over the digital hand in front of you so so i guess if you just have your dog kiss you while you experience that magical smooch in vr it's basically the same right another trick used in vr is accelerators that detect body motion which can then be integrated into your vr experience making it feel more real and immersive and with a thing called redirected walking vr can manipulate your brain into feeling like you're walking in a long straight line when in reality you're just going in circles all the better for long walks on the beach with your crush but vr can also avoid physical movement altogether by tricking your internal perception of self-motion also known as vection adding multiple visual auditory tactile and environmental cues can enhance vection so vr can also make you think you're slow dancing in the moonlight when you're really just sitting on the couch so are advanced vr visors are back door into the matrix not really for one engineers aren't yet able to create photorealistic images in real time so your digital reality is going to look more like second life than first life in fact researchers estimate that creating simultaneous life-like renderings would require NUMBER_TOKEN petaflops of rendering power which is way beyond what we're capable of for perspective one petaflop is NUMBER_TOKEN times more powerful than the human brain and then there is the pesky mismatch between our input systems that means that while the vr visor can handle visual inputs our brains still need to mix those visual inputs with things like touch and smell which won't all match up the result you'll feel nauseated with continuous use which isn't an inaccurate experience of adolescence so while redoing your awkward team years in the matrix isn't possible right now it's absolutely a possibility in the near future according to frank steineke a computer scientist from the university of hamburg we can easily assume that within the next NUMBER_TOKEN to NUMBER_TOKEN years or so we will not be able to distinguish visually computer computer-generated content from real-world content anymore and if you've survived the NUMBER_TOKEN years since a horrible prom night mishap what's NUMBER_TOKEN more years to digitally redeem yourself and there's good reason to be hopeful according to astronomer david kipping there is already a NUMBER_TOKEN NUMBER_TOKEN chance that we're living in a simulation and the day that we create a simulated reality with conscious beings inside it those odds jump from NUMBER_TOKEN NUMBER_TOKEN to oh oh we're almost certainly not real so who knows maybe we already live in a simulated reality maybe we're all just gross little babies in jars on some dystopian future planet using our natural energy to fuel a monstrous system of autonomous machines and any successful vr system we develop will just be another layer of deception created to keep us further removed from the monstrous truth of our own existence but as long as we get french kissed by a dog we'll probably be okay that's all for this one but thank you so much for watching and come back soon for another science is hard later
