Can Matter Be Transferred Between Universes?

AI Thread Summary
The discussion centers on the speculative nature of transferring matter between universes, with participants noting that there is currently no evidence to support such a concept. It is suggested that the universe can be viewed as an isolated system, making the idea of matter transfer implausible. Some participants express a fascination with the possibility of multiple universes, acknowledging past misconceptions about the universe's scale. The conversation also touches on different definitions of "universe," with one perspective viewing it as a closed system and another considering it as all-encompassing three-dimensional space. Ultimately, the consensus is that without evidence, the question remains unanswered.

i wish to know if matter can be transferred from one universe to other universe? does our universe have valve like thing to let the matter in or out of the system?

"Other universe" is highly speculative and is not supported by ANY evidence so your question has no answer.

I think an isolated system is the correct way of thinking about it.

What he said, but I sometimes like to speculate that there are many Universes, since the beginning of time we've been wrong about much of the Universe, and when I like to think about it, I say why not, it could be a possibility (Don't count on my words because there is no proof for this), we used to think there was just the solar system, but nope there's billions which is probably an understatement! Also then we discovered that we live in an island of stars which is our galaxy, that was only 1 of billions! So I like to think, why can't there be more than 1 universe or even billions, where they can transfer energy from one universe to the other!

Anyways, I'm getting ahead of myself and phinds has answered your question.

There are two ways of defining "universe". One is anything that we can measure or affect. So, by that definition, the universe is a closed system.

Another way to define the universe is to say that it is the entire three-dimensional space across all of time. That what you're thinking of when you ask your question. I recall one alternate theory to the Big Bang that posits two 3D universes colliding.

From what I read, most basic particle physics seems to live in "Hilbert Space" with as many dimensions as you need. This would argue against little exchanges with other 3D planes - since whatever is holding us to 3D would likely collapse any matter local to our 3D space back into our space right away.
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Could fast radio bursts be alien radar signals?'

Both have short pulses of emission and a wide spectral bandwidth, covering a wide variety of frequencies: "Fast Radio Bursts (FRBs) are detected over a wide range of radio frequencies, including frequencies around 1400 MHz, but have also been detected at lower frequencies, particularly in the 400–800 MHz range. Russian astronomers recently detected a powerful burst at 111 MHz, expanding our understanding of the FRB range. Frequency Ranges: 1400 MHz: Many of the known FRBs have been detected...
