The 4D Universe [720p]

[NOTE: original soundtrack and voiceover in Italian has been replaced by this audio track; all text copy has been translated -- roughly! -- from Italian into English]

Flying through a evolving cosmic structure, starting at early times (the so called dark ages), where the material in the universe is in a cold and neutral state. First objects collapse and form the first proto galaxies embedded in a heated atmosphere, hosting the first stars and QSOs. The energetic light from those stars/QSOs heat and ionize the material in the universes (note that this simulation takes this not self consistently into account, but uses a uniform, time dependent background radiation field), revealing the fine, filamentary structures formed so far. Now, lager and larger structures form within a long and violent process of merging of smaller structures leading to the largest objects observed in the present universe, the so called galaxy clusters, still connected to each other by filamentary structures. At the end, the movie zooms down to a spiral galaxy, similar to what we expect the Milky Way looks like, for a final fly-by. In this case the galaxy is artificial constructed from an astronomical image, as it is still impossible to obtain such detailed and realistic galaxies directly within cosmological simulations. This movie is also shown in the Virtual Reality facility of the new Turin Planetarium.

awesome!

@banana1337kivi - this is probably my absolute favorite visualization on my channel. I love watching it on my 55" living room TV -- real easy to get sucked in!

[kikadin]

I love the background music, what is the title?

[djxatlanta]

@kikadin - I wish I could tell you -- it's one of the stock soundtracks from YouTube. The original video had a voiceover in Italian (it was produced for a planetarium show), so I found a track on YouTube to superimpose over it... unfortunately, YouTube doesn't tell me what it was. :-(

[MrFreeOliveira]

Great work ! Tonite I'll visit this place in my dreams ! \o/

[djxatlanta]

@MrFreeOliveira - I didn't create the animation... the source credit is at the bottom of the video description. =) Hope you had pleasant dreams! =)

truly amazing.

beautiful!!

[antaressuper1966]

they keep saying the andromeda is comming torwards us and someday it will clash with our galaxy, well then how can they say that all the galaxies are moving away from each other

4D ??? WTH... im still seeing in 2D LOL... ok... lets say that its "timetraveling" so even if i add the 4th dimesion (the time) to my "calculations" im still watching it in 3D ... LOLZ... but it was at least nice video :)

I saw Fred Flintstone wavin' at me from the Dino Burger restaurant at 3:37

is this copyright protected?? Because I wanted to use it in my short film for my IB film project.

its so beautiful, people here on earth are all so caught up in other things to even look up and wonder, what is really out there?

[kannabiz420]

@HyperShadic0 whatever, the point is: I really like pepperoni pizza.

[HyperShadic0]

@kannabiz420 OF COURSE IT'S FAKE! It's an animation!
