Science can prove a lot of things that we don’t understand. This was only 20 neutrinos and since neutrinos can travel through matter without being affected, maybe the neutrinos they detected came from a distant planet, or Chicago. They refer to light particles and they indeed have nearly no mass..

The OPERA team’s initial result was based on socal green hulu kapuas observing more than 15,000 bunches of neutrinos, or electrically neutral subatomic particles. But the scientists did not track any one specific neutrino. Instead, the neutrinos were produced in long pulses that lasted about 10 millionths of a second. Two recent papers – one by Alexey Bobrick and Gianni Martire and another by Erik Lentz – provide solutions that seem to bring warp drives closer to reality.

Energy Policy

School zones through urban and suburban areas on two lane roadways normally have a speed limit of 25 mph when children are present. However, this limit can be as low as 20 mph and as high as 35 mph in some areas. During the closure and major rebuild of I-64 in St. Louis, an additional lane was added to I-44 and I-70, and the speed limit was thus reduced to 55 mph on those roads within the St. Louis County and City.

Speed Limits Reduce Deaths, But Can They Also Cause More Pollution?

Today, 41 states, including Washington, allow 70 mph or higher speeds on some roadways, Idaho is one of eight states with maximum speeds of 80 mph or more. A 2019 IIHS study found that rising speed limits have cost nearly 37,000 lives over 25 years. AAA and IIHS urge policymakers to factor in this danger from higher speeds when considering speed limit changes. BELLEVUE, Wash.— Drivers want to save time, and local transportation agencies want to improve traffic flow, but at what cost? As posted speed limits increase on roadways around the country, a vehicle’s ability to protect drivers in a crash might not be up to the task.

That is particularly important when we discuss the assumed constancy of c during the development of the universe. There is a question about measuring the speed of light, which sounds simple but is not in my view. Since all the laws of physics take the same form in terms of any system of inertial coordinates , it follows that whatever capability for superluminal signaling exists in terms of one inertial coordinate system must exist in terms of every other.

States Are Raising Their Speed Limits They Should Do The Opposite

The highest posted speed limit in New York is 65 mph (105 km/h), found only on limited-access freeways . The default speed limit, posted as the “State Speed Limit”, is 55 mph, which is in effect unless otherwise posted or in the absence of speed limit signs. Provided that no hazard exists that requires lower speed, the speed of any vehicle not in excess of the limit is deemed to be prima facie lawful. The limit for “rural residential districts” and Class V highways outside the city or town compact is 35 mph (56 km/h). The limit for any “business or urban residence district” is 30 mph (48 km/h).

Of course you can change forward and backward in time relative to some ARBITRARY coordinate time. According to special relativity, if it were possible to send signals superluminally, it would be possible to send signals “backwards” in time, and since we reject this “backward” possibility, we must reject he possibility of superluminal signaling. I think one can set an arrow of time in either direction equally well on a spacelike interval. With a timelike interval there is a clear ± sign to the direction. With a spacelike interval there is only a ± sign with respect to a spatial direction.
