Gnome universe lab: which of the following was NOT a galaxy in our expanding universe lab video

Gnome Universe Lab: According to the expanding universe lab, what two variables are compared on the Hubble Diagram Graph. 2 answer choices

Gnome Universe Lab: What was the slope of the Hubble Diagram Graph called/represent?

Shape of space Video: What is the curvature of the universe like according to the best data we have currently.

Shape of space video: What happens to two parallel beams of light in FLAT space

Shape of space video: What happens to two parallel beams of light in Positively curved space. (super potato)

Shape of universe video: What are the TWO ways of measuring the curvature of space?

END OF UNIVERSE VIDEO: Which of the following is NOT a way the universe could end.

END OF UNIVERSE VIDEO: what are the TWO things opposing each other that will determine how the universe ends?

End of Universe Video: What is the most likely outcome/end of our universe?

a fundamental force of nature between two objects that is proportional to the product of their masses and inversely proportional to the square of the distance between their respective centers. It depends on nothing else.

the energy of empty space to expand and causes the universe as a whole to expand, opposes gravity on a universal scale.

slope of the line relating the speed of the galaxies away from each other and their distance apart from each other. Allows for the calculation of the age of the universe, also the slope in our GNOME universe lab video.

material that does not emit any light (or not detected yet), but has a significant gravitational effect.

a universe with too little matter (gravity) to stop the expansion (it has an ``open future''). Dark Energy wins; Results in Big Rip

a universe that stop expanding only after an infinite amount of time (a special case of an open universe). Gravity and Dark Energy ar balanced; Results in Big Freeze.

a universe with enough matter (gravity) to eventually stop the expansion and recollapse (it has a "closed future"). Gravity beats Dark energy; Results in Big Crunch

the universe stops expanding at an accelerating rate but doesn’t contract or expands at a constant non accelerating rate, slowly all energy is converted to heat, no more useful energy conversions and the universe freezes to death. Most likely end to universe according to data currently.

The universe starts shrinking then crushes to an infinitesimally small space and possibly spawns a new big bang - least likely to happen end according to data currently.
