Why do astronomers theorize that there is dark energy in the universe?
There are several pieces of evidence for dark matter. For example: * Our galaxy, and many other galaxies, rotate way too fast for the amount of known matter. * Evidence from gravitational lensing.
Which is thought to be more prevalent in the universe dark matter or dark energy?
Dark energy. The current estimates for the distribution of mass/energy in the Universe are approximately: 68% dark energy 27% dark matter 5% baryonic (i.e. "normal") matter
What is the big idea for space and time?
The big idea for space and time is that the universe contains matter. Gravity and energy influence the formation of galaxies, and all matter of the universe.
Scientists classify everything in the universe as?
If they are astronomers, they classify everything as 'interesting'. I think the answer may be something like "matter or energy". In fact, according to Relativity Theory, mass (of matter) and energy are in many ways equivalent. "Mass-energy" is a term often used to refer to this fact. Pretty well everything in the Universe is matter or energy,
Is mass constant in all three states of matter?
By definition, the mass of a certain amount of substance is a constant regardless of the state it is in. But you should realize that there are actually four, not three, states of matter. Matter in the ionized state is called plasma, which comprises 99.99% of all visible matter in the universe.
Compare the amount of visible matter in the universe with the total amount of matter and energy?
4% Visible Matter (Atoms) 23% Dark Matter 73% Dark Energy
What state of matter is most abundant in space?
Plasma. It makes up more than 99% of visible matter in the universe, and most of the invisible matter.
What is the same about dark energy and dark matter?
there are the energy that mostly makes up this universe and its had been here since the beginning of the universe and also they are invisible.
Most of the visible universe if made of?
Most of the visible universe is made up of hydrogen and helium. These elements were formed during the Big Bang and make up about 98% of all visible matter in the universe.
What Matter in the universe that is undetectable but has mass is called?
Dark matter. It is theorized to make up approximately 27% of the universe's total mass-energy content. Its presence is inferred from its gravitational effects on visible matter.
What things are matter?
matter must have mass and volume.though it may be visible or invisible.
Looking at something let's say a chair how much of it is stuff matter visible and how much of it is non-stuff non-matter invisible or in anything what's the ratio of stuff to non-stuff?
The chair is primarily composed of visible matter, such as wood or metal. The invisible components would include the space between atoms and any energy associated with the chair, like electromagnetic fields. The ratio of stuff (visible matter) to non-stuff (invisible components) in the chair would be predominantly skewed towards the visible matter, with only a small fraction being the invisible components.
Is there a lot of dark matter in the universe?
Depends what you mean by "a lot." The gravitational effect of dark matter -- whatever the stuff happens to be -- is about six times greater than that of all the visible matter in our Universe.
What color is dark matter?
Dark matter is not visible to the naked eye and does not emit, absorb, or reflect light, so it does not have a color like visible matter. It remains invisible and undetectable through traditional telescopes, which is why it is called "dark" matter.
Does invisible matter takes up space?
Invisible matter, such as dark matter, does not interact with electromagnetic radiation and therefore cannot be seen or detected with telescopes. However, it is believed to take up space and have gravitational effects on visible matter in the universe.
What percentages of universal mass are claimed by dark energy dark matter and visible matter?
About 95.7% of the universe is dark matter, and the remaining percent (4.3%) is made of normal matter, plants, gases and such.
Why is it that call a collection of matter that does not interact with anything else in the universe?
The term for a collection of matter that does not interact with anything else in the universe is "dark matter." It does not emit, absorb, or reflect light, making it invisible and difficult to detect directly. Scientists infer its existence based on its gravitational effects on visible matter and the large-scale structure of the universe.
