During Ptolemy's time, people looked up at the sky and felt absolute certainty. Their 'now' was a geocentric universe where everything revolved perfectly around the Earth. They thought they knew everything, and for thousands of years, that was the absolute truth. Then, science evolved, and they were proven completely wrong.

​It’s a humbling reminder that our current 'now'—everything we think is absolutely correct about physics, cosmology, and the universe today—will inevitably be challenged. Some of it will be proven wrong; some of it will be expanded into things we can't even comprehend right now.

​One day, our present moment will just be 'millions of years ago' to a future civilization. What we call cutting-edge science today will look like primitive stepping stones to them. We don't possess the final answers; we are just part of the chain running the calculations forward.

If I could step inside my own brain, I would only see individual parts—isolated neurons firing in the dark. I wouldn't instantly see how those tiny pieces come together to create a massive, complex thing called consciousness. I wouldn't see me.

​We are living exactly like that right now. We look out from Earth and see ourselves as isolated fragments in a vast universe. We observe single objects—planets, stars, galaxies—but we might completely miss the much larger 'structure' they form collectively, because we are stuck inside it.

​Think about a cell inside a dog. That cell has no idea it is part of a larger, barking, breathing animal. It just knows its immediate surroundings. To truly see the dog, you have to stand outside it.

​Since we cannot step outside the universe to see what the whole thing adds up to, we are forced to try and figure out the entire picture from the inside out. Every physics simulation, every line of code tracking astronomical objects, is just us trying to map the cosmic brain from a single neuron."

This thought drives me crazy all of the time 🪶

Sound doesn’t need air; it just needs a medium.

Remember that sound waves travel fastest in solids...

Scenario one 🪶..

##rocket staging, rocket engine firing, valves flipping... ##..

When a rocket engine fires or a valve flips, it creates massive kinetic vibrations. External cameras and microphones are bolted directly to the metal or carbon fiber structure of the vehicle.

Those vibrations travel straight through the solid body of the rocket directly into the microphone sensor. It’s not capturing sound moving through the air; it’s capturing the hull shaking.

Scenario two🪶..

##Astronount space walk videos ##

If an astronaut is out on an EVA (spacewalk) and uses a tool, the vibration travels through the tool, through their pressurized gloves, or along their safety tether.

Once those mechanical waves reach the spacesuit, they vibrate the structure of the suit, which in turn vibrates the internal air.

The astronaut's ears (and their communication mic) pick up that internal air movement.

​🍀 🪶 🍀

Space is quiet, but spacecraft are not. Sound waves bypass the vacuum by using the solid structures of the hull, tethers, and suits as a highway.

Carina Nebula

Eta Carinae super nova.. The star survived.

Man [life] produces heat naturally internally therefore they have a temperature above absolute zero >0K. Hence they produce light.

🪶🪶

But light is not only composed of visible light [RED, ORANGE, YELLOW, GREEN, BLUE, INDIGO, VIOLET] but also many other like infrared, ultraviolet, X-days, Gamma-rays, Microwaves.. Plus the visible light all are under the Electromagnetic Spectrum..

But our eyes only detect the small range of visible light in that vast ocean of light.

🐾🪶🐾🪶

Experiment #1:

In your mind or literally place one life form inside an enclosed box such that that life form is not incident to any other source of light outside that box.

If you point a visible light detector like the human eye towards the life form inside that box, you will see nothing but darkness..

If you point an infrared detector like a infrared camera towards the life form inside that box, that camera will establish a large glow of light.. But in infrared form of light.

We can't see ourselves glow because our eyes only detect visible light which is a very small part of the EMS.

Electromagnetic spectrum.

🍀🐾🪶

Those planets that are invisible until light from the sun reflect from them towards you, are not invisible with the lack of sunlight.. Some or all generate or retain some heat in their cores. And therefore they are above absolute zero therefore they produce light but they still peak in infrared which is invisible to the human eye hence darkness.

Until you face an infrared camera to planet O/i/y/a [I mean random planet x] and it will detect a glow of infrared light 😵‍💫...

Then why Some Stars glow in orange-red, blue-white,...

The sun Produces light of all wavelengths but peaks at a approximately 500nm wavelength which is the green-yellow part of the visible light.. Therefore it shall appear as green yellow to the an observer with a pair of light sensors that only detects the visible part of the Ems and diffrent to an observer with a diffrent pair of light sensors that detect a diffrent part of the EMS

Same as Betelgeuse in constellation Orion that appears orange reddish only because red-orange is/are the nearest from of visible light that nears infrared that Betelgeuse peaks in.. Betelguese peaks in infrared only because of its temperature. 💔

Same as Rigel also in the Orion constellation that appears blue-white because it peaks in ultraviolet and blue-indigo-violet are the nearest visible parts of visible light that nears ultraviolet that Rigel peaks in.

Then why does man that glows in infrared don't glow in red just as Betelgeuse which also has a peak wavelength infrared..

The answer is because Infrared is also not comprised on only one wavelength but of various wavelengths that together are the infrared....

Betelgeuse produces high intensity Infrared while man/life produces low intensity infrared.

If alien X has a light sensor that detects only X-rays, they cannot see the stellar surfaces of the sun or Rigel or Betelguese 💔😔 [it's all crazy]

So we cannot say that the universe looks like this just because we see it like this using our human eyes.... Remember they {the human eyes} only see a small part of a very vast Electromagnetic spectrum. So there is a lot that we cannot see [😔😔] or see a very small portion of it.

Whatever '''''it'''''' is.....

EMS = Electromagnetic spectrum

WE DO NOT SEE IT ALL
