Radius of Universe, electrons, and strings.

In summary, the conversation revolves around the concept of motion of strings or particles giving rise to particles or universes, and the size differences between them. The accuracy of these statements is uncertain and further data is needed. There is also mention of the possibility of a Multiverse.

Motion of strings may give rise to particles? Size difference about,

E-35m/E-15m = E-20

Motion of particles gives rise to Universe (or Universes?)? Size difference about,

E-15m/E26m = E-41

Thanks for any help.

What kind of help. You made a couple of assertions, without any explanation, and asked no question.

I did include question marks %^). I don't know if those statements were true or if there any sense they are true %^(. Hoping these statements could be corrected or made more accurate by the minds of Physics Forums.

Thank you.

We are still unsure about the Universe size - waiting for data from the most distant corners.

Can we at least say our Universe is of a certain minimum size but that measurements don't exclude a much bigger size?

Thank you.

Are you asking if there is a Multiverse as well?

He could as well have asked about the recipe of cherry marmalade... I wouldn't bother replying to a thread starter who couldn't bother phrasing a post worth reading himself.

Ouch! Follow your own advice.

Thanks.

Okay... were you asking about whether or not we know of the Multiverse or not?
 

Related to Radius of Universe, electrons, and strings.

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

The current estimated radius of the observable universe is approximately 93 billion light-years.

2. How do electrons contribute to the size of an atom?

Electrons, being negatively charged particles, orbit around the positively charged nucleus of an atom. The number of electrons in an atom's outermost energy level determines its size, as electrons repel each other and create a larger space between the nucleus and the outermost electrons.

3. What is the significance of string theory in understanding the size of the universe?

String theory is a theoretical framework that attempts to reconcile the laws of quantum mechanics and general relativity. It suggests that the universe is made up of tiny one-dimensional strings, which vibrate at different frequencies and give rise to the different particles and forces we observe. It is still a developing theory, but it has the potential to provide insight into the fundamental nature of the universe and its size.

4. How does the radius of the universe change over time?

The radius of the universe is constantly changing, as the universe is expanding at an accelerating rate. This expansion is driven by dark energy, a mysterious force that makes up about 68% of the total energy in the universe. This means that the radius of the universe will continue to increase over time, and objects that are currently a certain distance apart will continue to move further away from each other.

5. What is the connection between the radius of the universe and the Big Bang theory?

The Big Bang theory is the leading scientific explanation for the origin and evolution of the universe. According to this theory, the universe began as an infinitely dense and hot singularity and has been expanding ever since. The radius of the universe at any given time is a direct result of this expansion, and studying the radius of the universe can provide insights into the early stages of the universe's development.
