I would like to see a simulation of what happens when two black holes that are rotating in opposite directions collide or merge. if one is going clockwise and the other anti clockwise. and when they coalesce they go in an anti clockwise direction. would frame dragging help them sort it out? with latest data stating that a black hole can rotate up to the speed of light, or a good percentage of it at least. how do they dispense of the high angular momentum? does the resulting object have less rotation or is it a energy is conserved thing?
Both energy and angular momentum are conserved. The total angular momentum won't be that much though. Since the rotation directions are opposite angular momentum of the two bodies cancel.

Can you do an Oort cloud sim please. there are so many artist images of Oort cloud of a very similar geometry, then a galaxy sim can give us the same geometry as the art images? A simulation since pre disk solar system including cross section views. The Oort cloud images used a physical equation base, so we can use them as a 3D gravity cloud visual?
The dark matter distribution can be modelled based on observations from a number of galactic sources. Dark matter should also follow the same gravitational laws and so modelling the likely distribution of it at the start of the process will yield simulation results that are compatible with our observations of galactic collisions.
im so confused... are we seeing this happen with the 2 same galaxies or are there just abunch of other galaxies that are coinsidently in the same posistion?
in the photographs, we can see a bunch of actual galaxies (0:16 (galaxy pair), 0:33, 0:44, 1:00, 1:15) observed via telescopes at different locations in the sky; spatial configurations of these observed galaxies happen to closely match spatial configurations appearing in a computer simulation of a collision between two elliptical galaxies; so, though galaxies in the photographs are different galaxies spotted at different places in the universe, they have one important thing in common - type of their history; all of them are results of collisions of elliptic galaxy pairs; those collisions started in some less (0:33, 0:44) or more (1:00, 1:15) distant past or are "just about" to start (0:16); this is why shapes of these galaxies are different as we see them today - they are snapshots from different stages of "post-collision" galaxy evolution; snapshots being hundreds of millions or even billions years apart; so, no, we have absolutely no chance of observing such evolution for a single galaxy pair; it just proceeds waaaay too slowly (to put it mildly...); ;-)
маленький вопросик ) эти снимки 0:160:360:441:15 реальны и на их основе построена симуляция? Или они просто раскрашены как это делают на снимках галактик?
they run a simulation starting from an initial configuration that has been observed in nature (0:16); the simulation then evolves into a series of other configurations; some of these configurations have also been observed in nature (0:33, 0:44, 1:00, 1:15), although visible at different angles from Earth; this is why the simulation view is being rotated in the film - the simulation view needs to be rotated to match the real life photographs;
They might as well be the size of a atom in the big picture.Most likely the pretty much everything in the 2 galaxies will smash up and reform a new galaxy.Meaning the stars and planets are fucked.
Distance between stars are so great that they wouldn't collide. But peripherical stars could be ejected from the parent galaxy and orbit it farther away.
The distances between the stars are so great that usually not even one star collides with another. This is hard to believe when looking at the video, but it's true.
et on nous explique que l'Univers est en expansion parce que les galaxies s'éloignent les unes des autres... ha ! au fait à quelle vitesse va le présent ?
A plus grande échelle, les galaxies s'éloignent en effet les unes des autres. Cependant, localement, l'attration gravitationnelle entre elles peut les faire entrer en collsion. Par exemple, notre galaxie la voie lactée entrera un jour en collision avec andromède: fr.wikipedia.org/wiki/Collision_entre_la_galaxie_d%27Andromède_et_la_Voie_lactée
Ashe Dezinklsky I read that our system would likely stay intact. The distances between the stars are so huge, that most of them will pass each other by. And the gamma rays from the two black holes merging, would quite likely miss our system too.
Our galaxy is relatively massive and being orbited by 13 other small galaxies. 4 are actually being gravitated into our own galaxy, so in some ways other galaxies are actually "colliding" with ours as we speak.
Amazing get it baffles me how we are now traveling in space and seeing back in time somehow learning so much about space and time and seeing all these wonders glorious sites of our universe and our galaxies and yet man can't even go to the bottom of the ocean in recover a lot of the old lost sunken ships treasure ships with treasures of gold and the creatures the older in the deep the dark deep ocean as I'm just baffled we can't make a machinery and spend more time in the bottom of the ocean finding other mysteries right here in our own planet????🤔
