The metric describing the miverse as whole is usually written as ds2dt where a(t) 0 characterizes the change to the size of the niverse from expansion in time (i) show that we can write this as where a(r) at() derive an integral expression for r in terms of t. (ii) what is τ in terms of t when a("'? if t € 0.oc), what is the range of r? (ii) in terms of r and ž, what are the trajectories that light follows?

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!
