Light does not travel infinitely far. While light can travel vast distances through space, it can be absorbed, scattered, or blocked by various materials and particles. The intensity of light decreases as it travels further from its source, eventually becoming too faint to detect. Additionally, the expansion of the universe can cause light from distant sources to become redshifted, making it undetectable with current technology. **

Light doesn't travel infinitely far because it can be absorbed or scattered by particles in the atmosphere or other mediums. As light travels through space, it can also be affected by gravitational forces and the expansion of the universe, which can cause it to lose energy and change direction. Additionally, the finite age of the universe means that light has only had a limited amount of time to travel since the Big Bang. Therefore, the distance light can travel is limited by these factors. **

Astral travel is a practice that involves the soul leaving the physical body and traveling to other realms or dimensions. It does not require physical light in the traditional sense, as it is a spiritual and mental practice. However, some practitioners may find it helpful to meditate or focus in a quiet, well-lit space before attempting astral travel in order to achieve a relaxed and focused state of mind. Ultimately, the need for light during astral travel varies from person to person and is not a strict requirement for the practice. **

Yellow light during thunderstorm conditions is often caused by the scattering of sunlight by the water droplets and particles in the atmosphere. When the sun is low on the horizon, its light has to pass through more of the Earth's atmosphere, which scatters the shorter blue and green wavelengths, leaving the longer red and yellow wavelengths to dominate the sky. Additionally, the presence of clouds and moisture in the air during a thunderstorm can further scatter and refract the sunlight, creating a yellowish hue in the sky. **

As of now, humans have not traveled beyond our solar system, which is about 4.24 light-years away from Earth. The farthest distance humans have traveled is to the Moon, which is about 1.28 light-seconds away. With current technology, it would take thousands of years to travel even to the nearest star system, Alpha Centauri, which is about 4.37 light-years away. **

Light travels at a speed of approximately 299,792 kilometers per second. Therefore, in one minute, light would travel approximately 17,987,520 kilometers. This incredible speed allows light to travel vast distances in a very short amount of time. **

According to our current understanding of physics, it is not possible for astronauts to travel at the speed of light. As an object with mass approaches the speed of light, its energy requirements become infinite, making it impossible to accelerate to or beyond the speed of light. Additionally, the theory of relativity suggests that as an object with mass accelerates, its mass increases, requiring even more energy to continue accelerating. Therefore, it is unlikely that astronauts will ever be able to travel at the speed of light. **
