Since the speed of light in a vacuum, which is approximately 186,000 miles per second is also the cosmic speed limit for any object with mass. According to the theory of relativity, it's impossible to accelerate any material object up to the speed of light because it would require an infinite amount of energy to do so.
Currently, the fastest humans have traveled through space is about 24,790 miles per hour relative to Earth, achieved by the crew of Apollo 10 on their way back from a lunar orbit in 1969.
As an object with mass approaches the speed of light, its relativistic mass increases, requiring more energy to continue accelerating. This makes it impractical to reach speeds close to the speed of light with current technology and known physics.
Thus in conclusion your question is a valid one for this layman, and science has a lot of splainin' to do to justify their calculations, I would conclude, because we are reaching numbers that are beyond my ability to calculate.
Thanks for the early morning headache. 🤣🤣🤣🤣🤣
The light we see now was emitted before they were that far away.
UFOs are spotted thousands of times by credible observers. They don't behave like anything we can build. One intelligent conclusion would be to suspect they come from far away. Due to our theories of the cosmos, many say that is just plain impossible. Yet, they are clearly being observed. Rather than place those theories under suspicion, the UFOs were simply ignored.
Your recent quandary with essentially the very same issue does raise the eyebrows. I suppose it is best to assume what is observed isn't true, so just ignore it. Rather than questioning the quality of our knowledge, the proper scientific response is to ignore your lying eyes.
