”Light will disappear from the stars in the sky; the dawning sun will turn dark, and the moon will lose its glow. “
Many verses speak of the darkening sun and the light less moon and the disappearing stars in the sky, but is that the real understanding?
Our sun is 4.5 billion years old and he’s not ready to die yet, he still have a long life to live. He will grow brighter and brighter in the next billion years till he won’t have any more hydrogen to burn. In the meantime 10% increase in the sun’s brightness in the next billion year, will mark the beginning of the evaporation of our oceans. As the oceans evaporate, more and more water will be present in the atmosphere, this will act as a greenhouse gas, trapping even more heat and causing more and more of the oceans to evaporate, until the ground is mostly dry and the atmosphere holds the water, but at an extremely high temperature. So it seems likely that we have no more than a billion years left for life to thrive on our planet. About 7.6 billion years from now, the sun will reach its maximum size as a red giant: its surface will extend beyond Earth’s orbit today by 20 percent and will shine 3,000 times brighter. In its final stage, he would be 256 times bigger than he is now before collapsing into a white dwarf.
Stars are born and die every day in our galaxy while their light reaches us long after their present state. So most of the stars we see today won’t exist anymore by the time our sun turns into a red giant. If we look toward the galactic bulge we’ll see a whole area of newly formed stars, that’s why it’s so bright. Now if we turn toward the other side it won’t be as much because all of them are old.
We take knowledge of our satellite since our childhood, we know how it orbits earth, and we know how eclipses are formed. Some are called solar eclipses and some lunar eclipses. Total solar eclipse forms when the moon comes between the sun and earth, total lunar eclipse happens when the Earth moves in between the Sun and the Moon. As we know the Moon does not have any light of its own – it shines because its surface reflects sunlight. During a total lunar eclipse, Earth moves between the Sun and the Moon and cuts off the Moon’s light supply. When this happens, the surface of the Moon takes on a reddish glow instead of going completely dark. The red color of a totally eclipsed Moon is referred as Blood Moons. So why the red color? It is due to the phenomenon called Rayleigh scattering. It is the same mechanism responsible for causing colorful sunrises and sunsets and the sky to look blue. We all know that even though sunlight may look white to human eyes, it is actually composed of different colors. These colors are visible through a prism or in a rainbow. Colors towards the red spectrum have longer wavelengths and lower frequencies compared to colors towards the violet spectrum which have shorter wavelengths and higher frequencies, it’s why the red color is more scattered than the blue at dawn and sunrise. You may also see sometimes a reddish moon at sundown for the same reason.
“There was a great earthquake, and the sun became black as sackcloth, the full moon became like blood, and the stars of the sky fell to the earth as the fig tree sheds its winter fruit when shaken by a gale. The sky vanished like a scroll that is being rolled up, and every mountain and island was removed from its place.”
Earthquakes are measured by the Richter scale, each magnitude is a hundred times stronger than the previous one. An earthquake is the perceptible shaking of the surface of the Earth, which can be violent enough to destroy major buildings and kill thousands of people. The severity of the shaking can range from barely felt to violent enough to toss people around. Earthquakes (EQ) have destroyed whole cities. They result from the sudden release of energy in the Earth’s crust that creates seismic waves.
EQ are measured using observations from seismometers. The largest in historic times have been of magnitude slightly over 9, although there is no limit to the possible magnitude, the strongest recorded in history was In 1960, Valdivia, Chile with a magnitude of 9.5. If there was one of magnitude 12 even though it doesn’t seems likely, it won’t be enough to remove every mountain on earth, because the EQ happens in one place with one epicenter that couldn’t affect the five continents neither their mountains which are strongly welded in the tectonic plates.
We all know what stars are. A star is a luminous sphere of plasma held together by its own gravity, and our sun is one of them. Other stars are visible from Earth during the night, appearing as a multitude of fixed luminous points in the sky due to their immense distance from Earth. Historically, the most prominent stars were grouped into constellations and asterisms, and the brightest stars gained proper names.
For at least a portion of its life, a star shines due to thermonuclear fusion of hydrogen into helium in its core, releasing energy that traverses the star’s interior and then radiates into outer space. Stars are classified by their spectra (the elements that they absorb) and their temperature. There are seven main types of stars. In order of decreasing temperature, O, B, A, F, G, K, and M.
O and B stars are uncommon but very bright; M stars are common but dim. so obviously we can’t believe that real stars will Fall on earth can we?
There’s another kind of “star”, the shooting star which scientifically is called meteoroid. A small rocky or metallic body travelling through space. Meteoroids are significantly smaller than asteroids, and range in size from small grains to 1 meter-wide objects. Objects smaller than this are classified as micrometeoroids or space dust. Most are fragments from comets or asteroids.
When a meteoroid, comet or asteroid enters the Earth’s atmosphere at a speed typically in excess of 20 km/s (72,000 km/h), aerodynamic heating of that object produces a streak of light, both from the glowing object and the trail of glowing particles that it leaves in its wake. This phenomenon is called a meteor or “shooting star”. A series of many meteors appearing seconds or minutes apart, and appearing to originate from the same fixed point in the sky, is called a meteor shower. If that object withstands ablation from its passage through the atmosphere as a meteor and impacts with the ground, it is then called a meteorite.
So it’s best to think that this verse speaks of shooting stars.
It is difficult to imagine the sky rolling like a scroll, I thought at first that it might be the sky we see at night the Milky way which is a spiral galaxy, but it will never be possible for us to see it’s face – so to speak – because we’re on one of its arms. Then I thought of the end of the universe which have three theories:
The first is a closed universe which will end by a big crunch. In a closed universe lacking the repulsive effect of dark energy, gravity eventually stops the expansion of the universe, after which it starts to contract until all matter in the universe collapses to a point, a final singularity termed the “Big Crunch”, the opposite of the Big Bang. So it wouldn’t roll anything.
The second is the open universe even without dark energy, a negatively curved universe expands forever, with gravity negligibly slowing the rate of expansion. With dark energy, the expansion not only continues but accelerates. The ultimate fate of an open universe is either universal heat death, the “Big Freeze”, or the “Big Rip”, where the acceleration caused by dark energy eventually becomes so strong that it completely overwhelms the effects of the gravitational, electromagnetic and strong binding forces. Nothing to roll either.
