Edwin Hubble
By Isamilla & Nelleke
The Hubble space telescope was named after Edwin Hubble.
He had three laws of motion.
He hypothosized that the nebulae were their own galaxies.
<span>He imagined the earth at the </span>
center of the universe with the sun, the moon, the stars and the planets orbiting it in perfect circles.
Newton put Kepler and Galileo's ideas together and discovered that the reason that things fall on the ground is the same reason that planets orbit around the sun.
He made a telescope that could magnify
up to 30 times.
<span>He discovered that Copernicus' theory </span>
was true. "We're not the center of the universe."
He found out that the planets orbit the
sun in ellipses (oval shapes).
He explained how the tides were made by the moon.
He figured out that the speed of the planets depend on the sun.

The factors which helped to spread summer vacations are: C. advertising, unions, and art.
<h3>What is an advertisement?</h3>
An advertisement can be defined as a group of consumer promotions programs which is designed and developed with the sole intention of making the various goods or services that are being offered by a business firm to become known, popular and familiar to all of its customers and potential customers.
This ultimately implies that, consumer promotions programs such as online websites and advertising, can help a business firm in the following positive ways:
- To generate store traffic.
- To enhance brand loyalty.
- To facilitate and influence the final decision to buy an item.
- To increase awareness and encourage the use of a service such as vacations
In this context, we can infer and logically deduce that the factors which helped to spread summer vacations include advertising, unions, and art.
