Astrophysics first had something to add to the ques­tion of ages with the discovery of thermodynamics in the late 1800s.The gradual contraction of the Sun due to gravity could be a source of energy, replenishing the energy radiated away by sunshine.“How big” is almost always an easier question to answer than “how old.” Though we can measure the sizes of animals and plants easily enough, we can often only guess at their ages. The ancient Greeks Eratosthenes and Aristarchus measured the size of the Earth and Moon, but could not begin to understand how old they were.

And chronometry, very fancy word, but it really is just the science of the passage of time. We assume that we know what happened the last 50 years, the last 100 years.

And now we're starting to assume we know what happened 10,000 years ago, or what happened to our planet 100 million years ago or 1 billion years ago.

You just became the ugliest person on Earth.’” Smirnoff was apparently so turned off by this mysterious guy’s personality that she had to stop watching the show that got cancelled shortly after. "They’ll get a taste, but they won’t get everything.

On the other hand, another “Famously Single” houseguest, David Mcintosh understands perfection will never exist, so he tries to give the women he doesn’t connect with on a romantic level a little love for a certain block of time. I still got to give some love." Speaking of love, "I Love New York" star Tiffany Pollard believes her attention on physical love just might be the issue holding her back from finding her soulmate.

As is known from studies of 400 million year old fossil corals, Earth years were 400 days in duration in distant times because the Earth rotated faster than it does today.

According to calculations based on the fundamental law of rotational motion dynamics involving the moment of inertia of a body, the radius of the ancient Earth 400 million years ago was 553.379 km less than it is today.And so you can look back to that layer of bark just for the half life of carbon-14, and then figure out how much carbon-14 was there in the atmosphere at that period in time. Those are those speleothems that are kind of coming out of the bottom of the cave, or stalactites.And so it's kind of a record of the atmosphere up to 10,000 years. Those are the speleothems that are coming from the top of the cave."Every woman you meet is not going to be an amazing woman. "I have, but if the d-ck is good, I’ll put up with it. In the last video, we talked about the idea that if I dug up a bone someplace, if I dug up a bone, and if I were to measure its carbon-14, and I found that it had half of the carbon-14 that I would expect to find in a living animal or plant, that I said, hey, maybe one half life has gone by, or roughly for carbon-14, one half life is 5,730 years.More generally, uniformitarianism holds that the physical laws and processes we see today are the key to understanding the past.
