Comment Size of the unobservable universe (Score 1) 213

I was watching a Youtube video that mentioned the size of the universe suggested by inflation models, can't find the video but here is a 2010 science blog that is in the same ballpark:

"Based on what we currently think about inflation, this means that the Universe is at least 10^(30) times the size of our observable Universe! "

http://scienceblogs.com/starts...

I remember the number being 10^28, but these are just guesses... but still, that puts the relative size of the "actual" and observable universe at almost the relative size between YOU and a PLANCK LENGTH. (well, 10^35, but close!)

Comment I would be happy if I wasn't so bitter. (Score 1) 115

You know what would have REALLY been able to "see back to the beginning of time"? A proper gravitational observatory like the LISA/Pathfinder project, which would have used three satellites to measure fluxuations in space-time less than the width of an atomic nucleus. It was planned to be operational by 2015 and would have been able to "see" better and farther than light-based telescopes.

But I probably will never see anything as cool as that, because it lost funding when the Webb sucked up all the oxygen in the room.

First, the guy is a Canadian, not an American.

Second, as he CLEARLY STATES IN THE ARTICLE, his device does *not* record images by default. The only reason it recorded images is that when he was assaulted and his system was damaged, it stopped over-writing images in the buffer, which were then recovered later.

Bloke was being who he is: a geeky techno pioneer with a focus on developing augmented sight for the seeing impaired.

You, sir, are the dick.

Comment An alternative to DM: MOND (Score 2, Interesting) 125

I like to think I have an open mind when it comes to cosmology, but I've never liked the Dark Matter "theory". If they ever find direct evidence, fine, but I will remain unconvinced until then.

My personal favourite alternative hypothesis is called Modified Newtonian Dynamics, which is based on the idea that gravity exerts a stronger pull between objects that are more or less in the same inertial frame (ie at very low relative accelerations, that "acceleration is not linearly proportional to force at small values").

Obviously, a lot of people find this blasphemy, but I don't see what is so bad with modifying the law of gravity as compared to invoking "ghost matter".
