The Hubble Tension is one of the most exciting mysteries in modern day science. Different methods give different results for the expansion of the Universe. So, how can we solve this and can James Webb help us with that? Or will it make things even worse? Finding out with Physics Nobel Prize laureate, Dr Adam Riess.

Would there be scientific merit in terms of parallax distance if we, say, launched two JWSTs in opposite directions towards outer the solar system? In 20 years you could image the same target from Pluto's orbit - on opposite sides of the solar system. That'd expand the angular resolution significantly. But would it be useful?

The true answer is no. All particles have atomic weight. It would be irrelevant as to where it is in space because it must maintain weight. Atoms are atoms and will not change weight. Telescopes are to see distance. Filters are to see what can not be seen. Particles and elements are defined. Mass and matter are measurable. Energy is not measurable. It is hypothesized. The speed of energy is hypothesized. What is absolute? Forward motion. Energy stores information. Consciousness deciphers energy and the information it stores. Life exists.

I’m a bit confused about the expansion of the universe. The farther away a galaxy is from earth the further back in time we are observing it. That means the expansion was faster in the far distant past than it was for a galaxy that is say half the distance and therefore is moving away at a much lower velocity. If we see a faster expansion in the far past and slower expansion in the near past does that indicate that the expansion is decelerating?

@rapragermusic 3 ай бұрын

Yes it would

@fto3367 3 ай бұрын

No. It's the opposite. The expansion of space is accelerating. The reason a distant galaxy "moves away" more quickly from us is because there is more expanding space in between. That would be the case even when the expansion of space is constant. The expansion didn't happen at the position and time of the distant ancient galaxy but homogeneously throughout the entire space on the light's journey.

The issue is likely to be an error in the assumptions made to complete the calculation of the Hubble/Universal Constant. Mostly likely that we assume gravitational redshift is negligible. The longer light travels the more time for the gravity of the universe to redshift the light and we do not have high certainty of where all the mass was in relation to the path of the photons we measure. Unaccounted for gravitational redshift could easily resolve the unresolvable issue of dark energy and inconsistent variable expansion rates.
