dark matter part of the brain

[Walela]

I read that dark energy/matter makes up about ninety percent of the universe. I got to thinking a person only uses ten percent of their mind at best. Is the rest of the brain filled with this universal substance called dark energy?

Just curious at to what others think of this. Never thought of it before today. Now I am curious.

this is my first day on this forum and not sure where to put a question of this type.

It is a fascinating and strange concept to perceive a person as ninety percent dark energy/matter.

'The most recent WMAP observations are consistent with a Universe made up of 74% dark energy, 22% dark matter, and 4% ordinary matter' Wikipedia

The Universe consists of 74% dark energy and 22% dark matter. The Universe is not a far away object. Everything that exists is part of the Universe so would it be accurate to state everything in the universe contains 74% dark energy and 22% dark matter.

Everything consists of energy. Atoms are not solid. There is a lot of space between atoms. If dark energy exists in spaces would it not also exist in these spaces as well.

Could it be this dark energy that maintains the spaces in the atoms and the spaces inbetween the atoms?

I am just plain curious about this. It is a great topic for discussion!

Hi, Walela, and welcome to the BAUT.

It's a common misconception that a person uses only 10% of their brain. IIRC the visual cortex accounts for at least that much and being visual creatures we use the whole thing. The 10% figure might actually be how many neurons are firing at a given time.

Hey I used to live in Grants Pass!

G,day Walela. Get ready for some brain food.

Your question seems to imply that the 90% dark matter exists inside all cells. I haven't heard of that before.

But hey .... that doesnt mean too much.

The Master (albeit, the Master from a different message board) speaks on Do we really use only 10 percent of our brains?

Welcome to the forum, Walela.

I'd always assumed that all the dark matter was "out there" millions of miles away. I guess if it did form 90% of our brains, it would be fairly easy to detect. I think one of the things about dark matter and dark energy is that they are not detectable by our instruments, so I guess that even if there is such matter or energy in our locality, they are unlikely to be interacting significantly with normal matter (otherwise their presence would be obvious).

It may depend on the definition of "use". An interstellar spaceship may have 99% of its mass devoted to propulsion leaving one percent for the crew to "use". I would still say that it's all used.

But wrong. That's sort of like saying that any rock in the ocean has the same elemental composition as seawater.

I think it's fair to say that the vast majority of matter in the solar system is in baryonic (normal) matter, not dark matter. I guess it's possible that dark matter particles go through us every now and then, but how often does this happen, I have no idea.
