Alpha Centauri – Lifeboat News: The Blog https://lifeboat.com/blog Safeguarding Humanity Mon, 17 Apr 2017 05:27:36 +0000 en-US hourly 1 https://wordpress.org/?v=6.6.1 Debunking Antimatter Rockets for Interstellar Travel https://lifeboat.com/blog/2012/10/debunking-antimatter-rockets-for-interstellar-travel https://lifeboat.com/blog/2012/10/debunking-antimatter-rockets-for-interstellar-travel#comments Tue, 02 Oct 2012 03:08:22 +0000 http://lifeboat.com/blog/?p=5522 Previous Post in this Debunking Series.

Why is it necessary to debunk bad or unrealistic technologies? If don’t we live in a dream world idealized by theoretical engineering that has no hope of ever becoming financially feasible. What a waste of money, human resources and talent. I’d rather we know now upfront and channel our energies to finding feasible engineering and financial solutions. Wouldn’t you?

We did the math required to figure out the cost of antimatter fuel one would require just to reach 0.1c and then cost at that velocity, never mind about reaching Alpha Centauri.

The table above compiled from various sources shows that the cheapest cost of just reaching 0.1c velocity is of the order of $125,000,000,000,000,000,000. This so unthinkably large even I don’t know how to conceptualize it, and by comparison, conventional rockets appear realistic!

Also note that the large variations in the estimates of the amount of antimatter required combined with the larger variations in the mass of the spacecraft antimatter engines could propel. That is no one reallys has a handle on what this would take.

But wait, let me quote EJ Opik, “Is Interstellar Travel Possible?” Irish Astronomical Journal, Vol 6, page 299.

The exhaust power of the antimatter rocket would equal the solar energy power received by the earth — all in gamma rays (and Opik quotes Carl Sagan, Planet. Space Sci., pp. 485–498, 1963) “So the problem is not to shield the payload, the problem is to shield the earth

I don’t need to say more. Debunked.

Debunking Conventional Rocket Interstellar Travel Once And For All https://lifeboat.com/blog/2012/10/debunking-conventional-rocket-interstellar-travel-once-and-for-all https://lifeboat.com/blog/2012/10/debunking-conventional-rocket-interstellar-travel-once-and-for-all#comments Tue, 02 Oct 2012 03:01:05 +0000 http://lifeboat.com/blog/?p=5516 Previous Post in this Debunking Series.

What a waste of money, human resources and talent. I’d rather we know now upfront and channel our energies to finding feasible engineering and financial solutions. Wouldn’t you?

We did the math required to figure out how much fuel one would require just to reach 0.1c and then cost at that velocity until you reach Alpha Centauri and reverse thrust to orbit the star.

$1,122,807,017,544

Total

8.00E+13

$238,596,491,228,070

Note: 1) Fuel mass required to reach 0.1c or 29,970 km/s is twice   5,625,000*(29,979/11.2)^2,
once to accelerate 0.1c on leaving Earth and a second time to   decelerate at mid
journey to arrive at zero km/s
2) 8.00E+13 lbs converts into 36,287,389,600 metric tons

This analysis assumes that your payload is the about the same size as the Apollo 11 command, service and lunar modules with a combined mass of 46.7 metric tons. That gives you an idea of how impractically small 100 tons is for an interstellar flight.

The total cost of a conventional rocket interstellar trip is on the order of $238,596 billion! Even if we said that the costs are over estimated by 1,000x it would still costs $238 billion!

It is so unrealistic that if you search the internet the parties who say such a trip never discuss how much it will cost. The parties who say it cannot be will also point out the mass of fuel required.

I don’t need to say more. Debunked.

The next in this Debunking Series.

Only One Interstellar Travel Community Will Succeed https://lifeboat.com/blog/2012/09/only-one-interstellar-travel-community-will-succeed https://lifeboat.com/blog/2012/09/only-one-interstellar-travel-community-will-succeed#comments Wed, 12 Sep 2012 01:55:03 +0000 http://lifeboat.com/blog/?p=4961 There four camps that comprise the present day interstellar travel community and only one camp will succeed.

The first camp, the conventional rocket camp, believes it is possible using conventional rockets (chemical, ion, nuclear or antimatter) to realize interstellar travel to our nearest star Alpha Centauri. One of the problems is the costs, estimated at an unthinkably large $238,596 billion and upwards. It is several thousand times greater if we choose to use antimatter.

Further, John Eades, a former senior scientist with CERN, in his March/April 2012 Skeptical Inquirer article “Antimatter Pseudoscience”, lays down the reasons why antimatter based propulsion will never be technologically feasible.

Black Hole of wealth. One down three to go.

.

The second, the hypothesis camp, believes that there is some equation that will allow us to reach 1,000 x velocity of light and upwards based on quantum foam. Nonsense. Be very clear, the experimental evidence proves that anything with mass cannot be accelerated to exceed the velocity of light. Sure, we have hypotheses (i.e. mathematical guesses without experimental proof) that point every which way, but at best these are guesses and they have not or cannot be proven experimentally. In addition, Robert Nemiroff’s three photon discovery suggests that both quantum foam and quantum gravity may in part or whole invalidated while upholding relativity.

Wrong turn. Two down and two to go.

.

The third, the impossible camp, believes that interstellar travel is impossible. As Prof. Adam Franks stated in his July 24, 2012 New York Times Op-Ed, Alone in the Void, “Short of a scientific miracle of the kind that has never occurred, our future history for millenniums will be played out on Earth”. Obviously the impossible camp disagrees with the hypothesis camp on the basis of the physics.

Don’t argue. Three down one more to go.

.

I belong to the fourth, the new physics camp, that there is a new physics that the other three camps do not subscribe to. There are 57 of us physicist-engineers from 16 countries, US, Russia, UK, China, Japan, Romania, Austria, India and more, who have researched or are researching new propulsion technologies that are not based on chemical, ion, nuclear or antimatter engines or untested hypotheses. We search out and investigate anomalies.

Change is coming. We will be successful.

.

Based on my work as evidence, several important phenomena have been discovered

1. A new formula for gravitational acceleration that does not require us to know the mass of the planet or star. This is an immense discovery, never before accomplished in the 346-year history, since Newton, of the physics of gravitational fields, as all theories on gravity require us to know the mass of the planet or star.

2. Solved Laithwaite’s Big Wheel experiment, which nobody else could in the last 35 years.

3. Asked questions that neither relativity nor quantum theory has. For example, how is probability implemented in Nature?

Because we have learned to ask questions that the other three camps have not, we the new physics camp will find different answers and reach the stars before anyone else.

New Findings on the Antimatter Drive https://lifeboat.com/blog/2012/08/new-findings-on-the-antimatter-drive Tue, 21 Aug 2012 02:30:42 +0000 http://lifeboat.com/blog/?p=4601 Andrew Skolnick drew my attention to this great article by John Eades, a CERN senior scientist, about antimatter engines and weapons.

Antimatter Pseudoscience by John Eades in the Skeptical Inquirer http://www.csicop.org/si/show/antimatter_pseudoscience/

We, Andrew Skolnick and I, did the calculations and showed that it would cost 42,876x our 2011 World GDP to use antimatter as a propulsion fuel to get to Alpha Centauri!!

John Eades goes one better and shows that it is not technologically feasible, ever. His article is facinating reading, and shows that we cannot base our hopes to leave Earth on antimatter drives.
