Understanding the Speed of Light Barrier
For centuries, humans have been fascinated by the possibility of traveling at incredible speeds, exploring the vastness of space, and discovering new worlds. However, according to the current understanding of physics, traveling at the speed of light or beyond is a physical impossibility. But what if we could find a way to overcome this barrier?
Theoretical Limitations
According to Einstein’s theory of special relativity, as an object with mass approaches the speed of light, its mass begins to increase. If an object could reach the speed of light, it would become infinitely massive and require infinite energy to maintain that speed. This makes it a significant challenge to achieve such speeds.
Relative Motion
However, there is a sense in which we could move at a speed close to the speed of light. Our planet and everything in the universe are constantly moving. The Earth rotates and circles the Sun, and even our galaxy is in motion. It is possible that if we were moving away from a galaxy very quickly (and that galaxy was also moving away from us) we would be moving, relative to that galaxy, at a speed close to the speed of light.
Warp Drive: A Theoretical Solution
Theoretical physicist Miguel Alcubierre developed a theory in 1994 that suggested that a bubble within spacetime could distort distances, making it possible for faster-than-light travel. This idea, although theoretically sound, was considered impractical by many. However, some teams believe it might be possible to use “traditional and novel gravitational techniques” to create a warp bubble using known physics.
Challenges and Limitations
Even if we could get our hands on exotic matter and/or some technological revolutions, there are other laws of physics that could prevent the warp drive from becoming a reality. One of them is that they could collect matter while deforming and they would have to release it when they slow down, potentially destroying the place they were going when they arrived.
Visual Effects of High-Speed Travel
If we were to travel at a speed close to the speed of light, we would experience a visual Doppler effect similar to how an ambulance speeding by with its siren on appears to change its pitch as it moves. Moving towards an object would make it appear bluer, as its wavelength is visually shortened. Moving away from an object would do the opposite, changing its appearance to redder.
Physical Limitations of High-Speed Travel
We do not know what impact prolonged exposure to a high level of acceleration force would have on the body. 12 straight months of acceleration force, beyond what we are made to endure, may test not only the limits of physics but also our own physical limitations.
