Are the existence of matter and energy life's ONLY mysteries?

There's more gravity in our universe than there should be, based on the amount of matter we can account for.

The current leading hypothesis is that dark matter accounts for the excess gravity, though I think your point is we don't really know what dark matter is or whether it exists, though hypotheses abound.

The two explanations I've heard are dark matter or a parallel universe whosw gravity is basically spilling over into our universe.

I think the hypothesis about gravity leaking into another dimension is generally a conjecture used to explain why gravity is so curiously and incredibly weak compared to the other fundamental forces.

There is no such thing as 'excess gravity', Sybil. You are bullshitting again.

Gravity is measured as Newtons per kilogram, N/kg

Nope. Gravity has no quantity. You are talking about mass and how it's affected by gravity, not gravity itself. There is no unit N/kg. You obviously don't even understand what a Newton is as a unit of measurement.

You are bullshitting again.

Earth's gravitational field has a value of approximately 9.8 N/kg everywhere at or near the surface, and only slightly less in near Earth orbit.

No such unit, Sybil. Go learn what a Newton is.
You are still trying to equate the effect of mass in gravity to gravity itself, which HAS NO UNIT OF MEASUREMENT! You are also now ignoring Newton's law of gravitational attraction.

You are bullshitting.

what;s the dominant force in your life? She-power?

A field, by definition, has a value at every point in space. Since gravity is a vector field, it also has a directionality as well as a magnitude at every point in space.


Boston University Department of Physics

"A field is something that has a magnitude and a direction at every point in space. Gravity is a good example. The magnitude of the Earth's gravitational field is 9.8 m/s^2 (near the Earth's surface)."

NASA: "Dark matter provides the surplus gravity."

European Organization for Particle Physics: "Something we have yet to detect directly is giving galaxies extra mass, generating the extra gravity"

Scientists first suspected dark matter’s existence over 80 years ago when Swiss-American astronomer Fritz Zwicky observed that galaxies in the Coma cluster
