Is the Universe older than we think? - Physics Forums
WEBNov 25, 2023 · The James Webb Space Telescope, JWST, has revolutionised our views of galaxy formation in the early universe, suggesting that galaxies showing structure may have been formed at much earlier times than our best models of galaxy evolution predict. This has even led to suggestions that The Universe...
Why does Webb orbit L2, is it because of the Moon? - Physics …
WEBDec 24, 2021 · Of the Lagrange points L1, L2, and L3 are unstable and L4 and L5 are stable. Seen from the rotating frame of reference, where the Lagrange point under consideration is fixed you have of course an interplay of the gravitational force and the inertial forces (i.e., both the Coriolis and centrifugal forces).
How did Earth get so far away from other galaxies? - Physics Forums
WEBDec 10, 2022 · The light that the James Webb telescope is seeing that came from those galaxies had to travel 13.3 billion light years to get here. That means the mater that became earth, if it was at the opposite edge of the universe from the light emitting galaxies, had to travel at least 12.7 billion light years (13.3-0.6) in 13.3 billion years in order to ...

Is there a specific unit used to measure redshift? - Physics Forums
WEBMar 30, 2018 · While the idea of a unit for redshift may seem useful, it is not necessary for the study of distant galaxies and the upcoming launch of the James Webb Telescope and E-ELT project. The distance in an expanding universe is calculated based on a model of the universe's expansion over time, making it a complicated measurement.
It's still not clear to me what's the limit of light propagation
WEBMay 7, 2024 · The James Webb Space Telescope manages to detect very distant stars an galaxies because it's placed a million miles away from the (warm) Earth and has a very effective sun shade and a cryocooler so the temperature of its sensing equipment is kept at just 7K !!! That means the limit that you have asked about corresponds to the most …
