“idea here is not to go, ‘Yeah, look at me. I’m in space.’” Instead, he said that “the prince is missing the point. The point is these are the baby steps to show people [that] it’s very practical. You can send somebody like me up into space.” — William Shatner

William Shatner may be famous for his fictional otherworldly travels thanks to his role in the “Star Trek” universe, however, on October 13 he took a real-life trip that took him to space.

Along with three other passengers, the actor nabbed a spot on Jeff Bezos’ Blue Origin space capsule, which headed out for a flight that lasted for 11 minutes, according to CNN. While it was obviously an incredible experience for the star, not everyone was impressed.

We used to think the Big Bang meant the universe began from a singularity. Nearly 100 years later, we’re not so sure.

For example, the end could come as “heat death” (a reverse of the Big Bang known as the Big Crunch) or The Big Rip (when dark energy becomes so powerful it tears everything we know to pieces). But another possibility that has gained traction is the Cosmic Death Bubble.

The details of this death by bubble are pretty complicated, but it’s based on the idea that the universe is metastable, which means it’s not in its lowest or most stable energy state. While we’re okay for now, there’s the (remote) possibility that the universe could drop into a lower energy state, which would set off a giant light-speed bubble that destroys everything it touches.

Now, as Erik Vance at LiveScience reports, researchers have calculated how long before this Cosmic Death Bubble comes for us, if it happens at all.

Researchers propose quantum circuit black hole lasers to explore Hawking radiation.

Given the tricks GPT-3 had up its sleeve, it’s intriguing to wonder how the Megatron-Turing model may surprise us given that it’s three times larger.

Scientists are getting closer to being able to spot Hawking radiation – that elusive thermal radiation thought to be produced by a black hole’s event horizon. Just understanding the concept of this radiation is tricky though, let alone finding it.

A new proposal suggests creating a special kind of quantum circuit to act as a ‘black hole laser’, essentially simulating some of the properties of a black hole. As with previous studies, the idea is that experts can observe and study Hawking radiation without actually having to look at any real black holes.

The basic principle is relatively straightforward. Black holes are objects that warp spacetime so much, not even a wave of light can escape. Swap spacetime for some other material (such as water) and make it flow quickly enough so that waves passing through are too slow to escape, and you’ve got yourself a fairly rudimentary model.

Astronomers have discovered unusual signals coming from the direction of the Milky Way’s center. The radio waves fit no currently understood pattern of variable radio source and could suggest a new class of stellar object.

“The strangest property of this new signal is that it is has a very high polarization. This means its light oscillates in only one direction, but that direction rotates with time,” said Ziteng Wang, lead author of the new study and a Ph.D. student in the School of Physics at the University of Sydney.

“The brightness of the object also varies dramatically, by a factor of 100 and the signal switches on and off apparently at random. We’ve never seen anything like it.”

Whether these different organisations want to land astronauts, install a human outpost or mine minerals and make rocket fuel on the moon, it still lacks an exceptional and important asset– A lunar radio Telescope. Why? Because this development will be uniquely poised to answer one of humanity’s greatest questions: What is our cosmic origin?

All the lunar missions that are being planned along with all other missions that different organizations want to accomplish, will be of no use if we don’t seek answers to fundamental questions like “what is the universe made up of? What are we made up of?” And a telescope on the far side of the moon will help us answer these important questions!! So let’s take a look at why this is important and what NASA is planning to do about it.
As mentioned earlier the universe constantly beams its history to us. For instance, the information of what happened long ago in the universe is contained in the long length radio waves that are present everywhere throughout the universe and most likely hold the details about how the first black holes and stars were formed. But there’s a problem. Our noisy radio signals and our atmosphere block these signals from coming to the earth and we can’t read them. The far side of the moon is the best place in the inner solar system to monitor these low-frequency radio waves and help us in detecting certain faint ‘fingerprints’ that the big bang left on the cosmos. The problem with our earth bound telescopes is that they encounter too much interference for electromagnetic pollution caused by human activity, whether it is short-wave broadcasting or maritime communication. On the top of that our ionosphere blocks the longest wavelengths from reaching our earth-based telescopes in the first place. We need these signals to understand and learn whether our universe inflated rapidly in the first trillionth of a trillionth of second after the big bang.

This is the reason why NASA is in the early stages of planning what it would take to build an automated research telescope on the dark side of the moon. One of the most ambitious proposals is to build the Lunar Crater radio telescope or the LCRT

A new study showing how the explosion of a stripped massive star in a supernova can lead to the formation of a heavy neutron star or a light black hole resolves one of the most challenging puzzles to emerge from the detection of neutron star mergers by the gravitational wave observatories LIGO and Virgo.

The first detection of gravitational waves by the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) in 2017 was a neutron star merger that mostly conformed to the expectations of astrophysicists. But the second detection, in 2,019 was a merger of two neutron stars whose combined mass was unexpectedly large.

“It was so shocking that we had to start thinking about how to create a heavy neutron star without making it a pulsar,” said Enrico Ramirez-Ruiz, professor of astronomy and astrophysics at UC Santa Cruz.

In a rare non-magnetic kagome material, a topological metal cools into a superconductor through a sequence of novel charge density waves. Researchers have discovered a complex landscape of electronic states that can co-exist on a kagome lattice, resembling those in high-temperature superconductor.

The Computational Cosmology group of the Department of Astronomy and Astrophysics (DAA) of Valencia University (UV) has published an article in The Astrophysical Journal Letters, one of the international journals with the greatest impact in Astrophysics, which shows, with complex theoretical-computational models, that cosmic voids are constantly replenished with external matter.
