For decades, scientists believed that galaxy collisions typically resulted in the formation of elliptical galaxies. Now, for the first time, researchers using ALMA and other radio telescopes have found direct evidence that galaxy collisions do, in fact, form disk galaxies, and that this outcome is quite common. This surprising result may explain why spiral galaxies like the Milky Way are so abundant in the Universe.
21 Grams... If you weigh 70 kilograms, 21 grams is the mass of all the electrons in your body. This 21 grams comes entirely from the Higgs mechanism. This means that as your electrons move through space and time, they interact with the Higgs field, and because of this interaction, they gain mass. The Higgs field slows down the electrons and prevents them from reaching the speed of light. (Higgs Boson What is the Higgs Field?) But you or […]
I'm sure everyone, including me, has struggled with constantly tangled headphones. We spend 5-10 minutes trying to untangle them before even putting them in. There's always a good chance they've gotten tangled up in your pocket. Most of the time, they come out tangled. Sometimes, they're so tangled that we wonder how this is even possible. Researchers at the University of California conducted a study on this issue and even discovered that […]
I didn't think I'd cover much in this post, but since I can anticipate the questions you might have after watching the video, I'll dive into the explanation. I recommend reading what I wrote after watching the video. In the video I've created the subtitles for, Professor Andrea Morello explains Bell's Inequality and quantum entanglement, demonstrating the difference between classical physics and quantum entanglement. To unlock the subtitles, click the full [...]
This video was created by Alexander Gerst aboard the International Space Station. He is one of 40 crew members on the International Space Station and has been in orbit for five and a half months. The video was assembled using photos taken every second at a resolution of 4256 x 2832. This high resolution allowed the ESA team to create the video at 3840 x 2160, or 4K resolution.
The sky looks delicious (!). This photo was taken by Göran Strand in Östersund, Sweden, last week. Green auroras, resembling a mushroom rising from the ground into the sky, are caused by the interaction of light with oxygen in the atmosphere. Oxygen can produce red auroras in addition to green. If ionized nitrogen is present in the atmosphere, you'll see blue auroras. Above, we see the magnificent Milky Way galaxy stretching from left to right.
