Garmin Forerunner 970 and Forerunner 570 were launched in India on Wednesday. The latest smartwatches are specifically designed for professional runners and fitness enthusiasts, and they feature AMOLED displays. They feature inbuilt speaker and microphones and have 5ATM water resistance. The Garmin Forerunner 970 smartwatches come with a claimed battery life of up to 15 days, while the Forerunner 570 is said to deliver up to 11 days of battery life.
Garmin Forerunner 570, Forerunner 970 Price in India
Garmin Forerunner 570 price is set at Rs. 66,990 in India. The Garmin Forerunner 970 is priced at Rs. 90,990. They come with a two-year warranty and can be purchased through the Garmin India website starting today.
Garmin Forerunner 570, Forerunner 970 Specifications
Both the Garmin Forerunner 570 and Forerunner 970 feature AMOLED displays with an always-on mode. The wearables support Bluetooth, ANT+, and Wi-Fi connectivity. They are equipped with an accelerometer, ambient light sensor, barometric altimeter, compass, gyroscope, and heat sensor to track fitness and health metrics.
The new Garmin Forerunner smartwatches have built-in GPS support, alongside BeiDou, QZSS, GLONASS and Galileo. They monitor blood oxygen saturation (SpO2), heart rate, stress, respiratory rate, and sleep. They have a 5 ATM water resistance rating and are quipped with an inbuilt speaker and microphones.
The Garmin Forerunner 570 features an aluminium bezel and is offered in both 42mm and 47mm display options. It delivers up to 11 days of battery life in smartwatch mode and up to 18 hours in GPS mode.
On the other hand, the Forerunner 970 model features a scratch-resistant sapphire crystal lens and titanium bezel. It has a built-in torch mode, and the wearable allows users to measure the overall energy efficiency after several runs using the new HRM 600 heart rate monitor, which is sold separately. It has a step speed loss feature that shows athletes how much they slow down when their foot hits the ground with the HRM 600 heart rate monitor. The wearable has a 47mm display.
It also offers Garmin Coach training plans for running, triathlon, cycling, and strength. It also provides a personalised readiness score offering insights about their sleep quality, recovery, training load, and more. The Forerunner 970 also suggests dynamic routes for users that loop back to the starting point.
The Forerunner 970 is claimed to last up to 15 days in smartwatch mode and up to 21 hours in GPS mode.

![Scientists Say Some Black Holes Are Born From Other Black Holes
Since LIGO’s Nobel-winning discovery of gravitational waves—ripples in spacetime—the U.S.-based detector has been picking up on hundreds of signals from black hole mergers. And, after a decade of studying gravitational waves, researchers believe a significant fraction of black holes may come from cosmic chain reactions. A recent paper published in Physical Review Letters describes an analysis of 155 pairs of binary black holes, identified by LIGO and its sisters, Virgo and KAGRA, in Italy and Japan, respectively. According to the study, about 14% of merging black holes may be what’s called “second-generation black holes,” or black holes that form from previous mergers of two smaller black holes. This “hierarchical” backstory is vastly different from the textbook version of how black holes emerge from the explosive death of a star. “Overall in the universe, black holes are merging all the time,” Cailin Plunkett, the study’s first author and a graduate student at the Massachusetts Institute of Technology, told MIT News. “Now we’re seeing a relatively consistent picture where there’s a decent percentage of black holes that are coming from this repeated pathway.”
Tracking the invisible Gravitational waves that reach Earth’s detectors typically come from extremely intense events. Over the years, LIGO has picked up some truly perplexing signals. For example, last summer it found the most colossal black hole merger ever—and if that wasn’t wild enough, the black holes that took part in the merger lie within a cosmic “dead zone” for black holes.
This zone refers to a range of black hole masses in which, physically speaking, black holes can’t form through ordinary stellar collapse. From these discoveries, astronomers realized just how little we knew about black holes, which are challenging to investigate directly. In that sense, it was a no-brainer that the ever-growing catalog of LIGO’s gravitational signals would turn up entirely new insights about black holes. “It is increasingly clear, both from individual events and population analyses, that massive black holes exist in [this] range,” the researchers wrote in the latest paper. “These observations have spurred further investigation into mechanisms that can populate this gap.”
A wobbly imprint The latest research represents one such investigation. During mergers, the two black holes spiral toward each other along an orbital plane. When one or both black hole spins are misaligned, the orbital plane can wobble, or “precess,” the researchers explained to MIT News. The degree to which the disk wobbles acts as a parameter from which researchers can measure the masses and spins of the merging black holes. One telling sign of hierarchical mergers is that they’re “lopsided,” meaning one of the pair has a much higher spin and mass than the other. For the study, the team created an analytic model to capture the kind of wobble that would have emerged from second-generation black holes. Around 14% of merging black holes followed this pattern, and the second-generation black holes identified had a very specific range of masses, at around 20 solar masses or 40 solar masses and above. Of mysterious origins To be fair, that might not sound like a whole lot. But it demonstrates that a sizeable portion of known black holes indeed follow this pattern. As for why, the team suspects hierarchical mergers emerge from dense stellar environments. Simply, when multiple neighboring stars die and collapse into black holes, the dense environment can make it easier for those black holes to find each other and merge. That could further lead to the formation of second-generation black holes. Theoretically, this could “repeat potentially ad infinitum, by virtue of the fact that you have a ton of stars and black holes in this really dense environment,” Plunkett said.
But an ensuing mystery concerns those black holes in the 40-and-above regime, which coincides with the aforementioned “death zones” for black hole masses. According to stellar evolution theory, black holes born of supernovas shouldn’t leave any black holes above roughly 45 solar masses, explained Plunkett. “Yet we have seen black holes that are that massive,” she mused. “And the question is: Where did they come from?” For now, it’s hard to say when we’ll get an answer to that question, if ever. But one thing seems to be clear: black holes are a lot weirder than we could ever imagine. #Scientists #Black #Holes #Born #Black #HolesBlack holes,Gravitational wave,LIGO Scientists Say Some Black Holes Are Born From Other Black Holes
