We are here to tell you how much time it takes for sunlight to reach the surface of the earth.

There is a speed which is considered constant at which the sunlight travels in space, i.e. traveling in vacuum, it can be said that it almost never changes and it is because of this great work that That the rays of the sun do not take long to arrive. reach. Come here on earth

It takes only a few minutes for sunlight to penetrate the Earth’s surface. But do you know how long it takes for sunlight to reach our planet?

When scientists report that it takes minutes for sunlight to penetrate Earth’s surface, this is a calculated average that does not take into account the time it takes for other types of particles, such as particles, to leave the solar core. take photons.

In the same way you have to think about the timescales the universe takes to point to the existence of galaxies millions of light years away, so it’s important to say that the light we see on Earth could have come from the surface. , of these stars millions of years ago. It’s been a long time, hasn’t it?

time we don’t see

Mathematically, the Sun’s light travels at 300,000 kilometers per second in a vacuum, while the Earth orbits the Sun at a distance of 150 million kilometers.

Do you know that if one day the Sun disappears, we won’t know it until much later? Yes, we will not suddenly notice the absence of our solar star. Even if the fusion of hydrogen into helium in the solar core was inhibited, it is quite possible that we might not notice it for a few years.

Sun Star
Everyone knows that the Sun is very far from the Earth, but how long does it take for its light to reach the Earth’s surface?

Using math it’s easy to figure out how long it takes light from the Sun to reach Earth split the speed of light in a vacuum (300,000 km/s) from the distance between the Earth and the Sun (150,000.000 km)With this we reach the 500 second mark, the result being 8 minutes and 20 seconds. it is not surprising?

The calculation is simple, the time is not that big or that small, however, this calculation does not take into account the time photons to get out of nuclear solar, And why are these particles not included in the calculations? It’s a complicated thing, as it involves particles that wander about in the star’s interior until they eventually manage to reach its surface and then travel through space.

What are photons from the Sun?

Photons that wander in the interior of the Sun until they reach the surface capable of carrying fundamental particles and light and all types of radiation, By the way, it is worth noting that lPhotons begin as gamma radiation, being emitted and absorbed many times within the solar radioactive region.

This is the reason why these photons in the Sun take time to leave the star, as they travel a long way. It is noteworthy that the sun produces these types of particles. nuclear fusion of atoms who are inside An interesting fact is that from its production to its departure from the star, photons spend about 100,000 years.

sun neutrinos

Other particles produced in the Sun are called neutrino, They also originate from the Earth’s core and are so named because they do not interact with matter. Therefore, they are able to pass by the Sun immediately after its formation, i.e. the opposite totality of photons.

Although it sounds simple and less complicated, it was the existence of neutrinos that allowed scientists to unlock some secrets about the Sun, such as: The speed at which light from the Sun reaches the Earth’s surface.

even from the presence of neutrinos in the sunIt is possible to say that yes, it will be a long time before humanity really feels the consequences of a solar apocalypse,
