Talk:2925: Earth Formation Site

The title text is only true for geocentric latitude and longitude, not geodetic (which is what is commonly used). 172.69.58.125 18:32, 26 April 2024 (UTC)

I'm impressed that whatever distant body that sign is placed upon, has actually developed plant life. Especially since it would need to be parked in place relative to the rest of the observable cosmos, & thus seems unlikely to have a suitably close star making regular appearance overhead...

Hi Proph! I just wanted to say that I enjoy reading your comments here and in the SMBC comment page, if you are in fact ProphetZarquon in both places. 172.70.175.28 21:46, 26 April 2024 (UTC)

If there's another Prophet Zarquon out there - wait, nope, looks like that's me, too...

The spatial location of a famous person's birth is technically not where the Solar System now is, also. If you're going to be picky about that. If you do allow the Earth's worldline to be accounted for, then it's broadly true that Earth formed (looks out of window at home) here. I think the principle concern there is whether Earth formed in the collision of planets named Ear and Theia, or whether Earth was Earth before Theia came along, which either way seems to be why there is such a large Moon beside it - made of material from both of the previous planets. And it probably counts as a change of course from the previous situation, although the apparent likelihood that Theia formed in Earth's orbit in originally a Trojan relationship may bear on that - if one planet just caught up with the other in orbit, like tailgating in traffic.

The ridiculously specific date may be a reference to how real historical markers frequently get dates incorrect 172.70.127.135 23:29, 26 April 2024 (UTC)

The other side of the sign says, "At this exact point in space, 13.7878693 billion years ago, the Big Bang took place." That's true of every point in space, according to the current model. The Big Bang implies that all of space was a single point, and space itself expanded outward from that point. Nitpicking (talk) 03:07, 27 April 2024 (UTC)

The explanation needs to be rewritten. It is missing the point and far to detailed for just saying: The marker could be standing at any point of earth's surface, as reinforced by the title text. The whole discussion about galaxies and solar systems moving is just a matter of the reference system and does not contribute to the understanding of the comic.--172.70.243.32 07:28, 27 April 2024 (UTC)

• I disagree. The section is saying that it could not have reasonably happened on Earth itself due to the fact the Earth and the Solar System itself move around through space. someone, i guess^{(talk i guess|le edit list)} 13:25, 27 April 2024 (UTC)

Randall was once a physicist. He's aware of the fact that there is no absolute system of measurements, and that locations on Earth are always relative to Earth coordinates, not some sort of galactic map. Nitpicking (talk) 14:10, 27 April 2024 (UTC)

Can the Earth's core even have a latitude and a longitude? Aren't those all referring to the surface? --162.158.90.198 11:47, 27 April 2024 (UTC)

You're right. That is the joke, in fact. Nitpicking (talk) 14:10, 27 April 2024 (UTC)
