I don’t understand how this channel has so many episodes of such a high quality, and still not getting a million subscribers.

Edit: I thought the numbering system they used referred to the actual number of episodes, thanks for letting me know.

[b.g.]

The filming dates of these episodes is really peculiar.

This is episode 1304, which means it was first broadcast in 2014. But if you're familiar with what some of these people look like today (e.g. Kaku, Guth, even Robert) it had to have actually been filmed many years earlier than 2014 (Kuhn is currently almost 80 years old and Guth looks MUCH older today than he does here).

He's been making CTT episodes off and on since 2000. I suspect a lot of the footage is simply recycled/re-edited footage from many years ago.

Why do most humans not ever ponder these higher mysteries? Most are perfectly content going through life without thinking about these fundamental “laws”. I love the Universe, I hope I never stop having the ability to ponder and observe it.

[EugeneKhutoryansky]

I was disappointed at Kaku's discussion of Proton decay as if it is a fact, when he should know that it is purely theoretical, it violates the standard model, and it has never yet been observed.

[HakWilliams]

The universe will never end. It's got that sigma energy.

[hybridwafer]

Michio Kaku is always such a drama queen. He knows very well that the Milky Way won't "die in fire" upon merging with Andromeda. Stars are so far apart that it's improbable that any single collision will take place.

I thank you dear sir for “your wisdom held questions”, helps us commoners to learn a lot

"Dark energy is a code name for our ignorance". - beautifully and honestly described as scientists do. If only religions could be so honest and pragmatic.

[JohnCompton]

I find this subject fascinating but sometimes the answers get a bit more than i am able to conceptualize. Saul Perlmutter is always a welcome sight to articulate very heady subject matter in a form i can digest.

Tegmark: "Dark energy is just a code word for our ignorance." My sentiments exactly.

[jhunt]

The idea of a multiverse where all infinite possibilities occur is terrifying. Because worlds like ours, and worlds far worse than ours will reiterate infinitely. Infinite holocausts, infinite animals being preyed upon, infinite wars and torture. Sure there will also be infinite good things happening. It's still terrifying to ponder.

[fabsouth]

This is one of the most fascinating and interesting topics that we can ever expect to experience on a platform like YouTube I am so grateful for this channel

[chinemeremohaeri]

I think what he's trying to say is that nothingness cannot finish.

[georgederby]

I've watched all of these physics documentaries and shows for years and years... I probably seen most everything made... And michio by far is the most proud to be a physicist. Each time I hear him talk he says the same thing... "We physicist think"

ETERNAL UNIVERSE
Those who say the universe will end may well be underestimating the universe. End? What does that mean in the context of a permanently changing universe? The cosmological constant is dynamically constant. That is, it's unending change. The universe is simpy permanent change: motion, dynamism, transformation, with long periods of slow motions that gives the impression of steady states. Balance and disruption are its behavioral patterns. So where the universe is concerned phrases like beginnings and endings have no meaning. Sentient beings have birth and death cycles. But the universe simply unfolds as it must. Big crunch, cold fading away into nothingness, or escape into multiverses via inflation, all do not signify any end of the universe. On the contrary, ETERNITY is the natural state of the universe, with or without us, or living forms known to us humans. If this does not humble homo sapien sapiens, what will?

"Our Milky Way galaxy will probably die in fire as it collides with Andromeda". Which is contrary to the views expressed by cosmologists. It would be good to have, at least, a simple explanation of the whys and wherefores regarding the formation of 'Milkomeda'.

[rclrd]

It's amusing the way people talk about "we", as if human beings will still be around over the time scales they're speculating about!

[fortuner]

In the next millennium people will look at videos like this and think how quaint it is that we knew so little and troubled our minds with things we knew nothing about. I

[percentSNAFU]

Will the universe end? I don't think it will, or if so, that another version will be reborn. Time and the universe doesn't begin or end, it just has always been and always will be, in some form or another. Why? Because something exists. And because something does exist, something MUST exist, and nothingness can't exist.
