Red shift and parallax.
All elements have characteristic frequencies of light which they absorb. Elements in the outer regions of a star thus create clear black lines in the star's spectrum. The light from a star which is moving away from us is red-shifted. This means that the frequencies are moved towards the red end of the spectrum. According to Hubble's findings, the further a star is, the faster it is moving away from us. And the faster it is moving, the greater the red shift. So, by measuring how far some of the absorption lines have been red-shifted provides a measure of its distance.
The apparent position of a relatively nearby object, with reference to a static background will change as the position of the viewer changes. Using the change in the apparent direction to an object in the universe form two diametrically opposite positions in the earth orbit, combined with some pretty basic trigonometry allows the distance to the object to be calculated.

How do scientists explain the origin of the universe?
By thinking of how to do it and showing evidence. muhaaa!
What are some things that scientists could not explain now?
Quantum mechanics - why matter behaves as it does on the quantum level. What exactly happened at the very beginning of the universe. Where dark matter comes from.
What does the nebular hypothises explain?
the formation of the universe

What was the first event in the universe?
Scientists believe the "first event" in the Universe was the Big Bang. The Big Bang Theory attempts to explain how the universe was originally created.
What is something that scientists use to explain something that is very small or very large?
Exponents is something scientists use to explain something that is very small or very large. Scientific notation is another useful tool.
Can you believe in the bigbang theory?
Atleast 80% because bigbang is the is the only theory yet which has helped the scientists to understand and explain all the other systems of the universe.
Explain how genetic engineering produces tomatoes that are ripe when they reach consumers?
Scientists have introduced a gene into the tomatoes that allow then to be picked green and transported great distances before they ripen completely.
Why do people feel the need to explain the beginning of the universe?
People feel the need to explain the beginning of the universe because understanding our origins can provide a sense of purpose, meaning, and direction in our lives. Additionally, it helps us make sense of our existence and the world around us.

What is accelerating universe?
An accelerating universe is a theory which describes and seeks to explain the increasing rate of the expansion of the universe.
