Could a Space Elevator Be Realized This Century?: A space elevator is a long-term goal that could revolutionize space access, but it remains a significant engineering challenge. The primary obstacle is building a material strong enough to withstand the immense stress of such a structure. Current research in nanomaterials, such as carbon nanotubes, may eventually make this technology feasible, but it is likely still a few decades away from being realized, if at all.
