I believe, and hope to be corrected on if false, that double the distance halves the gravity?
Quarters, not halves.

Okay, let's do this.

The force of gravity (F) = G * M1 * M2 / (D squared), D being the distance between the centres of the two masses. G is the gravitational constant and in this case M1 is whatever object is on the surface of the Earth / Moon.

F on Earth's surface = F on Moon's surface. We want to find the value of M2 on the right-hand side.

We can remove G and M1 from both sides as they're common to each.

So we have:

(Mass of Earth) / (Radius of Earth, squared) = (Increased mass of Moon) / (Radius of Moon, Squared).

(5.97219 *10^24)/((6371km)(6371km)) = (Inc Moon mass)/(1737.4km)(1737.4km).

(5.92719 * 10^24)/(40,589,641) = (Inc Moon mass)/(3,018,558.76).

Inc Moon mass = (5.92719 * 10^24) * 3018558.76 / 40589641.

Inc Moon mass = 5.92719 * 10^24 * 0.07436.

Inc Moon mass = 0.447458 *10^24.

Inc Moon mass = 4.47458 * 10^23.

Actual Moon mass = 7.34767 * 10^22.

Increased Mass / Actual Mass = 6.0898.

There is some margin for error in the above figures. In actual fact, the gravity of the moon is about 16.6% that of the Earth, so the required ratio of new Moon mass to old would simply be 100/16.6 = 6.024.

So, as you might expect, the Moon needs to have gained about five times its normal mass.

Just rewatched the end. Clara was WAY out of line. Even if the Doctor always knew what would happen, him disappearing and leaving them to make the decision was one of the few times the Doctor let humanity show what they are or could be. He also (may have known that he) put Courtney on a good track. No matter, Clara blows up for nothing, at least for a lot less than other stuff she has seen the Doctor doing/not doing.

The Doctor reappeared at the exact time that Clara and Courtney pressed the button, so he knew what they would do and what would happen. He went thru this with Amy on Starship UK. He had faith in humanity. Something it seems Clara lost at the end.

Can't wait for a new companion.
Imagine a really good friend of yours up and leaving after you've just found out you need to make a potentially horrific urgent decision, telling you it's not their problem and it's about time you grew up anyway. After an hour of tearing yourself apart, weighing the options and knowing you'll end up hating yourself either way, you finally make a decision.

And then your friend turns back up and shows you that all the unbelievable stress you put yourself through was for nothing, because one of your two options actually had no downsides at all, and in fact they pretty much guessed this would be the case all along. Then they just go on and on about how proud they are of you for making that choice, and that not being there for you, even as someone to offer support, was the best thing for you. That you should be grateful that they weren't a friend when you needed one most.

TBH, I wouldn't have been minded one bit if Clara HAD hit him. And that's even without the other shittiness this season.

(plus, Beast Below was about the Doctor making a bad decision, and Amy restoring his faith in humanity. So no, not the same)
 
Actually, I think BEAST BELOW was about Amy learning how to travel with the Doctor. Noticing little things and being able to put them together.
 
Watching "The Seeds of Doom", and reflecting on this episode, I think Doctor Who is predicting a probable future. I think that government funding for manned space exploration will eventually stop and that the majority of people will be apathetic to space exploration. The costs for manned space exploration can' t be supported by one nation. When the world does go fully and deeply into climatic catastrophe, the nations of the world will be spending their money on mitigating the effects.
 
On the issue of the fight between Clara and the Doc, ...I
think part of the issue is that Clara doesn't understand their
relationship that well. Twelve's brusque manner and
frequent incomprehension of what other people are talking or
caring about has made her wonder what his motivations are.
It think it's a combination of Twelve settling in to himself and
partly an act. The Doctor has frequently been not in synch with
what people around him are thinking, but that wasn't a big
emphasis in the Smith and Tennant stories -- Eccleston did
have some of that in his brief run. Tom Baker definitely was
that way a lot, goofy and inappropriate and alien. I think at his
best Capaldi has a lot of that vibe too. It's making Clara question
whether he really cares or appreciates what he puts them through
even if for a good end.

And in terms of drama, it's kind of refreshing to have a little
bickering, we've not seen that other than a bit with Donna in
nuWho. After the love story aspects of the recent companions
it's cool to have some issues.
 
[*]The shuttle couldn't have gotten to the moon but if it could, it couldn't have carried 100 nukes.

Mr Awe

Once you've got a shuttle orbiter into a LEO parking orbit (as usual) there's no reason why you couldn't get it to the Moon IF you'd also put up a booster stage to provide the Trans Lunar Injection burn.

Homer Hickam suggested the same

I always thought any mass changes was due to whatever cosmic answer there is the Banner gaining the Hulk's mass.

I can even work with Breakaway on Space 1999, learning that our universe itself is speeding up and leaving.

The explanation is that the explosion, perhaps with the gravity intensifiers Moonbase Alpha used might have generated a field effect anomaly.

In the Space 1999 universe, there is no Dark Energy pushing things apart until the blast endowed the Moon with it--and off it went--not just travelling spatially, but encountering worlds a bit out of phase with our universe, explaining the high weirdness of the show.

Kill the Moon was just pushing that a bit.

Well, yes, that's pretty much a given, in fact we pretty much are there already. It's hardly a unique prediction, and Doctor Who certainly wasn't the first to think it up.

In the earliest outlines for Breakaway, when it was still a follow-up to UFO, the Moon's breakaway was due to the hostile aliens altering gravity so as to deprive Earth of the first line of defence that the SHADO Moonbase provided. Though frankly, if they could muck around with gravity like that, it's a mystery how we ever had a chance against them!
 
For the Sixties, when the Space Age was going full bore, it was radical for a franchise to suggest that humans would become apathetic toward space exploration. It took a beautiful creature in Doctor Who for humans to look outward; I don't know what will changed the popular perception of space exploration in the real world. (Also, remember, that when "The Seeds of Doom" was on the telly, the first episodes of Star Trek were being seen in the UK. Talk about contrasting visions of space exploration.)

Using code language works against those who use it for people like me who can google what is being said. Not everyone is tied into the texting culture, and using that slang is off-putting. If you disasgree with me, use normal language to explain why that is so. Like I said, I don't speak or write texting.

I am not the only one to pick up on the commentary about the current space exploration in this episode. I have read several reviews that mention it.

I liked the polka dot shirt. I noted the Second Doctor wore a polka dot tie in "The Seeds of Doom".

I would think they'd have to use all the nukes for the power anyway--some large array that takes time to warm up--easily destroyed if detected soon enough.
 
Here's the problem with fusion devices.

Small, safe and massively powerful.

Housefrau's are going to be screaming for fusion powered kitchen appliances.

A blender you never have to plug into the wall, or recharge ever.

Never ending fee power.

A blender with a half life of 1000 years can be turned into a bomb that can blow up a city without much effort.

Now you just have to worry about the assholes who think that blowing up cities is a good idea.
 
I like the fact that everyone had stopped exploring space. It's sadly a more realistic prediction of the future than most.

Certainly more realistic than the robust manned British space program that was exploring the solar system in the 1980's (old series)
