Amidst the excitement surrounding the release of Tesla’s Cybertruck on November 30th, potential buyers with the intention of reselling should exercise caution. Tesla has introduced a substantial penalty for customers attempting to resell their newly purchased Cybertruck within the initial year of ownership, as outlined in a newly added section of the vehicle’s order agreement.

“You agree that you will not sell or otherwise attempt to sell the vehicle within the first year following your vehicle’s delivery date,” the company wrote in the legally binding document.

According to Gizmodo, the clause states that resellers of the Cybertruck, Tesla’s long-awaited electric pickup truck slated to begin delivery on November 30th, could be barred entirely from purchasing Tesla vehicles ever again. Tesla also threatens legal action against resellers, seeking injunctive relief of at least $50,000. Elon Musk’s electric vehicle maker asks anyone who wants to dump their Cybertruck to sell it back to Tesla or receive written consent from the company before selling it to a third party.

Tesla will be making three models of the Cybertruck, a vehicle that can accelerate from zero to 60 miles per hour (100 kilometers per hour) in less than three seconds. The basic model will cost $39,900 (roughly Rs. 32,03,700) and offer a 250-mile range between charges; the top-line truck will have twice that range and sell for $69,900 (roughly Rs. 57,41,900).

Two siblings, aged eight and six, drowned in the Tawi river in Jammu, officials said on Tuesday.

The siblings — eight-year-old Nadiya and six-year-old Ismael — were grazing cattle on the riverbank Monday evening when they slipped and fell in the river in the Har Ki Pauri area of Jammu city.

Their bodies were recovered Tuesday evening during a rescue operation jointly launched by the police and the State Disaster Response Force.

The bodies were handed over to their family after legal formalities, the officials said. 

Scientists have made a remarkable discovery from a black hole that lies more than 25,000 light-years from Earth and is four million times more massive than our Sun. Astrophysicists Gustavo Magallanes-Guijon and Sergio Mendoza of the National Autonomous University of Mexico have recorded the supermassive hole “pulsing” every 76 minutes like clockwork, as per a report in Science Alert.

The gamma-ray of the black hole named Sagittarius A* is fluctuating and is similar in periodicity in changes to the black hole’s radio and X-ray emission. The scientists therefore suggest that there could be an orbital motion of “something” moving around the black hole. 

As per the outlet, there is currently no radiation that can be detected from black holes. The shadows are so black that they are not visible to the telescopes used to examine the light that streams through the universe. However, it is to be noted that several events can occur in the severe gravitational regime outside the black hole’s event horizon. Astronomers have also detected a pattern from the region of the blackhole as light is emitted in a multitude of wavelengths and “the strength of that light varies significantly over time.”

In 2022, it was found that radio waves vary around 70 minutes. Further, a 2017 study revealed that the X-ray flares from the black hole had a periodicity of 149 minutes. That is almost twice as periodicity of the variations in radio waves and gamma rays.

In 2021, Sagittarius A* was connected to gamma radiation. Both scientists believed that the gamma-ray data may contain some mysteries. They found that every 76.32 minutes, according to the black hole “lets out a flare of gamma radiation” which was dubbed as the “most energetic wavelength range of light in the universe”.  According to the researchers, the periodicity of the radio flare and the gamma-ray flare are nearly identical. It seems unlikely that the X-ray flare’s double periodicity at 149 minutes is a coincidence, indicating that the X-ray flare’s periodicity is a harmonic of the radio and gamma-ray periodicities.

“Since the black hole itself emits no radiation, and such regular, repeated periodicity is often a sign of orbital motion, the physical mechanism is likely something orbiting the black hole,” the outlet noted. According to the 2022 study, the object in question is most likely a blob of hot gas bound together by a strong magnetic field that accelerates particles in a synchronic manner while also releasing radiation.

The orbital distance of that blob from the black hole is similar to Mercury’s around the Sun. However, it’s moving at a very fast speed, around 30 per cent the speed of light, with an orbital period of 70 to 8- minutes. According to the astrophysicists, their findings support that interpretation of the radio data, indicating that the gas blob is generating light at several wavelengths.
