Hey,
After watching a show on TV about expanding universe and dark matter&energy, I wondered the following.
In the program, it was mentioned that the universe is expanding at an accelerated rate. This was measured using spectroscopy, comparing Type 1A supernovaes at different distances. It was discovered that Type 1A supernovas at a greater distance were moving away from us at a greater speed then the supernova's closer to us. So it was concluded that the universe is expanding at an accelerated rate.
That got me wondering... Because it takes millions of years for that light to reach us, doesn't that mean that: The supernova that is farther away is what is actually was going on for instance 100 million years ago and a supernova closer to us for instance 30 million years ago, which automatically means that of-course it seems that the supernova farther away is moving faster because what we are seeing is closer to when the big bang happened then the supernova closer to us.
Am I missing something here, or is my data just wrong?
