我们所在的银河系,在宇宙中的地位如何?

   我们所在的银河系,在宇宙中的地位可以说微不足道,但是银河系在我们人类的世界中,却是独一无二的。

    每当我们仰望星空时,会看到一条暗明相间的银河,这其实就是我们银河系的一部分;因为我们太阳系处于银河系之中,所以夜晚看到的这条银河,实际上是银河系的切面。


    银河系内有数千亿颗恒星,我们太阳只是其中一颗,而我们的银河系,在可观测宇宙中又是微不足道的;据天文学家估计,在我们可观测宇宙中,有超过1万亿个星系,我们银河系只是其中一个而已。

    从可观测宇宙出发,首先看到的是宇宙大尺度网状结构,就如一张渔网一般,网中每根亮线都由千千万万个超星系团组成,每个超星系团又由许多次级星系团或者星系群组成。


    我们逐步放大后得到图Ι,图Ι中可以勉强看到银河系发出的光,继续放大就可以看清我们银河系了;我们还可以看到,银河系只不过是千千万万个星系中毫不起眼的一个,没有特别之处。


如果用尺度来比较,我们银河系直径大约20万光年,可观测宇宙直径大约930亿光年;如果把银河系比作乒乓球,那么可观测宇宙直径有35公里,我们地球和一个氢原子核差不多大小。

    所以,我们银河系在宇宙中的地位,是微不足道的;不过银河系还是太大了,旅行者一号探测器以17km/s的速度,穿越整个银河系需要4亿年呢!


但是对我们人类世界来说,银河系却是独一无二的,人类曾经在数百万年的时间里,夜晚仰望星空时,看到的一切,几乎都是银河系内的事物。

探测器拍到火星地表神秘照片,科学家兴奋道:希望这一切是真的


人类一度把火星看作是地球的“替代者”,因为在还没有对它进行深入探索之前,单从火星的表面和外部条件来看,它和地球有着许多相似的地方,例如两者都位于太阳系的宜居带中。在对金星失去兴趣之后,科学家们把目标转向了火星,并且在上个世纪末就开始陆续向火星发射探测器。然而在第一架火星探测器登上火星之后,它给人类带来的并不是好消息。


原来火星上的自然环境并没有人类想象中那么美好,为了进一步探测清楚火星的环境,美国宇航局又陆续发射了多架火星车,但几乎所有火星车的探测结果都是一致的,并没有在火星地表发现水资源、生命和大气层。正当公众为火星的真实面貌感到失望的时候,太空外传输回来的一张照片再次引起了公众对火星的兴趣,因为这张照片中的火星地表上出现了酷似“人脸”的现象。


据悉这张照片是美国的“海盗号”探测器拍摄的,除了诡异的“人脸”之外它还拍摄到火星的地表存在酷似金字塔的“建筑物”。从照片上来看,这座“火星金字塔”矗立在倾斜的火星山上,它的外形轮廓十分规则,和埃及金字塔十分相似。不仅如此,科学家通过放大照片还发现了金字塔的周围还存在一条条的道路,这些道路的分布井条有序,不禁让人怀疑火星上是否存在着外星文明呢?


对于地球上的埃及金字塔,人类至今还没有弄清楚古埃及人是如何建立起如此恢弘的建筑的,而且在荒芜的非洲沙漠中一建就是几十座。考古专家表示,以古埃及人的生产劳动水平和科技水平,是无法建造如此壮观的建筑的,但又无法找到其他的证据来证明它不是人类建造的。甚至有观点认为,或许金字塔就不是人类自己建造的,可能是外星文明造访地球之后帮助埃及人建造的,当然这只是多种未被证实的说法中的一种。


火星地表一下子出现了两种神秘现象,难道它们之间存在某种联系吗?科学家带着这样的疑问将火星“人脸”照片和狮身人面像进行对比,结果发现两者的轮廓是相似的。这是否说明了地球上的金字塔和火星上的“金字塔”都是同一个文明建造的呢?科学家也希望如此,这样问题就变得简单了。


但是后来美国宇航局证实了照片中的“人脸”只是火星地表一座山丘的影子而已,人们之所以将其联想成了人脸,或许是因为人类的潜意识认为火星存在着外星生命。除了“人脸”照片之外,很多神秘的火星照最后都被证实是太阳光照射在火星上形成的阴影。这确实能够解释为什么人类一直没有在火星上找到生命的痕迹,但却一直拍摄到疑似生命的照片。


尽管如此,科学家们还是没有放弃对火星的探究。不仅如此,一些商业的航天公司声称将在未来几年内登陆火星,大家拭目以待吧。

Barbell boating, the 5 most common mistakes

Barbell rowing is one of the best practice back exercises in history, and it is also the most error-prone action. Why? There are indeed a lot of people who do barbell rowing, but there are many people who have been habitually wrongly trained to see the following five mistakes.


Mistake 1: Knee bending

As an upper-body training, this does not mean that the position of the knee is not important. Too deep, the hips are too low, making it harder to keep your body in motion. On the other hand, if you lock your knees, you put unnecessary pressure on the lower back and limit the weight you can use.

A reasonable knee bending angle should be 15-20 degrees, and this angle should not change throughout the stroke.


