how is it possible for NASA to establish a signal/connections so far in outer space but we can’t find signals in certain rooms in our homes?
In: Physics
Plenty of people have mentioned the difference of equipment, but the main factor is that electromagnetic waves transmit indefinitely through the vacuum of space, and without much, if any, interference.
Your house is full of wood, metal, insulation, and plaster, which get in the way, and also cell phones, game controllers, a microwave oven and maybe a baby monitor that all emit similar signals.
