Light, quantum physics, and our everyday lives
In our rapidly developing world of technology and science, we often encounter terms that seem distant from our everyday lives. Yet some of these seemingly abstract concepts have a direct impact on our daily activities and even on natural processes that we take for granted. One such concept is quantum tunneling, a phenomenon that plays a key role in a range of fundamental processes from photosynthesis to nuclear fusion.
Immense reach of the speed of light
The fundamental pillar of modern physics is the limitation of the speed of information propagation by light. This rule, that no information can travel faster than light, is universal. It applies not only to photons emitted by stars but also to electrons in electrical circuits, which are behind the creation of Bitcoin, and to sunlight that enables photosynthesis in plants. This principle remains valid even when considering quantum entanglement, a phenomenon that at first glance may seem like the ability to surpass this speed limit.
Quantum Tunneling: The Phenomenon That Drives Life
Quantum tunneling is a process in which a particle is able to pass through a barrier that it would not be able to overcome under normal conditions without sufficient energy. Thanks to the wave nature of particles and the possibility of existing in a superposition state, the probability that the particle will be found on the other side of the barrier is non-zero. This seemingly miraculous process is of fundamental importance for a number of natural phenomena:
- PhotosynthesisQuantum tunneling allows electrons in plants to jump over energy barriers, which is crucial for the efficient use of light energy for nutrient production.
- Nuclear FusionIn stars like our Sun, quantum tunneling allows atomic nuclei to overcome repulsive electric forces and fuse together, releasing an enormous amount of energy.
- Radioactive decay
And tunneling also plays a role here, when particles leave the nucleus before they have enough energy to overcome the nuclear forces.
- Scanning tunnel microscope: This device, which allows viewing the structure of atoms on the surface, uses quantum tunneling to obtain images of atoms and molecules.
Relativity of simultaneity and our view of the world
Quantum tunneling is not just a fascinating scientific discovery; it is also an example of how the relativity of simultaneity, a concept from Einstein's theory of relativity, expands our understanding of the universe. According to this theory, what is simultaneous for one observer may be delayed or premature for another, highlighting the complexity of our perception of time and space.
Understanding these principles not only leads us to a better comprehension of the universe but can also inspire innovations in technology and medicine. As we continue to study these phenomena, we can expect our view of the world to become increasingly complex and nuanced.
