Question

Match the theory to the statement that best describes it. 1. big bang. 2. steady state. 3.osscillating universe. 4. inflation Choices: 1.the most accepted theory on the origin of the universe. 2. it's like an inflating and deflating balloon that never stops. 3. all is the same and will always stay the same. 4.agrees with the big bang theory, but insists the universe expanded much quicker.

Answer 1

Explanation :

(1) Big bang : (1) The most accepted theory on the origin of the universe.

This theory shows the expanding of the universe from high density and high-temperature states.

(2) Steady state : (3) All is the same and will always stay the same.

Steady state means that the properties of any system remain the same always.

(3) Oscillating universe : (4) Agrees with the big bang theory but insists the universe expanded much quicker.

Oscillating universe theory is the result of big bang theory.

(4) Inflation Choices : (2) it's like an inflating and deflating balloon that never stops.  

In cosmology, cosmic inflation or deflation is just the expanding and contraction of the universe.

So, the statements and the choices are related as:

               (1)-(1)

              (2)- (3)

               (3)-(4)

               (4)-(2)

Answer 2

Answer:

1. big bang - the most accepted theory on the origin of the universe.

2. steady state -  all is the same and will always stay the same.

3. oscillating universe - it's like an inflating and deflating balloon that never stops.

4. inflation- .agrees with the big bang theory, but insists the universe expanded much quicker.

Explanation:

1. big bang - the most accepted theory on the origin of the universe. It describes that at entire matter of the universe was compressed at a single point (singularity). At time t =0, with big bang, the point started expanding.

2. steady state -  all is the same and will always stay the same. The steady state theory of universe suggests that matter is being continuously created in the expanding universe which leads to unchanged density of matter. Thus, at any given of time and place, the universe is basically same.

3. oscillating universe - it's like an inflating and deflating balloon that never stops. It is a theory that suggests that universe is oscillating between big bang and big crunch which means universe would expand and then contract.

4. inflation- .agrees with the big bang theory, but insists the universe expanded much quicker. The universe expanded very quickly during first fraction of second. Thereafter, the universe expanded at a lesser rate.
