Do multiverses follow the same laws of physics?

In summary, Lawrence Krauss discussed the concept of the universe originating from empty space, which was supported by the idea that nothing is not truly nothing. He also questioned whether multiple universes would abide by the same laws of physics, to which the speaker believes they likely would due to the natural law of instability in empty space. The speaker acknowledges that this is a difficult topic to discuss as the existence of multiverses is still unknown.

Recently I was watching Lawrence Krauss on YouTube talking about the universe originating from empty space, which seemed to make sense when he described that nothing isn't really nothing.

Then he later in the video he asked the question of whether multiverses would also follow the same laws of physics.
My thoughts on this are that they likely would since the instability of empty space seems to already portray a law of nature. Perhaps even the law of gravity itself existed before our universe did?

Please do share your thoughts, thanks.

Here is the video :

well my initial thoughts are ...
Since we don't even know if multiverses exist, it's pretty difficult to know what physics they follow
It's almost a pointless discussion

Related to Do multiverses follow the same laws of physics?

1. Do all multiverses have the same fundamental laws of physics?

The answer is not definitively known, as there is currently no way to observe or test other universes. However, some theories suggest that the laws of physics may vary in different universes, depending on factors such as the number of dimensions or the strength of fundamental forces.

2. Are the laws of physics in each multiverse consistent with each other?

Again, this cannot be confirmed without direct observation. However, it is possible that different universes may have slightly different variations of the same laws, or even entirely different sets of laws altogether.

3. Can we ever prove the existence of other multiverses through physics experiments?

At this time, there is no way to directly detect or measure the presence of other universes. The concept of multiverses is still largely theoretical and has yet to be proven through scientific experimentation.

4. How do the laws of physics in our universe compare to those in other multiverses?

Since we can only observe and study the laws of physics in our own universe, it is impossible to accurately compare them to those in other multiverses. However, we can use mathematical models and theoretical frameworks to make predictions about how the laws of physics may differ in other universes.

5. Is there a limit to the number of multiverses that can exist?

This is a highly debated topic among scientists. Some theories suggest that there could be an infinite number of multiverses, while others propose that there may be a finite number or even just one. Ultimately, the answer to this question is still unknown and may never be fully understood.
