Powers of Ten on Starry Night

[biblia2016]

It's very nice to have a quick view of the inimaginable greatness of the space around us and the multitude of galaxies and stars and possible habitable if not populated planets out there. "In my Father's house are many rooms" (John 14:2).

btw, the sound of the pulsar was produced by the speakers of the space ship vibrating by the electromagnetic waves produced by the pulsar.

Original is much better than knockoff.

I have the Starry Night program and I can't get mind to do this. Is this some kind of extra download that enables all the galaxies out to 10^27 metres?

[Konoton01]

Consider that each galaxy has millions of stars and planets in them.

Maybe Earth was a 1:1,000,000,000 shot but I'll eat my hat is there isn't life out there.

[kdum8]

me too. Probability alone says life must be common on a universal scale. It would be extremely strange indeed if there were not. Whether we will ever find it is another matter altogether though.

[MrIcicle]

with a radio telescope and an amplifier you can :-)

[alamoghost]

Not if you are deaf :)

For a science video, you' d think they'd know at 10^19m, you wouldn't be able to hear the roar of the pulsar through a vacuum.

(Yes, I'm rather picky.)

[shongage]

Sounds still happen in space. You just wouldnt be able to hear them through the vacuum. I like to think you're just hearing the sounds that are still happening whenever im watching star wars or stuff like this

[kdum8]

No they don't. Sound waves require a medium to travel through. No medium, no sound. Simple as that. Space being essentially a vacuum provides no medium for waves to propagate through. It isn't just that you can't somehow "hear" the sounds that are in space... they really aren't any sounds in space!

[shongage]

what i meant was yeah, sounds dont travel through the vacuum.. but the sounds are happening within the things that are making the sounds. Like, if you bang on a meteor, the sound would happen within the meteor's particles, it just wouldnt travel outside of it

[kdum8]

Ahh. Well that is vibrational energy within the structure of the objects. It isn't sound in the traditional sense. But yes, if your ear were actually in contact with the object you could hear something. Still personally I am not putting my ear in contact with any stars anytime soon!

[kdum8]

And picky you should be! There are no sounds in space...

[gJonii]

@JoeDonFan "Hear" is probably just a bad way to phrase it, I guess they mean it sends electromagnetic radiation of a really low frequency that we could interpret as "sound" of these large formations(affected heavily by macro-movement of these bodies, say). Naturally, taken to mean sound waves, the claim is absurd.

Though this is just a guess, I'm really no astrophysics expert.

[JoeDonFan]

@gJonii that is a fair assessment.

[piceras]

awesome!! what about leading the viewer from 10^1 meters to get full effect?
