Yes:

Maybe it is slowing down. What we see at the edge of the visible horizon was what was happening 13 billion years ago when acceleration was faster?

What do you say ?

I didn't say that space was expanding at a constant rate only that the amount of air entering the balloon was constant--what I said was as the balloon gets larger the dots on the balloon move faster and faster.

The surface area increases as the square of the radius

What is making the Universe expand is the Big Bang. What is apparently making the Universe expand faster is also the Big Bang. Let me explain. Suppose you have a balloon with closely spaced dots and you blow it up at a constant rate. As the balloon gets larger and larger the dots will separate from each other at a faster and faster rate even though the input to this process is constant.

Apply this thinking to 3 dimensions and you may have yourself an explanation for "Dark Energy".

You would think that gravity might eventually slow down the rate of acceleration--maybe it will or already has.

As I have repeatedly said: Since no one recorded the signal we have absolutely no reason to say that we were contacted by an intelligence that was not Earth bound.

One would expect an aircraft to move much more quickly than this.


At the equator, the earth is rotating at more than 1000 miles per hour.

Ok, That's interesting. My father (now deceased) was in charge of the memorial service for the Thresher at the New London Sub Base.

There is no evidence that the signal was anything other than a natural occurrence or a glitch in the equipment. If they had had the smarts to record the alleged message then we could have examined it for intelligence or a passing beep from a satellite.

A photon is a disturbance in the electromagnetic field. What travels may well be just a wave in the electromagnetic field.

Just as a wave in a sports stadium--nothing travels --only the disturbance in the seating posture of the people in the stadium.

The integration that you are referring to is cross correlation and autocorrelation and relies on the expectation of a specific pulse form and the fact that random (thermal noise) does not correlate. if you slide a square wave into another square wave then you will get the summation of the area as the one square wave slides past another. The resultant wave will be a triangular wave that is higher in amplitude than either of the square waves and hopefully above the thermal noise. Since we tend to know the spectrum of thermal noise this is made more easy.

I think that you are referring to sonar in your analogy of submarines.

Thank you

1/0 when an equation blows up or maybe the Dirac delta function?

My vote is for none of the above.


What do you mean ? We have the delicious choice of:

a kook
a crook
a crackpot
a curmudgeon



Remember that today's modality in voting is to hold your nose and vote for the lesser of two weasels.

What is the definition of a singularity. It may only be mathematically true ?

Posted 22 days ago by Profile William Rothamel
How far away are these red dwarfs ? Wouldn't we have heard from them if in fact we are close enough to eaves drop ? Unless we are lucky enough to receive a narrow hello message beamed in our direction, someone is whistling Dixie. Why would any planets be tidally locked to red dwarfs ? If so I doubt that stable temperatures would be expected there.

Who is funding this endeavor ?

It's hard to imagine a stable, nearly circular orbit with a three-body system.

Posted 23 days ago by Profile William Rothamel
This is a good starter set. I would add a nearly circular orbit and the presence of water. We could then look and see if these candidates possessed about another dozen parameters as well. My point is that you cannot select one in-range parameter and call it an "Earth-like" planet while ignoring another important dozen or more necessary conditions to be truly "Earth-like"

For our starter set--I don't think that we have as yet found a single one. They are probably out there but we need better surveillance capability.

There's a simple test to tell whether you’re more left-wing or right-wing

I question his number of stars within 1000 lightyears of Earth and most assuredly the prevalence of "Earth-like " planets. To my mind we have not yet found a one.--What do we need to see to really say "Earth-like"

Not all transmissions would be spread spectrum. Television, radar etc would not be. Also any intentional signal would not be encrypted whatsoever. I think that this is not an issue at all.
