No, love isn't a fanfic. Fanfics are imaginative creations within a specific fictional universe. Love is a fundamental aspect of human experience that transcends such fictional constructs.
A sucky love story on VK could be one with weak character development. If the characters don't grow or change in a meaningful way, it can be a letdown. Also, a lack of emotional depth or believable conflicts can make it not so great.
One popular theme is the exploration of the relationship between the main characters in different scenarios. For example, 'what if' situations that didn't happen in the original book.
Fanfiction.net might also have some. However, the quality can vary a lot more compared to AO3. You'll need to be a bit more patient when searching through the results there. But it's still worth a shot if you can't find what you're looking for on the other platforms.
The concept of time-travel was theoretically possible, but it required certain conditions to be met.
The theory of traveling through time and space was mainly based on Einstein's theory of relativity, the most famous of which was the "time expansion" theory. This theory suggests that time will accelerate as the speed of the object and the strength of the gravitational field increase. Therefore, if the object can travel through time, the time they pass will be slower than their current position.
If time travel is true, then we can achieve it in some ways. For example, we can use a super accelerator to accelerate the passage of time and allow objects to "travel" through time. Another way is to change the way time passes in the present, such as using a time machine to bring objects back to the past.
However, there were other conditions that needed to be met to travel through time and space. For example, we need to be able to control time and space, otherwise we'll only be able to bring things back to the past but not to stay in the present. We also need to consider the effects of gravity because gravity might prevent us from traveling through time and space.
Therefore, traveling through time and space was theoretically possible, but it required certain conditions to be met. Although we don't have the technology to travel through time yet, scientists have been exploring this field and hope to find a way to solve this problem.
