I am not against continuing the research of extraterrestrial signals. I am against using increasingly powerful telescopes for this. That...

I focused on another aspect. That even if the telescope's sensitivity is the same as that of a ground-based one, there will be less risk...

Rather, to increasing the power of telescopes than to change their location. On Earth, is greatly hampered by terrestrial interference...

I read that there are ideas to build a radio telescope on the far side of the Moon. There will be no anthropogenic noise there.

Fast radio bursts, for example.

It seems to me that this will be too expensive and will require a lot of resources, and possibly territories.

It will be more gradual and less clear-cut, and will take many decades. By that time, the climate change and nuclear threat may already...

If on average there is one radio-emitting civilization in the entire galaxy, then on average, waves will only reach us from one (there...

But if this is a short period by astronomical standards, then there will be very few such civilizations, perhaps one in the entire...

Probably, advanced civilizations do not use radio communication. Then there will be a false idea of our loneliness, from which there...

I haven't written about science in general, but there are areas that are either unproductive or have negative side effects. For example...

But the whole trick here is that we are the external observers, not the little people falling into the black hole. For us, time does not...

I meant created by alien civilizations. Not humans, of course.

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation...

According to the General Theory of Relativity, time does not pass on a black hole, which means that processes they don't work either. As...
