Impossibility is a concept that is often relative and subjective. What may seem impossible to one person may be achievable to another with the right resources, knowledge, and determination. In some cases, certain physical or natural laws may make something truly impossible, but even then, advancements in technology and understanding can sometimes change what was once thought to be impossible. Therefore, while there may be limitations and constraints, the concept of impossibility is not always absolute. **

Package tours typically do not offer refunds because the tour operators have already made arrangements and bookings with various vendors and suppliers in advance. These arrangements are often non-refundable or have strict cancellation policies. Even though PayPal buyer protection may not cover package tours, the terms and conditions of the tour operator usually state that refunds are not provided in certain circumstances. Customers are advised to carefully read the terms and conditions before booking a package tour to understand the refund policy. **

Package holidays typically do not offer refunds because they involve multiple components such as flights, accommodations, and activities that are booked in advance by the travel provider. These components are often subject to different refund policies and cancellation fees, making it difficult to provide a blanket refund policy. Additionally, package holidays are often customized to the traveler's preferences, making it challenging to resell the package to another customer. Since PayPal buyer protection is designed for tangible goods that can be shipped and tracked, it may not cover intangible services like package holidays. **

Self-luminous bodies are objects that emit their own light, as opposed to reflecting light from another source. Examples of self-luminous bodies include stars, the sun, and certain types of light bulbs. These objects generate their own energy through processes like nuclear fusion or electrical current, which produces light as a byproduct. **

No, the luminous clock is not radioactive. The luminescence in the clock is typically achieved using a phosphorescent material that absorbs light and then slowly releases it over time. This process does not involve any radioactive materials. The glow from the clock is simply a result of this light-absorption and emission process. **

A luminous point is a theoretical concept used in physics and optics to represent a source of light that emits light in all directions. It is often used as a simplification in the study of light and its behavior, allowing for easier calculations and analysis. In reality, a luminous point does not exist as a physical object, but it is a useful tool for understanding the behavior of light in various systems. **
