Possible reason for the FTL travel by neutrinos: Clock synchronization error
http://arxiv.org/abs/1110.2685


How many times will we think something is flat before we later find out we were wrong?

So, the FTL neutrino came down to them having their clocks wrong?


I always wonder what will be our "earth is flat" moment.......300 years into the future, what will those people look back on and say "what were they thinking?? lol_21st century".

Even though there is evidence supporting the big bang, I really don't think that's the answer. The ENTIRE universe existed as an infinitely small infinitely dense point? Really? I have an easier time accepting fundamental particles as existing as a wave and particle at the same time than I do believing in the big bang.

Just need to find an artist to bring it all together.
Very cool idea.

I have felt this way for a long time. It just is not at all intuitive. For some reason, I feel like the explanation for the beginning will also be intuitively sound. This is in the same line of reasoning as to why I LIKE string theory. It makes more sense for the smallest unit to be made of something, as opposed to point-particle physics that says the smallest unit is a point with no mass. It could be a string as the smallest unit. It could be that a string is the best analogy available to us. It's just that that unit be made of something, not nothing.

But saying that strings are 'it' as far as we're concerned is ok with you? I know that according to Planck, anything smaller "doesn't make physical sense" but intuitively when I see something or read about something it's rational to think that increasingly smaller pieces are responsible. Hell, even the fact that an electron or photon can only be described by a purely mathematical wavefunction sits better with me than saying that a string, a physical entity, is as small as it gets and is comprised of nothing but itself. I think I would feel better about strings if I thought about them as points of vibration giving rise to particles/forces rather than an actual "thing", per se.

A virus found in the sea off Chile is the biggest in the world, harbouring more than 1000 genes, surprised scientists report. The genome of Megavirus chilensis is 6.5 per cent bigger than the DNA code of the previous virus record-holder, Mimivirus, isolated in 2003. Viruses differ from bacteria in that they are usually far smaller and cannot reproduce on their own, needing to penetrate a host cell in which to replicate.

Story continues below, But M. chilensis is such a giant that it surpasses many bacteria in size and is genetically the most complex DNA virus ever described. It was taken from seawater sample close to the shore of Las Cruces, Chile. Its host organism is unknown. DNA viruses include pox viruses and herpes viruses, but M. chilensis "doesn't seem to be harmful for humans", said Jean-Michel Claverie, of France's National Centre for Scientific Research. The study appears in a US journal, Proceedings of the National Academy of Sciences.

A point that vibrates leads me to the question: what is doing the vibrating? Even if it is posed that these strings are made of something smaller, I prefer that the smallest part, at whatever point in the search for the smallest part we are at, is still made of something. I think that while string theory complicates some things (dimensions?), it is also in a better position to combine micro and macro physics for a reason. Ultimately, that reason is having a smallest part as opposed to having a zero point.

Again: big bang could not have started at one point. Just doesn't make sense. ;-)

Asking what is vibrating is like asking through what does a light wave propagate, or, What is the aether? I still have a hard time wrapping my head around the fact that spacetime isn't a physical entity, per se, but a metric of curvature. It is a purely mathematical construct, like a wavefunction. I started a fairly lengthy discussion on the physics forums with that very question and it seems there still isn't a definitive answer outside of the mathematical description. Well, it actually started with me asking just what light really is, but that led to a discussion on spacetime.

The reason I find this interesting is because that looks like what people describe from near-death experiences... traveling very quickly through space in a dark tunnel with a bright light at the end.

^ APOD is my homepage and I was thinking the EXACT same thing when I watched that this morning. Another very cool thought: When we die time isn't supposed to exist. Guess what? From a photon's POV, time doesn't exist. Although another possible answer to the tunnel effect is that when every optical nerve fires at the same time you see something akin to a bright white tunnel. I'll see if I can find the page, but I saw simulations of what it would look like for your visual cortex to be in overdrive and it looks a lot like artists' depictions of near death experiences.

^ Interesting. Does the optic phenomenon also account for the reported sensation of movement and blinding speed?

No. I know I've mentioned it before, but some people think the brain produces an inordinate amount of DMT just before death, and the experiences from clinical trials strongly mirror actual near death experiences. This easily explains the floating feeling.

this reminds me of our talk in the UFO thread, about how time is not true of things in themselves, but instead just a construct of the human mind to help differentiate objects temporally.

The ONLY thing, and I mean the one and only thing, that keeps me believing that time is independent of the brain is entropy. I've been thinking of ways to look at entropy in a different manner, though. Instead of a measure of disorder, I wonder what would change if we look at it as a measure of homogeneity or smoothness?
