Comment hidden because you are ignoring dag. (show it anyway)

Enzo, the Fermi paradox accounts for the probability of no faster than light travel. The milky way is at least 13 billion years old. That's more than enough time for thousands of civilisations to arise and colonise other stars using space ships that only reach a small fraction of the speed of light.


DFT, they really threw out most of the trappings of the 1950s original - I didn't hear any Theremin music at all. It was your typical, modern Jerry Bruckheimer style movie music - that is to say - completely forgettable.

The Space/Time/Origin sf series is an interesting look at the fermi paradox. have avoided most of the para above due to spoiler spider sence though. may re read if i watch it.

i didn't post this because i believe it by the way, i just like the clip... its amazing that they managed to get 400 government employees to testify this stuff (for the Disclosure Project). i'd like to think that for just 1 of them the report of an alien spacecraft was real. the fermi paradox makes this seem kind of unlikely though.

"btw i would rather have one nuclear power station than seven gajillion acres of inefficient turbines. They are not made of recycled paper, you know?"...

"If you like progress, and you think a fucking windmill is progress, then you're mental."

You're comparing plastics with nuclear waste and you're calling me mental? At least plastic can be recycled. Nuclear power plants aren't made of recycled paper either, and they must continually be re-fueled every 18 months. Do you think they that fuel grows on trees? Wind turbines require no fuel, and need very little maintenance.

Progress is building more safe, renewable resources for power such as wind, hydro and solar power plants, not building more nuke plants.

I know all about Chernobyl and nuclear reactors, I used to work at one. I know the designs are different, my point is that it only takes one accident and the effects on the environment and life lasts for generations. Do you realize how many nuclear accidents there have been, besides the two major ones (TMI and Chernobyl)? There's more than just accidents at nuclear plants, accidents occur during the manufacturing, transport, storage, and disposal of the nuclear fuel. They may not be as big as Chernobyl, but the damage to the environment has been done, and the "pollution" will be around longer than you or I.

Here's a list of just some of the nuclear accidents in just the US alone:

July 1959 - Boeing-Rocketdyne Nuclear Facility in Ventura County, California, A clogged coolant channel resulted in a 30% reactor core meltdown, which led to the release of the third greatest amount of radioactive iodine-131 in nuclear history.

July 1956 - Sylvania Electric Products' Metallurgy Atomic Research Center, Bayside, Queens, New York, nine people were injured when two explosions destroyed a portion of the facility.

December 1958 - Los Alamos Scientific Laboratory in New Mexico. A nuclear criticality accident killed 1 operator.

1959 - Santa Susana Field Laboratory in Simi Valley Hills, California. A partial sodium reactor meltdown occurred.

January 1961 - National Reactor Testing Station in Arco, Idaho. A reactor explosion, killed 3 technicians, and released radiation. The men were so heavily exposed to radiation that their hands had to be buried separately with other radioactive waste, and their bodies were buried in lead coffins.

October 1966 - Detroit Edison's Enrico Fermi I demonstration breeder reactor near Detroit, Michigan. A sodium cooling system malfunction caused a partial core meltdown.

November 1971 - Northern States Power Company's reactor in Monticello, Minnesota. The water storage space filled to capacity and spilled over, dumping about 50,000 gallons of radioactive waste water into the Mississippi River.

1972 - The West Valley, NY fuel reprocessing plant was closed after 6 years in operation, leaving 600,000 gallons of high-level wastes buried in leaking tanks. The site caused measurable contamination of Lakes Ontario and Erie.

March 1972 - A routine check in a nuclear power plant in Alaska indicated abnormal radioactivity in the building's water system. Radioactivity was confirmed in the plant drinking fountain. Apparently there was an inappropriate cross-connection between a 3,000 gallon radioactive tank and the water system.

December 1972 - A plutonium fabrication plant in Pauling, New York. An undetermined amount of radioactive plutonium was scattered inside and outside the plant, after a major fire and two explosions occurred resulting in its permanent shutdown.

