Joe was asking how that could make sense because we know the universe has depth. The guy diverged on his explanation and started to answer the wrong question. His explanation started out right in saying that he's only talking about 2 dimensions, but could've continued in saying that basically if the universe is a box, then the top is flat. Instead he went into angles and shit that wasn't exactly where Joe was lacking in understanding.

Rogen is asking perfectly reasonable question. I am a PhD student, and it took me some time to wrap my head around what cox is saying when I first took a GR course.

[@JokerScribe]

His 'explanation' of 'you can see the big bang light from 13.8 billion light years away' is really questionable. That would imply that earth travelled faster than light to reach where we are. Almost 13.8 billion times faster than light to get to where we currently are and then at some point it slowed to let light catch up. If his explanation of seeing the big bang light is true. No amount of gaslighting or BS or ad hominem attacks can fix the fact that his 'logic' here is flawed. Even if it takes into account that light would continue to pass us for almost 13.8 billion years, meaning that the universe would have to be much older than they give. Also, there not seeing the big bang light, that's way way ahead of the physical universe now. What he means I think is that we're seeing 13.8 year in the past, at an earlier universe which now has to be older than that to take in consideration why we're so far away when the universe was allegedly very young.

[@JDG.RealEstate]

Can you help us understand? It doesn’t make any sense to me. If we can see as far as 13.8 billion light years in any direction, how can we be in a flat universe?

[@johannsebastianbach3411]

@@JDG.RealEstateflat in this sense is only a mathematical concept.. to us mere humans flatness only makes sense in 2d. Which is what cox is trying to convey. Like, after a certain point you cannot visualize as a human, and just use math as the stick that a blind man uses to see around. The math that we use suggests different 4 dimensional geometries, and I guess when you draw a 4 dimensional triangle and add up the inner angles it adds up to 180 degrees or whatever mathematically in our universe 😂 Just linear algebra after a certain point. That’s not the frightening part for me tho. The frightening part for me is this: All physics theorems were eventually conjured up by people with great imagination and visualizations: kepler, galileo, newton, einstein etc. And we are bound to visualizing in 3d since we’re humans. Newtons theorems worked well for us and explained most stuff that we cared about, since we only cared about constructing buildings and trains and cars and planes… when we started to think about far away galaxies, that’s when newtons laws failed, and that’s why einstein had the guts to sit down and imagine what could be happening really (since the old laws demonstrably failed) But imagine this, how could any human in the future could even start imagining a replacement to general relativity if in order to come up with one, one might need to be able to visualize in 4d 😂 if say GR fails some explaining some 4d phenomena, how could we even observe and demonstrate that it fails, let alone allowing someone like einstein in the future to start imagining what really is going on… dunno… i have work tomorrow so i don’t care after a point 😂

What he means by flat is like saying the surface of the earth is flat. If you look at earth as a whole it is like a sphere, but the surface of your observable earth is flat. So we can only see so much of the surface of the universe, not the whole universe in one go.

[@ezchoice28]

It's just a matter of geometry according to our best measurements to date. Simply put that any triangle, to the furthest reaches of observation, will add up to 180 degrees. If there was curvature you would not get this measurement. What he is saying is that this likely means that the universe is a lot bigger than what we see. There is a chance with more advanced measurement, with better technology, a curved surface may be detected (he is not saying it will be detected either). At this point, the universe seems flat in all directions in terms of geometry.

[@BreezyFknDoesIt]

@@ezchoice28 thank you I actually understand now 👌

[@squall86drk]

The problem with Coxs explanation is that he does not explain that we are not referring to flat as a 2 dinensional feature, but as a 3 dimensional feature. Joe is thinking that the whole universe is a infinitely large board, but thats obviously not the case. The other example he could have done with curvature was taking a sphere (a soccer ball for example) and compare it with a desk surface and trace on both object 3 lines of the same lenght, each one connected by the next one by a 90° degrees angle. On the desk surface it will end up as an open shape (like a square missing one side) while on the sphere it will end up as a triangle (closed shape). Same dimostration is usually presented to debunk flat earther.

[@shantanoob]

Man that explanation was sooo good! Bit strange to see so many folks in comments not understand and enjoy that. I thought it was great.

Think of the trajectory of light in space, if it finds no obstacle on its path and no massive object to change it, its trajectory will be a straight line. This is the meaning of flat in this context. If light was curved even if there's no physical interaction to deviate it, we could say that te universe is not flat because it would have what we call a positive or negative curvature in that case.

I have to admit, it’s a difficult subject but if you take into account everything Brian was saying, he is actually answering Joe question fully and beyond. The subtle of the answer and the question make you ponder beyond your brain can handle. it’s a single slice of the universe of zero thickness (or plank thickness if you will) expanded to infinite. That slice is our present time at every moment and it is flat, not curved, but flat, b/c mathematics shows it flat. Brian went on and did a beautiful demonstration of how math can prove something flat by the total angles of a triangle or pi value of a circle on a flat vs curve surface.

