Can only a Milky-way type of galaxy hold life at this age of the universe?

Kjelete · Dec 26, 2025

I`ve been reading about the Milky-way and galaxis, I suspect there`s been different types of galaxies before ours, which held life.

The universe ages, and changes, but the psychics are the same, light and warmth. The idea aliens have big eyes, are most probably nonsense since I think life wouldn`t evolve on a dark planet.

At this time of the universe, do you think only a galaxy shaped like ours, can hold life? Then in a distance future, galaxies for life will be different?

I think life mostly looks the same throughout the universe, but endless variations like here on Earth. We can`t send radio-signals to reach them, because it just disolves after some light-years. We can`t travel faster then the speed of light ether, so we get bored with finding life long before it.

In our current age of the universe, let`s say again that only a galaxy shaped like the Milky-way can hold life. Before the galaxy that held life was different, and will be different from that and current in the future. They have found a galaxy shaped like the Milky-way. It`s 11 billion light-years away:

Is this the only place aliens can be then?

Chances are lots of galaxies out there can sustain life.

Are you so sure, really? They don`t seem to have any life, maybe it`s the wrong galaxy? Why wouldn`t life start there if it was perfect for it?

What methods have been used to find life on others planets?

I just mean if you have tempered water, atmosphere that protects against radiation, a moon that blocks meterories, a heat-source inside the planet, a sun in the right distance etc. that plants will starts to emerge, and after that more advanced life that uses the plants for protein. Maybe you need the right galaxy?

Which extra-solar planets have detected:

an atmosphere?
a moon?
an internal heat source?
are at the "right distance"?
have plants?

and what galaxy are they in?

How would we assess whether they have life in or not? The Universe could be teeming with life; but it’s so far away in time and space that we might never know. Whole civilisations could have rose and fell without every having any contact with each other and we are destined to go a similar way.

So I ask you: what is your metric for detecting life?

Here's a 3d perspective that destroyed the groupings we call constellations here on earth from our perspective: Constellations in 3D

Mostly science fiction passes for science fact in cosmology... especially these days with the exoplanet craze. There is only so much we can observe from these great distances (including the inability to accurately measure the distances). It is presupposed (or agreed on by people who have no clue) the temperature and make up of a star is according to their agreed upon supposition / bias. Red stars (for example) are such and such a temperature and so and so old...

We cannot even confirm that our galaxy is a spiral type or where we are in reference to any center or if its center is a black hole or a white hole. They just agree to agree with each other on the traditional suppositions and treat people like imbeciles if they question their dogmas.

Exoplanets and cosmology have nothing to do with each other.

All of the exoplanets are around nearby stars. All within range of the parallax measurements with the Gaia satellite. Their distances are well known.

Those determinations are made by the people who do have a clue (astronomers).

The arms have been mapped. They were mapped in molecular line emission over 50 years ago. Modern distance measurements of stars show the spiral pattern as well. (That the Galaxy has a disk shape is fairly easy to establish (about 100 years ago), but the presence of the spiral structure required the mapping of interstellar gasses with radio telescopes.

It's 8.5 kpc away and we've known that for decades.

It is a black hole (Sgr A*). The accretion disk around it was imaged a few years ago.

They have the evidence. The scoffers don't. Are you any better positioned in your "criticism"?

You’re thinking much too big. Galaxies are gigantic and can have many varying conditions within them. For example our solar system we know supports life but only on this one planet out of 8. That’s just one single star out of the hundreds of millions or billions of stars within our one galaxy. Our galaxy as a whole could be teeming with life all over -some could even be as sophisticated and intelligent as we are, but the distances along with how fragile we know life to be makes it likely impossible we’ll ever get to meet our celestial neighbors. I believe they’re out there but as equally isolated from us as we are from them.

Stop being silly. White holes have never been detected.
