That is not necessarily true. In our galaxy yes, total obliteration, but in other galaxies including them that we are not aware of, life could continue.

Life travels through space, at least the building blocks do, and it is possible that life on Earth came from space, perhaps traveling on icy asteroids. If you’re interested, read about panspermia.

I have ready authors like MIchio Kaku and Brian Cox. As you say it is possible. At present our knowledge is insufficient to understand the universe

I have read quite a bit on this and everything is possible. We understand almost nothing about the universe and life.

We need some mystery in our lives. If everything was laid out and clear, what would life be about?

The only thing I honestly do not understand is how people can jump on theories, stories, and fairy tales as truth, and the only truth.

The collision between the Milky Way and Andromeda?

What's interesting to me is that when the galaxies collide, the likelihood of any two stars actually colliding is slim to none. They're all too far apart. We'll end up with one big galaxy, but no major drama. By that time, Planet Earth will be ancient history, in any event.

Yes.

I was thinking about this, just the other day.

In fact, we are travelling through space, just from the perspective our own galaxy, or relative to the center BLACK HOLE of our galaxy, at a speed of about ....well...we can ask this question of Gemini:

What is the speed of our solar system, tangential to the black hole of the Milky Way.....

The answer is, OF COURSE:

Gemini Overview

The solar system travels at a tangential (orbital) speed of approximately 230 km/s....around the supermassive black hole at the center of the Milky Way, Sagittarius A*. [1]

Breakdown of the Speed

• Proportion of light speed: 1/1300th the speed of light (in a vacuum of course, FOLKS....)

Key Orbital Details

• Distance to the Black Hole: The solar system is located approximately 26,000 light-years away from the center of the galaxy.

• Galactic Year: At this speed, it takes our solar system roughly 225 to 250 million years to complete a single, massive orbit around the Milky Way's center.

INTERESTING FACTOID: My brain is about one meter from my black hole.

I love astronomy and cosmology.....

This is false, I am fairly sure.

The gravitational forces will be immense.

I'm pretty sure I'm right. You should look it up sometime. It surprised me when I first read that, but that's what they say. Of course, Planet Earth will no longer exist when all this comes to pass.

Exactly. The people with the most knowledge are not uick to say one thing or another will happen. The closest they come to that is that if a situation progresses in the way it is currently moving then a possibility exits but not definitely.

The people I know who have real knowledge admit what they do not know, and are rarely completely sure about anything, especially in open and honest discussions. We can still have strong discussions about matters where there are no real proofs, only stronger or weaker arguments.

It is important to think abstractly, dig deeper, push limits, and maybe reach a common understanding or change our minds. I truly believe that is the only way opinions change, not only the opinions of others, but our own as well. It comes with education, curiosity, experience, good people around you, and a willingness to change your mind when the facts or stronger evidence point somewhere else.

It would seem reasonable that we move to another dimension or world as the science state "matter can neither be created or destroyed". To be sure I guess we will have to wait and see. For me I think there is a definite possibility that the theory is at least partially correct.

NO.

You are NOT right.

The radiation levels will go through the roof.

Two black holes coliding would destroy any atmosphere on any planet.

And, you know, I am nearly always right.

So, this does not surprise me....a bit.....

AI Overview

During a galaxy merger, planets rarely suffer direct physical collisions because stars are separated by immense, empty space. However, radiation levels skyrocket due to bursts of new star formation and active black hole feeding. These factors trigger intense gravitational chaos that can strip, sterilize, or completely eject solar systems. [1, 2, 3, 4]

Radiation Level Spikes

• Starbursts: Colliding gas and dust clouds trigger massive bursts of star formation. These short-lived, hyper-massive stars die quickly in violent supernovae, flooding space with lethal X-rays and gamma-ray bursts. [1, 2, 3]

• Active Galactic Nuclei (AGN): Mergers funnel interstellar gas into the supermassive black holes at the galactic centers. As this matter accelerates and heats up, it radiates intense ultraviolet and X-ray energy, sometimes forming brilliant quasars that can strip away the molecular gas of companion galaxies. [1, 2, 3, 4]

Potential Effects on Planets

• Atmospheric Stripping: High-energy cosmic rays and intense radiation from nearby supernovae can erode a planet's magnetosphere and atmosphere, exposing the surface to deadly stellar and cosmic radiation. [1, 2]

• Orbital Disruption: As the galaxies merge, the gravitational potential of the entire region changes, altering the stable orbits of stars and their solar systems. Planets may be gravitationally perturbed or entirely ejected into intergalactic space, plunging into perpetual freezing darkness. [1, 2, 3, 5]

• Collisions with Stray Matter: The gravitational turmoil can dislodge Oort cloud equivalents, causing a dramatic spike in asteroid and comet bombardments on planetary surfaces. [1]

You should.....LOOK IT UP AGAIN.....

