As much as I'm all for metric and would rather have lenght in meters and not feet, i dont think there is a problem of mixing in this context since one is a measure of lenght and the other a measure of time

@@DanteKG. I'm not an expert on imperial measures, but I'm pretty sure that they include "seconds" among them. It was a joke. Furthermore, all imperial units are now defined in terms of metric ones, so there isn't really a problem anymore; imperial IS metric.

A fortnight is a ridiculous number of orders of magnitude larger than a nanosecond. You want a femtofortnight. It's equivalent to 1.2 nanoseconds.

@@tparadox88 I originally wrote "picofortnight" but changed it because metricizing the unit like that muddied the joke. I now think the correct angle would have been to make fun of the fractional units that Imperial technicians frequently use; metric is decimal and imperial is not. So it would be something like, "feet per sixteenth fortnight"

Yes.

Also it was in a sort of poem form and I will concede that the imperial units are far more poetic

From my very limited understanding, no, we can't determine our location. The horizon on our vision is a result of light taking a set time to travel a set distance (constant speed), not a problem of distance alone. A property of seeing light from far away sources is that we see what it was like a long time ago, but if we were in a different spot in the universe (theoretically) we would just see different stars/galaxies surrounding us until our ability to see further fell off. Essentially every point in the universe is moving away from every other point at an accelerating rate. Think of drawing 4 dots on a rubber band with the same spacing -- if you pin down the band in the left-most spot and stretch the band right, the distance between each dot doesn't stay the same. The further away the dot starts out, the more distance they will stretch apart with the same amount of pulling. That's kind of how the universe expansion works and why at a certain distance, not even light can overcome the speed at which the points are moving apart because, as we've known for ~100+ years, lights speed is constant. I think most physicists (at least from what I've read) don't believe there's an actual center, space just seems to be moving apart everywhere. No matter where you are the effect is a horizon that we can never surpass because even if we were traveling light speed (which is theoretically impossible, but even if it WERE possible) the expansion would be to great to overcome and the horizon would stretch away from us exactly as fast as we traveled at it (at some point). I think we can use the microwave background radiation to determine our speed/direction through the universe to some extent. Because the microwave background radiation should be roughly the same in all directions, if we're moving towards the light or away from the light it will become slightly blueshifted in one direction and redshifted in another, which I think we can detect and measure. This is the same effect of sirens sounding high pitched as an ambulance drives towards you then the pitch changing to a 'weeEEEEEOOOOoooo' lower pitch as it drives by and away.

The universe is possibly/probably infinite. So no matter where you are, upon looking the "age of the universe" in light years away from your current position, you will see a shell of fire equidistant from you in all directions. Simply because that is what every point in the universe looked like at that time, and you can't see light older than that.

Donar, It's actually the same distance all around. But not because we are in the centre of the universe. Because we are at the centre of our own perception (just as is everybody else). The big bang happened x time ago so it appears x times c away where ever you are in the universe. The place where we see that "ring of fire" if we were there now. It would not be a ring of fire any more, that was billions and billions of years ago it would look like normal space. But then if we looked back at the earth, we would see it as it was at the beginning of time and, yep, you got it, it would be the "ring of fire" for that's perspective.

Donar, I share your doubt. If the background radiation looks the same from everywhere in the universe, then it would be infinite in mass, wouldn’t it!?!

The centre of tge universe does not exists. Ot was an explosion of space not "in" space.

They’re called imperial units.

@@kirkhamandy Not true, IMHO, it's called accessibility. It's better for some people to have US Units. In such videos, though, both numbers should be displayed so people can gradually get used to SI/metric

@@ChaineYTXF Check the video; she said 1 foot, but it showed "30 cm"

Join our Cult! We believe, that we live on a flat side of Earth. Its volume is measured in cubic feet, then it's a giant cubic FOOT in a Vacuum! We never touch Spheres! Sphere is a Foot of The Devil in our realm! Destroy all Spheres!

Who ever said volume is measured in cubic feet? You can measure the volume in a cubic foot but, volume is not measured in cubic feet.

She is spaceballs

Its not outdated here in the us and im gonna guess that the people making these vids could be in the US

She defined a foot both as 30 cm (the ruler in the video) and as a potential distance between your hand and your face. There's no need to be obtuse, you have SOME idea of what that means. Even if you only listened to the audio, you could infer that a foot is something more than 0cm and less than your arm's length which is close enough for the general example she used it for. You've obviously heard of inches and feet before, even if you don't know how long they are, since you say they're outdated.The thing I have no idea about is why half the comment section is about how she dared to use the word foot in the video and not... you know... literally ANYTHING else about the video that was more interesting.

