'Expanding universe' presentation slideshows

ASTR 2320 General Astronomy II. Professor Mike Brotherton Chapter 19 – Cosmology We shall not cease from exploration, and the end of all our exploring will be to arrive where we started and know the place for the first time. -- T. S. Eliot. Cosmology.

Assigning a distance by redshift. The Hubble law lets us use a simple spectrum of a galaxy to figure out. where it is along the line-of-sight. Higher redshifts indeed go with smaller and fainter looking galaxies. Redshift takes us from 2-D to 3-D.

Cosmology – The Origin and Evolution of the Universe. Expanding Universe – consistent w/ a Big Bang? Olber’s Paradox Large Scale Structure and relation to Dark Matter Evidence for the Big Bang The Cosmic Microwave Background The abundances of the elements

The Expanding Universe. Tuesday, January 15. Thomas Digges (16 th century) proposed an infinite universe. Infinite universe: hard to reconcile with appearance of the night sky. Night sky is dark , with stars (small in angular size) scattered across it.

Earth Science 25.3 The Universe. 25.3 Part B The E xpanding Universe. Earth Science 25.3 The Universe. The Expanding Universe: Recall the Doppler Effect from our previous chapter.

Assigning a distance by redshift. The Hubble law lets us use a simple spectrum of a galaxy to figure out. where it is along the line-of-sight. Higher redshifts indeed go with smaller and fainter looking galaxies. Redshift takes us from 2-D to 3-D.

Distances to Astronomical Objects. Recap. Canvas homework due Wednesday Lab this week: Parallax Overview of the Universe Solar System, Galaxy, Universe Largest scales Expanding Universe Evidence for a Big Bang Evidence for an accelerating Universe  dark energy Recurring themes

Universal Perspectives. Developed by Joe Naumann UMSL. The Historical Perspective. Compressing the geologic history of the Earth into one calendar year. Another way of looking at our place in the grand scheme of things. The Beginnings. Jan 1, 12:00:00 AM The planet takes shape

Our Expanding Universe. What is a Theory?. Not a fact A hypothesis that has lots of support Accepted hypothesis. Big Bang Theory. Most popular theory Says that at first matter was in one small area, and than it got so hot it exploded

Cosmology and Clusters of Galaxies. Patrick Koch. Cosmology: - what is cosmology? - principles - Big Bang: theory and tests - structure in the Universe Clusters: - largest bound objects - X-ray observation - a many-purpose tool

A Quick Review of Cosmology: The Geometry of Space, Dark Matter, and the Formation of Structure. Goals D escribe the structure, mass-energy content and the evolution of the universe as a whole. .... a nd how we know this. I nterpret observations of objects „at cosmological distances“.

ORIGIN OF THE UNIVERSE. Astronomers today believe the universe exploded (expanded) outward from a single point. This idea is known as the. Big Bang Theory. What evidence supports the Big Bang Theory?. the red shift in the spectral lines of distant galaxies.
