What is the conclusion in expanding of the universe?

In conclusion, in an expanding universe everything expands (or contracts) but at different rates, according to the interactions that hold the different bodies together. In general the expansion (contraction) rates are quite small and can be neglected for all practical purposes.

What does blowing the balloon represent what conclusion can be drawn about the universe?

When the balloon is inflated, its surface area increases and so the dots on the surface (representing galaxies) move further apart. This observation supports the big bang theory that the universe is expanding and the galaxies are therefore moving further apart.

How is the universe like an expanding balloon?

The balloon is the universe, and as more air is blown into it, you would see the space or surface area of the universe expanding and every point on its surface getting further and further away from one other. It’s been suggested that this idea ties into the likely existence of multiverses, or multiple universes.

What is the evidence of expanding universe?

In his short paper, Hubble presented the observational evidence for one of science’s greatest discoveries—the expanding universe. Hubble showed that galaxies are receding away from us with a velocity that is proportional to their distance from us: more distant galaxies recede faster than nearby galaxies.

How old is the universe conclusion?

Universe is 13.8 billion years old, scientists confirm.

How was the universe formed step by step?

Our universe began with an explosion of space itself – the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.

What is the relationship between the expansion of the universe and the distance between galaxies?

As the universe expands, the galaxies get farther from each other, and the apparent velocity will appear to be larger for the more distant galaxies. The Earth and the Milky Way are not special in seeing that all galaxies appear to be moving away from us.

How does the expanding universe affects the position of the celestial bodies?

The expansion of the universe does not affect the relative position of astronomical bodies within galaxies. It is true that the universe is expanding, but this does not alter the distance between the earth and the sun. Because the expansion is space itself, there is no center.

What can you conclude about the expansion of the universe based on the activity?

Answer. When scientists talk about the expanding universe, they mean that it has been growing ever since its beginning with the Big Bang. The galaxies outside of our own are moving away from us, and the ones that are farthest away are moving the fastest.

What did Galileo’s telescope reveal?

With this telescope, he was able to look at the moon, discover the four satellites of Jupiter, observe a supernova, verify the phases of Venus, and discover sunspots. His discoveries proved the Copernican system which states that the earth and other planets revolve around the sun.

Is the universe expanding like a balloon?

I’ve heard that the universe is expanding similar to a balloon being blown up with all reference points growing further apart. If this is true, then all movement is perpendicular to the point of origin (the “center of the balloon”). An observer on the balloon (Earth) would see lateral movement of all stars in all directions except ahead and behind.

How do you demonstrate the expansion of the universe?

This is a very simple experiment to demonstrate the Universe expansion theory. Blow up the balloon so its about the size of an orange. Clip it with a balloon clip. Draw dots on the balloon with a black marker, these represent the the milky way galaxy. Remove the clip and keep blowing up the balloon.

What is the size of the universe in the balloon analogy?

SECOND: SIZE/SHAPE The analogy should ONLY consider a portion of the balloon’s surface — it does not make any statements about the size or shape of the universe (other than it is getting bigger). Forget that the surface of the balloon is curved. That’s NOT intended to be representative of the actual universe.

Why is the circumference of the balloon important to this experiment?

Yes, the circumference of the balloon is important to this experiment because it gave the demonstration that as the balloon inflates, the dots move further apart from each other. The circumference of the balloon shows that the larger the circumference, the larger the distance between the dots.