May 1974 - The Atomic Energy Commission reported that 861 "abnormal events" had occurred in 1973 in the nation's 42 operative nuclear power plants. Twelve involved the release of radioactivity "above permissible levels."

March 1975 - Browns Ferry reactor, Decatur, Alabama. A fire burned out electrical controls, lowering the cooling water to dangerous levels, before the plant could be shut down.

1979 - The Critical Mass Energy Project tabulated 122 accidents involving the transport of nuclear material in 1979, 17 involving radioactive contamination.

March 1979 - Three Mile Island nuclear plant near Middletown, Pennsylvania. After cooling water was lost, the top portion of the reactor's 150-ton core collapsed and melted. Contaminated coolant water escaped into a nearby building, releasing radioactive gasses. A study by Dr. Ernest J. Sternglass, professor of radiation physics at the University of Pittsburgh, showed that the accident led to a minimum of 430 infant deaths.

July 1979 - Church Rock, New Mexico. A dam holding radioactive uranium mill tailings broke, sending an estimated 100 million gallons of radioactive liquids and 1,100 tons of solid wastes downstream.

August 1979 - A nuclear fuel plant near Erwin, Tennessee. Highly enriched uranium was released. About 1,000 people were contaminated with up to 5 times as much radiation as would normally be received in a year. Between 1968 and 1983 the plant "lost" 234 pounds of highly enriched uranium, forcing the plant to be closed six times during that period.

January 1980 - Lawrence Livermore National Laboratory (where large amounts of nuclear material are kept). An earthquake caused caused a tritium leak.

September 1980 - Two canisters containing radioactive materials fell off a truck on New Jersey's Route 17. The driver, en route from Pennsylvania to Toronto, did not notice the missing cargo until he reached Albany, New York.

1981 - The Critical Mass Energy Project of Public Citizen, Inc. reported that there were 4,060 mishaps and 140 serious events at nuclear power plants in 1981.

February 11, 1981 - Tennessee Valley Authority's Sequoyah I plant in Tennessee, 110,000 gallons of radioactive coolant sprayed into the containment building, which led to the contamination of eight men.

July 1981 - Nine Mile Point's Unit 1 in New York state. A flood of radioactive wastewater in the sub-basement caused approximately 150 55-gallon drums of high-level waste to overturn, some of which released their highly radioactive contents. Some 50,000 gallons of radioactive water were subsequently dumped into Lake Ontario to make room for the cleanup.

January 25, 1982 - Rochester Gas & Electric Company's Ginna plant near Rochester, New York. Fifteen thousand gallons of radioactive coolant spilled onto the plant floor, and radioactive steam escaped into the air after a steam generator pipe broke.

January 1983 - Browns Ferry power plant, Athens, Alabama. About 208,000 gallons of water with radioactive contamination was accidentally dumped into the Tennesee River.

February 1983 - Salem 1 reactor in New Jersey. A catastrophe was averted by just 90 seconds when the plant was shut down manually, following the failure of automatic shutdown systems. The same automatic systems had failed to respond in an incident three days before. Other problems plagued this plant as well, such as a 3,000 gallon leak of radioactive water in June 1981 at the Salem 2 reactor, a 23,000 gallon leak of radioactive water (which splashed onto 16 workers) in February 1982, and radioactive gas leaks in March 1981 and September 1982 from Salem 1.

December 1984 - The Fernald Uranium Plant, a 1,050-acre uranium fuel production complex 20 miles northwest of Cincinnati, Ohio. The Department of Energy disclosed that excessive amounts of radioactive materials had been released through ventilating systems. Subsequent reports revealed that 230 tons of radioactive material had leaked into the Greater Miami River valley during the previous thirty years, 39 tons of uranium dust had been released into the atmosphere, 83 tons had been discharged into surface water, and 5,500 tons of radioactive and other hazardous substances had been released into pits and swamps where they seeped into the groundwater. In addition, 337 tons of uranium hexafluoride was found to be missing, its whereabouts completely unknown. The plant was not permanently shut down until 1989.

1986 - A truck carrying radioactive material went off a bridge on Route 84 in Idaho, and dumped part of its cargo in the Snake River. Officials reported the release of radioactivity.

