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.
We knew the Chicxulub crater was massive. We just didn't know how widespread the damage actually was.
- The asteroid that crashed into the Yucatan caused a mile-high tsunami.
- The wave was 52 times higher and 2,600 times more energetic than the 2004 Indian Ocean tsunami that killed over 227,000 people.
- Sediment was disturbed 3,700 miles from the site of the crash.
Between Carl Sagan's laughter, the brainwaves of somebody in love, and a live theremin concert, humanity has sent a lot of data out into the stars.
- Ever since we've had the capability, humanity has been desperately trying to make contact with other life in the universe.
- While we've been beaming out information passively through our television and radio broadcasts, we've also sent more intentional messages.
- Looking at these messages tells us how humanity wants to think of itself and what kind of relationship we hope to have with alien life.
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.
