Reply to Does the age of the universe depends on where you are? by _bidooflr_

The thing I've never understood is "we're looking at the first light after the big bang" this is what they say every time we look deeper into space. If this light is just now hitting us and it's 13 some odd billion years old. How the hell did we get here before the light after the big bang. So whatever light we're seeing is actually NOT the first light after the big bang. Not by a long shot or am I overthinking this?

Yes because space is time and time is space, they are interconnected. Also at the same time no because boundary conditions are relative to a point of origin or reference. So more specifically which age of the universe you are in depends on the location you exist at however that age stays the same size regardless of where you are.

Reply to What happens at the end of a subduction zone? When the entire plate subducts? by kittens0423

Look at the geography of the western United States because that is exactly what happened. The Farallon plate was subducted under the north American plate a couple million years ago. The rift zone from the Farallon plate is actually stretching the continental crust of the North american plate creating features such as the Baisin and Range, Colorado Plateau, or even possibly the Yellowstone volcanic chain.