And then get back to me.

Thank you.

Apple and oranges. Did you miss the part of my post where I said planets will almost never collide? Your own post says as much. And that's all I said. So make up all the nonsense you want, I was right.

FALSE

FALSE

Totally, and indisputably....FALSE.

As I already stated early on, this even will spell the end for all life...THE END....get it?

Also, I earlier mentioned immense gravitational forces which sill cause HUGE DRAMA...Now do you get it?

There will also be GAMMA RAYS, aplenty.

You stated: We will end up with one big galaxy, but NO MAJOR DRAMA....

What are you even talking about?

So: YES, despite what YOU might think....there WILL be MAJOR DRAMA....

Take a course in Cosmology, why don't you.

The forces involved in collision or merger of galaxies have been known for many decades...at least since I was in school.

Try just one year of a decent Astronomy course at a decent university, and welcome to study the chemistry of the Sun, and many other interesting topics.

You really might learn something.

No. NOT all life (in the universe) (will cease).

The headline of this glorious Topic is: This is the end.

I showed a simulation of the merging of the two galaxies in question in the Original Post.

I stated that: This would be the end (FOR US)...... as a qualifier.

YES: iF and WHEN Andromeda and the Milky Way galaxies collide, and as I previously stated clearly, the resultant GRAVITATIONAL FORCES will destroy all life. Intense GAMMA RAYS and other wonderful radiation will STERILIZE alll life in BOTH galaxies.

Obviously, other galaxies not involved in this collision will go on as if nothing had happened...OBVIOUSLY.....

Please NOTE: I also mentioned Musk, and people like Musk, who think they can preserve "intelligence" by escaping from Earth. Well, it might be possible to travel to a star within our own galaxy...BUT...intergalactic travel is completely impossible...THIS MEANS that all intelligence in our galaxy will cease, unless you include the "intelligence of galaxies and the intelligence of the universe", which is something else entirely.

If we cannot travel to another distant galaxy, which we cannot, then the Headline of the Topic remains....CORRECT.

I should have thought this was obvious from the Original Post, but apparently not so obvous to some.

Would you not agree?

You might want to contact Elon Musk and tell him his Grok product is giving out misinformation. LOL

No, the merger of the Milky Way and Andromeda (M31) will not cause chaos that destroys all life across both galaxies. It’s a slow, mostly “gentle” gravitational dance on cosmic scales, not a violent smash-up like two cars colliding.

Why the merger is not destructive to life

•  Vast distances between stars: Galaxies are mostly empty space. The average distance between stars in the Milky Way is enormous (several light-years). Even as the galaxies pass through each other, direct star-star collisions are extremely rare—astronomers estimate the probability for our Sun is near zero.

•  Timeline: The process begins in roughly 4–5 billion years and takes hundreds of millions to a billion+ years to fully settle into a single larger galaxy (often called “Milkomeda”). It’s gradual, not sudden.

•  Main effects:

•  Gravitational tides will distort spiral arms, fling some stars into new orbits, and possibly create tidal tails or bridges.

•  Gas and dust clouds will collide more readily, triggering bursts of new star formation (and associated supernovae in those regions).

•  The central supermassive black holes will eventually merge, releasing gravitational waves—but this happens at the core and poses no threat to distant stars/planets.

•  For solar systems and planets: Most stars and their planets will simply continue orbiting in the new combined gravitational potential with minor perturbations. Life (if it still exists) would face far bigger existential threats from stellar evolution long before or during this era.

Context for Earth specifically

By the time the galaxies start interacting significantly (~4–5 billion years from now), our Sun will already be evolving into a red giant, making Earth uninhabitable due to increasing luminosity and eventual engulfment—independent of the merger. Any remaining life elsewhere in the galaxies would mostly be unaffected by the galactic-scale events.

Simulations (from Hubble, Gaia data, and models by NASA/ESA) show a beautiful, structured merger rather than apocalyptic destruction. The night sky on Earth (or equivalent planets) would gradually change as Andromeda grows larger and brighter, eventually filling the sky with new stars and structures.

In short: Galactic mergers are common in the universe and are creative events (new stars, morphological changes) rather than sterilizing ones. Life, where it exists and can persist, would have a front-row seat to a spectacular cosmic light show.
