Matter with different constants

In summary, the conversation discusses the concept of a multiverse and the possibility of matter from one universe traveling to another universe through a wormhole. It is suggested that matter cannot carry its properties and constants with it and that the bridge between universes would have to be made of space. The potential existence of "domain walls" and their lethality is also mentioned. It is then stated that there is no scientific justification for the existence of a multiverse. The conversation ends with a question about the probability of another universe having the same constants and laws as ours, to which the responder states that there is no justification for assuming the existence of another universe.

If the physical constants vary from universe to universe in a multiverse, then if matter from this universe were to somehow go into another universe, say through a wormhole, what would happen to it? Would it disintegrate, or somehow behave strangely? What if the
cosmological constant varied in the other universe?

I suspect that space and matter arise from the same fundamental constituents----that is, geomety and matter are emergent, and have the same underlying dynamics and degrees of freedom.

in that case the properties of matter are intrinsic in any volume of space-----the constants you mention are built into space itself.

in that case matter cannot carry its properties or constants with it and travel thru a tunnel to some domain with different matter. the bridge would have to be made of space, and whose constants would the space have?

In some exotic inflation scenarios there are "domain walls" dividing domains with different physics (different constants, laws perhaps) which travel at the speed of light and which are LETHAL. If a domain wall passes thru your galaxy, you've had it. AFAIK such exotic inflation scenarios do not have much justification and are mostly just piquant fantasy.
======================

The above is just my own take on it, you asked a speculative question. but the basic problem is that no one so far has offered any scientific justification for assuming that a "multiverse" exists. That is, there is no scientific reason to think that the universe consists of domains with different laws or different physical constants.

People toy with the idea if it appeals to their imaginations. But do you know any justification for it? If so, please tell us!

I see no justification for assuming that a different universe exists, therefore the question of probability doesn't mean anything to me.

Do you understand what I am saying? If there is no other universe then what probability are you asking about?
 

1. What is matter with different constants?

Matter with different constants refers to the physical substances that make up our world, such as atoms, molecules, and compounds, that have varying properties and characteristics due to the different constants that govern their behavior.

2. What are some examples of matter with different constants?

Examples of matter with different constants include elements on the periodic table, such as carbon, oxygen, and gold, as well as compounds like water and table salt. These substances have different physical and chemical properties, such as melting point, boiling point, and reactivity, due to their unique molecular structures and the constants that influence their behavior.

3. What are the different constants that affect matter?

There are several constants that affect matter, including the speed of light, Planck's constant, the gravitational constant, and the electromagnetic constant. These constants determine how matter behaves and interacts with other substances, and they are essential for understanding and predicting the behavior of matter in various conditions.

4. How do different constants impact the properties of matter?

The different constants that govern matter have a direct impact on its properties. For example, the speed of light determines how quickly light travels through matter, while the gravitational constant affects the weight and movement of objects. The electromagnetic constant plays a crucial role in the behavior of charged particles, such as electrons, in matter.

5. Why is it important to study matter with different constants?

Studying matter with different constants is crucial for understanding the fundamental laws and principles that govern our world. It allows us to make predictions and develop technologies that harness the properties of matter for various purposes, such as creating new materials, developing medicines, and exploring the universe. Additionally, studying matter with different constants helps us better understand the origins of our universe and the complexity of the world around us.
