Currently, our fastest spacecraft have reached speeds of around 37,000 miles per hour (60,000 kilometers per hour). Future technologies may allow for much higher speeds.

Would you age if you traveled at the speed of light? According to Einstein’s theory of relativity, as an object with mass approaches the speed of light, time dilation occurs. From the perspective of the traveler, time would pass more slowly than for a stationary observer. This means that if you could travel at the speed of light, time would effectively stop for you, and you would not age during the journey.

Will we ever travel light years? Traveling light years, which is the distance light travels in a year, would require technology far beyond our current capabilities. As of now, it remains a concept mostly confined to science fiction.

What if an atom hit Earth at the speed of light? If an atom were somehow accelerated to the speed of light and collided with Earth, the consequences would be catastrophic. Such an event would release an enormous amount of energy, potentially causing massive destruction and altering the planet’s composition.

Is there anything faster than the speed of light? As of our current understanding of physics, nothing with mass can travel faster than the speed of light in a vacuum. However, phenomena like quantum entanglement and cosmic inflation suggest that certain aspects of the universe may appear to exceed the speed of light, but they do not violate Einstein’s theory of relativity.
