The Laws of Gravity - Richard Hammond Builds a Planet: Preview - BBC

I didn't think this would even be possible, the height of the tower makes Hammond look even smaller.

I Also Love Watching How Planet Earth is Formed

[cyanuranus]

I Love How Planet Earth is Forming from Accretion. It's How the Heavy Particles or Dust Grains are Condensing to Become the Terrestrial Planets. Because Heavy Elements like Iron, Nickel, Carbon and Silicon are Condensed at High Temperatures to Form the Terrestrial Planets. Or the Dust Grains are Sticking Together in a Process Called Static Electricity. They Form into Chunks of Rock and Metal. Then They Become into Planetesimals

I'm personally a dental student with not much knowledge in physics -but this is my opinion: gravity is just a force of attraction, and as such, you can have many forces acting simultaneously, e.g. the sun is attracting earth, but the Earth is also attracting the moon.

So in other terms, if there was no gravity between the dust particles, they would all just follow the same elliptical path and orbit around the main object, but because of the inter-gravity present, they collide and merge :)

Keep going. I really enjoying reading your comments. Full of info. Share your wisdom sensei.

[blackheartedartist]

this looks so good, i can't wait for it

[RandomDanStuffses]

That is true, but if there was no gravity, there would be no orbit. Since there is no force between them (unless you count the strong nuclear, which is so infinitesimally small it doesnt matter) they would all just float off to infinity. Once you add Gravity then they would orbit ;) But also attract each other.

[taresz]

When you see the whole program you will understand. Those rocks are orbiting around the tower for only demonstration purposes. Explained.

[BenWillock]

Why didn't they just hire Dr. Brian Cox then? He's a well known tv personality and is an actual physicist.
The reason the BBC hired Hammond is because he has connections within the BBC, and its the reason we have had the same people on the BBC for years.

[taresz]

Because that makes a lot of sense! lol

[RandomDanStuffses]

Well I'm not exactly going to bother posting if there's nothing important to say. You'd do well to pay attention.

[taresz]

You should cultivate real-time paradigms then.

[RandomDanStuffses]

"Lets add gravity to our orbiting cloud of dust" so... how's it orbiting without gravity before you add it? Explain that one.

[RandomDanStuffses]

I do actually, I'm just not applying it here because I simply don't care. Its the internet. If you had any kind of sense you'd stop replying, or apologise and drop it. Instead YOU are the one who doesn't seem to know when to stop... don't try and use that one on me.

[RandomDanStuffses]

Its strange, I'm only reading your response as gibberish.

[RandomDanStuffses]

No, I'm alright. I would respond to your ignorant comment about spacetime, but it'd only make you try to correct me.

[taresz]

You have made a comment about the program without watching it and you were wrong. That is what i responded to. I took the spacetime answer off because it i realized it was irrelevant. Bye.

[RandomDanStuffses]

You're assuming that I don't realise this is a TV program. Of course it is, the entire premise of the show is totally impossible and ridiculous.

[RandomDanStuffses]

Ah yes, I'm digging aren't I? Into what may I ask, since as far as I'm concerned, there are no consequences to proving someone right on the internet. Its merely fun to watch them (you in this case) come up with effortless, and somewhat irrelevant responses. Like that one.

[RandomDanStuffses]

Oh boy, how you don't...
This is my point, it seems you can't take your own advice either.
You could also attempt to make an effort when replying, it's just not as fun when you drool that kind of playground kind of remark out.
