Where Is The Center of The Universe?

Duh, it is at (0,0,0) obviously. I'll have that Nobel prize now.

Nobody has ever made me feel more passionate about things I can’t remotely understand than Matt.

"If you can't explain it simply, you don't understand it well enough". If that quote is true, then no one who has explained it to me understands it well enough.

After about 2 years of trying to properly understand this topic, this is the video that finally made it click for me. Excellent job!

The explanation of how 2d person can point anywhere and be pointing at the center of the universe and it's applicability to a 3d universe was sublime. Thank you. I understood it.

I consider myself pretty well versed for an amateur who has only taken a half dozen classes on Astronomy, but the material on PBS SpaceTime is way beyond me. And I love it.

Love this guy. You know new possibilities will be discovered listening to him because he says "But, I'm not sure" fairly regularly. Sometimes I have to watch an episode twice (unavoidable since he goes a bit beyond a documentary for us average brains). I think I've watched all of them since they started !

So, along with the 2D surface on a sphere analogy, would that also mean that sending two ships in opposite directions, approaching the speed of light, that they might run into each other again at the "opposite side" of our universe? Or maybe we could look in two different directions and see the same ancient star?

I love this show so much. Thank you Matt ands PBS and everyone who helps make this real. I'm having a kid and I can't wait for the day that I start watching the whole back catalogue of Space Time with him.

Love these segments both questioning and reaffirming assumptions, leading to a deeper understanding

The reason why this is the best physics channel is that every other channel would simply put out a video explaining that there is no center. The same old stuff. When this channel asks a question, even if it's a "basic" one, I know I'm going to learn a ton.

I have never been helped this much with the geometry of the cosmos. Now one of my all time favorite videos! Thank you so much 🥰

If "closed", "open", or "flat" applies to the spatial shape of a universe, would that in any way also apply to its temporal shape? That is, would a spatially finite "closed" universe eventually and necessarily recollapse? Would a spatially infinite "open" universe necessarily expand forever? Would the expansion rate of a spatially infinite "flat" universe necessarily approach zero? Or are these entirely different properties?

You can take simple questions, explore topics I'm sure I've heard plenty about and yet you always manage to give me new insights. I love it!

A problem that keeps coming up IMO is that when we talk about all these ideas about ST we use a 'zoom' function in a very similar way as when we take a picture here on earth. What if zooming in and out on any scale (microscopes and/or very macro scales) is similar to how we used to think about size of universe (obviously its contracting because matter is inside and at some point the gravitational pull brings all matter back towards each other - wrong) so what if the way we conceptualize the zoom function regarding edge of universe shape of universe multiverse etc cant be zoomed so simply. What if there is a nonlinear [zoom constraint] of sorts....it would change our interpretations and assumptions from, and could unlock another piece of the puzzle to what is shape/what does it tell us... in a time dimensional blob? 'Zooming' needs to be put under a microscope!

You should do an episode on Chirality versus Helicity! The whole the imaginary number line is fundamental to how the universe works is just wild to me, I would love to hear your explanation

Finally, now I can point people at this video for the answer.

Great subject and amazing episode, as always Any chance that the Euclid mission could help getting closer to an answer?

If every one of infinite points is equidistant from every other point, that would mean that every point in the universe is the center of the universe, so, technically, I am the center of the universe. You may bow.

Here's a fun one: Next time you go out for a walk, imagine you're still located in the same place, you're just using your feet to scroll the world under you instead. Theoretically this perspective is also correct since everything is relative. So yes, we may be at the center of the universe if that center is the point of our perception.
