Incredible Curiosities #5

1. You are looking at the past

Many centuries ago, physicist thought that the speed of light was infinite. However, that being proved impossible, the speed of light, c, was recognized as being 3 x108( 10 followed by 8 zeros)  meters per second. Then, this led to the conclusion that everything we see is actually from the past. Why?

Today's Scientific Joke #5

Two atoms were walking across a road when one of them said, "I think I lost an electron!" "Really!" the other replied, "Are you sure?" "Yes, I 'm absolutely positive." 



Explanation: When atoms have no electrons, they have positive charge, or are absolutely positive. 

( HA HA HA).

The Standard Model

The Standard Model is just like the periodic table. But… with particles. And keeping the weird names.

Higgs Boson 's Big Brother?

Scientists at the Large Hadron Collider, one of the world’s most important particle accelerator, have found signs of a new particle that could change all of our ideas on the Standard Particle Model.

White Holes

If black holes aren’t already crazy enough, imagine if you see one of these….

Today's Scientific Joke #4

There is a sign in Munich that reads, "Heisenberg might have slept here."


Explanation: According to Heinsenberg's Uncertainty Principle, you can not tell any particle's position or velocity down to quantum level.

Super Spiral galaxies found

A new type of monsters was spotted in our cosmos: the super spiral galaxies, enormous galaxies that can be as big as fours times the size of the Milky Way or 14 times its brightness.

1. My time is not your time

For many years, classical mechanics assumed that time was absolute to everybody, independently of their physical state (moving, standing still,...).However, Einstein came to prove these folks wrong. According to the principle of relativity, light is a constant velocity, c, and will always remain the same (in vacuum). Then, this would not follow the theorem of addition of velocities proposed by our friend Newton. This is how Relativity emerged. Through some calculations I will not cite now, it proved that, the bigger your velocity or the gravity you are experiencing, the slower time passes to you.

Antimatter -- our evil twins?

We all have heard about antimatter. It has been represented in movies and cartoons a few times -- an intergalactic villain who wanted to destroy the universe with antimatter! But is antimatter like the entertainment industries represent it? What are its properties?

Today's Scientific Joke #3

"A physics professor, who was teaching a graduate course on superstring theory, decided to add an essay question to this year's final exam. The instructions read, "Describe the universe in 400 words or less and give three examples." 


Explanation: The superstring theory says that are many universes and dimensions.

Life on Mars and cooperation in space

The first space mission that was born with the help of two space agencies, the European Space Agency and Roscosmos, the Russian Space Agency, travels with the promise of revealing some of the Red Planet’s secrets.

Women in science - we can do it!

On Tuesday, last week, the entire world celebrated the International Women’s Day. Have you ever stopped to think about women in science? If not, here is a list of 5 important females that made the difference in an area dominated by men.

50 Shifts of Red ( and Blue)

When we talk about waves, there are two important concepts you should remember: blueshift and redshift. But before we really get into these topics, we need to understand what the color spectrum is.

Today's Scientific Joke #2

“A photon checks into a hotel.

The bellhop asks, "Can I help you with your luggage.

It replies, "I don't have any. I always travel light." “

Explanation : photons are the “particles of light”, this is, the particles that make up visible light.

Incredible Curiosities #2

Welcome to Incredible Curiosities #2, your source for the most amazing facts about the Universe, life and everything else there is.

Where we came from, who we are

What if we could look at the origins of our own solar system, the place we live in?
Well, it seems like we are already doing so: technology has taken us to our distant past. 

Einstein Was Right!

No other discovery has been so impacting as that made by LIGO, the Laser Interferometer Gravitational-Wave Observatory. Researches were able to detect gravitational waves,  the final of Einstein's predictions on his General Theory of Relativity.But what are these waves, really? And why are they so important?

Today's Scientific Joke

Sometimes, I will post the so called "scientific jokes" on the blog so I can prove that us physicists and astronomers can actually have some humor.

But I can’t promise that you will laugh.

So, here it is:

“A neutron walked into a bar and asked, "How much for a gin and tonic?" The bartender smiled wryly and replied, ‘For you, no charge.’”

Explanation:

Neutrons, different from electrons and protons, that have negative and positive charge, have no charge.

Cosmic Sabbatical Year

  Would you accept being alone, away from family and friends, in an unkown and potentially dangerous place --- for one year? But I am not talking about a desert or a forest. Would you accept being one entire year in the vacuum of space? Well, a brave person did. And no, I am not talking about The Martian.
