Is the Earth s volume expanding, and why is the Earth constantly expanding?

The change is not obvious, not for the time being.

I don't think our planet is getting bigger. First of all, the big ** theory and the expansion theory of the universe are just conjectures. The process by which humans observe and record changes in the universe is only a few hundred years at most.

Observations over these centuries are not enough to determine whether this is true or not. And the big ** theory is just a conjecture, which is opposed by some people. However, since some people say that if the big ** theory is true, and this conjecture is true, then this topic can be discussed for the time being.

If the universe was born from the big **, then, according to human thinking and theory, the universe should be expanding.

Because all ** will generate ** force. This is common knowledge on earth, and this theory has been proven on earth and can be proven by repeated practice. However, no one can be sure if this holds true in the universe.

Moreover, even if the universe is really expanding, the time and speed of the universe expansion will be too slow and too long for humans. If, at this long rate of expansion, a person's lifespan of just a few decades continues to extend with the expansion of the universe, although theoretically possible, it is only a joke.

The universe is expanding rapidly, if it is expanding upwards, downwards, left and right. So, should the planets be farther apart? Then the earth should be farther and farther from the sun every year, and colder and colder every year!

Or is matter growing rapidly, does it mean that the smallest unit of matter, the atom, is starting to grow? So everything has gotten bigger? Because if the state of the atoms does not change, the matter is expanding, and the deformation will become larger.

In fact, by observing different galaxies do keep a distance from each other.

By looking at gravitational redshifts (a phenomenon in which electromagnetic wavelengths become longer and longer, in short, farther and farther away), we find that most of the planets are leaving us. (This is also a strong basis for scientists to believe that the universe is expanding). However, within the same galaxy, or more broadly, within the same group of galaxies, we can also observe many blueshifts (closer distances) due to effects such as gravity.

In fact, in common terms, the expanding tension of the universe is not much different from the gravitational pull between galaxies and celestial bodies. Anyone who studies physics should know about it, so the earth should not get bigger.

Of course yes, the quality is getting worse and worse when it gets bigger like this. It's not a particularly good thing for humans, so the impact is particularly large, and it may lead to uninhabitability.

As far as the current concept is concerned, the earth does not expand with the expansion of the universe, and there is no correlation between the two, and the mass volume of the earth basically does not change.

Although the universe is really expanding, it is only an expansion in space, and the earth is still an unchanging atom after all. Therefore, the Earth does not grow larger as the universe expands.

It's not that it's getting bigger, because there's no real scientific basis to support it, and if the Earth is getting bigger, then it's going to have a certain mass, and it's going to empty the Earth.

The Earth should not be getting bigger, and if it is getting bigger, we can actually feel it on many occasions.

As the movement of the earth's crust slowly disappears, because although it is constantly expanding, the crustal action is also going on at the same time.

The extra land disappears with the movement of the earth's crust. Although the Earth is expanding, the movement of the Earth's crust is also going on.

The volume of the Earth is expanding. In the past, it was thought that the volume of the Earth was 110 billion cubic kilometers. New research by scientists shows that the actual size of the Earth is larger than this number because the Earth is constantly expanding.

Geologists were collecting a lot of data on the east and west sides of the Mid-Atlantic Ridge when they saw something startling: the bottom of the ocean was constantly expanding! As submarine volcanoes continue to pour out lava to form new crust, the old crust on the west side of the ridge is pushed outward, and the eastern seabed of the Atlantic Ocean is moving eastward, and the western seabed is moving westward, and the bottom of the ocean is expanding!

Seafloor expansion led to Wegener's theory of continental drift in 1910. He proposed that all the continents were once united into a supercontinent long ago, and that the supercontinents gradually broke up and separated to form the continents of North America, Greenland, and most of Eurasia, as well as the continents of South America, Africa, Antarctica, and Australia. The current continent is only the uppermost part of several huge plates in the outer layer of our earth, and the boundaries of the plates are areas with violent geological activity, volcanoes, ** occur frequently, and lava swells up from the depths of the earth to form a new crust.

When the two tectonic plates collide, a tall mountain range rises there, and at the same time there is a strong **. As the seafloor expands, affecting the composition of the Earth's interior, the density of the Earth's core gradually decreases, and the Earth's volume grows larger. Due to the increase in volume, the speed at which it rotates is also reduced.

American scientist Wells, who analysed many fossil polyps and learned from the growth rings and growth lines on the hard carapace of this organism that 370 million years ago, a year on Earth was equal to 395 days, but now it is only 365 days. It can be inferred that dinosaurs ruled the world 200 million years ago, when there were 385 days in a year, when the day was only 23 hours. When the first plants left the water to take root on land, about 400 million years ago, there were 405 days in a year, and the day was only 21 5 hours.

The primeval oceans were rich in invertebrates, and vertebrates with protective bones began to be born 600 million years ago, when there were no less than 425 days in a year and a day was only 20 hours long.

This should be another explanation for the daily increase in the time of the earth, and it is believed that in the near future, the secrets of the earth's rotation will be revealed.

The expansion of the universe does not affect the relative positions of celestial bodies in the galaxy. The universe is indeed expanding, but that doesn't change the distance between the Earth and the Sun. It also does not affect the distance between atoms.

The reason for the expansion of the universe is that it is big, and the reason is dark energy. It should not be assumed that this expansion will cause stars to move away from each other in a static space-time structure. In contrast, stars are static relative to the structure of space-time that is expanding on its own.

People often ask, "Where is the center of the expansion of the universe?" "This question only makes sense if all the stars are far away from a certain central point.

Because expansion is the space itself, there is no center.

Martin Reese's book "The Universe" points out that several salient features of the expansion of the universe have been identified. First, while all distant galaxies are moving away from us, the Earth and any point in the universe are not the center of the universe.

On the contrary, everything is far from everything else, without a center. Second, on a local scale, gravity dominates the expansion of the universe and brings matter together. The scale on which this is happening is staggering – even entire clusters of galaxies resist expansion and stay together.

Third, it is a mistake to think that galaxies and clusters of galaxies are "away" from each other in space. A more accurate pictorial depiction is that the space itself carrying the object is expanding.

Imagine an infinite piece of paper with a one-inch square grid drawn on its surface and another infinite piece of paper with a two-inch square grid drawn on it. The second sheet is relative to the first, but without a center. Although the solar system exists in an expanding universe, it does not expand due to the constraints of gravity.

In fact, even galaxies have enough gravity to withstand expansion. Only when you reach a level where mutual gravity is negligible; intergalactic level; The expansion of the universe will become apparent.

Similarly, despite the expansion of the universe, the electrons in the atoms do not disperse. Everything on earth, from your hands to the rulers of the earth, is not expanding. If our rulers expand at the rate at which galaxies are separated, we will never discover the expansion of the universe.

It may make the distance between the sun and the earth larger and larger

It may make the distance between the Earth and the Sun farther and farther away.

It is possible to make the Earth less and less affected by the sun

It will make the earth and the sun appear smaller and smaller.

The Earth is too small for the universe.

I think this will cause these planets to change.

This impact is not very big, is the earth not that big.

I'm afraid that this still needs to be explained by professionals.

This doesn't make much of a difference for us right now.

I think it will squeeze their space to move.
