AI Thread Summary
Dark matter is theorized to be matter from another universe, interacting with our universe solely through gravity. Participants in the discussion emphasize the importance of adhering to mainstream scientific theories rather than personal speculation. Various hypotheses exist regarding why dark matter interacts only via gravity, including concepts of "exotic" matter, unseen normal matter, and potential modifications to gravity. The conversation encourages exploration of established scientific literature for further understanding. Mainstream science remains the focus of the discussion, steering clear of personal theories.

I think that dark matter is matter from an other universe that we can only interact with through gravity. Does anyone have a hypothesis for why does the matter interact with us only with gravity and not with any other of the fundamental forces like electromagnetism etc.
Thanks!

Personal ideas, speculation, and theories are not allowed here at PF. We like stick to mainstream science.

Yes, there are many hypotheses. Check out this wikipedia article if you'd like to know what those are. Possibilities include "exotic" matter, unseen normal matter, and modifications to gravity.

Thanks, I will try to stick to mainstream science.
 

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?'

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 'Can the signal WOW be explained by the maser effect?'

This hypothesis of scientists about the origin of the mysterious signal WOW seems plausible only on a superficial examination. In fact, such a strong coherent radiation requires a powerful initiating factor, and the hydrogen atoms in the cloud themselves must be in an overexcited state in order to respond instantly. If the density of the initiating radiation is insufficient, then the atoms of the cloud will not receive it at once, some will receive it earlier, and some later. But then there...
