Big Bang Theory
When did the Big Bang Theory occur?
The Big Bang Theory occurred 13.8 billion years ago.
What is Scientific Notation?
Scientific Notation was developed in order to easily represent numbers that are either very large or very small.
When did the Solar System form ?
The solar system formed 4.6 billion years ago
When did Johannes Kepler theorized that planets orbit the Sun along elliptical paths, rather than circular paths?
Johannes Kepler theorized that planets orbits the sun along elliptical paths, rather than circular paths in 1609.
Which point in our solar system is always a focal point in every planets orbit?
Is it true that the universe is expanding and the galaxies are moving further away from each other?
It is true that the universe is expanding and the galaxies are moving further away from each other.
What is a base and what is a exponent?
A base is the number that will be increase by a power. A exponent is the power that will times the base.
Earth, Jupiter, Mars, Neptune, Saturn, Venus, Uranus, and Mercury.
What is the major axis?
The major axis is a line segment connecting the two vertices of the ellipse
During which month is Earth moving fastest around the Sun?
In January the earth is moving the fastest around the sun
What is the difference between dark matter and dark energy?
The difference between dark matter and dark energy is that dark matter doesn't give off light like a galaxy or absorb light like a black hole. Scientists know it exits because it has gravitational pull, just like normal matter. Dark energy is a mysterious pressure working in opposition to gravity, pushing matter apart.
How should Scientific Notation be written as?
Every number can be expressed in Scientific Notation. In our first example, 200,000,000,000 should be written as 2.0 x 1011. In theory, it can be written as 20 x 1010, but by convention the number is usually written as 2.0 x 1011 so that the lead number is less than 10, followed by as many decimal places as necessary.
What is a nuclear fusion ?
Nuclear fusion is when two light atoms combine to form a heavier atom , which releases a bunch of energy.. and that is how the sun was created.
What is the focus?
The sun is the focus
During which month is Earth moving slowest around the Sun?
The month that moves the slowest around the sun is July.
What did Hubble find out about the galaxies that are further away from Earth?
Hubble found out that the galaxies that are moving away from the Earth are red shifted
What does mean when there is a negative exponent?
When there is a negative exponent, the decimals point moves to the left.
The solar system formed by a collapse by a giant cloud of gas and dust, which is called nebula. The nebula was drawn together by gravity, which released gravitational potential energy.
What is the difference between Perihelion and Aphelion?
Perihelion is the point in the orbit of a planet, asteroid, comet which is closest to the sun. Aphelion is the point in the orbit of a planet, asteroid, comet which is furthest from the sun.
Order the planets from longest major axis to shortest major axis.
Neptune
Uranus
Saturn
Jupiter
Mars
Earth
Venus
Mercury
The big bang theory states that the universe expanded from a single point. However, planets, stars and galaxies did not exist in this point. How did these objects form according to the big bang theory?
After when the universe became less dense and cool, protons, neutrons, and electrons started to form. A few minutes later, Hydrogen was created and because of the nuclear fusion, it created helium. The clumps of matter that was held by gravity transformed into stars. Stars , billions of galaxies, and other structures formed the visible universe.
What is the standard notation of this scientific notation.. 5.72 x 10^9 ?
5,720,000,000
How is the universe attracted to each other?
All objects in the universe are attracted to each other due to gravity. Whichever object has more mass will have a stronger gravitational pull.
The shape of the planets that orbits around the sun is...?
The shape of the planets that orbits around the sun is an ellipse.
Which month during Earth's rotation would be considered the aphelion and which month during Earth's rotation would be considered the perihelion?
In January, the earth's rotation would be considered the aphelion. The month July would be considered the perihelion.
