What else can I help you with?
How do you know what to believe about space when most of your observations are made from earth?
We rely on a combination of observations made from Earth and in space to build our understanding of the universe. Observations from telescopes, spacecraft, and other instruments in space provide us with valuable data that complements Earth-based observations. By combining these different sources of data, we can develop a more comprehensive picture of space.
How do emission and absorption spectrums tell us about the composition of objects in our universe?
Each chemical element has a specific emission or absorption spectrum.
When was The Universe Around Us created?
The Universe Around Us was created in 1929.
What time is it at greenwich at longitude 74 degree west?
If you tell us the time at either Greenwich or at 74° west, then we can tell you the time at the other point. They do track together, but both of them keep changing.
Is the center of the universe very close to us?
The concept of a center of the universe is not well-defined in modern cosmology. The universe is expanding uniformly in all directions, which means there is no specific central point. Each observer perceives themselves to be at the center due to the nature of the expansion.
How do astronomers find out about changes in galaxies over time?
Astronomers can watch galaxies that are far away. Since the light takes billions of years to reach us from the farthest known galaxies, they would be watching galaxies in the early Universe. It turns out, from such observations, that the Universe is changing.
What does the red shift tell us about the changing universe?
Mainly that the Universe is expanding. Analyzing far-away galaxies, it has recently become clear that the expansion is accelerating - the Universe is now expanding faster than a few billion years ago.
What does the Doppler Effect tell astronomers about the universe?
It tells us that the Universe is expanding.
What do observations of stellar explosions and nebulae tell us?
it is how the solar system started
What International Space Station tell us about the universe?
i donno
What does the Big Bang theory tell us about the universe?
The Big Bang Theory tells what happen at the begning of the universe. How the Earth comes into the universe
How does telescopes help tell us more about the universe?
It helps you learn more about the universe because you can see most of the things surround the earth.
How is the universe changing by red shift?
Redshift in the universe occurs as objects move away from one another, expanding the universe. This indicates that the universe is still expanding, consistent with the Big Bang theory. The rate of this expansion, known as the Hubble constant, provides insight into the age and future of the universe.

What does Albert Einstein discovery tell us about the solar system or universe?
it was really good and help for (not)
What do scientist tell us about the age of the universe and the age of the planet?
The universe is 13.7 billion years old & Earth is 4.5 billion years old.
What does the redshift tell us about the universe?
Redshift is a phenomenon where light from distant galaxies appears redder than expected due to the expansion of the universe. It tells us that the universe is expanding and provides evidence for the Big Bang theory. By studying the redshift of galaxies, scientists can understand the rate of expansion and the age of the universe.
