- How many times longer than the length of recorded history is the age of the universe? I was also given that the length of recorded history is 10E11 s, and that the age of the universe is 10E18 s. But, when putting 10E18/10E11 = 10E7, I get the wrong answer.Calculate the age of the universe for the following Hubble's constant, (a) 30 km/s/MpcSuppose a hypothetical universe is expanding (at some moment in time) at a rate of H. What would the density of this universe need to be (at this same moment in time) in order for it to be spatially flat? Value: H = 80 km s-1 Mpc-1 Give your answer in units of (kg m-3), in scientific notation with one decimal place (two sig figs). Please show work because I have trouble following along
- Your 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?Another explanation for the Universe is the Steady State Hypothesis. The Steady State Hypothesis says that the Universe has always existed and is infinite in extent. Which of the following supports the Big Bang Theory and which supports the Steady State Model. (Select B-Big Bang Theory, S-Steady State Model, If the first is B and the rest S, enter BSSSSS). A) An observation that some globular clusters show M-type stars that have evolved off the main sequence. B) The measurement of redshifts that show galaxies appear to be moving away from each other and the Universe is expanding. C) A measurement that shows the density of the Universe is close to the critical density. D) The measurement of the microwave background radiation. E) Observing that galaxies at very large distances look identical to those in the nearby universe.Hubble's First Attempt. Edwin Hubble's first attempt to measure the universe's expansion rate was flawed because the standard candles he was using were not properly calibrated. Look at (Figure 1) a.Estimate the value of Ho corresponding to the solid line in the figure. Express your answer kilometers per second per million light-years to two significant figures. b.What is the approximate age of the universe indicated by that erroneous value of Ho? Express your answer in years to one significant figure.
- If the speed of light is given as 299,792,458 meters per second and the wavelength is 560 nm. what is the frequency of this light? Give your answer in THz!T/ F The distance unit best for interstellar distances is the light-year. ___ The distance unit best for intergalactic distances is the mega-parsec. ___Calculate the number of miles in a light year using (see picture for the equation) mi/s as the speed. Hint: The number of seconds in a year,365days,will be useful.
- If Jim could drive a Jetson's flying car at a constant speed of 330 km/hr across oceans and space, approximately how long (in millions of years, in 106 years) would he take to drive to a nearby star that is 8.7 light-years away? Use 9.461 × 1012 km/light-year and 8766 hours per year (365.25 days).Figure 2 shows the "rotation curve" of NGC 2742. It plots the “radial velocity (V)" (how fast material is moving either toward or away from us) that is measured for objects at different distances (R = radius") from the center of the galaxy. The center of the galaxy is at 0 kpc (kiloparsecs) with a speed of 9 km/sec away from us. (These velocities have been corrected for the observed tilt of the galaxy and represent true orbital velocities of the stars and gas.) 200 100 U4779 -100 As you can see, one side of the galaxy is moving with a negative velocity (spinning toward us), while the other side has a positive velocity (spinning away from us). Using Newton's gravity equation, we will be able to determine the gravitational mass of the entire galaxy and how the mass varies versus distance from the galaxy's center. -200 -8 8 -4 Radius (kpc) Read the following text carefully and follow the instructions: Select five radii spaced evenly from 0-10 kpc across the galaxy.
