Interstellar Travel: How Spaceships Survive Light Speed Collisions

What does it really take to survive interstellar travel? As future spaceships approach light speed, even a tiny grain of interstellar dust becomes a devastating collision, forcing engineers to rethink everything we know about spacecraft design, radiation shielding, and relativistic travel. A grain of dust no larger than a speck of sand could strike with the energy of a nuclear weapon when you're traveling at a significant fraction of the speed of light. That means every future starship will n...
