On April 23, 1992, a scientific team led by astrophysicist George Smoot announced that it had found the primordial "seeds" from which the universe has grown. They analyzed data gathered by NASA's Cosmic Background Explorer satellite and discovered the oldest known objects in the universe—so called "wrinkles" in time—thus finding a long-anticipated missing piece in the Big Bang model.
GRB 090423 was a gamma-ray burst (GRB) detected by the Swift Gamma-Ray Burst Mission on April 23, 2009, at 07:55:19 UTC whose afterglow was detected in the infrared and enabled astronomers to determine that its redshift is z = 8.2, making it one of the most distant objects detected at that time with a spectroscopic redshift (GN-z11, discovered ...
The following is a list of the world's oldest surviving physical documents. Each entry is the most ancient of each language or civilization. For example, the Narmer Palette may be the most ancient from Egypt, but there are many other surviving written documents from Egypt later than the Narmer Palette but still more ancient than the Missal of Silos.
Since the universe must be at least as old as the oldest things in it, there are a number of observations that put a lower limit on the age of the universe; [15] [16] these include the temperature of the coolest white dwarfs, which gradually cool as they age, and
No longer scattered by free electrons, the photons were ("decoupled") and propagated freely. This vast collection of photons from the earliest times of the universe can still be detected today as the cosmic microwave background (CMB). [5]: 22.4.3 This is the oldest direct observation we currently have of the universe.
2650 BC: The oldest extant record of a unit of length, the cubit-rod ruler, is from Nippur. 2600 BC: The oldest attested evidence for the existence of units of weight, and weighing scales date to the Fourth Dynasty of Egypt, with Deben (unit) balance weights, excavated from the reign of Sneferu, though earlier usage has been proposed.

The world’s oldest wine has been discovered at a Roman burial site in Spain, and one thing is clear — it definitely had body. For roughly 2,000 years, ...
The earliest evidence of humans using fibers is the discovery of wool and dyed flax fibers found in a prehistoric cave in the Republic of Georgia that date back to 36,000 BP. [5] [6] Natural fibers can be used for high-tech applications, such as composite parts for automobiles and medical supplies.
