@@skywarior01 Yeah. Hitoshi taught me and several of my friends quantum field theory and he is by far one of the best English speakers in our department. In terms of teaching, he's number one in my book.
I'd also love to hear him talk more about his perspective etc. I recently got a chance to attend a lecture by Asian and African researchers and their techniques and perspectives were slightly different and that is really interesting too
I feel like having to read the subtitle helped me to grasp the concepts a bit more thoroughly and then caused me to ask more questions. Truly engaging content. So many great minds on this planet let’s give them a spotlight.
Am I the only one that noticed that these questions are so intelligent and well thought out, versus an American question that is like, “BRAH why can’t anyone be an astronaut?” Lol I do enjoy non English speaking professionals, and would love to see more like this!
Our minds are too simple to comprehend those answers in my opinion , we are scared of what we cannot understand , thats why we feel like that , and i share that same feeling its quite terrifying
15:38 I think there is a small translation error here where it says “pairs of matter and semi matter are created” late saying they collide and disappear. The correct term would be anti-matter as that is the only thing that when it comes into contact with regular matter would annihilate and become energy. It’s a small error but important to clarify.
There were a few other places too where translation seemed to lose something. I knew the things he was talking about, but some concepts might come over wrong if you don't. I suppose the translator wasn't familiar with all the concepts so they did their best.

I like how he didn't make fun of something fictional like warp or parallel worlds and just straight up explaining if it's possible or not, truly a man deserve some respects for doing so for others.
This is super cool that you guys brought someone who is non-American /English speaking person to do this. There are so many smart people who don't speak English.
This Q&A was awesome, I wish schools could operate at this level along with teaching the basics they are supposed to, so students don't have to rely on TV to have their simple questions answered :/
This questions were really good ones, no just dumb or silly ones, but serious wanting to learn questions 👏🏼👏🏼 love this one!

There’s a repeated confusion in the captions in English between _years_ and _light-years_ with expressions such as “light-years ago” and “light-years old.” In addition, the use of the word _space_ instead of _universe,_ or the reference to the Big Bang as “the beginning” of space and the beginning of the universe even though in the answer of one of the questions he said it isn’t known what happened before the Big Bang (and I’d add, or even if there was a “before”).
I get tripped out sometimes thinking about how without the universe there is literally nothing. I can't explain it but life and time itself would not exist
So not limited to humans. But life in general. However there are areas of deep space or micro scopic worlds that don't adhere to the same linear growth and growing principles. Leading to a sense of timelessness
@@MaxIronsThird the universe created seasons, humanity created the time minutes and houers. I have never seen a animal with a watch only humans do that. Time is just a invention for economicale efficiency.
@@stefan-ox8qs “the universe” created causality; A leads to B. For this to be true, time must exist, a medium for events to flow through. We named time, but we didn’t invent it, just like we didn’t invent space, despite animals never walking around with maps or like how we didn’t invent heat, despite animals never walking around with thermometers. Explaining, naming, “creating” the concept of something is not the same as creating the thing of which that concept is based upon.
3:43 i think there are some translation issues -- the solar system is a tiny part of the galaxy, so it the solar system = human body, the galaxy cant be "this earth (globe)" -- it would not even fit the proportions if he said "the earth" and refered to the actual planet we are on if the scale of comparison is
He didn't mean the actual size of the globe he was holding, he meant the size of the earth (that's why he mentioned how big a human would be as well)! So if the solar system was the size of a human on earth, the galaxy would be a couple of times bigger than earth. Does that make sense?
incidentally i can't speak for the accuracy of the fact itself as im not a science person but the translation of what he was saying is not inaccurate 😂
yeah, it's a poor translation. in his example, the solar system is the size that a human would be on his example earth, and the galaxy is several times the size of his example earth. Many orders of magnitude larger.
Normally if I clicked on a video that has a non-english speaker I would immediately click off as I don't want to read subtitles, but this gentleman held my attention with his cadence and expressions bringing what he was saying to life.
I love this guy. He has such a passion and energy about him that I can't help but be invested in whatever he is talking about, even though I need subtitles to understand him.
I don't know if something was lost in translation. What he is explaining at 14:05 is a wormhole. A warp-drive works by stretching and contracting space pulling a spaceship along as if it's riding on a wave. Warp drive may be possible in theory but would require a lot of energy, maybe even more energy than exists in the universe.
