What is the relationship between virtual time and black holes?

[Sarahchichi]

Today, I read a book which is written by Stephen Hawking. I have something don't understand.

We all know that REAL TIME must go from the past to the future,but how about VIRTUAL TIME? The book says that Virtual Time can be increased or decreased in a three dimensional space. I wonder why??

It syas that the information inside black holes can be saved up in a two dimensional space. Afterwards, these information can be recombined to form a three dimensional object. I wonder will these information combines to form stars, planet??

If you have any comments, do reply me.

Thanks,
Sarah

You're obviously referring to imaginary time in Hawking's The Universe in a Nutshell, page 60-65. Rather complex stuff. See e.g. this: http://www.iiap.res.in/answers/gphysics.html#five
Probably above your head (for me too ).
I've seen a more down to Earth explanation here:

Still quite speculative...

Hello Sarah,

Thank you for sharing your thoughts on the concept of virtual time and black holes. It is indeed a complex and fascinating topic to explore.

To answer your question about virtual time, it is important to understand that it is a theoretical concept used in physics to describe the behavior of particles at a very small scale, such as in quantum mechanics. In this context, virtual time is not the same as real time that we experience in our daily lives. It is a mathematical concept that helps us understand the behavior of particles in a three-dimensional space.

As for the idea of information inside black holes being saved in a two-dimensional space, this is a theory proposed by Stephen Hawking called the "holographic principle". It suggests that all the information about an object that falls into a black hole is stored on the surface of the black hole in two dimensions. This information can then be recombined to form a three-dimensional object, but it is still just a theory and has not been proven.

As for whether this information can form stars or planets, it is not yet known. The information stored in a black hole is in the form of quantum states, which are very different from the matter that makes up stars and planets. It is still an area of ongoing research and we may learn more about it in the future.

I hope this helps clarify your doubts. Happy reading and keep exploring the wonders of the universe!
