The Scale of the Universe
- koenbok 15y agoReminds me of IBMs Powers of Ten video: http://www.youtube.com/watch?v=0fKBhvDjuy0 http://www.youtube.com/watch?v=0fKBhvDjuy0
- aoe 15y agoGreat visualization. Is there really no object in the 10^-24 - 10^-34 range?
- oscilloscope 15y agoLooks like the Sloan Great Wall is the biggest: http://en.wikipedia.org/wiki/Sloan_Great_Wall http://en.wikipedia.org/wiki/Sloan_Great_Wall "it is the largest known structure in the universe"
- mootothemax 15y agoPlease can you link to the original (http://htwins.net/scale2/ http://htwins.net/scale2/) and not the blogspam version? :-)
- joelrunyon 15y agoOops - sorry, this is where I found it. I can't change the url after the story's been submitted - sorry.
- heed 15y agoWhy did it stop at a planck length? I thought space was continuous.
- Tuna-Fish 15y agoThat is actually an unknown. There are many theories that postulate discrete space, but there has been a dearth of reliable experimental tests for it.
- zbyszek 15y agoIt's a hard hypothesis to prove either way. One finds that quantum effects dominate the physics at smaller length scales. In quantum theory, the smaller a thing is (its Compton wavelength) the higher its mass or energy. At the Planck scale the density becomes large enough for a black hole to form. So we can get quantum fluctuations creating virtual black holes, which means that the description of spacetime as a continuous thing is invalid.
