Atoms, molecules, electrons, photons, protons etc.
If a surface looks "shiny" to you, that's because it reflects all
or most of the visible light that hits it. That doesn't always mean
that the same surface reflects other, non-visible wavelengths of
light. Infrared radiation may also reflect off of it, and probably
does. But you can't be sure just because it's visibly shiny.
Comparing to current technology, here are some component of star wars that is possible :
- The drones
Remember the flying drones that could shoot stuff in star wars ? we already made that
- Prosthetic limb
Luke's bionic hand in star wars ? we also already made that
- The probe droids
We used a similar thing when our scientist done an expedition to the moon
Explanation:
Mechanical Advantage (MA)
MA=d1d2=FoutFin ; d1 is the distance of effort, d2 is the distance the object is moved
F=ma
As velocity is constant, a=0
So, F=0
Hope this helps!
