Web8. júl 2024 · Astronomers measure distances in the universe by using the Doppler effect. The Doppler effect is the change in wavelength of a wave as it moves away from or towards the observer. By measuring the Doppler shift of light from distant objects, astronomers can determine the object’s motion and, from that, its distance. Web25. apr 2012 · In this paper, we examine the origin of redshift in the Friedmann–Robertson–Walker (FRW) metrics with constant space–time curvature, and show that – at least for the static space–times – the interpretation of z as due to the ‘stretching’ of space is coordinate dependent.
Web30. mar 2024 · The newly detected star is so far away that its light has taken 12.9 billion years to reach Earth, appearing to us as it did when the universe was only 7 percent of its current age, at redshift 6.2. The smallest objects previously seen at such a great distance are clusters of stars, embedded inside early galaxies. WebCredit: NASA/JPL-Caltech//R.
