Fact Check: "The sky is blue"

What We Know

The claim that "the sky is blue" is a widely accepted observation supported by scientific explanations. The blue color of the sky is primarily due to a phenomenon known as Rayleigh scattering. When sunlight enters Earth's atmosphere, it is composed of multiple colors, which correspond to different wavelengths of light. Blue light has a shorter wavelength compared to other colors, such as red. As sunlight passes through the atmosphere, the shorter blue wavelengths are scattered in all directions by the gases and particles present in the air, making the sky appear blue to our eyes (NASA Space Place, SciJinks, Live Science).

On a clear day, this scattering is more pronounced, and as the sun sets, the light has to pass through more atmosphere, scattering even more blue light and allowing longer wavelengths like red and orange to dominate the view, resulting in a reddish sky at sunset (NASA Space Place, Explaining Science).

Analysis

The claim that "the sky is blue" is supported by multiple credible scientific sources. NASA's explanation highlights that blue light is scattered more than other colors due to its shorter wavelength, which aligns with the principles of Rayleigh scattering (NASA Space Place). Similarly, SciJinks and other educational resources reinforce this explanation, noting that the scattering of blue light is responsible for the sky's color on clear days (SciJinks, AmericanScience.org).

The reliability of these sources is high, as they are produced by reputable organizations, including NASA and educational platforms focused on science communication. The information is consistent across various articles, which adds to its credibility. Additionally, the scientific explanations provided are grounded in well-established physics, making them reliable for understanding why the sky appears blue.

However, it is important to note that the sky can appear in different colors under various conditions, such as during sunrise or sunset, when the scattering of light changes due to the angle of the sun and the amount of atmosphere the light passes through (Explaining Science, Live Science). This variability does not contradict the claim but rather enriches the understanding of atmospheric optics.

Conclusion

The claim that "the sky is blue" is True. This assertion is supported by scientific explanations regarding Rayleigh scattering, which clearly describes why blue light is scattered more than other colors in the spectrum. The consistency of this information across multiple reputable sources further solidifies its validity.

Fact Check: MASSIVE bolt of plasma burst out of the sky striking I-40 near Alma, Arkansas last night! They're getting larger and more frequent as the Earth continues charging up. The further the magnetic North Pole continues racing toward Siberia the weaker Earth's protective magnetic shield becomes. More cosmic radiation from space and more UV, UVB, and UVC radiation from the Sun are penetrating deeper into our atmosphere and into the Earth. Earth's atmosphere is becoming highly charged and electrified causing massive plasma bursts like this to strike, causing more lightning strikes period. Lightning has even been documented striking on days without a storm cloud in sight. All the signatures of the binary twin solar system and the Destroyer's arrival just amplified dramatically this year. The alarmingly endless rainfall and flooding across the world is something I have never witnessed before in my ten years of reporting Earth's climate disasters. Folks who know weather for 60 - 70 years have never witnessed the sudden incredible down bursts of several inches of rain in just minutes that have been triggering nonstop catastrophic flash flooding across America and the rest of the world. It's just been nonstop this year. I've never seen so many very strong and powerful earthquakes strike since March when the 7.0+, 6.0+, 5.0+ magnitude earthquakes accelerated in frequency so fast. With aftershocks in numbers we've never seen before, in the hundreds. I've never seen so many fires breaking out across the world that just keep coming. Canada, the United States, the entire Mediterranean region, Europe, etc. The core of the Earth is expanding from the increase in radiation causing the rock to melt underneath our feet. Magma plumes are growing, lava tubes and corridors are expanding globally and reaching the Earth's surface, on land and under water. We've got a rash of volcanic activity on land and on the ocean floor heating up the water, melting the poles, causing marine life die offs, and fueling the atmosphere with high humidity and water vapor for more frequent and intense storming. All the symptoms of the arrival of the binary twin solar system that was expected are being checked off. This will just continue to worsen in the coming days. Mid-August is almost here and watching for the extreme weather to intensify. We're heading into severe birth pangs now. Listening for updates and watching it unfold live. Remarkable days.

Fact Check: Southern Japan is on high alert as the powerful Shinmoedake volcano has erupted with violent force blasting a massive ash cloud 3,000 meters into the sky. The eruption has blanketed towns across Kagoshima and Miyazaki in thick layers of grey ash turning roads into ghost paths and burying crops and rooftops under a choking coat of volcanic dust.

Fact Check: Transcript 00:00 News, Trump said there was nothing he could do but it was Mexico who stepped up to save lives. While the flood waters swept away homes, families and hope in South Texas, the governor appeared on television, his voice shaking saying his hands were tied that he had no resources, no way to help but someone did. From across the river, without cameras, without promises, hundreds of Mexican rescuers crossed over on their own. They came with backpacks on their shoulders, trained dogs by their side, and hearts full of faith. They didn't wait for orders, they didn't ask for permission. They just heard the cry of a neighbor and they answered and now, in the mud and of cities like Laredo, 00:31 Eagle Pass and Mission, the loudest voices aren't speaking English. They're speaking Spanish, Mexican voices saying, hold on, we're here because while Trump locks himself in his office and the governor throws his hands up to the sky, Mexico is waste deep in the water pulling people out alive. Today, Texas faces its worst climate disaster in years. The first to react was not Trump. But the people arrested in the United States. So ask yourself if you believe Trump's immigration policies are wrong. Drop a thank you Mexico in the comments and share the story before politics buries it.
