What is the estimated age of the Universe (in years) if the Hubble constant is 70 km/s/Mpc?
Assume the observable Universe is charge neutral, and that it contains n nuclei (hydrogen plus helium nuclei, ignoring other elements). Take the helium mass fraction as 1/4. How many electrons are there in the observable Universe? Enter your answer in scientific notation with one decimal place.
Value: n = 4*1080

- What evidence shows that the Universe is expanding? What evidence shows that the Universe began with a Big Bang?arrow_forwardThe figure below is based on an assumed Hubble constant of 70 km/s/Mpc. How would you change the diagram to fit a Hubble constant of 50 km/s/Mpc? If the evolution of the universe were determined only by gravity, then its fate would be linked to its geometry. Open Negligible normal matter Flat Closed 14 9.5 Past Future Time Billion years ago Now The slope of the "negligible normal matter" line would be ---Select--- C and cross the time axis ---Select--- O than 14 billion years ago. The curved line separating the open and closed universe regions would cross the time axis O than 9.5 billion years ago. ---Select--- Scale of the universe, R © Cengage Learning 2013arrow_forwardIf a galaxy is 9.0 Mpc away from Earth and recedes at 488 km/s, what is H0 (in km/s/Mpc)? km/s/Mpc What is the Hubble time (in yr)? years How old (in yr) would the universe be, assuming space-time is flat and the expansion of the universe has not been accelerating? How would acceleration change your answer? A.If the expansion of the Universe has been accelerating, the Universe could be substantially younger than the value entered above. BIf the expansion of the Universe has been accelerating, the Universe could be substantially older than the value entered above.arrow_forward
- With the aid of one or more diagram, explain how observations of the CMB can be used to determine whether or not space is flat, positively curved or negatively curved. Describe two pieces of evidence that have led to the suggestion that the Universe contains Dark Energy.arrow_forwardIf we assume that the universe has been expanding at its current rate for its entire history, how old is the universe?arrow_forwardConsider three periods in the history of the Universe: one million years after the Big Bang (age = 1 million years), about five billion years ago (age = 9 billion years), and today. What is the ranking in the expansion rate of the Universe in these three period, from fastest to slowest expansion: O 1 million years, today, 9 billion years. today, 1 million years, 9 billion years. today, 9 billion years, 1 million years.

- How old is the wild the universe be, assuming space-time IS FLAT and the expansion of the universe has NOT been accelerating?arrow_forwardWhat would be your estimate for the age of the universe if you measured Hubbleʹs constant to be 33 km/s/Mly? You can assume that the expansion rate has remained unchanged during the history of the universe.arrow_forwardWhat was the lowest temperature for photons to be able to produce 0 particles in the early universe? Approximately what time was this? Let kT = mc2 and use Figure. Use the mean value of the distributionarrow_forward
- What is the evidence that the universe was very uniform during its first 400,000 years?arrow_forwardIf a galaxy is 8.9 Mpc away from Earth and recedes at 497 km/s, what is H. (in km/s/Mpc)? km/s/Mрс What is the Hubble time (in yr)? years How old (in yr) would the universe be, assuming space-time is flat and the expansion of the universe has not been accelerating? years How would acceleration change your answer? If the expansion of the Universe has been accelerating, the Universe could be substantially younger than the value entered above. If the expansion of the Universe has been accelerating, the Universe could be substantially older than the value entered above.arrow_forwardYour friends are talking about Olber's Paradox: Friend 1: When the universe was quite young, it was also quite small, and therefore light was trapped inside the universe. This is why we don't see light from the edge of the universe in every direction. Friend 2: No, Olber's Paradox describes only light from stars, not from galaxies, and why you can't use light from distant stars to see at night. Friend 3: You're both right and you're both wrong. The paradox concerns itself with the expansion of the universe, and explains why light from the early universe was able to be released. Are any of them right, in part or in whole?arrow_forward
