On behalf of Earth, I have to ask all those galaxies moving away from us: โIs it something we said?โ
-
Improving knowledge is getting better, not "worse". It is not a "big problem". In the future things that are taken for granted today might be proven to be mistakes tomorrow; that is science.
-
Moments like these are the most exciting moments in science.
-
You know what is interesting? All the debates and competing views were completed without anyone being burned at the stake or condemned as a heretic.
-
I'm expanding way faster than the universe!
-
There is no crisis in cosmology. We are advancing our insight. Its progress. The laws we handle in science are the best we have.......untill we learn otherwise. That is why agnosticism is the best attitude. (also socially)
-
Mind officially blown! Webb's findings on the universe's expansion are mind-boggling.
-
Except for our current assumptions this is hardly a โcrisisโ or a โproblemโ. Itโs science and itโs a wonderful and exciting question. This is how science works, by following the facts wherever they may lead.
-
We don't know didly!
-
Seems like the more we learn, the less we know.
-
There is no crisis. And it's not a problem. It's impossible to measure the size of the universe because it keeps expanding everytime human consciousness focus on it!! This is just the way it is!!
-
What if physical constants are not constant over long time?
-
My waist keeps expanding.
-
I know I'll be laying awake all night worrying about this crisis!!
-
The one thing I've always really admired about the entire field of astronomy is that they're not afraid of new discoveries and are more then willing to acknowledge that changes are needed; unlike archeologists and historians who are willing to go as far as to hide or destroy new discoveries that might affect the status quo.
-
Thought provoking!! If there's a missing link( which seems plausible after the discrepancies found between two measurements) I hope it will lead the field of Physics and Astronomy to a greater understanding of this existence. A well analysed episode it is!! ๐ฏ๐๐
-
Excellent presentation. Am I right to understand that the rate of expansion, though obviously very important, is really quite slow compared to cosmic distances and velocities? Or am I missing something?
-
According to The Urantia Book, space respiration is the pulsating nature of the universe, which takes place in billion-year cycles. Each phase of space respiration lasts a little over one billion earth years, with one phase being a billion years of expansion and the other a billion years of contraction. The book says that we are currently halfway through a phase of expansion. So no big problem
-
I am happy to see you start to make videos again SOU
-
The thing I really like about SOU is that their contentjust keeps getting better and better. I have been watching your videos for the past three years now, and this was the best one so far. The animations, script, narration by Jeffrey, and presentation was top notch! Please keep it up. Looking forward to more :)