5:10 the "curvature" of space is a metaphorical denomination, in fact to be precise it is talked about the curvature of SPACETIME as one entity, and if you'ld span a huge triangle in the void there would be no curvature causing bigger angles since space itself is not on the surface of a sphere . . .
Год назад+2
I guess he used the example of a triangle on a curved/non-flat 2D space (the surface of the earth) as an analogy.
No, in this particular instance we're talking about the curvature of space, not spacetime (although spacetime is curved too). Here he's talking about the three possible ways that space (not spacetime) could curve; negative (open), zero (flat) or positive (closed) curvature. So yes, if you literally did make a large triangle in space, then assuming space isn't flat, you would indeed find that the angles didn't add up to 180 degrees. This is not because space is on "the surface of a sphere" (whatever you mean by that), but because the geometry is curved/non-Euclidean.
Yes, a passionate speaker - answering quite simple questions, but there is much more to know. I have been reading about astrophysics for decades - it is fascinating stuff. I encourage anybody to pick up some books on the subject.
OMG I love this guy. I had a few teachers like this, people who were truly passionate and enjoyed teaching their subject. I did well in those classes, because they could make their subject become fascinating stories that you wanted to follow so you didn't miss something important.
Fun fact about me: contemplating the lack of time & space that existed before the Big Bang is what made me realize that god couldn’t be real. I was 14 and was trying to imagine absolute nothingness. It actually broke my brain. To this day I get wildly uncomfortable trying to think about it. Also nothing can make you feel as small and insignificant as thinking about this as well as the age and size of the universe.
Funny how I had the same crisis and figured God did exist. The impossibility of the concept is so intricate and profound and how everything fell into place out of nothingness...I thought a higher being that's beyond our understanding must have been responsible. But to each their own, I guess.
That has nothing to do with theism. A motivation for theism is why we feel like there is reason in the first place. Many people use the same argument (of the lack of time and space) to justify a higher power. Just like an ant will never understand the scale of the earth, we likely are unable to understand the scale of the universe. Just like a blind person may not be able to understand the concept of sight, we may be unaware of certain existences (dimensions). In the end, if we are this small and still are able to feel happy/sad, isn't that good enough? Also, isn't it amazing that we are able to think about these things at all. These thoughts can be overwhelming, but that could be the cost of all the other wonderful things we can do with thought.
It's an uncomfortable thought because all you've known is existence. However the same concepts apply to life and death. Time and space don't exist, to you, before you're born, and after your die. Same concept here. That's said, neither is a good argument for or against God. There are many, MANY, better arguments though.
@@frenchconnection3640 there *isn't* design in everything though. And this has been disproven so many times it's actually almost comical at this point.
I think the person asking about warping of space was thinking in term of the concept of surfing a or creating a bubble in which to fly in. Warping space around a ship is a theoretical concept in which the fabric of space-time is manipulated to create a "bubble" around a spacecraft. This bubble would contract space in front of the ship and expand space behind it. As a result, the ship could move vast distances across the universe without actually moving through space. The ship would remain stationary inside the bubble, and the space-time warp would move the ship along with it. This concept is inspired by the idea of "warp drives" in science fiction and some theoretical physics research, but it's important to note that it remains speculative and hasn't been demonstrated experimentally.
The timing on this video coming out during my trip to Korea startled me. I thought I was getting Japanese media because of my location 😅 I didn’t know he was the feature for this episode. Always amazing content
I don't get how "space has a beginning" answers why don't stars fill the sky. Because they're not actually everywhere and if they're far away they're hard to see, no? Also I believe that most stuff not in our galaxy group would eventually disappear beyond observable range is known. I've thought matter slowlys turn to energy due to decay and entropy.
Год назад
Matter doesn’t disappear because of entropy. As for "decay," most of the matter in the universe isn’t made of unstable atoms or particles, and even those which are don’t disappear into nothingness. They turn into something else.
00:58 "Why is it dark at night". A question a child could ask. But it took humans CENTURIES to answer that question. It's called "Olbers's paradox". Kelvin, Kepler and even Edgar Allen Poe sparred with it. Many interesting video's on RUclips about why it's dark at night.
