The Scientific Revolution was one of the factors that caused the Enlightenment. However, it depends on which entities of the Enlightenment you are focusing on.
When we think of the Enlightenment, we tend to think of philosophers first. This is because the Enlightenment was not a purely scientific movement, but more of a wide-ranged intellectual time. Ideas from thinkers like Galileo, Copernicus, Isaac Newton, etc, were produced in the Scientific Revolution, and merely built off of in the Enlightenment.
You see, thinkers during the Enlightenment wanted to question the many beliefs that were set during the Dark Ages, which also meant going up against large, powerful opposition, like the Catholic Church. The ideas that came out of the Scientific Revolution gave Enlightenment thinkers the facts they would use when creating their theories. Armed with these facts, they could debunk the ridiculous theories that others had set in the past.
So finally, to answer your question, it is probable that the Enlightenment would have started nevertheless, but it is unlikely that the ideas of its thinkers would have made such an impact without the Scientific Revolution.
Hope it helps!
B. the world trade center and the twin towers and the Pentagon
The American Civil War is considered the first modern world for multiple reasons. Advances in technology made it possible to inflict mass casualties. Rifles were more accurate, took less loading time, and the bullets were more devastating in their effects. Earthworks were dug as barriers from direct gun and shellfire. Ironclad ships and the first submarines were used.
Other reasons that this war is considered the first modern war, was that it was possible, because of the railroads and telegraphs, to communicate in a timely manner, in different parts of the country. The war was widespread and communication was vital, whether it was to let someone know that they were getting new supplies of Enfield rifles, to alerting a commander that the opposition was changing position and heading to a new target.
Photography and reporting were extensive in this conflict, bringing the modern horrors of the battlefield into the homes of non-combatants. Everyone was effected or participated in the war. From the destruction of the South to the poor conditions of prison camps, this war touched almost everyone, in some way.
