More than 100 years ago, a famous scientist named Albert Einstein came up with an idea about how time works. He called it relativity. This theory says that time and space are linked together. Einstein also said our universe has a speed limit: nothing can travel faster than the speed of light (186,000 miles per second).
Until recently, astronomers estimated that the Big Bang occurred between 12 and 14 billion years ago. To put this in perspective, the Solar System is thought to be 4.5 billion years old and humans have existed as a genus for only a few million years. Astronomers estimate the age of the universe in two ways: 1) by looking for the oldest stars
Mass: 925,335 pounds (419,725 kilograms) Habitable Volume: 13,696 cubic feet (388 cubic meters) not including visiting vehicles. Pressurized Volume: 35,491 cubic feet (1,005 cubic meters) Power Generation: 8 solar arrays provide 75 to 90 kilowatts of power. Lines of Computer Code: approximately 1.5 million.A NASA mission called Gravity Probe B A more logical approach might be to consider the 'Big Bang' theory from a pre-existing fabric of space-time without any real matter, as a proposed one Dan Levitt's book, "What's Gotten Into You," evokes a series of striking and often forceful images in tracing how our cells, elements, atoms and subatomic particles all found their way to Dark matter is stuff in space that has gravity, but it is unlike anything scientists have ever seen before. Together, dark matter and dark energy make up 95% of the universe. That only leaves a small 5% for all the matter and energy we know and understand. This might be a surprise, but we don't know what most of the universe is made of.eCm8nR.
