Earth size planet discovered orbiting Alpha Centauri B

Yes agreed. However if and that is a BIG 'if' we could develop a communications system using quantum entanglement which according to experiment seems to transmit information from one quantum particle to another faster than light, actually it’s instantaneous, no delay even across a billion light years. Yes it seems unbelievable, nevertheless experiments are underway to use QE for encryption (see 1st source ‘*’) but should also result in faster than light com. (see wiki source ‘**’)

So maybe ET exists* and is waiting on us to achieve quantum communications before they implement ‘first contact’ (face to face meeting) or any contact at all because light speed com is useless and if we are tech. backwards they wait until we get out of the caves. Lol…

*(I think the odds fairly demand that ET does exist)

Still I think we should listen by SETI type equipment. Maybe we will pick up other backwards Ets ha ahhhh’ that might be a very bad thing come to think of it!

As I said, when you do something to a particle that is entangled the entanglement breaks.

 

So what do you consider to determine the 'influence' of the Sun to estimate the edges of the Solar system? It can't be light or gravity from the Sun because these influences, although infinitesimal, can reach into other solar systems. Maybe it's the solar winds which stretch out 2-3 times the distance of Pluto from the Sun? If this can be true, then ~3.5 billion miles (*) 2.5 (=) 8.75 billion miles (/) 50,000mph (=) ~20 years.

If we can't clearly and concisely define the boundary of the Solar system, it's not clear to me how we will ever know when Voyager's have left 'the house'?

 

I know one thing; if there is ever a manned flight outside of our fledgling attempts so far, all those on board MUST be solely Democrats, or Republicans, or Independents! If we mix politics they will kill each other before they reach one AU!

We have robots in our solar system today and two of them leaving the solar system sometime in the future. The technology on these robots becomes antiquated in short order, relatively speaking. If we have a sustainable manned craft, they can receive instructions how to update their technologies; in other words the manned and sustainable craft can continue to evolve during the flight. But to build such a craft would require 50-100 years and all the money in the world!

IMO we ain't going anywhere until we discover some new physics and discover a gold mine to fund it...

 

Balls! said the Queen...IF...I had them I'd be King!!

The other thing to consider which was put forth by Drake is how long can we expect intelligent civilizations to exist? If the typical MO is intelligent species evolve, intelligent species develop weapons of mass destruction, not so intelligent species annihilate themselves, and this whole process lasts maybe 300-500 years, then maybe not too many civilizations exist long enough to acquire interstellar travel capabilities.

Regarding the above variable, and thinking about intelligent civilizations coming and going in short periods of time, or how long they might use a particular communication scheme, the chances of contacting ET at the right moment in time IMO is really small. So...I'm thinking we need to be searching for something other than Earth's 20th century radio waves; something that always will exist as a by-product of a living species...

 

Regarding space travel on an ark ship or other sustainable manned vessel, I've heard that if you could get the ship up very near to light speed, you could travel beyond the galaxy in just a few years ship-time thanks to time dilation. People could even reach the Andromeda galaxy in a lifetime that way, though time would race by back on Earth..

 

The Sun is the dominant gravitational force for a radius of 2 light years.

 

I believe what you are saying is according to one interpretation of QFT, the Copenhagen, that any attempt to measure or observe the quantum particle etc will force a collapse of the wave function bringing the particle or wave out of superposition therefore forcing it to choose either or (a particle or wave). This is called the measurement problem.

The source I provided explained that a way around the measurement problem in an theoretical mathematical model. That method should in the foreseeable future allow for information that we can use to be exchanged in quantum entanglement fashion. That said information is orders of magnitude easier to send than say a bacteria or of course a human FTL traveler or time travel to back in time. Forward time travel is child’s play in comparison and has already been done in experiment and in a very limited scale by humans.

The Sun's gravitational influence continues a long way into space even when it is not the 'dominant' gravitational force; so how will you determine when you wish to declare the Sun's gravitational tug to be null and void? And wherever this might be...is this where you believe the edge of the Solar system lies?

 

Who said null and void? I said orbit the Sun. At ranges less than 2 light years objects with less than escape velocity will orbit the Sun.

I've yet to see a scientist talk about the Oort Cloud and say it lies outside of the Solar System.

 

Actually what you said is; Originally Posted by Panzerkampfwagen The Sun is the dominant gravitational force for a radius of 2 light years.


To answer your question 'who said null and void'...it was me.

I simply asked you how will you know the edge of the Solar system as defined by gravity when the gravity of the Solar system effects the next solar system? Where is it in this gravitational tug that YOU feel it becomes null and void and therefore YOU proclaim the true edge of the Solar system?

Maybe we should have an inner or formal solar system and an outer or less formal solar system? The inner system might be defined as the areas in which the Sun and planets have evolved into round objects and the space around these bodies is cleared of most debris. The outer system might be everything beyond this that remains more under the Sun's influence than they do other influences? This would mean the Kuiper Belt and Oort Cloud would reside in the 'outer' solar system and the Sun and primary planets excluding Pluto would reside in the 'inner' solar system...just saying...

 

Stephen Hawking looking for inhabitable planets...

Project Will Scan Star System for Inhabitable Planets
January 10, 2017 - Astronomers at the European Southern Observatory say they will use one of their high-powered tools to search for inhabitable planets near Earth.

Chile Telescope to Be Used to Seek Habitable Planets in Nearest Star System
January 10, 2017 — The European Southern Observatory's Very Large Telescope in Chile will be modified in order to allow it to search more effectively for potentially habitable planets in Alpha Centauri, the nearest star system to Earth.

 

If you could observe without changing, and knew you had two entangled particles separated at a distance, one could be changed and the other would signal the change; the gods could communicate across vast distances. You could in effect say we arrived there. From what I have read, the very observation destroys.

I don’t think you can move any mass with entanglement. It made for a good book by Greg Bear though, "Moving Mars."

“Space 1999,” with a small hollowed out moon, may be the most logical means of a civilization ship.

 

I think it's great...more people and money getting excited about SETI...but they need to hurry while I'm still around...
