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?
1. The current (critical) density of our universe is pe = 10-26kg/m³. Assume the universe is
filled with cubes with equal size that each contain one person of m = 100kg. What would
the length of the side of such a cube have to be in order to give the correct critical density?
How many hydrogen atoms would you need in a box of 1 m³ to reach the critical density?
The matter we know, which consists mostly of hydrogen, constitutes only 4.8% of the current
critical energy density of our universe. So how many hydrogen atoms are actually in a box
of 1 m3 in our universe? Deep space is very empty and a much better vacuum than we can
obtain on earth in a laboratory.
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.

- Consider 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. O 1 million years, 9 billion years, today.arrow_forwardExplain the Higher-Order Systems?arrow_forwardI attempted to answer this question and I'm not sure what I am doing wrong. My formula says A.S. = 206265 (separation/distance from observer) I know to convert to the same units, so I ended up with 80 Million Km being 8 x 10 ^ -6 LY Could you please explain each step especially for the part that I got wrong for both A and B?arrow_forward
- mathematician Archimedes, responding to a claim that the number of grains of sand was infinite, calculated that the number of grains of sand needed to fill the universe was on the order of 1063. Our understanding of the size of the universe has changed since then, and we now know that the observable universe alone is a sphere with a radius of 1026 m. Estimating the size of a grain of sand, A) Approximately how many grains of sand would fill the observable universe? B) How many times larger or smaller is this number than Archimedes' result?arrow_forwardPerhaps the most fundamental problem in all of astronomy is the determination of distance to the various objects in the cosmos. Which of the following seems least reasonable regarding the various measurement techniques: Group of answer choices The Hubble Law relates the recessional speed of distant objects (measured with the Doppler Effect) to distance. Hubble law is most useful for determining the distance to nearby objects, while parallax is most useful for the more distant objects. We can determine the position of a star on the H-R diagram through spectral analysis and then figure out the distance by comparing absolute luminosity (from H-R diagram) to apparent brightness. The distance to nearby stars can be determined by measuring parallax. The distance to the planets in our solar can be determined by measuring the time for a radar signal to reach a planet, bounce off, and return.arrow_forwardThere are 3 parts to this question and I need three different answers!

- I'm having trouble understanding this. Suppose we have a spaceship about the size of a typical ocean cruise ship today, which means it has a mass of about 130 million kilograms, and we want to accelerate the ship to a speed of 12 % of the speed of light. Suppose you want to generate the energy to get it to cruising speed using matter-antimatter annihilation. How much antimatter would you need to produce and take on the ship? Express your answer using two significant figures.arrow_forwardStuck on homework, especially the significant part. If the value of the Hubble constant is 70 kilometers per second per Mpc, then what is the Hubble time – that is, the amount of time the universe has been expanding since the Big Bang? Give your answer first in units of seconds, and then in units of billions of years. Your answer is significant to two digits.arrow_forwardScientific models are often built in stages or layers, starting with a single idea.