I had a question watching this video. If matter can not be created or destroyed, how was the big bang able to create so much matter? This might be a stupid question, but I wanted to ask it anyways
I'm not sure the translation is always top notch. At 9:26 he's talking about universes disappearing, as in, we don't detect them disappearing. Even if the many world theory were true, would we see another universe disappear? Maybe it's about galaxies disappearing? Around 14:30 WARP is mentioned, but what he's talking about is obviously a wormhole.
I wish I could understand japanese, the subtitles help with the comprehension but I'd love to be able to understand the energy and wisdom conveyed here, unfiltered!
Its not too hard if u really want to learn it. Its a pretty straightforward language. And yes its pretty unique this video even understanding a little.
You know what’s crazy. The question “ how do we know there was a big bang” He says that If we can see 13.8 billion light years away we would see the Big Bang happening every direction. That means that if you were at the Big Bang and looked also 13.8 billion light years away. Wouldn’t that mean that we were there since the very beginning.
@@munashemanamike4217 Do you really believe that the earth only have 3000 years old? Or that the cavemen or dinosaurs never existed? The bible is the world's dumbest theory of how humans were made, believe it or not
@@lenoirx but I wouldn't say it's the world's dumbest theory bro there are some wild cards out there like the Greek ones and Aztec ones and Hindu ones that have some insane Lore 💀
@@munashemanamike4217 Yeah, I can't argue that. Those are definitely dumb, but it's dumber that someone could believe in these things before they even make assumptions
The second answer should be because they are far apart.. it's odd that he mentions the "beginning" we have so many stars that their light reaches us but it's still dark. It would be much more informative if he mentions the "inverse square law"
Correction: At 15:38 and 15:41, the subtitle should read "Anti-matter"
it's clear this man loves what he knows and his profession. it's so cool to hear him talk

I had a question watching this video. If matter can not be created or destroyed, how was the big bang able to create so much matter? This might be a stupid question, but I wanted to ask it anyways
Matter isn't a constant, energy is. Matter is destroyed every second in the sun.
@@Spike00773 Thanks for explaining. Appreciate it!
I'm not sure the translation is always top notch. At 9:26 he's talking about universes disappearing, as in, we don't detect them disappearing. Even if the many world theory were true, would we see another universe disappear? Maybe it's about galaxies disappearing? Around 14:30 WARP is mentioned, but what he's talking about is obviously a wormhole.
I couldn't watch this while having my dinner so saving it for later cause I can't eat and watch out for the subtitles at the same time.
Excellent!!!
I wish I could understand japanese, the subtitles help with the comprehension but I'd love to be able to understand the energy and wisdom conveyed here, unfiltered!
Its not too hard if u really want to learn it. Its a pretty straightforward language. And yes its pretty unique this video even understanding a little.
You know what’s crazy. The question “ how do we know there was a big bang” He says that If we can see 13.8 billion light years away we would see the Big Bang happening every direction. That means that if you were at the Big Bang and looked also 13.8 billion light years away. Wouldn’t that mean that we were there since the very beginning.
I love him omg
That was fascinating
Bring him baaaack please
The Big Bang is the craziest theory to the birth of the universe. I just can’t fathom that that’s how all this was made
@@kelyaan8909 shoot, idk what it is, but every theory related to the birth of the universe is not able to be proven. Guess we just ain’t there yet
@@kelyaan8909 the Bible legit says almost the exact same thing. There was nothing and boom God made something
@@munashemanamike4217 Do you really believe that the earth only have 3000 years old? Or that the cavemen or dinosaurs never existed? The bible is the world's dumbest theory of how humans were made, believe it or not
@@lenoirx but I wouldn't say it's the world's dumbest theory bro there are some wild cards out there like the Greek ones and Aztec ones and Hindu ones that have some insane Lore 💀
@@munashemanamike4217 Yeah, I can't argue that. Those are definitely dumb, but it's dumber that someone could believe in these things before they even make assumptions
that red line on the big bang definitely seems like a radio-wave to me..
I’m glad so many people have the same questions I would ask.
i love this guy
Probably my favorite one yet
that was a great one. need more :D
The second answer should be because they are far apart.. it's odd that he mentions the "beginning" we have so many stars that their light reaches us but it's still dark. It would be much more informative if he mentions the "inverse square law"
i love these types of videos
Love it! Do another :D
15:53 lemonade stand analogy for non-state
Interesting video! :D
To see outside the universe, one must look within the self.
