Why is the universe 13.8 billion years old but 92 billion light years wide?


Looking at the vast universe, we are not only looking at objects that are very far away, but we are also looking at their past. For example, the Sun and Earth are about 150 million km and its light takes about 8 minutes to reach us.

Kong and the world are inextricably linked with what we say about the large-scale structures of the universe. Even so, we have a measure of the so-called LIGHT FIVE, which is about the amount of light that can be seen in the atmosphere in a single year (Approximately 9.5 trillion km).

We use the unit of luminosity because there’s nothing that can be moved around, it’s very convenient and easy to use, especially considering the size of the universe.

Readers have reliably calculated the total number of the universe at about 13.7 billion years. It is strongly suggested that our bets cannot see the universe before it started (before Bang Bang).

Age scale of the universe

The cosmic era begins, light will begin to spread throughout the universe, and if the universe is 13.8 billion years old, light will take 13.8 billion years for light to reach Earth. Accordingly, it would be highly reasonable that the VISible COSTS would be a globe centered on the Earth and with a semi-circle of 13.8 billion light-years.

Depending on the fact that nearly 100 years have passed since Edwan Bell’s death in the early 1920s, scientists have measured the size of the universe, which is actually much larger than that number… 92 billion light years. So why is it so strange?

The answer is very simple, the universe is not static as we think it is, but in fact it is experiencing a very dangerous speed, about 67 km / s per MegaParsec (It is possible that it is 3.3 a.m. the expansion of the strange universe increased by 67km/s).

This title means that at about 46 billion light-years away from Earth, all objects are moving away from Earth at a speed that’s more than AMAZING SPEED, which is the same as Earth. At this point you will never be able to see them simply because the light from them will not be able to take as much as the flower’s expansion rate to reach our eyes.

But guess you have 46 billion years of light, what’s so special about it? That’s right, 46 billion light years x 2 = 92 billion light years, this is also the visible size of the universe.

So what’s out there in the universe?

The mysterious “falling point” in the Universe is considered to be the halfway point between our Universe and another parallel Universe.

But if the Universe is infinite and doesn’t stop expanding in all directions, will the Universes collide at some point? Suddenly, people came up with a new hypothesis: The strange “parallel” universe could “clash into another”.

In the vast Universe (ours), there is a “cold spot” which is widely claimed by the experts to be the collision points of our Universe with the other Universes, based on which people are based. It is hard to believe that there is a multiverse in existence. But don’t get too excited, because this is just a snow, and the other so-called “falling point” is just a guess.

Cold spot

In 1998, the COBE satellite detected that the temperature of the Universe was not uniform. There are regions of hot and cold temperatures (3 Kelvan) but these points are numerous and scattered throughout the universe.

The new satellite called Planck has been launched, it has been able to measure these hot spots with precise accuracy, greatly supporting what the COBE satellite has built. Scientists have read that these points of difference in temperature are remnants of atomic-level wharfs from the Bang Bang to the edge, and it is spreading more and more to the edge. single large area.

These claims sound very reasonable and the facts we do support also support this theory, depending on the difference in temperature points… strange.

There is a special special point and based on its true credit to name it, it is called Cold Spot – Cold Spot.

Around 2008, some authors suggested that this tipping point could very well be the halfway point between the other universes – a point that, if it were to be fixed, the universe would be frozen. Another highlight is like a scratch between a giant object – the universe.

Even if we find hard evidence that the Multiverse exists, even these universes in which we live will no longer be special and unique.

But it’s all just a hypothesis, a strong hypothesis about the existence of cold spots in the universe. We still have other theories that are less frightening simply, although not as interesting, even a bit “cold”.

It is widely speculated that these are just empty spaces in the universe, a vast region with few names and walls. That is also the reason why the “hot spots” are also known as the Great Void. This is the beauty of “we don’t know anything”, we can come up with countless other interesting theories and then gradually, harden and eliminate them one by one.

Either way, none of the suggestions above is absolute. We need more simple facts, to be sure to read that the interesting Multiverse is mundane or at least, refute it so people don’t lose their imagination.

It is also clear that future studies will be very strong for us to know what, but it is also possible, only possible, that the parallel Universes have already solidified, know that we exist.
