You can’t travel even close to the speed of light.
At least not with conventional and practical travel methods as we know them today. First, it would take a couple of years to accelerate at a rate that your body could handle it. We don’t have a propulsion system or fuel source that could do it. Second, time dilation would change your timeline with respect to the timeline around you. We’re not really sure how that would affect a human. Third, you’d be practically blind from the visual distortion due to the Doppler effect. And finally, you’d likely explode due to an unintended collision with a tiny speck of dust.
So, if you need to travel at the speed of light, you have the following options:
- Invent a new method
- Reimagine the problem you’re trying to solve
Innovation isn’t always about going faster. It’s also about finding alternative ways to get where you need to be.
