I had a Follow Up Query regarding this Question of The Week.QotW - 21.09.13 - Where does the extra energy go when light is stretched?
Quote from: Zer0 on 15/10/2021 19:34:54But what if that same Space Contracts somehow...then Does the Light/Energy Re-emerge from the Darkness?Expanding space will red shift (stretch) photons wavelength. Contracting space would blueshift (compress) photons
But what if that same Space Contracts somehow...then Does the Light/Energy Re-emerge from the Darkness?
There isn't any extra energy I know of , can you please explain more of what you mean by extra energy ?
Space being independent of space-time is an oxymoron. Space-time contains space. Space is the only component of space-time that can expand, as time doesn't have a size. It doesn't make sense for something without a size to expand.
Hi @Black hole, I've not seen you before so..... Hi ! and I hope you are well etc.Quote from: Black hole on 15/10/2021 20:15:34There isn't any extra energy I know of , can you please explain more of what you mean by extra energy ? The OP (Zer0) was posting a question that is a follow up to this podcast:https://www.thenakedscientists.com/sites/default/files/media/podcasts/episodes/Naked_Scientists_QotW_21.09.13.mp3Which is also discussed in this thread:https://www.thenakedscientists.com/forum/index.php?topic=83011.0 Those should help to set the background.Best Wishes.
Space-time, by the very definition of what it is, contains space.You're a physicist? Where did you get your degree from? What company do you work for?
I do not answer irrelevant questions prying into my identity , thanks for understanding .
by space it means distance , not the actual space
QuoteDistance is what space is. Distance isn't what space is , distance is an unspecified measure i.e That chair is a distance away Space is a vast expanse that is occupied by matter relative to our visual boundaries and knowledge so far . Beyond the space we can visual observe may be empty space , void of all matter . I was hoping this forum wouldn't leave me knocking on empty doors for discussion but you don't seem to understand the difference between space and space-time . I hope you understand now after my effort to explain to you ? This is a very common mistake to make and most people make this mistake when trying to understand Einsteins work !

Sorry but I am a physicist
Space: "the dimensions of height, depth, and width within which all things exist and move."
@Black hole Stop posting about your alternative views in the main section of the forum. Keep it in "New Theories". You have already been warned about this.
What alternative view ?
A person will also give the wrong answers if their own understanding is not quite on par to understanding some of the more intricate details .
I'd be happy to take up definitions with you in a just chat thread if you'd like to continue to debate about definitions and understanding of those definitions
