The bottleneck of theoretical scientific breakthroughs is somewhat like a layer of window screen.
This layer is highly concealed and possesses two properties: tenacity and fragility.
Breaking through the bottleneck essentially means tearing this window screen.
With the right approach and direction, this layer of screen can be as fragile as paper.
But if you go the wrong way, it becomes a barbed fishing net for capturing whales, both robust and sharp, capable of cutting one severely and causing instant death.
Once you tear the screen, you can see the vast world inside.
If you can't break it, you would be lingering outside the door of truth for years, unaware of how close you ever came to it.
However, humans are ultimately a social group. Once the number of people with prior knowledge reaches a certain extent, small-probability events will become inevitable.
