Introduction (5:03) 1. What is the name for all the electromagnetic waves that exist? Names of the electromagnetic waves that exist are Gamma Rays‚ X-Rays‚ Ultraviolet Waves‚ Visible Light‚ Microwaves‚ and Radio Waves. 2. What are electromagnetic waves produced from? What two things do they have? Electromagnetic waves are produced by the vibration of charged particles and have electrical and magnetic properties. 3. What is the name for the section of the electromagnetic spectrum that

galaxies‚ and the heavier elements were synthesized either within stars or during supernovae. The Big Bang theory offers a comprehensive explanation for a broad range of observed phenomena‚ including the abundance of light elements‚ the cosmic microwave background‚ large scale structure‚ and Hubble’s Law.[3] As the distance between galaxies increases today‚ in the past galaxies were closer together. The known laws of nature can be used to calculate the characteristics of the universe in detail back

The first piece of evidence that they had for the big bang was that they soon realize that the universe kept expanding. The second piece of evidence that they had about the big bang was The cosmic microwave background radiation. These two pieces of evidence support the big bang theory because they led to the conclusion that the big bang did occur. This big bang evidence helps us understand that the big bang made the universe expand every day. The most

Lesson 1 Key Question Answers 1. What does Hubble’s law predict about the speed of a galaxy far away from the Milky Way compared to one that is closer? Hubble’s law predicted that galaxies were moving away from earth at a rate proportional to their distance from us. The farther away from the Milky Way a galaxy is‚ the larger the redshift is. The farther away a galaxy is‚ the faster it is moving away. Conversely‚ blueshifted galaxies‚ such as Andromeda‚ are moving closer to the Milky Way.

What is the age an origin of our universe? The issue to be discussed in the following paper is the 3 theories of how the universe started‚ the Doppler Effect‚ the age of the universe‚ the origin of the universe‚ red shift/blue shift and dark matter/dark energy. The Doppler Effect is a change in frequency and wave length of a wave. It’s caused by the change in distance between the thing creating the wave and whatever it’s measuring‚ seeing and hearing the wave. The universe was created over 14

The Big Bang theory is today’s dominant scientific theory about the origin of the universe. It states that the universe was created from an infinitely hot and dense subatomic ball‚ which once exploded not only created energy and matter‚ but space and time itself. This is estimated to have happened around 14 billion years ago. 300‚000 years after the big bang took place the plasma of elementary particles had cooled to 3000K‚ during which atoms began to form as electrons came into orbit around protons

“Suppose you suddenly hear a loud bang… and ask me‚ ‘what made that bang?’ and I reply‚ ‘nothing‚ it just happened.’ You would not accept that.” (Strobel‚ The case for Faith‚ 76) Humans have‚ and always will‚ wonder about the beginning of time. Some creation theories are more widely spread and known than others. A common definition of a ‘theory’ is a proposed explanation whose status is still conjectural‚ in contrast to well-established propositions that are regarded as reporting matters of actual

Lacking adequate competition‚ the popular prototype has dominated the metaphysics front for the past two decades even though much of its complications have been left unresolved. With the advent progress in cosmic microwave background detection‚ these unsettled loopholes are begging for answers. A successful model that seeks to replace the Big Bang notion must be ready to explain the past‚ present and future states of the universe in an efficient and unified manner
