By using some method other than the Doppler effect to calculate the distance of a distant galaxy, and using the Doppler effect to see how fast it moves away from us. A galaxy's distance and how fast it moves away from us are roughly proportional.
The universe is expanding.
Galaxies in the expanding universe are moving away from each other at speeds proportional to their distance, with more distant galaxies moving faster. This phenomenon is known as the expansion of the universe.
It is because the Universe is expanding.
All the available evidence strongly indicates that the Universe is, indeed, expanding.
...And the Ever Expanding Universe was created on 2009-07-14.
1. the universe continues to keep expanding 2. the universe slowly stops expanding 3. big crunch (basically the universe will stop expanding and fall back into itself)
It is not exactly expanding into anything. The galaxies are moving apart from each other, from which we can infer that the universe is expanding. Theoretically, this is a result of the Big Bang, in which the universe began when all matter was compacted into a very tiny sum, and then exploded apart in a very big bang, and as a result is still expanding today.
the universe is expanding continuously even right now as you read this little sentence I wrote.
