holograms.. I reckon so yes! Technology is already around like the hololens that lets us see holograms through special glasses. If you are a gaming fan I bet you might have already seen this: https://www.youtube.com/watch?v=xgakdcEzVwg . As for holograms we can all see.. it is not around yet but I think it is definitely not outside the realms of possibility. 🙂
As Connor says, hologram technology is advancing pretty quickly, though we’re not at proper 3D Star Trek style holograms just yet. I’d say we’ll have them eventually though.
I’m not sure we’ll have holograms that can go anywhere though, not for a long time anyway. Current hologram technology needs a lot of lenses and projectors, and that’s all bulky equipment. To take a hologram anywhere, we’d need to first figure out equipment to make it work, but then figure out how to miniaturise the equipment so it’s portable.
So it’s a long way off, but do-able! Maybe you should try doing it!
