L’Univers, l’infime et l’infini

Ce que l’on voit actuellement, ce ne sont pas des étoiles mais des milliers de galaxies.

Depuis toujours, l’être humain sait qu’il tient une place spéciale dans l’univers. Centre du monde, joyau de l’évolution il a levé les yeux vers le ciel . Et puis, il s’est mis à explorer.  Lhomme a découvert qu’il habitait une planète parmi d’autres dans le système solaire, un petit point bleu en rotation autour de son étoile.

L’univers foisonne d’astres plus notables que le soleil, étincelle anonyme au pied des hiérarchies stellaires.

Une planète finalement de taille banale, orbitant autour d’une étoile plutôt blême, que les humais ont même classée comme une naine jaune. Une taille ridicule à côtes des très nombreuses géantes et super géantes.

Prenez la grandiose Eta carinais par exemple, une étoile un million de fois plus lumineuse que le soleil., Ou bien la majestueuse Uy scuti 5 milliards de fois plus volumineuse.

Pour mesurer les distances immenses entre ces étoiles, l’homme a dû inventer une unité de longueur spéciale, celle parcourue pendant un an par une particule de lumière, 10 000 milliards de kilomètres .Une année lumière est donc à un kilomètre, ce qu’un kilomètre est à la taille d’un virus .Et l’univers mesure 80 milliards d’années-lumière.

Les étoiles sont incroyablement nombreuses. Une seule galaxie contient entre 100 et 400 milliards d’étoiles. ET les galaxies elles mêmes sont innombrables. Ce que l’on voit actuellement, ce ne sont pas des étoiles mais des milliers de galaxies. Pour l’ensemble de l’univers visible, cela représente au total 400 sextillions d’étoiles. Un nombre tellement important que l’être humais peine à le concevoir. Pourtant ce n’est pas si dur : il y a autant d’étoiles dans l’univers observables que de gouttes d’eau dans tous  les océans de sa planète Terre, ou de grains de sable sur toutes ses plages et ses déserts. Mais cette immensité ne représente elle-même que l’univers observable, cette zone au delà de laquelle les télescopes humains ne peuvent voir, une toute petite partie de l’univers réel.

L’Homme habite la banlieue lointaine d’une galaxie anodine, perdue dans un univers si vaste qu’il ne peut même pas le concevoir dans son ensemble.

Face à ces échelles astronomiques, ne serait-il pas… insignifiant ?

Elon Musk is already no longer the richest man in the world

Elon Musk is already no longer the richest man in the world

Tesla boss is ironed behind Jeff Bezos, but it might not last

Last weekend, Elon Musk touched the stars by becoming the richest man in the world  with a fortune then estimated at 188.5 billion dollars. But here he is already back on the second step of the podium while Tesla’s stock price dropped slightly on Monday. An 8% drop in value which saw the entrepreneur’s portfolio shrink by $ 13.5 billion.

Therefore, Jeff Bezos  recovered his first place. However, the gap between the boss of Amazon, dethroned for the first time since 2017, and Elon Musk is slim. Indeed, Jeff Bezos exceeds his main competitor by only a trifle of $ 6 billion while the shares of the e-commerce giant also experienced a slight decline at the start of the week. In fact, the scales could tip again in the side of the boss of Tesla in a short time.

Tight podium

If Elon Musk saw his fortune explode in 2020 – an additional $ 150 billion since March according to Forbes , it is obviously thanks to the stock market success of Tesla and SpaceX.

The value of the self-driving car company has jumped 720% in the space of a year and is now worth more than Facebook . Stratospheric figures which recently led the board of directors of the firm to offer its founder a few million additional shares whose cumulative value exceeds $ 6 billion if we rely on last Monday’s prices. An operation which, if it has yet to be validated by the financial authorities, could allow Elon Musk to return to Jeff Bezos.

How did Elon Musk become the richest man in the world?

The boss of Tesla has just dethroned Jeff Bezos, the creator of Amazon, thanks to the soaring price of the stock market.

He had gradually climbed the stairs, then joined the top 3 of the greatest fortunes in the world in September 2020. The year 2021 looks promising for Elon Musk who has become  the richest man in the world , according to the Bloomberg agency which maintains a ranking of billionaires.

Amazon boss Jeff Bezos is no longer number 1 . The one who holds the title of the richest man on the planet since 2017, ahead of Bill Gates (Microsoft), Bernard Arnault (LVMH) and Mark Zuckerberg (Facebook), has just been caught by the whimsical entrepreneur of 49 years, Elon Musk.

This meteoric rise is explained by the surge in Tesla securities on  Wall Street , in which Elon Musk holds an 18% stake . Tesla stock has seen its value more than 7-fold in 2020. This then allows  Elon Musk  to hold a fortune of 188.5 billion dollars . That of the creator of Amazon, it amounts to 1.5 billion.
Remarkably, Elon Musk refuses his minimum wage of $ 56,000 each year at Tesla. In January 2018, the company announced that it would pay Elon Musk nothing for the next ten years: no salary, no bonus, no shares. 

Rich even richer despite the crisis

The coronavirus pandemic is an economic disaster for most Americans , but not for Elon Musk. Many  billionaires  got richer during the pandemic, but no one earned as much as him. The CEO of Telsa earned more than $ 48 billion between March 18 and August 13, 2020, an increase in his fortune of more than 197% , according to a new analysis by the think tank, the Institute for Policy Studies .

But that’s not all, Elon Musk’s wealth should continue to grow in the months to come. And, thank you  Joe Biden  ? Stock market action has been boosted by the election of Joe Biden, who promises to promote the development of electric vehicles  in the United States. The group’s stock is expected to be included in many financial products systematically, which should give Elon Musk even more weight.

Tesla founder Elon Musk becomes richest man in the world

With the surge in Tesla’s securities on the stock market, of which he holds 18%, the whimsical 49-year-old entrepreneur has passed Jeff Bezos, the boss of Amazon.

Elon Musk, the boss of high-end electric vehicle maker Tesla, rose to the rank of the richest man in the world on Thursday (January 7) thanks to the soaring stock market shares, according to Bloomberg News calculations .

With Tesla’s stock market soaring , in which he owns 18%, the whimsical 49-year-old entrepreneur, who also runs SpaceX, passed Jeff Bezos, the Amazon boss who held the title of richest man in the planet since 2017.

While Tesla stock, which saw its value more than 7-fold in 2020 and still rose sharply on Wall Street on Thursday, the South African-born engineer’s fortune hit $ 188.5 billion soon after. the opening of the session, exceeding that of Jeff Bezos by 1.5 billion.

The enthusiasm of investors

The day before, Tesla broke the $ 700 billion mark for the first time at the close as the stock finished up almost 3% to $ 755.98. Thursday morning, the action was close to $ 800 climbing 5.7%.

The group’s sales, however, remain a long way from traditional manufacturers: Tesla only sold 499,550 cars in 2020, a long way from Volkswagen, for example, and its 11 million vehicles sold in 2019.

But Tesla is benefiting from investor enthusiasm for electric vehicles and the fact that it has managed to make money for five consecutive quarters, which allowed it to enter the prestigious S&P 500 index in December.
