Cosmologists propose a groundbreaking model of the universe using string theory.
- A new paper uses string theory to propose a new model of the universe.
- The researchers think our universe may be riding a bubble expanded by dark energy.
- All matter in the universe may exist in strings that reach into another dimension.
It has already found several bizarre planets outside of our solar system.
- The Kepler program closed down in August, 2018, after nine and a half years of observing the universe.
- Picking up where it left off, the Transiting Exoplanet Survey Satellite (TESS) has already found eight planets, three of which scientists are very excited about, and six supernovae.
- In many ways, TESS is already outperforming Kepler, and researchers expect it to find more than 20,000 exoplanets over its lifespan.
The end of the world is the main focus of his new book.
- Everybody from Elon Musk to Stephen Hawking has said we should colonize a 'Planet B' due to the threat to our existence. Martin Brees, the UK's Astronomer Royal, has another perspective on it.
- "I think we have to accept that there's no planet B, which can ever be made as comfortable as the Earth," he recently told The Current's Anna Maria Tremonti.
- In a time of ever-worsening climate change that threatens the very existence of human beings, his focus is on maintaining and fixing the planet we now live on, but still with an eye toward the stars.
That disastrous rock may now looks to have been a Beta Taurid passenger
- Analysis of the Tunguska tree-fall patters suggests a familiar source for the asteroid that caused it
- Its timing also fits perfectly with a late June annual meteor shower
- Nonetheless, it's more interesting than dangerous. Put down that helmet.
NASA's Michelle Thaller explains how an accidental discovery led to the 1978 Nobel Prize in Physics.
- In 1964, two American radio astronomers, Arno Penzias and Robert Wilson, discovered the Cosmic Microwave Background by accident. Their resulting work earned them the Nobel Prize in Physics in 1978.
- They had long been trying to get rid of the annoying "noise" in their data (even thinking it was all the pigeon poop in their telescope) only to realize the noise was the treasure. They had stumbled upon the oldest light in the universe, and some of the strongest evidence to support the Big Bang theory. (What is the Cosmic Microwave Background?)
- That's why space and science are never boring, explains NASA astronomer Michelle Thaller. One scientist's junk data can be another's Nobel Prize.