[@obsidianman50]

For those that are confused, think about it this way; If you were to send a beam of light from the edge of the observable universe to Earth, it would travel in a straight line except for when it curves slightly around objects like stars due to gravity. That is how we can tell space alone (ignoring gravitational influence ) is flat. Further optional explanation: However, this would mean that the universe doesn’t curve around on itself, and would imply that beyond the observable edge, the universe continues infinitely. What Cox is saying though, is it is like ants trying to determine whether the earth is flat, from the ants perspective of a tiny portion of Earth, they would think that earth is flat, and If an ant rolled a ball (rolling a ball on the material surface of earth is equivalent to sending a beam of light through space time) from the edge of the area in which it spends its entire life (quite small) then the ball would go in a straight line, but if you tried to do that from London to Tokyo for example, the ball would roll around the curvature of the earth, figuratively speaking. The universe is potentially the same, the space time fabric itself may curve on a massive scale that we can’t comprehend, so that theoretically eventually a beam of light going in one direction would end up at the same place. But that would take longer atleast than the current age of the universe

[@christopherd.0356]

Flat universe means that if you beam two parallel laser lights, the will neither meet or part no matter low long they will be travelling. This is a proof that space/time does not bend/curve. Scientists do not refer to the spherical observable universe (it is a sphere because we can see in every direction and that makes the observable universe a sphere out of which we have no idea what it exists), but to the actual fabric of space/time. That is why he speaks in two dimensions..to simplify. For example space/time does significantly curve/bend around masses as planets, stars, black holes and galaxies - which is what we perceive as "gravity" - but it does not curve/bend in a grand scale. On the other hand, since we can only observe that much, we can not know for sure of the actual shape of space/time outside of the observable universe. As for the negative comments about Brian Cox, due to lack of astrophysics' knowledge on behalf of the commentators, I will quote Carl Sagan: "The Universe is not obliged to conform to what we consider comfortable or plausible".

[@lunarrover24]

Here is a simple explanation of flatness. You are floating in space but can walk in any direction in 3d. 0. Mark your starting position. 1. Draw a small line segment, maybe 1 mm small in any direction starrting from where u are. 2. Goto the end of that line segment. Draw another one, make sure the angle between the previous one and next one is 0. 3. Keep doing this forever. If at any point you are closer to starting point than the sum of all segments, the space is negatively curved. If at any point you are farther than the sum og all segments, the space has positive curvature. You only need one dimension, but potentially infinite time to prove this depending on the curvature. Physicists use light from distant galaxies to measure curvature and as far away and back we can see, barring for local gravitational lensing effects. Space is flat.

@@natashagoode501 you completely missed the point. from where you are standing in your house the world appears to be on a flat plain . from outside the world you can see that it is a globe. the same concept exists for space as a whole.

[@minhfam]

@@Google_Does_Evil_Now When we say flat universe we don't mean it's like a flat sheet of paper. It means it has zero curvature. We can also have positive or negative curvature. The easiest way to imagine this is if you have 2 parallel lines (at your frame of reference): - 0 curvature (flat): the lines will always be parallel to each other. - positive curvature: the lines will converge (think of longitude lines all converge at the poles on Earth) - negative curvature: the lines will diverge (hyperbolic space but it's harder to imagine) Independent sources have confirmed our observable universe to be flat (with a small margin of error). But the global universe is a much tougher question.

[@Google_Does_Evil_Now]

@@minhfam why didn't he just say that in every direction it goes in a straight line. Flat implies flat. And he didn't say flat in any plane, any vector, any direction.

[@oldmusician5236]

If it's true on Earth, then yes. If we assume that both animals take the same amount of time - and are equally able - to adjust to the new environment, then Newton's 2nd law tells us that the force needed to produce a given acceleration is related to its mass. This is observed in space when astronauts have to move objects with a large mass. Their very mass (even with zero weight!) makes them harder to move. So if the power to mass ratio is the deciding factor, it will be the same in zero gravity.

Perhaps I can help... Imagine that you send 2 space ships on a mission in space. They start one mile apart, and have the exact same angle (vector). After 1 year of travel, assuming they travel at the same speed, and assuming they only travel through space without spatial interference (gravity), they will still be 1 mile apart. But why? Why don't their lines of travel intersect or diverge? Why is a straight line in one place consistently perpendicular to another line with the same starting angle? On the surface of a sphere, this is not the case. Why would space be flat and not spherical, or some other shape? Why can't you travel 1,000,000 miles in a direction and arrive back where you started? You can do this on a sphere or a mobius strip and on many other surfaces. We take this property of space for granted, but scientists do not. There isn't a particularly good reason that this should be so. I think this idea is purposefully misconstrued to confuse people. He is not saying that 3 dimensional space is a 2-dimensional plane, he's saying 3 dimensional space is flat like a 2 dimensional sheet of paper can be flat - provided it is on an even surface. The number of dimensions is irrelevant. If you put 2 bugs on an ice cream cone, they might start in different places, both walk in the same "direction" on the cone, but still eventually meet. In truth, the very concept of "walking in the same direction" requires existence on a flat plane, regardless of how many there are (1,2,3,4 planes)

That is a really good explanation, thank you

[@HackingAxe]

I agree this is a really good explanation.

When physicist talk about shape, they are talking about how is gravity distorting and bending space. The universe could be infinite and their a few ways the distortions of gravity can have this happen. There are also distortions that mean that the universe is finite (not infinite). So, you can have "shape" with or without edges. "Flat" means that the space is really boring (regular space that we are familiar with). Around a black hole space is really distorted, so not at all "flat". When they say the university is "flat", they mean that over HUGE distances, on average, the distortions of gravity end up being boring; it's just regular space, it is not distorted on any large scales. Using the word "flat" is a bad choice when trying to explain these things to people that have not done many years of hard maths. For people that have done all that maths, it makes a lot of sense.
