Hope you are enjoying the first second of existence (bit of a tangent this video, but an important part of the puzzle!) Next month let's find out what happened after particles gained mass. Spoiler: nothing not weird.

The simplest answer is that the universe is perfect from our point of view because we were created by it and are governed by its laws, so it couldn't be any other way.

A small token of my appreciation… one of my favorite channels, fascinating topics and clear, well researched explanations. Thanks! Andrea

[MattMartinGuitars]

It really blows my mind that videos like this are available, free of charge, to anybody in the world.

What a time to be alive...

[adrianaslund]

The sound design for these are so good. It's as unintrusive as possible without being forgettable. Pretty good tunes too

[Chrisbajs]

The quality of (some) YouTube videos has far surpassed the old fashioned media like television. It's amazing what level of quality and insight we can stumble upon while surfing YT, and thanks to the algoritm of recommendations, I was fortunate enough to find this utter gem.

[RyanTheHero]

I think we can say with great confidence that the creation of consciousness in this universe is the greatest phenomenon ever seen. Out of all the ways this universe fascinates us, the reality that self-awareness was created from some combination of unconscious matter is more mind-blowing than anything else

The simulation hypothesis has the same problem that the panspermia hypothesis does: it kicks the problem farther down the road without actually answering it. Whoever's running the simulation has to live in a universe that has constants compatible with life, so the question remains of how those conditions arose - just one level higher. I'm not saying the hypothesis is necessarily wrong, but it absolutely doesn't answer the question.

Editing to simplify/clarify my position: given that we are in a simulation, two questions that arise are "what conditions allow the simulation to be run?" and "how did those conditions arise?" *These are exactly the same questions the simulation hypothesis purports to answer about our own universe, * and the hypothesis is meaningless if those questions can't be addressed.

Another edit: if, as has been suggested several times in this thread, the intelligence running the simulation isn't subject to the same natural laws that we are, does that not inherently contradict the assertation that a "fine-tuned" universe is actually necessary in the first place?

Just brilliant as always. Calm clear diction, no distracting music. Incredible info expressed beautifully. ❤❤❤

I am so impressed how you perfectly combined a relaxing, and low, background music with such a fantastic narrative.
So many science documentaries that are terrible mixed and are anything but a relaxing lecture. This is not the case.
Its amazing how you control the aspects of the narrative, the pauses, the emphasis, the mistery and the logic with a precise description.
Your voice sounds from heaven. Thanks for your fanatstic job.

I enjoyed every second of this wow. These are the things I think about almost daily but never put the research into and you’ve just done it all so perfectly!

[spacekiwikit]

Watching your videos is like preparing for a wedding..Something old, something new, something borrowed and something blue..But always told in such a smooth and entertaining way, you can't help but be mesmerised by it.I love the mention of the Hitchhiker 's guide!

[BHJBHJ]

Documentaries on the Universe (heck, even the solar system) make me feel both totally irrelevant and totally unique and priceless at the same time

[Brucebod]

I love to watch your videos. I watch them late at night when all is quiet and I can immerse myself in the visuals and sound. They fire up my imagination spectacularly and I then can then drift to sleep with ease. Thank you for the work you put into these. I much appreciate them!

[armadillotoe]

The ability to see an event in mathematical terms is something I have always envied.
This video has a lot for my old fossilized brain to absorb. I am familiar with some of the concepts but not with all. Thank you.

[simpsonyellow]

Thank you for yet another incredibly high quality release. This channel is my absolute favourite little spot on YouTube.

[CharlesGorrie]

I’m loving having found this you tube channel. It is wondrous. It fills me even fuller of wonder than I could even imagine.

[matthewgumabon]

I think it’s cool to think that we (intelligent life) are the universe’s attempt to experience itself. The universe arranged itself in such a way to create beings that could sense and interact with its surroundings and even ponder itself and it’s purpose.
We are the very thing that we have toiled for generations to understand.

[DoomSkullYT]

i almost always fall asleep listening to this, it's just so smooth listening to these videos. I try to stay awake to actually take it in, but it just happens. Great video as always, can't wait for the next one!
Also just wanted to say I've recently begun my degree in physics with astrophysics.

[abhishekdas]

I am glad i subscribed to this channel and 'History of the Earth'. Your content is absolutely amazing and worth binging. Yesterday I re-watched some of your videos and was actually wondering when a new one would drop and here it is. Please keep up the good work and do upload new content in the Earth channel pertaining to the geological evolution.
