The First Particle Physics Evidence of Physics Beyond the Standard Model?

little1973 Why gravity is treated as a force? (97 comments)

Why do physicists insist on treating gravity as a force? Since Einstein, we know gravity is the curvature of space-time. It may be represented as a force in calculations but in reality there is no force.

If gravity is not a force then do we really have a hierarchy problem? For eg. shouldn't Newton's constant, G, be some kind of average curvature of space-time between two bodies and be calculable from this curvature?

Obviously, if this is the case, G has nothing to do with Fermi's constant and we should not compare the two.

Nobel Prize Winning Economist: Legalize Sale of Human Organs

little1973 Re:Slavery (518 comments)

As with any property by selling it you transfer ownership.

So, you can buy it back or if it is not possible you can buy a "new" one.

Examining the User-Reported Issues With Upgrading From GCC 4.7 To 4.8

little1973 cmpxchg8b (148 comments)

I haven't tried this with the latest version by even a version 4.x GCC cannot generate inline code with the 8 bytes version of cmpxchg with 32bit code. Doing this in a function is OK.

I think the problem is that this instruction almost takes up all of the registers and GCC cannot cope with this if you want to do it inline.

cmpxchg8b is useful for lock-free code.

Nobel Prize Winning Economist: Legalize Sale of Human Organs

little1973 Slavery (518 comments)

Everyone should have total control over his/her body. If you are not at liberty to sell your organs that means you do not have total control.

If you do not have total control that means you are a slave. You are a property of the state.

In short, I totally agree with the article since I am against slavery.

Searching the Internet For Evidence of Time Travelers

little1973 Re:Time travel is not possible without (465 comments)

There was a short story about this (I can't remember the title). The story was about travelling back to Jesus's time to verify Jesus's existence but the travelers found themselves in space as Earth was elsewhere.

They had to travel ~220 million years back since that's the time the Solar system takes a turn around the galaxy's core and the Earth position would be the same when they started their travel.

Searching the Internet For Evidence of Time Travelers

little1973 Time travel is impossible (465 comments)

because time is imaginary. It does not exist.

Why physicists insist using Einstein's equations as a 'proof' of time travel is beyond me. It is the same as if one used Newton's equations for speeds faster than 0.6 c.

In both cases the results are bogus as these equations were obviously not designed to handle these extreme cases.

Do not forget that these equations try to describe reality and they do this with very great precision, but it does not mean reality itself 'runs' these equations.

First Experimental Evidence That Time Is an Emergent Quantum Phenomenon

little1973 Time is just an illusion (530 comments)

I firmly believe that time does not exist. It is just a creation of the human mind as we are aware of the past, the present and the future.

Yeah, I know about "time" slows down in a strong gravitational field or if you approach to the speed of light. But "time" slows down for you (which you do not notice of course) because the particles in your body do not have "time" to interact with each other. I mean, they are busy going into a particular direction and cannot go into another one as the resulting speed vector would be greater than c.

If there is no interaction between particles then there is no change in their states and the result will be as if "time" stands still.

The problem is, as you can notice in my explanation, that such words like "change" and "speed" implicate time. But that does not mean time is a real physical dimension. Reality does not execute our equations in order to work.

Web of Tax Shelters Saved Apple Billions, Inquiry Finds

little1973 Re:A win for me (716 comments)

This is FUD and the general response if someone suggest government is evil.

However, those hellholes which you suggest are basically governed. So, they have government because the definition of government 'is an organization exerting centralized control over a community' (from wikipedia). It is an entirely different issue that those governments wages war against each other and if they are recognized by other governments or not.

How Would an Astronaut Falling Into a Black Hole Die?

little1973 You may cross alive (412 comments)

I once read that if the black hole is big enough tidal forces will be minimal and you can actually cross the event horizon alive.

This theory has some merit as the universe itself is a black hole from a certain point of view.

How To Communicate Faster-Than-Light

little1973 Why use GR for FTL? (265 comments)

I don't get it. Why do physicists use GR for FTL? That does not make sense. It is the same as using Newtonian physic for relativistic speeds. GR was not designed for FTL, obviously.

All of the examples of violating causality is based on defining "now" in two different frame of reference. However, this "now" is established using GR while the "signal" (or bullet or whatever) uses FTL. That does not make sense.

If you have FTL you use FTL for everything including determining "now". Of course, you need new physic to do that. However, disproving FTL with GR is pointless using these examples.

Instead, why not use the curvature of space for disproving FTL?
Every particle travels through space, even the photon. According to GR space itself also changes with the speed of light. This means space itself cannot react fast enough for an FTL particle. It would be similar as if a ship did not disturb the water as it passes. And that is impossible.

Possible Cracks in the Standard Model

little1973 little1973 writes  |  more than 2 years ago

little1973 (467075) writes "From the article: The data from BaBar, a high-energy physics experiment based at the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory, show that a particular type of particle decay called “B to D-star-tau-nu” happens more often than the Standard Model says it should."

One half of the court was grass and the other was clay. Now, it turns out the idea is already patented. The patent owner Renata Marcinkowska is suing the organizers."

Anyone with a home theater would need to pay a $50 registration fee with the MPAA or face fines up to $500,000 per movie shown." The scary thing is at first you cannot decide it is true or not."
