The Red Kangaroo is TERRIFYING

New pressure method captures 99% of CO2 for just $26 per ton


"In each stage, more of the carbon dioxide bubbles out and can then be compressed for permanent storage in underground formations."

That sounds like a drawback to me.  Underground storage is likely to be expensive, and it may not be truly permanent, since CO₂ could potentially leak out.

I strongly believe it's a shame to waste carbon dioxide.  It's a valuable resource because it acts as plant food, boosts crop yields, and contributes to the greening of deserts.  It also warms the planet slightly.  Before that warming becomes a serious problem, we reportedly will likely run out of fossil fuels — in roughly 125 years.  Most fossil fuels may be depleted by around 2100, and we have only about 50 years of oil reserves left.

14 Forgotten Sci-Fi Films Of The 1980s That Predicted The Future

https://www.youtube.com/watch?v=cKHMQSJ3Sec

Most of these movies are not particularly good.

In the comments section, people complained that the narration is AI generated, which is ironic.

I don't think that the video is as insightful as it claims to be.  Common tropes of science fiction going back a hundred years, such as the movie Metropolis, are about the over reliance on technology, machines that can think for themselves, and those machines turning on their creators.  In fact, it is hard to find science fiction that doesn't touch on at least one of these ideas.

Hardest Part of a Rocket Launch

Shape of a photon

https://www.youtube.com/shorts/Y_Z3vq3l5zU


It seemed questionable to me that photons would have a shape.  Photons are electromagnetic waves.  The picture describes the shape of the wave in a particular circumstance.

If I can make an analogy, the subatomic level is like the surface of a turbulent ocean.  All matter behaves like waves.  Most of what is going on we can't perceive, and we only see the big waves.


No, photons do not have a fixed, measurable volume because they are quantum particles that also behave as waves. While they can be confined to a specific region of space, they are not point-like objects with a defined surface. Instead, their "size" is better understood by their wavelength and frequency or as a probability distribution of where the photon is located. 
Why photons don't have a volume
  • Quantum wave-particle duality: 
    Photons exhibit both wave and particle properties. As a wave, they don't have a discrete volume like a ball but exist as a disturbance in an electromagnetic field. As a particle, they are an elementary excitation of that field, not a point-like object with an intrinsic size. 
  • Probability, not a physical boundary: 
    The "location" of a photon is described by a probability distribution, meaning there isn't a hard edge you can measure. A photon doesn't have a "shell" that occupies a specific space, so you can't measure its volume directly. 
  • Wavelength and frequency: 
    A photon's properties are described by its wavelength and frequency, not its volume. For example, high-frequency photons have a shorter wavelength but are not considered "smaller" in a volumetric sense. 
  • Confined but not a fixed size: 
    While a photon can be confined to a specific region (for instance, in an optical cavity), the photon itself is not what gives the cavity its volume. Instead, a photon with a certain energy can be thought of as existing within that space, much like a wave can exist within a specific area of a pond.

Can lifting weights keep your telomeres young? The science behind it

"More time spent on strength training was linked to longer telomeres."

https://www.yahoo.com/lifestyle/articles/lifting-weights-keep-telomeres-young-191427952.html

There is a difference between correlation and causality.  It might be that people who lift weights have healthier lifestyles.

However, everybody tells us  to do strength training as we get older.

Why Our Solar System Shouldn’t Exist…

https://www.youtube.com/watch?v=CZfLZ1EoRGk

Reportedly, gas giants can move toward their star in a process called planetary migration. This movement can disrupt the inner planets of a solar system, sometimes even flinging them away from the star. However, the theory is that this didn't happen with Jupiter because Saturn's gravitational pull counteracted its inward drift. As a result, Earth remained in its ideal position—and life was able to develop.

I didn't know its use was so common.

I have no desire to alter my consciousness and possibly damage my brain.  Even if it is "fun", there are other ways to have fun.   My opinion is that any form of intoxication just makes us dumber.

I have taken pain medication when I have needed it, but I would rather not take it if I don't have to.

Honey - Mayo Clinic

Safety and side effects

Honey is likely safe for use as a natural sweetener, cough suppressant, and topical product for minor sores and wounds.

Avoid giving honey — even a tiny taste — to babies under the age of 1 year. Honey can cause a rare but serious gastrointestinal condition (infant botulism) caused by exposure to Clostridium botulinum spores. Bacteria from the spores can grow and multiply in a baby's intestines, producing a dangerous toxin.

Some people are sensitive or allergic to specific components in honey, particularly bee pollen. Although rare, bee pollen allergies can cause serious, and sometimes fatal, adverse reactions. Signs and symptoms of a reaction include:

Is your Protein Powder safe from Lead?


There are similar issues with dark chocolate, where the California standards are too strict.

The Universe Is Speeding Up...


I get the sense that we don't fully understand how the universe works.  Maybe in 100 years we will have it all figured out.
