What will cause the rate of expansion of the universe to slow down?
The expansion rate of the universe is determined by the mass of the things in the universe and the strength of the gravitational force. The universe would start to slow down if some new form of matter were to intervene which incresed the over all mass of the universe, or if there's some property of gravity that we don't know of, where at some threshold it actually becomes stronger.
What are the ripples in the cosmic background radiation?
The ripples in the cosmic background radiation, known as anisotropies, are tiny fluctuations in temperature and density that provide crucial insights into the early universe. These variations, detected in the Cosmic Microwave Background (CMB) radiation, are remnants from the Big Bang and reflect the distribution of matter and energy in the universe at that time. They help scientists understand the formation of large-scale structures, the properties of dark matter, and the overall geometry of the universe. Analyzing these ripples has been vital for cosmology, offering evidence for the inflationary model of the universe's expansion.
How does expansion and contraction of matter differ from a change in state of matter?
the matter always stays the same, expansion and contraction just means the matter is becoming more/less spread out from one another. A change in the state of matter is turning from solid-liquid-gas. The amount of matter always stays the same!
Is black hole a matter?
No, dark matter is not a black hole. Each one is a separate cosmic phenomenon. Use the links below to find out about each one.
What is meant by when cosmic dust goes unswept?
When cosmic dust goes unswept, it means that these small particles of matter, such as grains of ice and dust, remain in space without being cleared away or disturbed by other celestial bodies. Over time, cosmic dust can accumulate and contribute to the formation of cosmic bodies like planets and moons.

The expansion of matter upon heating is an example of a?
The expansion of matter upon heating is an example of a thermal expansion, which is the tendency of matter to change in volume, area, and length in response to a change in temperature.
What name do you give to the theory for the origin of the Universe?
The Big Bang Theory is the name given to the theory of cosmic expansion. The idea is of an ever expanding universe. It posits that at some point all matter in the universe was contained within one point.
Is expansion of matter due to expansion of particles rather than to increase particle spacing?
Expansion of matter is primarily due to an increase in the spacing between particles, rather than the expansion of individual particles themselves. When matter expands, the average distance between particles increases, leading to the overall expansion of the material. While individual particles may also exhibit some expansion due to thermal effects, the overall expansion of matter is more prominently driven by increased spacing between particles.
The expanding of matter when it is heated?
thermal expansion
What is called the fine particles of matter in outer space form cloud?
cosmic dust
Why do scientist think the universe will expand forever?
There is actually considerable debate about that. Some scientists believe that the universe (or at least, the part we can see!) is not massive enough to cause the current expansion to slow down and reverse, and other scientists believe that "dark matter" may provide enough mass to reverse the expansion.From a philosophical viewpoint, the idea of an "oscillating" universe - big bang followed by expansion, followed by contraction, followed by collapse, and repeat forever - is more appealing. But at present, the balance of the evidence seems to be against it.There is evidence that the expansion of the Universe has been accelerating. It is not known exactly why, and it is possible that the expansion may slow down again, but this doesn't seem very likely.
What caused the swirling matter to condense after the big bang?
At the start of the universe all the electrons were zipping around like crazy because everything was super hot. Then the universe expanded enough to cool down and all the building blocks of atoms slowed down enough to combine into elements. When matter is present it affects the fabric of space time to make gravity. Gravity pulls matter together and stars are born. The key elements for this is that the universe is cool enough, and there is enough time. One theory suggests that matter attracted other matter. Another theory suggests that dark matter pulled or pushed baryonic matter (normal atomic matter) together. Still another theory suggests that cosmic strings (flaws in space-time) create deep gravity wells and attracted matter that slowly coalesced into gas clouds, stars, and planets.
What is the process of thermal expansion?
Thermal expansion is the tendency of matter to change in volume in response to a change in temperature.
Does dark matter/energy responsible for the expansion of the universe?
Yes. Dark energy is responsible for the expansion of the universe.