6 January 1986 - The Sequoyah Fuels Corp. uranium processing factory in Gore, Oklahoma. A container of highly toxic gas exploded, causing one worker to die (when his lungs were destroyed) and 130 others to seek medical treatment.

December 1986 - Surry Unit 2 facility in Virginia. A feedwater pipe ruptured, causing 8 workers to be scalded by a release of hot water and steam. Four of the workers later died from their injuries. In addition, water from the sprinkler systems caused a malfunction of the security system, preventing personnel from entering the facility.

1988 - It was reported that there were 2,810 accidents in U.S. commercial nuclear power plants in 1987.

November 1992 - The Sequoyah Fuels Corp. uranium processing factory in Gore, Oklahoma closed after repeated citations by the Government for violations of nuclear safety and environmental rules. It's record during 22 years of operation included an accident in 1986 that killed one worker and injured dozens of others and the contamination of the Arkansas River and groundwater. The Sequoyah Fuels plant, one of two privately-owned American factories that fabricated fuel rods, had been shut down a week before by the Nuclear Regulatory Commission when an accident resulted in the release of toxic gas. Thirty-four people sought medical attention as a result of the accident. The plant had also been shut down the year before when unusually high concentrations of uranium were detected in water in a nearby construction pit. A Government investigation revealed that the company had known for years that uranium was leaking into the ground at levels 35,000 times higher than Federal law allows.

March 1994 - A nuclear research facility on Long Island, New York. A fire resulted in the nuclear contamination of three fire fighters, three reactor operators, and one technician. Measurable amounts of radioactive substances were released into the immediate environment.

February 2000 - Indian Point II power plant in New York vented radioactive steam when a an aging steam generator ruptured.

March 2002 - Davis-Besse nuclear plant in Ohio. Workers discovered a foot-long cavity eaten into the reactor vessel head. Borated water had corroded the metal to a 3/16 inch stainless steel liner which held back over 80,000 gallons of highly pressurized radioactive water.

Do you honestly think that more of this is worth not having to look at a field of wind turbines (they're not windmills btw, yes I get the refrence )? As far as I know, wind turbines have not killed anyone or released toxic and radioactive materials into the environment.

An interesting article about Peter Higgs, a humble guy who says:

"Most of what has been attached to my name should not have been," he replies, "but probably the Higgs boson is correctly attached because I was probably the person who drew attention to it most in my papers. However, as far as the mechanism of generating vector boson masses is concerned, I usually write down a whole string of names, starting with Anderson and including Englert and Brout, Gerald Guralnik, Dick Hagen and Tom Kibble, and also Gerard 't Hooft."

The physicist in the video, Kim Griest, says the typical theoretical upper bound for mass of higgs boson is around 1 TeV. He, personally thinks around "1000 GeV" is where it should be, "maybe up to 2000 GeV". Yet, Jos Engelen, CERN's chief scientific officer, who's been at CERN since 1971, say's "LEP showed that the Higgs was heavier than 114.4 GeV, and we can also guess its mass from other experiments. Within the Standard Model we know that it is not heavier than 240 GeV at the 95% confidence level." Engelen says that the LHC will only be able to produce pairs of Higgs bosons if the Higgs mass is less than 500 GeV. Hmmm, I remain thoroughly confused

The New York Times has a suprisingly good, and lenghty, article about the LHC with nice multimedia:
http://www.nytimes.com/2007/05/15/science/15cern.html?_r=1&oref=slogin

CERN has a metric shitload of media and info here:
http://press.web.cern.ch/press/
- It kinda bugs me that they have such a strict copyright on their media. Isn't it predominantly publicly funded?

Perspective on collision energies:
The LEP, the predicessor to LHC, prior to going offline in 2000, topped out at --- 104 GeV.
The Tevatron at Fermi National Accelerator Laboratory is running at ---------------- 1.96 TeV.
The LHC will initially be capable of colliding beams of protons at an energy of -- 14 TeV.
The abandoned SSC project here in the US would have been capable of --------- 40 TeV.
