Do i have this right now - mass of the universe

In summary, the mass of the universe is divided into three main categories: dark matter at 26.8%, dark energy at 68.3%, and ordinary matter at 4.9%. This ordinary matter is further broken down into 3.6% intergalactic gas and 0.4% luminous matter, such as stars. However, there is a missing 0.9% in the ordinary matter breakdown, which could potentially be made up of dead stars. It is not worth discussing the precise breakdown of planet mass in relation to the sun.

Do i have this right now -- mass of the universe

Edit.

The mass of the universe is divided thus. Dark matter = 26.8%

Dark energy = 68.3

Ordinary matter = 4.9%

The ordinary matter is made up of 3.6% intergalactic gas (nonluminous)

And 0.4% stars etc (luminous)

I hope i have as i am always +-1%

You are missing 0.9% in the ordinary matter breakdown.

You are missing 0.9% in the ordinary matter breakdown.

like the planets in our solar system...

Very doubtful. Planet mass is very much smaller than the sun.

The missing 0.9% could be dead stars, but I don't have the specifics.

Oh I just realized the original breakdown description is imprecise...

Dead stars seem like ordinary matter...and so does planet mass...

not worth discussing...
 

FAQ: Do i have this right now - mass of the universe

1. What is the current estimated mass of the universe?

The current estimated mass of the universe is approximately 3 x 10^52 kg.

2. How was the mass of the universe calculated?

The mass of the universe is calculated by measuring the amount of visible matter, dark matter, and dark energy present in the universe.
