How did scientists use to know the They are produced when massive objects like black holes Hubble constant?or neutron (中 ) stars smash together. A. By spotting gravitational waves in To calculate the Hubble constant (常 ), which space-time.quantifies the expansion rate of the universe, ...
Neutron stars can have a resounding impact around the universe. Scientists recently announced the first detection ofgravitational wavescreated by twoneutron starssmashing into each other. 1:33 Gravitational Waves 101What are gravitational waves and how are they detected? These ripples in space-time, ...

But in fact, both stars are pulling you towards them. And you’re pulling back, connected across trillions of kilometers by gravity. Gravity is the attractive force between two objects with mass – any two objects ...
The10 detections made so far are too few to provide a preciseestimate of the constant. Perhaps this is the way science has togo : long and hard.32.What is Paragraph 2 mainly about?A. The definition of gravitational waves.B. The definition of black holes or neutron stars.C. Things that...
If we press hard enough, the protons and neutrons will burst apart into what they're made of: smaller particles called quarks. We'll then have a mess of quarks -- the type of quarks called "up" and "down," which have certain masses and are the only kinds found in matter on Earth....
Because stars are so massive and made out of gas clouds, their own intense gravity is always trying to collapse them. The fusion reactions happening in the core are like a giant fusion bomb that is trying to explode the star. The balance between the gravitational forces and the explosive ...

"We are made of star-stuff." Krauss agreed, stating that "every atom in your body was once inside a star that exploded...The atoms in your left hand probably came from a different star than in your right hand, because 200 million stars have exploded to make up the atoms in your body...
"Sweet Dreams (Are Made of This)" turned 40 last year. What are you really proud of now, when it comes to that song? As soon as it comes on the radio, over a sound system at a festival or anywhere, there’s an instant reaction from the crowd or the listener. Sonically, the bass...
