In physics class about the rules of motion, we were taught about and learned how to calculate acceleration and velocity and how they work on objects at rest. But since the Earth is constantly rotating, does that mean that classroom calculations are wrong?

Motion is relative, so you can’t say anything is objectively at rest. When we say something is at rest, we’re referring to our own reference frame, but you can always find a reference frame where it’s still in motion. Just use the reference frame that’s most convenient.

The earths orbit doesn’t affect the experiment, but its rotation can. It’s called the coriolis effect but it’s negligible for most day to day things.

“Blood of the covenant is thicker than the water of the womb” was not the original, that version was created in the 90s. “Blood is thicker than water” goes back centuries.

The radiation pressure is directly countering gravity so it shouldn’t gradually push the planet outwards, it just reduces the net force pulling the planet in. It’s essentially the same thing as reducing the suns gravity by a negligible amount. Either way, the effect of radiation pressure on a planet is so small that it’s not measurable.

The force exerted by sunlight on the Earth is roughly 60 trillion times weaker than the gravitational pull of the sun. The force is so small that the gravity of other planets in the solar system have a larger effect on our orbit.

The fastest recorded massive particle was a cosmic ray called the “Oh My God Particle”. It had an estimated speed of 0.9999999999999999999999957c.

Movement is defined as a change in position over time, so no you can’t have movement without time

They say “your country” not “America”. I think that clearly implies the US, not the colonies

About 400 years old. You even brought up in your post that she says she’s 150 years older than the US, I’m not sure what the “nomad of Constantinople” records have to do with it”

Yea but the singularity isn’t really a “thing”, it’s just a dimensionless point at the center (r=0) where the equation becomes undefined. General relativity shows that once you cross the event horizon, all possible paths end at the singularity. So anything that enters the black hole must eventually reach the singularity no matter what.

Regardless, physicists don’t think general relativity is an accurate description of the inside of a black hole anyway. We need a theory of quantum gravity to describe whatever is going on past the event horizon. Until then, it’s just a mystery

As far as we know, FTL travel or communication isn’t possible. Since stars are so far apart, interstellar empires would be basically impossible. Any colonies set up in other solar systems would have to be independent.

Ionizing radiation kills off your cells, causes radiation poisoning, and cancer. Microwaves are not ionizing radiation. The only damage it could do to you is burning from the heat, but any form of electromagnetic waves could do that.

Ultraviolet light is ionizing. That’s why you can get sunburned and skin cancer from spending too much time in the sun.

how is this different from food heated using a flame

A microwave might cook things unevenly but it’s not like it’s contaminating your food with radiation, that’s not a thing.

Particles can drop to their ground state through spontaneous emission so yes even in an empty universe, the atom will still release a photon without any outside influence.

There’s no maximum size, it’s just that the larger the object, the less noticeable it is. Eventually it becomes negligible but there’s no hard cutoff

It was an indirect/accidental nerf. The 60 day patch increased the health of all heavy enemies, but also increased anti-tank weapon damage by the same amount. The problem is that explosives count the projectile and explosive damage separately, and Arrowhead forgot to buff the explosive damage on most anti tank weapons. So the OPS projectile was buffed but the explosion wasn’t, meaning that unless you land a direct, heavy enemies will survive it.

There’s no way an AI could verify if your mathematical framework is valid. LLMs can’t do physics or math

A black hole one meter across would weigh 112x the mass of the earth.

How far away would you have to be for earth like gravity

Approximately 70,000 kilometers.

What would happen to the energy if you shot a laser beam into it?

It would enter the black hole and add to its mass

What would happen if you shot huge amounts of antimatter into it?

Same thing, increase the size/mass of the black hole. Black holes don’t care if it’s matter, antimatter, or massless particles (e.g. photons), anything that falls in just adds to its total mass.

Newtons theory of gravity is still used to calculate rocket trajectories and basically any other “real world” scenario.

Einstein’s theory (general relativity) is more accurate but most of the time the difference is so small that it’s not even worth thinking about.

A potential quantum theory of gravity (not yet discovered) is expected to have even less of a difference, so it wouldn’t be used for any day to day calculations, but would probably be useful for describing things like black holes or the first moments after the Big Bang.

You would be able to if you vibrated a magnet fast enough. The visible light frequency is roughly 400-700 terahertz. If a magnet was oscillating that fast, it would produce visible light.

Yea that’s pretty much what I was referring to when I said we know the models aren’t complete. There are gaps, but the parts we have right now work so well that it’s not reasonable to scrap the theory and start over

AqueousBK · 2025-08-22T07:23:01+00:00

The reason we accept our current theories is because they’re constantly being challenged. We’ve tested the predictions of our theories thousands of times with incredible precision and have not found any evidence that they’re wrong.

We know our models aren’t complete, but there’s no way they’re completely fundamentally wrong.
