Pune Indian gravitational wave astronomy has taken one step closer to studying gravitational waves, which may be able to provide direct evidence for the existence of black holes as a prototype is being built of a gravitational wave detector.

Observers in relative motion or at different gravitational potentials measure disparate clock rates. These predictions of relativity have previously been observed with atomic clocks at high velocities and with large changes in elevation. We observed time dilation from relative speeds of less than 10 meters per second by comparing two optical atomic clocks connected by a 75-meter length of optical fiber. We can now also detect time dilation due to a change in height near

As Einstein predicted, a slow drive or a step up a ladder is enough to warp time.

Kohima, Sept. 8: The department of geology and mining today conducted a seminar on artificial recharge to groundwater through rainwater harvesting, in Dimapur.

Under water lake tapping is a Norwegian technique developed in that country mainly to tap the inland lakes located high up in the mountains below their normal levels for electricity generation and drinking water supply. This technique has been used for the first time in India as well in Asian region on Koyna Hydroelectric Project Stage-IV.

Rapid visual screening technique has been resorted to for assessing seismic vulnerability and risk in the Himalayan township of Mussoorie that falls in Zone IV of the Earthquake Zoning Map of India.

In what could be the first for the country, the government today said NTPC would be duly compensated for the cancellation of its 600-mega watt (Mw) hydropower project at Loharinag Pala in Uttarakhand. The compensation could run into Rs 1,000 crore.

KOLKATA, 17 AUG: A casual approach to a serious civic issue, the rampant misuse of groundwater, might lead to massive subsidence in the city in the near future, engineers and geologists spoken to by The Statesman have said.

Though the cave-in on Council House Street today was due to the collapse of the underground brick sewer, engineers of Kolkata Municipal Corporation and the State Water Inves

Water is leaking out from the ground in Azad Maidan near CST and Marine Lines. The Brihanmumbai Municipal Corporation (BMC), which took note of the surface run-off recently, has now asked a consultant geologist to look into what might be causing the phenomenon.
