinion for what it’s worth is simply distance, time and the inverse square law. We have only had a bubble of radio waves going for 80 years, with the furthest chance for a reply arriving tomorrow being only 40 light years away, in a galaxy a 105,000 light years across. That’s only 0.03% of the galaxies diameter. The chances a technological civilisation is within that is minuscule.
Secondly is the inverse square law. The change any of our TV shows would “leak out”, and be detectable even by the largest telescope isn’t realistic. The signal would have attenuated well before a few light years. Of which there is only half a douzen stars at most in that sphere. Once again the chance a civilisation is in one of those few star systems out of hundreds of billions is low.
The answer to the paradox is space is really really big, and artificial radio sources are puny.

I freaking love it when you film in the woods. As an environmental science student with a fascination for physics and space, it's the perfect juxtaposition, talking about something so advanced in a setting so very primal. Poetic.

Thank you for your engaging and informative content! I just found you and am really enjoying your videos. You briefly mentioned the great filter, and I was hoping you'd expand on that theory some more considering the topic. Would you consider making a video about the great filter and perhaps how it relates to this video topic?

Imagine finding out that Fermi was only commenting on the slow service by the wait staff when he asked, “Where is everybody?”
