The Center of the Milky Way Might Not Be a Black Hole After All
The center of the Milky Way could be dark matter instead of a supermassive black hole, according to a new study.
The study is based on observations of the objects that orbit closest to the center.
If it’s true, this could help explain how supermassive black holes originate.
Earth tipped over on its side and back between 79 million and 86 million years ago, a study shows.
The planet tilted by 12 degrees - which would've moved New York City to where Florida is right now.
Earth's crust can shift like this depending on how weight is distributed across planet's surface.
One space rock hit Mexico 66 million years ago, causing a mass extinction that doomed the dinosaurs.
A study suggests another asteroid struck Ukraine 650,000 years later, possibly warming the climate.
These back-to-back impacts may have delayed Earth's recovery from the mass extinction.
Nuclear fusion company General Fusion is building a demonstration facility in the UK.
Jeff Bezos has been an investor in General Fusion for over a decade.
The new facility will begin construction next year, and should be operational by 2025.
Dogs are being trained to detect COVID-19 in Thailand, France, Britain, Chile, Australia, Belgium, Germany, and other countries, and preliminary studies "suggest that their detection rate may surpass that of the rapid antigen testing often used in airports and other public places," The New York Times reports. Cells infected with COVID-19 have a specific scent that dogs can sniff out in seconds, even if the person doesn't have symptoms.
