Speed of Dark Matter: Exploring Universe Creation

In summary, there are theories about the creation of the universe but it is uncertain whether it had a beginning or has existed for an infinite amount of time. Dark matter follows timelike worldlines like ordinary matter, contrary to the belief that it can break physical laws and go through spacelike intervals. Therefore, there is no speed limit or energy density limit for dark matter.

I have been wondering about how the universe created itself from nothing and it seems in spacetime, the time dimension must have come first followed by multidimensional space. Following this, matter and dark matter must have been created. While matter and dark matter both underwent timelike expansion, dark matter had the liberty to break physical laws and go through spacelike intervals. IF that is true, what is the speed limit and energy density limit for dark matter?

It isn't. Dark matter follows timelike worldlines just like ordinary matter.

I'd like to correct the misconception that the universe was created from nothing. Current theories regarding the origin of the universe are tentative guesses at best. Despite what you commonly hear or read, we have pretty much no idea if the universe even had a beginning or if it's existed for an infinite amount of time.
 

Related to Speed of Dark Matter: Exploring Universe Creation

1. What is dark matter?

Dark matter is a type of matter that does not interact with light or other forms of electromagnetic radiation. It is only detectable through its gravitational effects on visible matter.

2. How is the speed of dark matter measured?

The speed of dark matter is measured indirectly through its gravitational effects on visible matter. Scientists use various techniques, such as studying the rotation of galaxies or observing the bending of light from distant objects, to determine the speed of dark matter.

3. What role does dark matter play in the creation of the universe?

Dark matter is believed to have played a crucial role in the formation and evolution of the universe. Its gravitational effects helped to shape the distribution of matter in the early universe and continue to influence the growth of galaxies and galaxy clusters.

4. How does the speed of dark matter affect the expansion of the universe?

The speed of dark matter has a significant impact on the expansion of the universe. It is thought to contribute to the overall mass and energy content of the universe, which affects the rate of expansion. As the universe expands, dark matter also becomes more spread out, resulting in a decrease in its speed over time.

5. What are the current theories about the origin of dark matter?

There are several theories about the origin of dark matter, but none have been proven conclusively. Some suggest that it is made up of unknown particles, while others propose alternative theories of gravity. Scientists continue to study and gather evidence to better understand the origins of dark matter.
