This equation is identical to the one which governs the behavior of a massive scalar field such as axion. Thus, the massive gravitons will be efficiently produced during inflation (cf. Ref. [ 41,42]). One may estimate the amount of the gravitational waves produced.

WebThe Hubble constant, H, has been measured by many experiments. One of the most recently published measurement by the ESA Planck Surveyor indicates, H ≈ 2.20 × 10 − 18 ± 2.50 × 10 − 20 ⏟ uncertainty s − 1. or equivalently in more common units (for the Hubble parameter), H ≈ 67.80 ± 0.77 km s Mpc. Share. WebThe radial velocity of a galaxy relative to us is proportional to the distance of the galaxy from us; thus the cosmic expansion can be represented by the “Hubble law”: v = H0d, where v is the radial velocity (ordinarily expressed as km/sec), d is the distance (as Mpc), and H0 is the Hubble constant (as km/sec/Mpc) at the present epoch. Web8 jun. 2024 · We have had the chance to live through a fascinating revolution in measuring the fundamental empirical cosmological Hubble law.

"Web5. Hubble's law states that v = H x. Age of the universe is calculated by T = x v = 1 H. but the velocity is not constant; it changes with distance, so I think that this equation cannot be applied because simply the velocity is NOT uniform. v should have been replaced with d x d t, so it gives this differential equation d x d t = H x.

Hubble kon in 1923 aantonen dat de waargenomen 'nevels' afzonderlijke sterrenstelsels waren, waarmee bewezen werd dat het heelal veel groter was dan aanvankelijk gedacht. Een van zijn belangrijkste ontdekkingen (1929) was dat er een verband bestond tussen de roodverschuiving van verre sterrenstelsels en hun afstand tot de aarde. Hierm…

WebThe Etherington reciprocity theorem, or distance duality relation (DDR), relates the mutual scaling of cosmic distances in any metric theory of gravity where photons are massless and propagate on null geodesics.
