The correct option is :
The universe became transparent to photons of radiation
In the present theory of the Big Bang, what significant event occurred at about 400,000 years...
The "classic" Big Bang theory explains that the Universe was originally very hot and very dense and that this leads to some clear predictions that have been experimentally verified.However, there were some observed properties of the Universe that the classic Big Bang theory couldn't explain. Explaining these additional properties of the Universe required the development of the model of cosmic inflation in the 1980s, which has some additional predictions we are attempting to verify with experiments today. What properties of...
The Big Bang theory predicted * Choose one or more: A. the cosmological principle. B. the cosmic microwave background radiation. C. the abundance of helium. D. that the sky should be dark at night. E. Hubble's law. F. the period-luminosity relation of Cepheid variables.
How and why does the CMBR, redshifts of distant galaxies, and relative abundances of the elements support a beginning to our universe? About 380,000 years after the big bang, the universe became transparent to light. What had to occur for this to happen and what remnant is left behind that we can see today? Go to Planck and The Cosmic Microwave Background and answer the following: How accurate is the the Planck data? What do the different colors help us...
Weeks 5, 6: How is Olber's paradox solved? Does the Universe have a center or an edge? What is the cosmological principle? The Universe expands: why, how, and how do we know? What is cosmological redshift? What is the Big Bang? How old/big/fast is the Universe? How do Hubble's constant, the critical density of the flat universe, and the density parameter help us understand those properties of the Universe? What is the cosmic light horizon and why is it the...
What types of organizational culture apply to J.C. Penney before and during this change in leadership? CASE DESCRIPTION Leadership is the primary subject matter of the case. Secondary issues that may also be examined are corporate culture and the marketing mix of product, price, place and promotion. The difficulty level of this case is a three. It would be appropriate for junior, senior and graduate students. The case may be taught in as little as one hour or could easily...
