Was the universe made for us?

Posted by in categories: alien life, chemistry, physics

Check out the physics courses that I mentioned (many of which are free!) and support this channel by going to https://brilliant.org/Sabine/ where you can create your Brilliant account. The first 200 will get 20% off the annual premium subscription.

In this video I explain how the argument that the universe is finetuned for life works, why it’s wrong, how the mistake happens, and what that means for the existence of god and the multiverse.

Does the Past Still Exist?

To try out our new course (and many others on math and science), go to https://brilliant.org/sabine. You can get started for free, and the first 200 will get 20% off the annual premium subscription.

Albert Einstein taught us that space and time belong together to a common entity: space-time. This means that time becomes a dimension, similar to space, and has profound consequences for the nature of time. Most importantly it leads to what has been called the block universe, a universe in which all moments of time exist the same way together. The future, the present, and the past are the same, it is just our perception that suggests otherwise.

Scientists Unravel “Hall Effect” Physics Mystery

Posted by in categories: computing, physics

A multinational group of scientists has made progress in the use of antiferromagnetic materials in memory storage devices.

Antiferromagnets are materials with an internal magnetic field induced by electron spin but virtually no external magnetic field. Since there is no external (or “long-range”) magnetic field, the data units, or bits, may be packed more densely inside the material, making them potentially useful for data storage.

The ferromagnets commonly utilized in typical magnetic memory devices are the opposite. These devices do have long-range magnetic fields produced by the bits that prevent them from being packed too tightly together since otherwise they would interact.

Physicists develop a linear response theory for open systems having exceptional points

Posted by in categories: energy, engineering, physics

Linear analysis plays a central role in science and engineering. Even when dealing with nonlinear systems, understanding the linear response is often crucial for gaining insight into the underlying complex dynamics. In recent years, there has been a great interest in studying open systems that exchange energy with a surrounding reservoir. In particular, it has been demonstrated that open systems whose spectra exhibit non-Hermitian singularities called exceptional points can demonstrate a host of intriguing effects with potential applications in building new lasers and sensors.

At an exceptional point, two or modes become exactly identical. To better understand this, let us consider how drums produce sound. The membrane of the drum is fixed along its perimeter but free to vibrate in the middle.

As a result, the membrane can move in different ways, each of which is called a mode and exhibits a different sound frequency. When two different modes oscillate at the same frequency, they are called degenerate. Exceptional points are very peculiar degeneracies in the sense that not only the frequencies of the modes are identical but also the oscillations themselves. These points can exist only in open, non-Hermitian systems with no analog in closed, Hermitian systems.

The Nobel prize in physics this year went to black holes. Generally speaking. Specifically, it was shared by the astronomers who revealed to us the Milky Way’s central black hole and by Roger Penrose, who proved that in general relativity, every black hole contains a place of infinite gravity — a singularity. But the true impact of Penrose’s singularity theorem would is much deeper — it leads us to the limits Einstein’s great theory and to the origin of the universe.

Physicists Broke The Speed of Light With Pulses Inside Hot Plasma

Posted by in categories: law, physics

Most of us grow up familiar with the prevailing law that limits how quickly information can travel through empty space: the speed of light, which tops out at 300,000 kilometers (186,000 miles) per second.

While photons themselves are unlikely to ever break this speed limit, there are features of light which don’t play by the same rules.

Manipulating them won’t hasten our ability to travel to the stars, but they could help us clear the way to a whole new class of laser technology.
