s4w5 Expansions

Required

1

Math time! yes, this is for everyone! no, it shouldn't be too bad. your car is going 60 mph when you cross the state line, and the mile marker resets. you continue on at a constant velocity until you hit mile marker 120. How long have you been driving?

Required

1

If you are going a constant velocity, then the graph comparing how far you have gone and the time that has passed will be a straight line. What about that graph would show your speed?

Required

1

Which of the following charts show the above scenario

Required

1

Which of the following has a curve whose slope is decreasing as time increases?

Required

1

Which of the following is a curve whose slope is increasing as time increases?

1

watch the following video on the big bang. I want you take note of how many times the video mentions what we don't know, when something has multiple theories. Do you have any questions?

Required

1

A supernova 1a is not something they explain in detail here, but we did learn about it last session. Explain here, look it up if you need to.

Required

1

explain why a supernova 1a would have a consistent energy output, whereas a type 2 would not.

Required

1

explain why the fact that the supernova 1a has a consistent energy output matters in using them to determine that the universe is expanding.

Required

1

Notice that this is the same channel that we watched last week that introduced the concept of the oscillating universe or the cyclical universe. explain briefly what that theory was.

Required

1

The Oscillating universe theory originated in the mid 20th century, but was never considered a dominant theory (the big bang is considered a dominant theory). Einstein supported this theory for a while but determined that it was unlikely given what we understood about physics at the time. This was several decades before the discovery that expansion was accelerating in 1998, at which point support for the oscillating universe got significantly smaller. Why is expansion accelerating mean this theory is less accepted?

Required

1

Death of the universe time! remember what I said about worldview heavily influencing people? yup. do you have any questions?

Required

1

What assumptions about dark energy would you need to lead you to the big rip scenario?

Required

1

What assumptions about dark energy would you need to lead you to the big chill scenario?

Required

1

What assumtions about dark energy would you need to lead you to the big crunch scenario?
