Science is the activity through which we attempt to explain what we do not understand through experimentation and observation. During science’s quest for answers, we encounter mysteries of science and technology that remain unexplained.
1. The Speed of Light
The speed of light is a fundamental physical constant we have measured at 299,792,458 meters per second. Scientists have done numerous experiments confirming this measurement for mass-less particles in a vacuum. However, the more we observe the universe the more we learn about the phenomenon that seems to sidestep or violate this physical constant.
One observation scientists recently made is that parts of the galaxy are moving away from Earth faster than the speed of light. These are galaxies that are beyond what is called the Hubble sphere. Scientists explain that space itself is expanding, not matter or information through space. Theoretical physicists are claiming we might be able to have a faster than light spacecraft by manipulating the shape of space itself as opposed to moving through space.
Some physicists also describe a particle which is always moving faster than the speed of light, called tachyon particles. This would neatly sidestep the requirement of infinite energy to accelerate an object with mass because it would have never needed acceleration. However, despite experiments, none have been detected by researchers at CERN (European Organization for Nuclear Research).
