Most Excellent Physics Community.

I think I need to rephrase this question. I'll post again in a few days.

... Hear me out, okay?

Back in 2000 I took my first solo, out of state trip, to meet an online friend. When I got off the bus, she greeted me, and let me know that we had to go stop by her friends house on the way back.

She was Wiccan and needed some Spiritual guidance because the night before she saw a black portal open up in the corner of her room that was giving her really bad vibes.

It wasn't my thing, but I never discounted it. Maybe it was real, and if nothing else it's just how her mind is rationalizing things.

But I guess my question is: Does the Scientific Method rule out the possibility that a "real" portal appeared in her room?

Taking wave function probability into account and the absense of data from the room, is it fair to say that the scientific method doesn't rule out the black portal being real?

Looking for black and white answers if possible, but I'd also love to hear your reasoning~

For those that have taken the blue pill, here is an introduction to the thinking that comes from taking the red pill. Which version makes most sense is up to you to decide. But don't automatically jump to the conclusion that your Einstein version is all that solid as a reasonable way to understand reality. Its clearly not, well that's the only possible conclusion that Dave and the AI Chatbot came to. See if you can find any errors in their logic if you believe that the Physics of Einstein is rock solid or even rational. The series of 5 ebooks is available for 99 cents on Amazon, and free on other book distributors until September 2024. The subjects covered are SR, GR, Spacetime, Speed of Light e=mc2, and some of the most famous experiments, all of which are found to be nonsense. Google "Dave vs Hal 9001"

Is it possible to determine the percentage of the gravitational force at a specified distance using only the geometry of the planet?

Example: The ISS at ~420km altitude "weighs" about 90% of what it would on the Earth's surface.

Is there an equation using only geometrical values that would give you this info?

Edit: Answered!

There is no proof that black holes contain singularities when they are generated by real physical bodies. Roger Penrose claimed sixty years ago that trapped surfaces inevitably lead to light rays of finite affine length (FALL's). Penrose and Stephen Hawking then asserted that these must end in actual singularities. When they could not prove this they decreed it to be self evident. It is shown that there are counterexamples through every point in the Kerr metric. These are asymptotic to at least one event horizon and do not end in singularities.

Researchers at the University of Ottawa, in collaboration with Danilo Zia and Fabio Sciarrino from the Sapienza University of Rome, recently demonstrated a novel technique that allows the visualization of the wave function of two entangled photons, the elementary particles that constitute light, in real-time.

Dark Energy hasn't been in the news lately, but the heat is still on.

Check out the YouTube "Dark Energy - A String Theory Way" at https://www.youtube.com/watch?v=epk-SMXbu1c and tell me what's wrong with it.

Why can't this work:

NASA uses plutonium-238 to generate electricity for satellites in its deep space missions. Using this general approach, can a car battery be continuously charged and that battery used to power a car? Sure, new tech would have to be developed, but is this idea impossible?

Derek did a retake of his controversial first video on the topic.

High-quality video by an underrated channel.

What are some other cool physics games you guys know of, whether simple or in-depth, big or small, educational or not?

Does it make sense to ask: How hard does a photon hit an object?

Does the waviness of photons make that a dumb question? If it does then what is a more correct way of conceptualizing the interaction of a photon with, for example, a light receptor? Or does the analogy in my head of a ball hitting a wall fairly represent the behavior of a photon at the moment of impact?

We are near to new physics.
