Albert Einstein said, “As our circle of knowledge expands, so does the circumference of darkness surrounding it.”

[leonarddilworth]

Great question from Piers, and great answer fron Neil!!

[dedeeprice]

Well for now we know four per cent we're working on dark matter dark energy

The problem with it is we can't really detect it. We can just see its effects

But maybe someday we'll be able to figure out a way to detect what it is and how it works

That's the wonderment of science

It's an always growing learning experience

[yoavnativ]

Keep in mind that's 96% that we KNOW we don't know. That is not mentioning all the things we don't know we don't know

[deweyplanck]

If you want to know where we stand in accumulative knowledge, don’t compare what we think we know to what our ancestors thought they knew. Compare what we think we know to the infinity of all there is to know in the universe. This tells us that we are not in a position to determine an answer to the question.

[mammawlee]

How exciting!
There is so much more to learn

[runingshoe]

I like to watch him because he doesn't act like he's bored when he's explaining something for the 400th time and we still fell like it's the first time he's explaining it to someone.

[DavidCrisp-rvjs]

We know half as much as what we don't know and we don't know half as much as what we do know

[AbzJuma]

We know 4% of what's going on and yet within that 4% we cant find a universal theory of everything that ties the equations together.
So I'd say maybe we know 5% of the 4% and still another 95% to know of the 4%

[cjgameon]

We'll NEVER uncover the unknown deep mysteries of the universe. NEVER.

[jso]

4% is too huge to quantify our ignorance😢... But to little to quantify our arrogance😮😮

[xxACIDVIRUSxx]

A quick and correct answer would have been “we don’t know anything” because we don’t know if there’s even an end to what we can see so it’s fair to say exactly that!

[cezar-antoniocrintea]

Well actually with al due respect to Mister de Grasse we actually know less than 4% because we don't know all there is to know in biology for instance.

[buzzbrutusexcelsior]

If the universe is ever expanding into infinity. Wouldn't 4% of infinite also be infinite?

[adamd]

Take 4% of what you said and I think you will be closer

[stanwebb]

As soon as we know the answer to the dark matter and dark energy then we will be able to travel at Dark E/M speed and the speed of light will be footsteps to rocket speed!!!!

[ClockworkGearhead]

Simple answer, "We don't know how much we don't know."

[gmxnhvw]

That's the smartest thing Neil ever said

[prxZen]

We are _aware of the 4% of _*_conceptual fields_*_ wherein_ we hold_*some (!)* knowlege and understanding of that field.

We haven't read and understood 4% of the book - we're aware of and know _some unknown percentage_ of, 4% of its chapters.

[bencevastag]

What we know is a drop and what we dont know is the ocean
