How Did the Universe Begin and How Does the Big Bang Theory Explain How the Universe Was Created?
The most popular theory about the universe’s creation is called the big bang theory.
It is based on the ideas of many scientists, especially Edwin Hubble, a famous twentieth-century astronomer.
The big bang theory claims that the universe was created by a massive surge of energy and matter 10 to 20 billion years ago.
The big bang formed celestial gases and particles, and everything that exists.
The theory also states that the universe continues to expand, that all the celestial bodies, galaxies, stars, and planets, to name a few, are constantly moving away from each other.

Is There a Highest Temperature That Can Be Achieved?
Although there is an absolute zero temperature, there is no highest temperature.
The highest temperatures achieved to date have been from nuclear explosions, where the temperature can reach as high as one hundred million kelvins.

How Can You Pass 24 Hours In Less Than 60 Minutes?
The lines that divide the world’s time zones meet at the North and South Poles, so the zones get narrower as they near’ the poles.
An Alaskan airline offers a flight over the Arctic regions that includes a circular flight around the North Pole. If you were to circle the North Pole, you’d pass through all the world’s times zones in less than an hour!
If it were noon when you started to circle the pole, you’d soon pass the line marking the beginning of the next time zone, and it would become one o’clock. A few minutes later, you’d have to move your watch ahead another hour.
As the flight continued, you’d keep moving your watch ahead, past midnight, through the morning, until you returned to your starting point, before clocks there had reached one o’clock.

How Were the Hawaiian Islands Formed From Volcanoes?
The Hawaiian volcanoes could be said to be more creative than destructive.
Volcanic activity built this chain of islands, and the only known deadly eruptions killed a division of the Hawaiian army—in 1790—and one other person—in 1924. The 1969 eruption took no lives.
Four shield volcanoes make up the island of Hawaii. Mauna Kea first grew to 13,825 feet (4,200 meters) above water. The smaller volcanoes, Kilauea and Haulalai, then sprouted from its sides.
Further internal volcanic activity then created Mauna Loa, 13,678 feet (4,169 meters) in the air. The mild nature of these volcanoes allowed the United States to open them, and Haleakala on nearby Maui, as the Hawaii Volcanoes National Park.
Since 1911, the Hawaiian Volcano Observatory on Hawaii has gathered an immense amount of data and information on volcanology, the study of volcanoes.

Where Are Volcanoes Located On Earth and Which Areas Do Not Have Volcanoes?
Some places on Earth are especially likely to have volcanic activity. Most of these sites mirror where Earth’s tectonic plates come together and move apart.
The Pacific region hosts the largest concentration of volcanoes, called the “ring of fire.†There are also volcanoes in the Mediterranean Sea, Africa, and the Atlantic Ocean.
Throughout the world there are places called hotspots. Scientists have determined that these areas, while not necessarily residing over the edges of tectonic plates, show accelerated magma movement and heat.
They are also likely places for volcanoes to erupt.
