But gravity is everywhere.

So the chance of the electron at a given moment being say 12 billion ly away is non-zero?

Yes.  Meteor strike.  Star death.  Cylons.

Inertia is perpetual motion unless acted upon by a force.

Neither one nor the other is tuned.  There is no tuner.

When i wear a T-shirt in the summer i see faces in my sweat stains.  Once it was Hey, Kool Aid.  Once it was Jesus with a crown of thorns.

Plant Sciences, Zoology & Evolution / Re: Why do we appreciate music, from an evolutionary perspective?

« on: 28/04/2015 04:44:32 »

Sorry Yamo - don't understand the relevance!

The trait, appreciating music, was not sufficiently disadvantageous  to terminate the genetic line.  I tend to think of evolution less as survival of the fitest than as the death of the least fit.

Physics, Astronomy & Cosmology / Is there a limit to how far we can see?

« on: 07/01/2015 06:01:08 »

Is there a limit to how far from its source light from a star can be seen?  I understand that eventually universal expansion will someday exceed c but is there any other limit?

How do you measure the nothing?  Is it inferred?

Physics, Astronomy & Cosmology / Re: Can we see the future?

« on: 07/05/2013 13:48:50 »

Yes.  You see the future when you are asleep/dreaming and not blinded by the present.  Some dreams are portents.  Not everyone is good at it.  Some people have perfect recall.  Some people have perfect forecall.  Future sight is no more strange than memory.  We perceive the non present.  Take a pen and pad to bed and write down your dreams the instant you wake.  Some dreams will be of the past.  Some will be of the future.

Could an analogy to superstates be used?  Rather than measuring where the Big Deal is, collapsing the function, we are measuring where it is not.

I really hate the Monty Hall problem.  I just can't accept that changing doors makes a difference.

Likely the interesting research is classified.  Govs will never let it see the light of day, like cold fusion or nanotech..  Too many powerful people have too many trillions of $s to lose.  We are not free...not even close.

does making your eardrum vibrate count as moving mass?
