Im very new to astronomy and astrophysics, so this may be a very simple question. I read somewhere that astronomers observed that galaxies further away were moving away at a faster speed than galaxies closer to us. Hence, the universe is expanding at an accelerated rate. However, when we observe the galaxies that are further away, we are actually observing those galaxies as they were millions of years ago. Doesn't that mean that the speeds we observed were the speeds millions of years ago and not today? Could it be that those same galaxies are moving slower today?
