Suppose a galaxy is moving away from Earth at a speed of 0.78c. It emits radio waves of 0.680 m. What wavelength would we detect on Earth? with a wavelength
The red-shift of a galaxy observed by us corresponds to a speed of 50000 km/s. How far is the galaxy from us approximately? A. 700 Mpc B. 70 Mpc C. 7 Mpc D. 7 Gpc Is the answer A? Thank you!
Suppose an alien race on a distant planet tries to send a message to us, with a laser (light). However, we were unaware that there is a stellar-mass black hole almost directly between us and them. How would this complicate our attempts to locate their position in the Galaxy? O Gravitational lensing would make the signal appear to be coming from a different location O The information carried by the laser (light) would be altered O It would not matter The black hole absorbs all of the light
QUESTION 10 What curvature will the universe have if the matter and energy density of the universe is equal to the critical density? Open Closed Flat O None of the above QUESTION 11 Why can you not observe beyond the horizon distance? O Because of opaque gas O Because our telescopes are not powerful enough O Because light/information cannot travel faster than the speed of light O Because of the of black holes QUESTION 12 According to the Olber's Paradox, the night sky should be completely bright. However, when we observe at night, the sky is dark. Why does this happen? O Because the universe has a finite age O Because as the universe expands, objects at larger distances move faster, and the light from them shifts out of the visible part of the electromagnetic spectrum O Both a) and b) O Neither a) nor b)
What is the spatial radius of curvature for a hypothetical closed universe at a moment of time with given values below. Give the answer in units of Mpc, to the nearest integer (not in scientific notation - e.g., 1234). Values: H = 51 km s-1 Mpc-1 ρ = 2.9x10-26 kg m-3
What is redshift? I’ve heard redshift is kind of like how u measure objects in space but I’m still confused on the topic. Anyone understand? Pls help.
Briefly explain what is meant by “particle horizon” and “event horizon” in cosmology. Calculate the physical particle horizon, RH(t), at time t. Assume a flat FRW universe whichis dominated by a fluid that gives rise to scale factor evolution where n is a constant with 0 < n < 1, and a(t0) = a0.
