The main evidence is the redshift of distant galaxies; the only sensible explanation is a cosmological redshift, related to an expanding Universe. Other pieces of evidence are the microwave background radiation, which agrees very well with the predictions made by the Big Bang theory, and Olber's paradox - among others.
We know the universe is expanding because we can measure the redshift of distant galaxies. This redshift indicates that galaxies are moving away from us, and the further away a galaxy is, the faster it is moving away. This observation supports the idea of an expanding universe.

What is happening to the universe since it was formed?
The universe is expanding.
The discovery of a red shift in the spectra of galaxies provided evidence that the universe is?
expanding.
How did the space start?
The universe began with the Big Bang about 13.8 billion years ago. During this event, all matter and energy were concentrated into a single point before rapidly expanding, creating space and time as we know them. Since then, the universe has been continuously expanding and evolving.
What did Edwin Hubble discover in 1927?
universe is expanding
Why does the red shift of galaxies provide evidence that the universe is expanding?
It means that the light from galaxies is losing energy. The only reasonable explanation for this is the cosmoligical redshift - that is, that the Universe is expanding.
What is the universe expanding in to?
It is not exactly expanding into anything. We don't really know.
How do we know the universe is expanding?
well we don't
Why is the universe cooler?
It is because the Universe is expanding.
Is expanding universe accurate?
All the available evidence strongly indicates that the Universe is, indeed, expanding.
When was ...And the Ever Expanding Universe created?
...And the Ever Expanding Universe was created on 2009-07-14.
What are 3 possible outcomes of the universe?
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)
If scientists say the universe is everything and the universe is always expanding then what is the universe expanding into?
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.
When the universe is expanding?
the universe is expanding continuously even right now as you read this little sentence I wrote.
Fifty brightest stars in the universe?
That question cannot be answered. We would have to know the magnitude of every star in the universe. The universe is infinite (and expanding). It's impossible to answer your question.
Do volume in the universe change?
Yes. The Universe is expanding.
What is happening to the universe since it was formed?
The universe is expanding.
Is your universe contracting?
No, it is expanding.No, it is expanding.No, it is expanding.No, it is expanding.
