Assume the universe today is flat with both matter and a cosmological constant but no radiation.

a) Compute the horizon of the Universe as a function of Ohm_M and sketch it. (You will need a computer or calculator to do this.)
b) What is the current horizon size for a universe with Ohm_M = 1/3 and h =1/sqrt(2)?
c) What is the mass contained within the current horizon in solar masses? If all objects were 10^13 h^-1 M in mass, how many are in the observable universe.

  • How Large is the Universe now - Red Shift

    A simple formula to calculate the degree of expansion of the universe is Size (Now) = Size (Then) * (1 + z) For z = 1, Size (Now) = Size (Then) * (1 + 1) = 2 * Size (Then) This means, we see a galaxy with z = 1 at a time when distances between

  • Fate of the Universe

    In the question above, would the universe have a finite size or would it be indefinitely large? The solution file is attached. Fate of the universe is discussed.

  • Big Bang Theory & Relevant Creation Philosophies

    Space travel, but robotic, computer, or humans will further our knowledge, but we cannot yet "map" the size of the universe, let alone decide what that moment was or why it occurred. I don't know that we want to know and care.

  • Big Bang Theory; Observational Evidence

    In conclusion, no body now thinks that the universe was static in size. We learned that the universe is expanding in volume, and tracing the expanding universe backward in time to a hot, dense beginning is a finite past.

  • Cosmic Inflation and the Horizontal and Flatness Problems

    We measure distance on the Universal scale in terms of how fast light travels due to the vast size of the Universe so these distances would be light years.

  • Are the stars uniformly distributed in space

    This suggests that one of the main postulates of cosmology - that the universe looks exactly the same from any point in the universe is probably true, and that the distribution of mass on the scale of the universe is pretty much uniform.

  • Evidence Supporting the Big Bang Theory

    The Big Bang theory explains that when these dense singularity becomes inflated or expanded and cooled, it went from the very, very small and very hot to the size and temperature of our current universe today.

  • Paley's Teleological argument for the Existence of God

    d) Size of a product does not imply the size of a designer (rocket ships or space stations and their engineers, anyone?). Lots to consider as far as issues with the argument itself; I'm sure you'll agree.

  • The Big Bang Theory of Cosmic Origins

    Cosmic matter becomes denser and hotter, until the universe is only a fraction (one hundred millionth) of its current size and the temperature of its background radiation is 273 million degrees above absolute zero.
