WebAstronomer Edwin Hubble was already world famous for discovering that our galaxy is not the only one. His later observations in 1929 proved that all galaxies are moving away from us and moving faster the further away they are. Space itself is expanding. This proof was a shock to Einstein. WebHubble’s law ( v = H × d) allows us to calculate the distance to any galaxy. Here is how we use it in practice. We have measured Hubble’s constant to be 22 km/s per million light-years. This means that if a galaxy is 1 million light-years farther away, it … the overpowered protagonist ch 14WebBased on our current mathematical models, it appears our universe has an age, which is based on the start of the big bang. Our models cannot understand anything before the Big Bang. So we date it based on that. If new data leads to updated models that have a different age, we'll update it as needed - but based on the things we have observed. shurie graeve attorney
