2021-05-18 03:47:19 A black hole permanently scrambles information that can’t be recovered with any quantum machine learning algorithm, shedding new light on the classic Hayden-Preskill thought experiment. A new theorem from the field of quantum machine learning has poked a major hole in the accepted understanding about information scrambling. This theorem implies that we are not going to be able to use quantum machine learning to learn typical random or chaotic processes, such as black holes. In this sense, it places a fundamental limit on the learnability of unknown processes. Open / Comment

2021-05-17 19:19:41 The Four Fundamental Forces of Nature:-

1. Gravitational Force –

Weakest force but has infinite range. (Not part of the standard model). Gravitational force acts between any two pieces of matter in the Universe since mass is its source.

2. Weak Nuclear Force –

Next weakest but short range.The weak nuclear force is responsible for radioactive decay and neutrino interactions.

3. Electromagnetic Force – Stronger, with infinite range.

The electromagnetic force causes electric and magnetic effects such as the repulsion between like electrical charges or the interaction of bar magnets.

4. Strong Nuclear Force –

Strongest but short range.
The Strong Nuclear Force is responsible for holding the nuclei of atoms together. Open / Comment

2021-05-17 19:09:38 This spring, astronomers at Leiden University announced a giant gas exoplanet called YSES 2b, orbiting much farther out from its star than has typically been seen before. It is 20 times as far from its star as Jupiter is from our sun. That’s the equivalent of 110 times the distance from Earth to the sun! Open / Comment

2021-05-17 09:25:10 Is our Milky Way Galaxy thin?

Magnificent spiral galaxy NGC 4565 is viewed edge-on from planet Earth. Also known as the Needle Galaxy for its narrow profile, bright NGC 4565 is a stop on many telescopic tours of the northern sky, in the faint but well-groomed constellation Coma Berenices. This sharp, colorful image reveals the spiral galaxy's boxy, bulging central core cut by obscuring dust lanes that lace NGC 4565's thin galactic plane. An assortment of other background galaxies is included in the pretty field of view. Thought similar in shape to our own Milky Way Galaxy, NGC 4565 lies about 40 million light-years distant and spans some 100,000 light-years. Easily spotted with small telescopes, sky enthusiasts consider NGC 4565 to be a prominent celestial masterpiece Messier missed. Open / Comment
