The Fabric of Spacetime with Neil deGrasse Tyson – Cosmic Queries

What are your thoughts on string theory? Is it still worth trying to prove it, or should we refocus our efforts on other scientific questions?

😂Justin Wilson 😂
that's Cajun chef your imitating, not paul prudhomme
😅

Dunning-Krueger effect:
When someone thinks (erroneously) they are an expert

This ranger guy wasn't playing around

Justice for particles

I admire your show, I just wish you show more respect to the members of your community, like Profesor Brian Greene who is BRILLIANT scientist

Chuck: "I learned something new: I didn't know that about electrons!"
Neil: "I learned something new: I didn't know dense meant that"

1. How did the big bang begin?
2. A bunch of scientists attempted to replicate the big bang.
Goto 1

I wouldn't be surprised if all particles weren't entangled

Neil smashing is in emergant property on our macro level. Quite sure hadrons, do not go Smash. The question reveals the ignorance of the quote and the barrier of barrier of scientific explanatory jargon.

Regarding the weight of whales, he's right in the limit that while they're in the water, they have zero net weight. However, net weight is the sum of the forces acting on them, specifically gravity and buoyancy; since buoyancy acts opposite of gravity, this gives a lower net weight. Buoyancy is just the equivalent weight of water displaced by their bodies while gravity gives a measure of their mass. Normally, we measure weight as a means of determining how much matter is contained within a body, i.e. its mass; if this is what we're are after, then we must make the measurement out of the water so that the only force that is directly related to its mass is what we're measuring. Alternatively, we could measure its weight in the water and then add its buoyancy as determined by their volume, thus giving us its dry weight. Either way, it's the dry weight that's important to us.

This may be important for the whale since the density of water may change while the dry weight of the whale stays the same, or vice versa; a whale might find itself working harder to stay at a constant level in the water in such cases. Also, if a whale wishes to breach, it'll experience progressively less buoyancy the higher it is out of the water; if it does so completely, it now feels its full dry weight and zero buoyancy. This will affect how it must swim to accomplish this maneuver.

So particle accelerators are inducing particles to have particle babies.

I never thought of an electron as a particle that would have a size. I certainly never thought an election had mass. So... learn something new every day. Thank you! 😁

"Swell foop" ... (internal dialog) 'something is wrong here'

Degradation*

Sooo... is it fair to say there are particals that exist, in which the 'speed of light' is the LOWER limit? In which "faster than light travel " is an inevitability?

It's NOT an assumption to declare that there is a subset of "rules" (in reality, limitations) which govern all existence, at all levels... as Neil himself says, "the universe is under no obligation to make sense to you" your lack of conceptual faculty, is in no way a reflection of the primary truths of existence, within our particular space-time continuum

It's not Paul Prudhomme, it's Justin Wilson. Look him up, I gar-on-tee it!

Justin Wilson is the PBS chef with that iconic bayou accent. (Paul Prudhomme is a different Louisiana chef, also on PBS.)

I think that when the listener said "barbaric" he meant it in the sense of "primitive, crude, heavy-handed."
So it had nothing to do with the "feelings" of particles and whatnot.
❤ Love the show, y'all!" ❤

If our thinking speed aslo gets affected by gravity, then that means those scientists up there in the international space station will literally think faster than us? 😂 Or am i wrong?

I had no idea that we know so much about electrons, but don't know their size.... mind-blown

The big Bang was a big bully, just smashing everything around.

it was Justin Wilson you are thinking of

Justin Wilson is the chef!

Morons are dense because their brains are made of rock. Chemically speaking, I bet Neil could even prove that lol

This whole thing about particles not having feelings and being empowered to be a better particle is a Pixar movie waiting to happens

Considering the mass of the observable universe, the immense amount of the Energy at Big Bang Time, how does that transition into Mass? I am not an id10t, but I have a hard time with all of the known Universe starting as a dot from nowhere.

Ok, if time does not tick for light, what does it mean to say it covers 3 x 10^8 m every SECOND???

Chuck is Neil's dopamine😅😅😅😅😅😅😅😅😅😅he will always stay

That density discussion 😂😂😂😂

Michio has entered the chat

Hello Neil and chuck,

In relation to your point on string theory, you say there could be an alternatine that nobody has come up with yet, I have that theory. It is called the ' Two Monopole Particle Universe ' by ' Tony Norman Marsh. I am Happy to share it with you, if I had an email address that I could send you a copy of the hypothesis.
Alternatively, If you type Tony Norman Marsh into Google, details will come up and you could read the whole hypothesis on Kindle. Kind regards,

Tony Matsh.

Sometimes physics sounds like philosophy

In regard to the parallel lines question, I think it was asking about the notion that gravity is just a result of the curvature of spacetime warped by matter, i.e., is that warping of spacetime comparable to the way in which parallel lines meet on a sphere.

I am no expert, but the way I understood the concept I thought the answer here was yes, because from the perspective of the objects being attracted, they are moving in a straight line, but the curvature of spacetime means that straight line is curved toward the large mass, i.e. gravity and the appearance that an object is falling toward it. (Of course the word "falling" would be totally accurate because we use it to describe a consequence of gravity, but I say appears because "falling" doesn't really describe what is happening to cause it).

If I'm totally wrong someone please correct me and if possible explain what is wrong about that analogy, cause I'd like to know. Just here to learn.

How about the four musketeers of energy emission equations and then the the four musketeers of particulate phenomenon. Deep underground gold treated plates quantum particle experiments, cherenkov how's it going. Also not occilations but one of the puzzle pieces from the incompleted Steven Hawking imagine the master of disguise masking plus ace ventura hey there and the siamese cat ... Umm one sec umm hold it breathe okay mystery detector prism reflection from the dut dut dut duuuut

Did he say at 43.30 that 4th dimension is time? Neil previously explained that the 4th dimension is made of cubes... how did he get to it being time?

At 8.17 neil gives the information that explains God in todays terminology... two words... know and believe.
Believe means .... the opposite of know....
Believers of God... don't know if god exists.... knowing is provable and Believe is just a thought... according to our use of languages.... quick fact.... the universal language of the universe is not english.... or any other earth languages....

Space time exists in a physical medium.... the physical universe that we measure... the mind thinks ... and our thoughts and ideas exist in a non physical medium... maybe called spirituality....or telepathically existing...or some kind of quantum physics... that may be some variation of science in this non physical medium that we have yet to understand...

Hey, according to Einstein, if the mass of a photon is Zero, then it has Zero Energy, and that's not true, or we would not have Solar Power. So, a photon Cannot have Zero Mass... So...? 🙂‍↕️🧐🤔😳🤯🤓

I may be wrong here but I think what that first guy meant was that our means of observing the very small seems analogous to us taking a hammer to a radio to study its electronics. Might there exist a means to study the very small without taking it apart is what I think he means. 😅

M bass W hight T t highT? Mbass

Boombag goombaa ss ssss sss gombass

How different could a massive group of stars, black holes, and planets be to exist in a place where normal ones do? Would be interesting if a big bang happened inside a universe with existing galaxies. Probably an unlikely scenario. Unless the JW telescope is peering through a wormhole. I guess I’m not betting on the BB. You’re young enough Neil that you’ll see it disproven lol.

This just screams 3 dimensional time because it is all relative. Time relative to what? Proven, good! Think...

so wait? heres a riddle. A man in the forest smashed two hammers together, did the hammers feeling get hurt?

So if we leave out solar system how much does time slow down because there is less gravity effecting time?

Okay this makes me feel a lot worse about people in the know actually being in the know because it has been extremely well known about spin launch for several years now like I think I heard about them shortly after they were created