Mistake 2: Standing on a stool

This phenomenon is less common. But there are still some people who try to stand on the bench and finish the barbell rowing.

There are many reasons to refute this action. Even if it has a benefit, the probability of you falling from the stool at great weight is also high. The best position for the barbell at the start should be that the upper body is slightly above the level and the hands are straight.

If you choose to drop a little more, your lower back is in a vulnerable position, and it is also in a position where it is not mechanically strong. The action does the whole process, not the extension of other parts.



Mistake 3: Bow the lower back

This is already very common. To avoid back injuries, you need to keep your lower back in a neutral position. The back of the bow will squeeze your disc. The bow back is never recommended, and it doesn't make sense to do it for maximum weight. There is a small way to help you, that is to lift your chest, not the entire torso.



Mistake 4: Lift the upper body when pulling up

Hard pull and high turn are good moves, but don't mistake the barbell rowing and mix them up. At the same time doing boating and lifting the torso at the same time, this is the performance of the weight is too heavy. The role of the lower back muscles in this movement is to maintain the position of the spine, not the target muscle.

At the same time, this also shortens the travel of the action. The angle of each rowing is different. What do you use to track the progress of your strength? That's right, a lot of big guys will sway that one, but remember, just at the end of the group, lifting the torso can make this movement easier, but the simpler it means the less progress you make.

How long have you been cheated by fitness?(Problems that are always encountered in fitness)

How long have you been cheated by fitness?


Fitness always encounters many problems

Many people are asking, but the answer always is various.

For example, "running will cause the thick legs"

"protein powder hurts the body"

"The more you sweat, the more effective you are."

......

How many fitness rumours have you trusted?


Rumour 1 running will cause the thick legs


Correct:

Many people find that their legs become thicker after running. This is because the muscles in the legs are congested after running, causing muscle swelling, but they will slowly recover as long as they are fully rested. Growing muscles is much slower than losing fat.


Rumour 2 Girls do strength training will become "King Kong Barbie"


Correct:

Muscle growth requires a lot of training plus a regular diet and rest. For girls is not easy to get muscle. The normal maximum muscle growth is about 0.23 kg/month. According to the training volume and diet of the general fitness person, it is still difficult to practice the "King Kong Barbie". Moreover, the muscles that are trained are not used. , will also be consumed.


Rumour 3 The faster the metabolism, the shorter the life expectancy

Many people take animals for example. For example, turtles live longer because they walk slowly and consume less.


Correct:

long-term exercise is effective in preventing ageing. If you train for a long time, then when you have a certain age, you will have enough strength to support you to exercise, such as running, swimming, climbing, etc. And long-term endurance training will delay the ageing of the cardiovascular system and respiratory system. It has been proven that exercise can not only balance the body's metabolism, but also prevent the decline of bodily functions.


Rumours 4 The more sweat during your exercise, the more effective it is to reduce fat.

Many people think that sweating is a phenomenon in which fat is burned and fat is excreted from the body.


Correct:

The essence of fat loss is calorie consumption > intake of calories. As long as you are exercising, you are experiencing calorie expenditure and have little to do with sweating. And sweating is related to personal physique. Some people just sweat when they start exercising, and some people are not soaked after exercising. If you sweat too much during exercise, you should replenish your water in time to prevent excessive loss of water and electrolytes.


Rumours 5 Muscle men are eating protein powder / eat protein powder is harmful to the body


correct:

Protein powder is just a convenient supplement to protein. The source of protein is not only protein powder but also pork, beef, fish, beans and other foods. The amount of protein supplementation is related to the strength of the training. Generally, the training intensity is large, or the amount of protein supplement in the diet is not enough, and the protein powder is selected as a supplement.

Protein powder is not a hormone, nor is it a muscle-enhancing medicine. Only when the training reaches a certain level, the muscle's demand for protein increases. At this time, the protein powder will have a role. Therefore, even if you eat protein powder, your muscles will not grow if you don't exercise.


Rumours 6 the people who have abdominal muscles the power is greater than that of people without abdominal muscles.


correct:

Everyone has abdomen, but the apparent degree of the abdominal muscles is related to the body's body fat rate. Abdominal muscles are not obvious and do not mean that the waist and abdomen strength will be poor, but only wrapped in fat. If the abdominal muscle line is not obvious enough, you can first consider the training from the fat reduction.


Rumours 7The greater the weight during training, the more effective

correct:


When training, be sure to pay attention to the standard of movement and the correct force of the muscles so that the muscles can be stimulated correctly so that the training effect can be more efficient. On the contrary, if you focus on the strength of training, each training uses the ultimate weight or exceeds the limit weight, which will lead to the regulation of the action, not to achieve the effect, but will also hurt the muscle.

Therefore, in the training, first, use the lightweight to regulate the movement, find the correct force point of the muscle, slowly and gradually, repeat many times, can also stimulate the muscle.


Rumours 8 Muscle soreness after exercise shows that this exercise has an effect


correct:

There are many reasons for muscle soreness. For example, there may be excessive training, it may be a training movement error, or it may be caused by a lack of training for a long time and a decline in training level. Therefore, whether the muscles are sore on the second day after exercise does not have much to do with exercise.
