TED: Amazing New Discoveries Regarding Mars

dag says...

Comment hidden because you are ignoring dag. (show it anyway)

That does sound like a much better idea to me. The fact that the plane only stays up for an hour or two seems a lot of work for a very short mission. Can't help but think that the cool factor of a rocket powered mars plane is powering this project.

sending a plane is stupid... send baloons that control their altitude

> Notice the "tipping jack" popping out on the rear of the vehicle

Thats the axle of course...

Seriously though you can really tell the window and windowframe of the car has about as much mass as that air baloon they hit it with.

I agree, the requisitive suitablitiy propbablitiy factors were regulatoraly skewed to favour the victorious underpinnings of the negligent ultramodes of negatitive insitutional factories.

I like the video, but introducing physicality into a confrontation is generally a waste of time and a reckless endangerment of your interests. If someone in that vicinity was carrying a weapon, anything could have happened.
The outcomes in this video were relatively mild, but actions have to be judged on the complete probability curve, not just the manifested outcomes.

When it says that the "known universe" is 93 billion light years across, they're referring to the "observable universe". This is the part of the universe from which light has had time to reach us. Interestingly, it's possible the universe is much much larger than that. It's also possible that the universe is smaller!

I have a hard time understanding how the universe has no center. Everything I can find says it has no center and explains how the expansion has no center. I understand how the expansion has no center, but I don't understand how we can say for sure that the universe itself has no center. Can anyone explain that?


I am not a qualified physicist, just a very interested amateur and i stand to be rediculed.

This is a piece of information i recall from "a brief history of time" and it was a while since i read it. And also, i must express that the maths involved is incredibly complex for any laymen including myself to fully 'understand' quite exactly what it means, and why it is realistic to use these analogies to give anyone who doesn't understand the maths (which is the only real way of PROVING this idea).

It's to do with how you consider the universe and therefore the expansion of it. The most famous example is drawing dots on a balloon and blowing air into the balloon - the dots get further away from each other and there is no centre. The difficulty is imagining that the baloon's surface is 2d and we're talking about 3d
You can then take 4d if you incorporate time, which would be the balloon inflating, so then you're talking about the 3d dimensions of the balloon as 4d. With the time dimension being shown by the radius of the balloon.

It's a trait of humans that we're limited in our view of things. Obviously, we imagine everything exactly how our eyes percieve it. We can see 3 dimensions, so that is our universe. Maths has given us understanding of a lot more dimensions and we can experiment and 'view' them in a mathematical way, but never beyond that. Like, we can't draw a tesseract (which is a 4d object), but we can draw the shadow of a tesseract.

That's because like out in the sun, our 3d objects throw a shadow and that shadow is 2d, so the 4d object's shadow becomes 3d.

I'm getting dragged further away from my point. I'll wrap it up with Hawking's explanation of time being like the surface of a planet. With the start of time being at the north pole and the end of time being at the south. If we imagine it in this way, we can see that there doesn't necessarily have to be something BEFORE time began (the big bang). Nor even something after time ends (big crunch?). Like Hawking has said before - there's no point asking what came before the big bang, it's a nonsensical question, "It's like asking what is north of the north pole?"

Also, these concepts have been shown to be true. All galaxies in space are moving away from each other.

phlogiston says...

Memories of a 4th of July. The head of the Fire Department thought it would be a great idea to kick off the fireworks with a hydrogen baloon. It was more than they bargained for--blew out the windshield on a city vehicle and damaged the Chief of Police's hearing. He got a little time off, I think, but still has his job. Hasn't tried it again though...

Liar. I know you have a latex allergy. Or is that why you have that rash? You know what I'm talking about.

Bearded midgets, and the baloons were latex.

In reply to this comment by kronosposeidon:
Balloon Jesus appreciates your tribute to his balloon beard. He forgives you for all your balloon-related sins. BTW, what were you thinking when you had those midgets and the mylar balloons?

Balloon Jesus sees everything.

This one goes out to my balooney buddy!
