Only the coasting model makes the assumption that the universe's expansion pace never changes.
The current expansion of the cosmos is predicted by all four hypotheses.
Only the recollapsing model foresees the eventual contraction of the universe.
The average mass density of the cosmos is predicted to be exactly the critical density only under the critical model.
The cosmos is only predicted to be expanding more quickly than it did in the distant past by the accelerating model.
Cosmologists use observations of radiation released soon after the Big Bang to determine the expansion rate, often known as the Hubble constant.
Since the unexpected finding that the universe's expansion is speeding up in 1998, cosmologists have incorporated repulsive dark energy into their theory of cosmic development. The Hubble constant's inconsistent values might be resolved by early dark energy, an additional amount of dark energy present in the early cosmos. This early dark energy would have accelerated the universe's expansion by exerting external pressure.

As new energy sources have been developed, the energy
consumption in the history has changed significantly.
There were some new forms of energy developed, such as fossil
fuels like petroleum, natural gas, and coal which provides energy for 87% of
US.
Answer:
x = 2
Explanation:
if it was -7 = the square root of both 2x-9 together, it would be false.
if it was square root of just 2x in the equation, the answer is:
x = 2
°°°°°°°°°
-7 = √2x - 9
-√2x = -9 + 7
√-2x = -2
√2x = 2
2x = 4
x = 2