I have one basic question. If through hubble, we can see the beginning of the universe 13.7 b years ago, and near the time of the big bang, from earth, can we see ourselves there 13.7 b years ago? We were there , 13.7 b years ago. Weren't we? If our telescope was much more stronger, could we see our own galaxy there?
We're seeing how the Universe was 13.7 b years ago. Back then, there were no planets or stars or galaxies. Everything was in the form of either atoms or photons (light). So when we look that far away -- that far back in time -- we only see the light from that time. The light from that time is known as the Cosmic Microwave Background (CMB), because it now appears to us as light in the microwave part of the spectrum.
if you could teleport 50 light-years away from the Earth with a big enough telescope and looked at the earth, I think you should be able to view the earth as it was 50 years ago.
Great question. The answer is "no". For this to happen, our own galaxy would need to have reached where it is now faster than its own light, which is impossible. What we're seeing at those distances is other parts of the universe that were far away even back then, and are much more mindblowingly farther away now. Even back then, the universe was over 370,000 years old, because before that time, the universe was opaque, so light emitted before that time was just reabsorbed.
The Cosmic Background Radiation Ambient Noise map shows us the density of galaxies when we observe the universe from the earth. There more galaxies in red spots and less in the dark areas. the noise is not the left over of big bang, but the collective noise of galaxies. see Hubble's UItra Deep Field. When James Webb telescope is ready, we can find a black spot in Hubble's UItra Deep Field to have long long exposure picture, what we will have is Webb's UItra Deep Field, repeating Hubble's UItra Deep Field patent. The big bang is very suspicious, to me, the redshift is caused dark matter and dark energy, not by galaxies moving away from each other. If the universe were expanding faster and faster, galaxies would move away from each other, at one point, galaxies would stop collations. But the collations happened, are happening, and will happen for ever. The arms of a galaxy indicate how many collations that galaxy has gone through. No arm means original galaxy. The arms and sub-arms numbers (N-1) tell us how many collations that galaxy experienced. Two arms, one collation. Two main arms, one of them with a minor sub arm, three collations; formed by one galaxy and one galaxy had prior minor collation. The galaxy can't grow infinitely, when the mass go beyond certain amount, the core will explode. The universe is isotropic. To the people live at the end of James Webb telescope can ever reach, think that we are as old as we thought they are.
The simulation must have been made to match the observations, as I cant believe that at certain points the simulation happened to exactly match an actual observation.
Not per se, there are plenty of observed colliding galaxies. For any begin condition you can find most likely a couple of colliding galaxies that fit it if you turn everything a bit.
The simulation was done in 1995, but the observations it matches were not released until 2008. There were 59 possible matches in that press release and I was able to match 5 of them by changing the time in the simulation and the camera viewing angle. I wrote some special code to help find those times and positions.
There are about a trillion galaxies in the visible universe. So, yes, it's very much possible to find examples of galaxies that look like pretty much any realistic simulation just by luck.
@@FrankSummers One thing that would be fascinating to see in modern space simulators and space engines would be what it would look like to be inside a colliding galaxy. To be on an exoplanet at night, and look up to see multiple swirling arms arcing across the sky in odd ways, with bright nebula being formed.

Well the thing is....if you would be able to survive till our Galaxy collides with Andromeda, you actual would not feel a thing. Life would be unharmed and so would be our sun system. Because those dimensions are so damn big, that it would not affect our system. The only change would be on our night sky.

You're seeing one simulation, accompanied by several real galaxies that resemble different stages of the simulation.

Short answer: nothing. Almost none of the solar systems in such galaxies would notice anything except the galaxy would look different in their sky.

You would think with space being mostly space this would never happen. I guess we need a yield sign along with the speed of light sign.
Gravity pulls galaxies toward each other, so they collide much more often than they would if they were distributed randomly.
