  • Space is defined as 100 km high.

    For the first 10 km or so, with current technology, it’s possible to imagine a very light structure in part composed of big impermeable fabric envelope filled with hydrogen that would have a net weight of about zero because of buoyancy in air.
    The difficult part is the next 90 kilometers high for which i believe we wouldn’t be able to build anything that could sustain its own weight.

    On the other hand, if cost and energy was not an issue, with current technology, we could build enormous number of big tanks into which we would pump all the atmosphere, so the height of space would come down to sea level.

    … of course we would then have also to put oceans and all bodies of water in tanks, otherwise they would boil out into space.











  • After DeepSeek_R1 (and Alibaba’s thignie surpassing o4) we have this (OmniHuman-1). All this shows, once again, that Chinese are now ahead of the game in a.i. Searchers who want to keep up have to, at least, study what the Chinese have accomplished.

    (…) OmniHuman-1 is [way] above previous deepfake techniques, (…) While ByteDance hasn’t released the system, the AI community tends [to rapidly] reverse-engineer models like these.
