Speedy neutrino mystery likely solved, relativity... →
Those weird faster-than-light neutrinos that CERN thought they saw last month may have just gotten slowed down to a speed that’ll keep them from completely destroying physics as we know it. In an ironic twist, the very theory that these neutrinos would have disproved may explain exactly what happened.
Back in September, physicists ran an experiment where they sent bunches of...

[This New Scientist article is only available to subscribers so it has been presented in its entirety.]
SUBATOMIC particles have broken the universe’s fundamental speed limit, or so it was reported last week. The speed of light is the ultimate limit on travel in the universe, and the basis for Einstein’s special theory of relativity, so if the finding stands up to scrutiny,...

CERN Physicists Trap Antihydroden Atoms →
This is huge. Anti-matter is a tricky thing; when it hits its counterpart in regular matter, they two annihilate (never to be seen again).
An antihydrogen atom is made from a negatively charged antiproton and a positively charged positron, the antimatter counterpart of the electron. The objective — both for ALPHA and for a competing CERN experiment called ATRAP — is to compare the energy levels...
whoisdiego asked: What do you have to say about the argument that the Moon is shrinking?
e7v7a7n asked: about the quantum tunneling post, when you show the dark cloud that's the probability for the electron or for the entire particle? when it has to do with passing through a barrier does it mean the entire atom passes through or just an electron or two?
thanks

Also, a note to all those who have asked...
I, Carly, have recently decided to make this tumblog my new project. If you’ve submitted/asked and you haven’t been responded to, either A) your submission/question was offensively bad and was deleted or B) I haven’t been able to get to it yet and it will be got to soon.

Quantum Mechanics! →
If you liked the post about quantum tunnelling, check out the premier QM blog on tumblr by clicking the above link. It’s run by the crazy smart entangled and is all QM all the time. Go go go!

Stuff I'm Learning: Quantum Tunnelling
Hello all, your trusty friend ummwhat here. Trust me, this isn’t as scary as it looks.
Quantum tunnelling is a strange phenomenon of quantum mechanics that allows particles to pass through barriers that normally would be impassable. It all has to do with the Heisenberg uncertainty principle. This is a fundamental principle of our universe: we can never know exactly everything about a...

erimentha-deactivated20110921 asked: I have about 50 million questions regarding physics, but I'm not going to burden you with all my tedious questions. Instead, I was wondering if there are books that you know of or websites you could send me to about basic to intermediate physics. I never took physics at all in high-school, a decision I now greatly regret, because I've recently taken an interest in physics, but have...

Testing the Hypothesis of a Holographic Universe... →
The holographic principle of the universe has been a popular theory among crazies and string theorists for years.
In a larger and more speculative sense, the theory suggests that the entire universe can be seen as a two-dimensional information structure “painted” on the cosmological horizon, such that the three dimensions we observe are only an effective description at macroscopic...

Meteoroid ≠ Meteor ≠ Meteorite
fuckyeahspace:
I’d like to quickly clear up some confusion that a lot of people seem to have about how rocks in space are named.
Meteoroid:
Bigger meteoroid:
Asteroid:
Bigger asteroid:
Comet:
Meteor (not a rock, just a streak of light):
Meteorite (meteoroid on Earth):
Happy Saturday to all!
