Traveling at 99.999999% the speed of light, you could in principle travel to the center of the galaxy and back in about 7 years ship time. However, observers on Earth would experience a much longer time: 52,000 years. Time dilation is a concept from special relativity.⬇️Next 1/3 Image
Time dilation describes how time appears to pass differently for two observers who are in motion relative to each other. This occurs because the laws of physics, including the speed of light, are the same for all observers, regardless of their relative motion. ⬇️2/3
Here is a great video from Cosmos by Carl Sagan explaining how you can traverse the known universe at such speeds 3/3

Why do hurricanes spin the way they do? Why do they spin in opposite directions on opposite sides of the equator? It's all thanks to our Earth's rotation and something called the Coriolis Effect! But how does it work? Let's dive in! ⬇️1/6
The surface of the Earth rotates at different speeds depending on latitude. On the equator you move faster eastward than you do close to the poles! ⬇️2/6 Image
If you were to launch a projectile southward from a high latitude, it retains its slower eastward momentum compared to the ground further south, which moves faster eastward. This causes the projectile to lag behind, curving westward. ⬇️3/6

The blue sky is a beautiful result of physics in action! But why is it blue? Why does the sky appear more orange-red at sunset? Let's dive in!⬇️1/4

Sunlight, though appearing white, is a mix of many colors. Each color has its wavelength, with blue and violet being the shortest and red the longest. Our atmosphere is mainly tiny molecules of nitrogen and oxygen...⬇️2/4

Image
When sunlight passes through, it interacts with these molecules. The shorter wavelengths (like blue & violet) scatter more efficiently in all directions by these molecules. This is called Rayleigh scattering. The scattered light then reaches your eyes from all directions!⬇️3/4

Ever wondered why soap bubbles, peacock feathers, and oil slicks display a mesmerizing array of colors? It's all thanks to a phenomenon called iridescence. How does it work? Let's dive in! ⬇️1/5
Soap bubbles consist of two layers of soap molecules with water sandwiched in between. Light reflecting off these layers interferes, either amplifying or canceling out certain colors. ⬇️2/5
Image
Image
The bubble's varying thickness causes the swirl of colors. When light waves align, they boost each other, creating brighter colors (Constructive Interference). When misaligned, they negate each other, leading to darker shades (Destructive Interference). ⬇️3/5

A simple homopolar motor that you can make at home to demonstrate Lorentz force, electromagnetism, and electric motors! How does it work?⬇️1/4
When the wire touches both the battery and the magnet, it completes an electrical circuit. Current flows (I) from the positive terminal of the battery, through the wire, and into the magnet, finally returning to the negative terminal of the battery.⬇️2/4 Image
The neodymium magnet has a strong magnetic field around it. When a current-carrying wire is placed in a magnetic field, it experiences a force known as the Lorentz force. This force is perpendicular to both the direction of the current and the direction of the magnetic field.⬇️/3

Contrary to popular belief, the majority of the Earth's oxygen isn't produced by trees but by tiny ocean plants called phytoplankton. These microscopic heroes contribute between 50 to 80% of the oxygen in our atmosphere!⬇️1/4
Beyond oxygen production, phytoplankton also play a crucial role in the global carbon cycle. They absorb large quantities of CO2 from the atmosphere, mitigating some of the impacts of climate change. When phytoplankton die or are eaten, they can sink to deeper ocean layers.⬇️2/4 NASA Goddard
In this way, the carbon they've absorbed from the atmosphere is transferred to the deep ocean, effectively sequestering it for long periods. An example is how the shell of coccolithophores locks up carbon in the form of calcium carbonate (CaCO3).⬇️ 3/4 Image

Honey never spoils! Archaeologists have even found pots of honey in ancient Egyptian tombs that are over 3,000 years old and still perfectly edible. Why is this the case? Here is a break down⬇️
1) Low Water Content: Most water in honey is bound with sugar, leaving little free water for microbes to thrive. This lack of available water makes it hard for bacteria to grow.
2) High Acidity: With a pH between 3.2 and 4.5, honey's acidic nature isn't a friendly environment for most bacteria and molds. Think of it as nature's preservative! Image
