What else can I help you with?
Will the universe expand forever will it stop or will it reverse itself according to the general theory of relavitiy it all depends on how much matter is within the universe this all depends on what f?
According to the general theory of relativity, the ultimate fate of the universe depends on its density of matter and energy. If the density is above a certain critical value, the universe will stop expanding and eventually collapse in a "Big Crunch." If the density is below this critical value, the universe will continue to expand forever. Current evidence suggests that the universe's expansion is accelerating, indicating a low density and a future where it expands indefinitely.
What does dark matter have to do the critical of the universe?
Dark matter is actually Melanin. Melanin is the pigment that gives us color. Black people have 12 Melanin centers in their brain, while white people only have 2. Melanin allows us to covert the Sun's light waves into Sound waves, which gives the universe its shape and us the ability to shape the universe through the law of vibration.
What does measuring the amount of deuterium in the universe allow us to set a limit on?
Measuring the amount of deuterium in the universe allows us to set a limit on the density of normal matter in the universe. This is because the production of deuterium in the early universe is sensitive to the density of ordinary matter, providing a way to estimate the total amount present.
How is the universe expanding even if atom can't be created?
It is space that is expanding. The amount of matter doesn't necessarily increase. This means that the average density of the Universe is decreasing.It is space that is expanding.

Dark energy seems to be accelerating the expansion of the universe causing what?
That means that the Universe expands faster and faster. It causes the Universe to grow, and the general density of matter in the Universe to decrease over time.
Compare and contrast average density and critical density?
the average density is the total amount of matter in the universe, whereas the critical density is about 10 to the -26th power kg/m cubed (to the third power), the dividing point between a closed or open universe.... :)
How dense is dark matter?
This can be answered in two steps: 1) What is the average density of all gravitational matter in the Universe? It has surprised astrophysicists that this density is extremely close to the "critical" density; above which our Universe eventually collapses in itself, and below which our Universe expands forever. This critical density is about 5 x 10^-30 grams per cubic centimeter. 2) How much of the mass of the Universe is NOT dark matter? What shocked astrophysicists even more was determining that the average density of all luminous matter was only about 20% of the critical density. Thus, about 80% of the measured density of our Universe can be accounted for via stuff that gives off light. The ratio of hydrogen to helium to deuterium in our Universe puts an upper limit on the density of baryonic matter in our Universe. This calculation also shows that the density of baryonic matter can not be more than about 20% of the critical density. These two, completely independent calculations of the amount of luminous and of baryonic matter -- the stuff we understand -- in our Universe have left scientists with little choice but to conclude that 80% of the gravitational mass in our Universe is composed of something we don't understand. And that's why we call it "dark" matter. Since the Universe has a density of 5 x 10^-30 grams per cc, and only 80% of that is dark matter, then the latter's average density is about 4 x 10^-30 grams per cc.
Why are measurements of the current density of the universe important?
Measuring the current density of the universe is important because it helps us understand the distribution and composition of matter in the universe. By studying current density, we can learn about the evolution and structure of the universe, including the role of dark matter and dark energy in shaping its properties. This information is critical for developing accurate models of the universe's past, present, and future behavior.

Is the universe the creation of matter or the expansion of matter which is pre existing?
The matter that existed since the Big Bang is expanding. A few decades ago, a "steady-state" theory was popular; according to it, matter was created as the Universe expanded, thus maintaining the matter density in the Universe constant. However, observational evidence did not support this theory.The matter that existed since the Big Bang is expanding.

How can you use properties of matter to determine the density?
The density is the ratio mass/volume.
How do you determine the density of matter?
Usually you would use the basic definition of "density": just divide mass by volume.
Dark energy seems to be accelerating the expansion of the universe causing what?
That means that the Universe expands faster and faster. It causes the Universe to grow, and the general density of matter in the Universe to decrease over time.
How do you use properties of matter to determine density?
To determine density, you measure the mass of a substance using a balance and the volume using displacement or geometric calculations. Density is calculated by dividing the mass by the volume. This property reveals the amount of matter packed into a given space and can help identify the substance based on its density value.
