What on Earth is Wrong with Gravity 2 of 5 - BBC Science Documentary

[ilovefacebookandebay]

I love Professor Brian Cox. .... Even when i don`t always understand what he`s talking about.!!!

[RuniScience]

@ilovefacebookandebay > I reciprocate (Respond) ... alike I like what I do not quite understand, esp by Prof Dr Brian Cox et al. ... Cheers ;-) Runi

[letsgetverydrunk]

i have to say, the animations in BBC documentaries are phenomenal. the render time for a cloud/galaxy :O... really well done. guess this is what brian means when he says "it's not about giving information anymore, it's about the sensation, the journey..." kinda sad, but at least we get these animations.

[AzumiRM]

His accent is filthy but he is a good character. I am confused :(

[gumme1234]

Why dont they just have subtitles instead of a guy filling half of the screen

"DRIVING ON THE DESERT TO DO PHYSICS!!" LOL

[HomebrewGuru]

Who is the guy dancing in front of the video

[RuniScience]

@HomebrewGuru > don't bore me with infantile comments ... this vid is posted to include the deaf and audially impaired ... If you cannot stomach it then go find this documentary somewhere else ...

[HomebrewGuru]

@RuniScience I'm just asking because he inspired me to dance while doing physics at the same time

[RuniScience]

@HomebrewGuru < Ooops. , I'm sorry for misunderstanding your comment then ...I just assumed that like the many others commenting on this video you were complaining about thetranslator for the audially impared ... For some reason many who can hear don't like sign language.

[beatboxpeej]

@RuniScience I found that awesome to see that sign language could describe really complex (or at least technical) words. Awesome. Thanks for posting.

[stiffyschlong]

@RuniScience No no no no

[stiffyschlong]

@RuniScience Bye bye! Your video is shitty in quality anyway.

they do have maps of both the earth and the moon, don't they. and know pretty much How ellipsoid they both are, and are unlikely to have put a mirror down a 10 metre crater if this is its purpose. aproximations are put into perspective with research, and if 10m didn't matter it would matter-maybe 10uM wouldn't matter that is how the scale and range of available data works.... i don't think anyof the youtube comments have quite succeeded in proving a generation of scientists wrong.

i can not stop looking at that death guy

At 2:45, I wonder if the explaination is the weight center. Neither Earth nor moon are perfect spheres. While Earth has mountains, or heavy material on a side, and water on an other side, it's weight center maybe not located in the center of the sphere. Also, that Earth can face the moon with a side that has mountains or a sea level. If a mountain such the Everest is so tall and massive, it changes both the weight center and the distance from the moon. 10 meters difference in Newtons equation

Brian, we live in an Electric Universe, not a gravitational universe. Black Holes, gravity waves, dark matter, dark energy and all this other conjured up stuff do not exist. We need to stop wasting money searching for new particles and forces invented by mathematicians. A good measure of a theory is its ability to predict the outcome of new observations or explain them without introducing additional tailor-made concepts.

[faunflynn]

fun stuff, smart also.

Kudos.

[TRYCLOPS1]

What is SPACE-TIME????!!!!! Can someone explain to me a little? Message me or just comment (If that's explainable on a comment).

[AlainG80]

@TRYCLOPS1

Space-Time is just the geometric data in the equation, see 9:09. No graviton particle has been found by particle physicists.

[RuniScience]

@TRYCLOPS1 > "In physics, spacetime (or space-time, space time) is any mathematical model that combines space and time into a single continuum. Spacetime is usually interpreted with space as being three-dimensional and time playing the role of a fourth dimension that is of a different sort from the spatial dimensions." (from Wikipedia, see "wikipedia ...Spacetime" for more background). Lots of good vids on the topic, I personally liked Prof. Michio Kaku in his docu on time...

[todomusika]

this guy's the real Sheldon Cooper

[RuniScience]

@todomusika > who the F*** is "Sheldon Cooper" ... Thanks for Comment, runi

[todomusika]

@RuniScience Never watched the big bang theory (the sitcom)? Other than that thanks for the videos! cheers!

[caveymoley]

@RuniScience character in a tv show the big bang theory. its funny u should take a look :)

[RuniScience]

@caveymoley > I would, but the battery is currently down ... Surprizing but its an anti-paradox enigma (i expend more nergy during Global Crisis Situations than is lost into the Cosmos...), will note it for future reference though, thanks... Runi

1/4 of amillions miles.. he was 10 M out (could easily be a hole like you said). And he has the cheak to call it an aproximation?.. 10m off?.. If it was 10.000 miles ok.. thats a big deal.

Has no-one ever considered they may have put the reflector in a hollow....
