What do you think how much percent do we know today about how

1%

You should ask this on /sci/. Around 10%, the rest is so called Dark Matter, which is non-barionic, this can't be seen, but interacts somehow with the "visible" world through gravity.
For instance, there is a way to detect supermassive rings of cosmological strings when the light passes through them by how they curve the light.

Some tiny fraction of 1%.

*it can't be seen

I am about to do so but I have to wait till I can create a new thread.

You probably will receive the same answer, about 10% of observable Universe is our "regular" barionic matter, whose physics are described to a decent degree.

Here in /his/ you will only find dramatizing philosophers who will talk about "less than 1% etc". /sci/ is only marginally better.

However, imo, science history and especially space exploration history is the best and the most heroic part of human history.

What I think is following.

We have been able to compare our sun with other stars for some generations. We now are comparing our planet into other planets found in other star systems. But it still is a mystery when and how we would be able to compare ourselves with other life forms out there.

Less than 1% is more correct though.

People can say only x% of universe is visible and we know that, however the universe is a small subset of the quantum fields.

A real answer would be less than 0.00000000000000001%.
