Maybe if you didn't spend your apparently finite amount of trust on YouTube you'd have some left over to believe something reasonable. But it's okay that you don't, I don't mind thinking you're an idiot.

And that reason would be because you're incapable of making any sense? I honestly have no idea what you're talking about. While I do make a distinction between visible and observable, that's because the article originally said "in a certain sense", so all I needed to do to show that the...

Also don't forget that a sphere won't even focus all of the light to its center. In fact it won't even reflect most of it to its center. The only way light can be reflected to the center of a sphere is if it had passed through the center already. Most of the light would bounce around for some...

By visible I mean visible in the electromagnetic radiation sense. By that, I mean that the cause itself is directly visible by either reflected or emitted EM radiation instead of relying on its interactions with other visible things. Dark matter is not visible, but is observable. So, no...

No, it doesn't say that. It says outside the visible universe, not outside the observable universe. It also says "in a certain sense", which is true, because the cause of this motion isn't visible because its location is prior to the universe becoming transparent, so it isn't visible in that...

Even if you could know everything about the state of the universe, what sort of machine would be capable of computing a future state? If you had a computer that could do it, that computer would necessarily have to contain a simulation of itself in addition to the rest of the universe. And that...

It doesn't actually say that, though. I don't see a problem with that statement.

Provided it's a one-way trip. But that raises the question of, if it's possible to get to that universe from this one, why would it not also be possible to get to this universe from that one? What would make this universe more special than the others?

If your hand is the size of a car, then yes. And it uses oxygen and a number of different fuels, mostly natural gas.

Uh, this has nothing to do with directed panspermia unless you're suggesting that we found the aliens that these meteorites belong to. It's also not panspermia since it doesn't suggest that life started somewhere else and "migrated" to Earth. Nothing on the meteorites was alive, it was just...

Especially since you can hang a lunar space elevator down below the Earth-Moon L1 point and make it easier to reach the moon.

Unless, of course, you hit escape velocity. You actually wouldn't even have to do that, since you'd really only need to get up high enough for Earth's gravity to catch you. You'd definitely need maneuvering thrusters at some point, but the fuel costs for maneuvering in the vicinity of the moon...

Probably mostly because of the relative size of the atoms of each of the metals. In the case of Steels, the carbon atoms are much smaller than the iron atoms and fit into the small gaps in the crystal lattice of the iron (an interstitial alloy). This can cause a compressive stresses in the...

Ahh, no, I understand that, I just misinterpreted what he said. I was under the impression that he was proposing some kind of "warp drive" kind of thing, not the idea that the space between two points can be expanding faster than light (because the metric expansion of space communicates no...

Are you sure? I was under the impression that one of the key assumptions in relativity is that information cannot exceed the speed of light. In fact, it comes up in the derivation of the Lorentz transformations. We even discussed how a mechanism of faster than light communication leads to a...

I've done this before, but it's always simpler in a procedural language. Granted I didn't do anything fancy with the collision detection; it was just an O(n,²) brute-force check. Creating something similar in block diagram form is a little less trivial.

It's just you. His comments have never made any sense.

He's wrong. Contact forces are a particular manifestation of the electromagnetic force. Mostly what's called Van der Waals forces which is an umbrella term for interactions between dipoles and induced dipoles (a non-polar molecule that temporarily becomes polar due to the presence of a nearby...

That's true, but I don't think that's what he was getting at because your body has the same "problem" of having to transport things everywhere. We can keep moving specialized "organs" farther away from where their needed because we keep finding ways to grow our transportation network to support...

In terms of the size of an individual, a cell, yeah, they are. If I were the size of a cell, my body would be 400 km in height. But, then, that size comparison is completely arbitrary. I mean, this is a non-sequitur. "Specialization of function is a successful design demonstrated by its...