He even showed 30 cm in the video, and then an image of a person holding their hand about 1 foot in front of their face. Seriously, people need to get over themselves. It's not like he was actually measuring something, it was an offhand comment that rounded to the nearest applicable unit. He could have said 30cm, but a foot is simpler. "This is a metric channel not an imperial channel!!!" ... no, *it's an education channel, get over yourselves.*

One Foot is our God! We believe, that we live on a flat side of Earth. Its volume is measured in cubic feet, then it's a giant cubic FOOT in a Vacuum! Let's pray to One Foot! And destroy spheres! Lick your Feet! Pray to The Giant Space Foot, The Almighty One Foot!

maybe we can see beyond but there is nothing there to see... thought about that?^^

Yep, it would be nothing at all but that would require having something able to see absolutely nothing, I mean, eventually you would end up seeing energy so concentrated that it would look like a blob of sheer light. To see past it - and past the big bang itself - we would need a piece of technology so far beyond our comprehension it could reasonably be called "The Eye of God".

The other way around. If you see a wall - it is finite. If you don't (or see beyond) - it is infinite.

I think that's one of the goals of the James Webb Space Telescope. To get more information from that era, since it can see in infrared, and infrared traveled far better across that dense cloud of dust.

Looking beyond big bang is about the same as going further north from the north pole. There is no further north from the north pole, as there is no time or space to see beyond the big bang.

The blue shell destroyes everything

The fact you had to explain the joke destroyed it

I know you're joking, but you understand that there was no red shell. The big bang is a single point, not a shell. It appears as a shell because of the speed of light but it was a single point.

Running was invented by Thomas Running in 1862 when he tried to walk twice at the same time.

I’m ashamed to admit that it took me reading the rest of the thread to get the joke.

Except "causality" (cause->effect) does not imply "simultaneity" (t_A=t_B). Let's say a star blows 10 Glyr away (and, for simplicity, spacetime is Minkowski): then, it takes 10 Gyr for a photon that was just outside the star to reach us - in which case, there's nothing wrong in saying "we're seeing a star that blew up 10 Gyr ago". The problem here is that we, as observers, are "married" to a "preferred" frame - namely, the one we're at rest WRT -, which masks the fact that relativity itself doesn't care about which frame you measure things with; the "10 Gyr ago" figure refers to our preferred frame - if we change to a boosted frame, that figure changes, and that's all there is to it

Iago Silva It depends on your perspective. Causality is just a very simple relationship between 2 points, and time is not part of this equation at all, because NOTHING happens with the particle between the 2 points. From the photon’s point of view, it is in fact simultaneous. I agree with the rest what you said.

@@juzoli "It depends on your perspective" is just saying "It depends on your reference frame"; causality is just the well-orderedness of events: if you think of a sequence A->B->C->D as a pearl necklace, no matter how you twist it, the order of the pearls is maintained. The fact time isn't part of the equation isn't because "nothing happens in-between pearls" - it's because the time that we read off each ref frame simply corresponds to a different way of bookkeping the pearls as you twist the necklace. I propose causality is a _topological property_ - I seem to be in good company: *Roger Penrose - _Techniques of Differential Topology in Relativity_ ; *S. W. Hawking, A. R. King, P. J. McCarthy, J. Math. Phys., 1976, 17 (2), 174-181; *E. C. Zeeman, J. Math. Phys., 1964, 5 (4), 490-493; *E. C. Zeeman, Topology, 1967, 6 (2), 161-170

Iago Silva “Nothing happens” means nothing happens with the photon/particle itself. It doesn’t have any interaction, so it knows nothing about the rest of the universe. Time itself only comes into the picture, when we are trying to place this single cause-effect in the grand scheme of all other causes and effects, aka pearls. And yes, this is just another frame of reference I’m proposing. And I believe it is better, because it is based on a more fundamental universal constant: C, and it is also closer to what we observe. Currently the difference in time between what I see as a star (past) and what I believe the star is now (present) depends on the value of C. In the new frame of reference we can simplify it, and leave C out of the equation. Again, nothing is actually wrong with the current one either, both model reflects the reality, I just believe the current one is less useful, and ignites unnecessary arguments.

Thank you for your insight!

But now has been discussed like a million and one times, which hasn't been done before - so there you have it XP

None of their videos adds anything new. This channel talks about what is known about our universe in a concise way. In addition, this discussion was poem-like, so it added a nice twist to what "has been discussed like a million times already"

My point is that most of the videos here teach you something interesting that you might not have known. This one felt like it will tell you something about the very edges of the universe, but right after it explains the basic stuff about CMB, it just stops. Rvery other educational video explains CMB very briefly, yet with the same effect, to talk about something more advanced that is connected to it. Here it just discontinues an interesting conversation after 2 minites.
