One thing that has always puzzled me is that the farther we look out into the universe we see that galaxies are moving away from us faster than galaxies that are closer to us, but also the farther we look out into space the farther back in time we are observing. I have trouble understanding...

Thank you PeterDonis that makes very good sense.

It seems that the discussion has gone way off topic although very interesting. I would be very appreciative of a straight forward answer to the question at hand which is this I want to understand why the farther and farther out we look we observe that objects are moving faster and faster and...

By measuring over time do you mean that we only take a series of measurements of an object to determine its velocity or do we also take a series of measurements while also taking into account that the light that we collect left the object x number of years ago and the rate at which the object is...

Thank you for these very good answers. I have always felt that it is best to never assume anything and to question everything. Looking at this in terms of what objects are doing relative to each other rather than measuring their distances and speed from us makes sense. This is a link to...

Please forgive my lack of knowledge about the more complex ways that we have determined that the rate at which the universe is expanding is increasing, but one thing puzzles me. I have read that based on measurements of the red shift of light we have concluded that the farther we look out into...

Thank you for the response and for watching my video. I read that article before posting this video and searched through images of diffraction grating and did not see much that resembled the same pattern as I was getting here. In most of the examples that you see it is light passing through a...

OK so before I begin I will ask that you forgive me because I do not have a working knowledge of the mathematics involved here and I am admittedly not even at a novice level of understanding these things. However I have done at least some research and understand how an interference pattern does...

Please excuse my astronomical lack of knowledge on these two subjects. Pun intended. The two seem to be somewhat similar. Einsteins model of gravity describes space time as a fabric but it seemed to be easier for me to visualize if the properties of space time were more like a fluid and the...

Thank you I will definitely do that in the future.

Yea that would be me. And thank you. Naty1 Thank you for the feedback and my apologies for the very simple breakdown of this idea. It was something that I thought of standing in my driveway this morning and kind of rushed to jot it down as to not lose it later. Thank you for the links...

A hypothesis only by James Leckner Looking at space as a form of energy itself or as another way that energy is converted from one form to another. You would look at space as not the result of a large explosion (per say) but more like the conversion of one form of energy to another or even...

Ok i totally get this now. Thank you so much Marcus. Just doing a search, after reading your response, on the diameter of the observable universe tells you a diameter of 93 billion light years. Really cool stuff. Thank you for the link to that chart too that is super helpful.

Ok thank you. I am still curious about the current position of this far off object vs the position that we observe it at based on the light that has traveled from it. Here is kinda where i am confused. We observe that the farthest galaxy from us is about 13.3 billion light years away...

Thank you. I did think that we were using redshift measurements to infer or confirm that the universe is in fact expanding (similar to the doplar effect) but was not aware that this was telling us anything about the universes age. Am I wrong in thinking that we observe light from the...
