Another simulated camera pull-away from out plantet outwards

This is a good one.

Question: Why can we only observe two "cones" facing opposite directions with voids in-between?


Video: Simulation Renders Entire Known Universe

Everyone loves a good road movie, whether it's Hope and Crosby or Fonda and Hopper. But the scope of those films pales in comparison to the ground covered by the Hayden Planetarium's new video, The Known Universe. The video starts in Tibet and zooms out through time and space until it shows well, the entire known universe.

The video, created for the new Rubin Art Museum exhibit Visions of the Cosmos: From the Milky Ocean to an Evolving Universe, uses over a decade of data collected by researchers at the planetarium. Called the Digital Universe Atlas, the data encompasses the precise location of every object ever observed in the sky. From quasars to pulsars to black holes to nebulas, it's all there.

The observable universe spans 13.7 billion light years, with the background radiation aftershock of the Big Bang as the oldest, and farthest, signal. At that end of the universe lies the oldest material in creation, which, thanks to billions of years of expansion, has accelerated to almost the speed of light. That layer forms an event horizon past which not even light can travel, ringing our universe in what is essentially an inside out black hole.

But enough of my yammering! Check out the video yourself, but make sure to budget some extra time for sitting in slack-jawed awe.

That's wild. Crazy to sometimes think that we are the most important person in the entire universe.

Great video, thanks for sharing.

I'm not sure we can only observe the two cones, I think it is that we just haven't had time with the available technology to map the voided areas.

Someone correct me if I got that wrong.

Maybe could have to do with the light that we have available to see?

that was amazing.

We sit in the disk of the Milky Way, and can see up and down to objects outside our galaxy, but the disk itself blocks our view in the oher directions.

Ahhhhhhh.....

Makes sense. ... Hmmmm.... But, aren't we on the edge of our galaxy so to speak? Shouldn't one cone be bigger [clearer?] than the other?


EDIT: Let me rephrase: Wouldn't one of the extra-galaxy observational voids be smaller than the other? In other words, the void facing the the thickness of the central galaxy be larger then the void looking outwards from our spiral?

Makes me realize how small I am.

+1

Cool video

Im also going to add, with how big we know the known Universe to be, doesnt there just have to be other life out there? Im no scientist or conspiracy theory nut job, but it really makes you think. With all that space, are we really the only planet with life on it?

there is no possible way. they would have texted us by now from their 9 billion G network.

How small we ALL are. We as human are no more significant than the tiniest insects we crush. To think otherwise is the epitome of arrogant.

But see thats what makes things interesting, what makes something significant? By your definition its physical size.

A very famous Jedi Knight once said: "Sive matters not."

Just because the human race is physically small compared to the rest of the Universe, does that make our existance insignificant? Id argue that our ability of free will, rational thought, and hunger for knowledge does indeed make us, as a whole, very significant. To our knowledge, nothing else in the Universe exists on the same level as we do.

Without the human conciousness, there is no Universe, because it is just that of us which percieves what is around us.

It's not just that, but the acknowledging the vast area that we have not even identified yet. To think we are the only game in town in terms of intelligent, advanced species is incomprehensible to me.

I agree with you there.

I really wish I knew more about Physics and Psychology than I actually do, it could lead to a very interesting life of study.
