One noticeable effect from an accelerating, expanding universe is what's called a redshift in the electromagnetic spectra of distant objects. Analogous to the Doppler effect observed in sound waves, a redshifted electromagnetic spectrum (REMS) is what we call an EM spectrum that was expected to be seen at one specific position within the total EM spectrum (TEMS), but instead was seen at a position proportionally shifted in the red direction of the TEMS relative to the center of the visible light spectrum. A shift towards the red (on the real number line, a shift in the red direction would be analogous to a shift in the negative direction, whereas a blueshift would be a shift in the positive direction) means that the observed EM waves have a proportionally longer wavelength than what was expected, which implies that the object being measured is accelerating away from the observer.

Why is the universe cooler?
It is because the Universe is expanding.
When was ...And the Ever Expanding Universe created?
...And the Ever Expanding Universe was created on 2009-07-14.
Is expanding universe accurate?
All the available evidence strongly indicates that the Universe is, indeed, expanding.
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.
Do volume in the universe change?
Yes. The Universe is expanding.
What does the redshift tell us about the universe?
that 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.
Who showed that other galaxies exsisted and obsereved that the universe is expanding?
Edwin Hubble was responsible for the concept of the universe expanding.
Why galaxies are going far away and the universe seems to expanding?
That's because the Universe really is expanding. It started as a "big bang", where all the matter and energy in the Universe was concentrated in a tiny space, smaller than an atom - at a tremendous temperature and pressure. From there it started expanding, and continues expanding to this day.That's because the Universe really is expanding.
