An alternative universe is a hypothetical world outside of our own, depicting a different way in which the universe could function.
The new movie was in an alternative timeline. A alternative universe.

Usually an "alternative energy source" is one that is not now a major contributor to our energy supplies. That would make "alternative energy" anything that is not based on fossil fuels of one sort or another. Some people exclude nuclear energy from the "alternative" universe
That is a theory that, while the Universe expands, new matter is created (at a very slow rate); the final result is that the Universe looks the same today as in the past. This is an alternative to the Big Bang theory (while acknowledging the expansion of the Universe); however, it contradicts more recent observations. In the past, the Universe was indeed quite different from today.
There are some mathematical theories that indicate that other alternative universes may exit; however, we cannot detect them at this time.
It's not clear what kind of alternative universe history book you're reading, but in this universe Truman did use the atom bomb against Japan.
One early idea about the creation of the universe is the Steady State Theory, which suggests that the universe has always existed and will continue to exist indefinitely without any beginning or end. This theory was proposed as an alternative to the Big Bang theory but has since been largely discredited by the observational evidence.
The Steady State Hypothesis WAS the only SCIENTIFIC alternative to Big Bang Cosmology. It is now been rejected by all but a fringe of scientists. No other hypothesis makes any serious claim to scientific support.
There is no evidence that Parallel Universe exists, but doesn't mean that it doesn't exist. Accord of the law of Physics, yes Parallel Universe can exist. However if Parallel universe does exist, it will benefit to because when our universe come to an end, the only way to survive is to escape our universe to parallel universe.
The Big Bounce theory suggests that the universe expands and contracts in a continuous cycle, with each cycle ending in a "big crunch" followed by a new "big bang." This theory is an alternative to the Big Bang theory and proposes that the universe has no beginning or end.
The pulsating theory of the universe, which suggests that the universe undergoes cycles of expansion and contraction, was notably proposed by the Indian physicist Jayant Narlikar in the 1960s. He, along with other cosmologists, developed this idea as an alternative to the Big Bang theory. The concept posits that after each expansion phase, the universe could collapse back into a singular state, potentially leading to a new expansion phase.
Some alternative theories to string theory include loop quantum gravity, brane theory, and quantum field theory. These theories propose different ways to explain the fundamental forces and particles in the universe, without relying on the idea of tiny vibrating strings as the building blocks of everything.
