AI Thread Summary
Recent measurements of the universe using the Hubble Space Telescope are raising questions among physicists, particularly regarding the nature of space, which may be smoother than previously thought. The discussion highlights the ongoing challenges in understanding quantum gravity, with participants expressing a desire for a resolution to this complex issue. The article referenced suggests that further research is needed to clarify these findings. One theory posits that time and space could vary together at the Planck scale, potentially preserving the formation of starlight beams. Another explanation involves the concept of Planck length squared, indicating that the observed variations might be extremely subtle. Overall, the conversation reflects a mix of curiosity and humor about the complexities of theoretical physics.

Interesting article, thanks.
As the article says, there's still much work to be done and still much that is not understood.
Can someone here please complete the theory of quantum gravity? I'd like this resolved soon, please. :wink:
 
I've correctly completed the theory of quantum gravity years ago. It was a subset of my Theory Of Everything. I'd post it here, but my dog at my notes. :wink:
You'd be surprised at how much everything depends upon the existence of blue orangutans.
 
The last paragraph of the article speaks well to possible explanations for the phenomenon within discrete theory:
One is that time and space might vary together at the Planck scale, keeping beams of starlight in their original formation. The other is that the wobbles might reflect the Planck length squared - about 10-60 metres [squared] - making the smearing undetectably small.
 
This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b.

Today at about 4:30 am I saw the conjunction of Venus and Jupiter, where they were about the width of the full moon, or one half degree apart. Did anyone else see it? Edit: The moon is 2,200 miles in diameter and at a distance of 240,000 miles. Thereby it subtends an angle in radians of 2,200/240,000=.01 (approximately). With pi radians being 180 degrees, one radian is 57.3 degrees, so that .01 radians is about .50 degrees (angle subtended by the moon). (.57 to be more exact, but with...
