I confess that I find the fact that we can see across immense distances with a telescope as something that has not been fully analyzed in all its consequences — Hachem
Right now I am still wondering how distant stars can be reflected on our retina and how the moon can be reflected on a lake.
I am completely unsatisfied with the theory of the duality of light and will continue my reflexions and modest experiments with photographic gear (professional lab gear to study light is simply out of my reach), and see where that gets me. — Hachem
No one can "see" the universe in its entirety -- we are part of it, of course, or at least I hope we are -- and it exceeds our farthest reach of vision. Perhaps (or probably) some galaxies are already invisible to us, and will never be visible in the future. — Bitter Crank
I am suspicious of theories rejected by the consensus of the scientific community. If you look, there are lots of people that say relativity and quantum mechanics are hoaxes. At the same time, I am sympathetic to the frustration that comes from not understanding the chain of inference that scientists follow on complex issues. It would be helpful if we could get someone on the line who knows the science well. — T Clark
If this were so, the red shift would be greatest towards the mass that is pulling everything in since acceleration would be greatest there. Smaller red shift in the opposite, and blue shift in the other 4 directions as things parallel to us all get sucked closer to this mass. This tendency is called tidal force: expansion in 2 dimensions and contraction in the other 4, and is a signature of a strong gravitational field. — noAxioms
Rich, you're pretty up on your quantum mechanics and physics in general. Where is the flaw in the premise that the universe could be contracting, based on the red shift or anything else? — MikeL
This is what I am arguing. How does it look now? Again if there was shrinkage of space around the galaxies the blue shift could be compensated for. — MikeL
Could you provide me with the evidence for the expansion please. — MikeL
is the inference that we are at the centre of the universe, as everything is red-shifted away from us? — MikeL
The discovery is associated with Edward Hubble. It appears pretty solidly documented. — Wayfarer
Yes, under SR time and length are reciprocal. Contraction of length is ignored leading to all sorts of paradoxes. So many, that I simply game up on Relativity. It would be like spinning my wheels in Zeno's. None of it is real. — Rich
SR and GR are not different...
This seems to be very pseudo-scientific right here. SR is a special case of GR, which occurs mainly when we're dealing with flat, non-curved space. — Agustino
