Wow stunning. Our galaxy was the last one standing and continued to suck in others and merge, as it is now doing with the satellites and next in line Big sister Andromeda! That'll be another long battle of Titans. Love this simulation well done 😍

The final collision between the two progenitors of the Milky Way would have happened somewhere around 10 billion years ago. We currently have evidence to suggest a large galaxy collided with the young Milky Way at that time. Edit: As an update to my comment, more recent simulations suggest the Milky Way has had a much more turbulent past than we originally expected. It may have been a part of a major collision as recently as 7 billion years ago. As this simulation is over 8 years old, it can't account for this new information.

What point in the video is supposed to be present time? Takes 225-250 million years for the sun to orbit the center of the galaxy according to google. How many civilizations were born and destroyed in the course of this video?

En prenant en compte la date estimée de la formation des premières galaxies comme repère fixe dans l'échelle du temps, partez du principe que chaque seconde qui s'écoule de cette vidéo représente environ 50 millions d'années. C'est une estimation, sinon juste, mais au moins proportionnelle à l'âge estimé de l'univers.

@@everettmusicdojo I think present time is somewhere around 0:54 as the milky way and andromeda are approaching eachother for the first time. That would make it roughly 14 billion years per minute. Round it to 250 million years per second which is about one galactic year per second. The other possibility is that the end state galaxy is supposed to represent the milky way. I guess that makes more sense based on what the title implies. In that case present would be somewhere in the end of the video. Maybe the very end.

@@batman3698 Andromeda is much much larger than the milky way, i believe this is a simulation of the milky ways past, and the present is more likely the end of the video even if andromeda or other satellite galaxies aren't present

gwynethgirl is correct, proto-galaxies were much smaller and rotated thus changed much faster.

Also, time is relative so my theory is that when they say the universe is 14B years old, that’s using today’s time scale. The Big Bang was instantaneous followed by rapid expansion at much higher than the speed of light... OR time was just much slower then so what seems like seconds at today’s time scale could have felt like millennia if you lived at the time. My idea is that if you correct for the time dilation, the universe is infinite - because the closer you get to the Big Bang the more time dilates. That’s pretty much the definition of a singularity.

@@JM-nm3bg The passage of time has never changed speed. Time dialation is purely subjective.

Okay, but time dilation is a fact when talking about black holes. It’s said that you never actually fall into the singularity because spacetime dilates to infinity at the event horizon, in effect all the data is shredded and stored at the event horizon. I think the Big Bang was just the reverse of this.

@@JM-nm3bg Ahhh, there's the difference. To the observer falling into the event horizon, they would be falling into the black hole for eternity due to time dilation. To an outside observer, you would see them fall in. Again, it's a subjective phenomena.

I believe you dropped a decimal point, more like 106.647.000 years? the video is 136 seconds, divided into 14.500.000.000

Andromeda is twice as big as the Milky Way and milkdromeda is probably gonna be an elliptical galaxy So no it wasn’t

Hubble's expansion (first galaxies appear hundred of millions of years after inflation).

Hubble's Law. If it wasn't for the expansion of space, over the span of several hundred billion years, superclusters including ours would eventually converge into single gigantic clusters and then eventually a hypermassive single galaxy. Over even longer periods of time, superclusters themselves would begin to merge with each other, and so on until most of the mass of the observable universe is contained within a single ultramassive elliptical galaxy. Somewhat unfortunately, this gigantic mega smashup won't occur and most clusters' evolutions will end once all galaxies have been either merged into a single galaxy or ejected, and they will slowly fade away over the next quintillion years. If it wasn't for that, the gravitational evolution of the universe would probably continue for several quadrillion years from present instead of the next 500 billion at most.

It can't, angular momentum keeps all of the stars in a constant orbit, but if angular momentum was = 0, the would all fall into the center black hole

wow this is so amazing

this is a simulation projected by an supercomputer

No.

Description

Yes, all of these proto-galaxies presumably have a supermassive black hole. Galaxies stay together and form their shapes through the collective gravity of all the objects in the system forming a centre of mass at the centre of the galaxy. The supermassive black hole actually has nothing to do with keeping the galaxy together.

No.

? It doesn't appear out of nowhere, it's basic physics. The combination of inertia and gravity creates a rotation. You have to understand that these simulations run on nothing more than simple physical laws, saying that the spin comes out of nowhere is like saying clouds come out of nowhere.

arent you guys kids that does not know how to Learn time stamps?

Okay? That doesn't mean anything, you can't be sure of most things, the only thing you can truly know 100% is the fact that you exist, but anything external to yourself you cannot know for sure, you can only know what's probably true based off of evidence and reason, and the evidence shows with high probability that this is how galaxies - including the Milky Way - formed.

@@Evolcun Yep, and that proves my point. :) Sorry to you, I don't want to be pedantic. Thing is - what we think NOW to be a high probability may in part be down the drain soon. If I realize that the fact of spacetime coming into existence actually speaks against itself, I then do take most of the things mentioned with such bravoure with more than a pinch of salt. Listening to: Simple Minds - Once upon a time.

jaime dungca No it’s not the Milky Way And Andromeda.Its a Major Merger that soon made our Galaxy

It depends on your definition of 'collision'. If you mean all interactions with anything that can be considered a galaxy, then yes, the number of other galaxies we've interacted with is probably in the hundreds. The current number of galaxies in the Local Group is c. 47, so in the distant past that number was most likely in the hundreds. If you mean collisions involving galaxies that significantly disturbed us and changed the Milky Way forever, then there have been around 3 or 4 of those after the primordial Milky Way can be considered to have started existing, ~10 billion years ago. The most recent probably wasn't later than 5 billion years ago. M31 on the other hand has had major interactions and disturbances as little as a few hundred million years ago, and only formed around 4 billion years ago through the collision of two smaller galaxies.

Yeah really, these simulations aren't coded to do specific things, they just plug in "particles" and the mathematics for simple laws of physics, and this is the outcome.

It’s just the formation

If that happened..our solar system would vanished and planets would be orbiting in no where

@@barnyard835 Galaxy collisions have extremely remote chances of ever affecting individual star systems. It happens so slowly and the stars are so far apart that they virtually never interact.
