15 interesting facts from the world of physics

Undoubtedly, physics is a very interesting subject of study. We offer 15 interesting facts from the world of quantum physics.

Want to know more interesting things? A physics tutor will help you with this.

1) The Eiffel Tower is increasing in height

Yes, this truly amazing phenomenon can be explained not so much by quantum physics as by physics. It turns out that the Eiffel Tower is up to 15 cm higher in July and August, due to the fact that it is made of steel, which has a high coefficient of thermal expansion.

2) The speed of light is always constant.

It is so indeed. Unfortunately, you can meet people who say that the speed of light is not constant at all, but this is not true. The speed of light is always constant.

3) Neutron star is the densest in the world

A neutron star is a supernova remnant and is currently the densest substance known.

4) The largest machine in the world is the Large Hadron Collider

This is actually quite interesting information.Well, the largest machine in the world actually comes from the world of physics, and it is the huge hadron collider. Interestingly, it is located in both France and Switzerland, and its circumference is as much as 27 km!

5) Quasars are the brightest objects in the Universe

The quasar is by far the brightest object. In general, scientists suggest that quasars are propelled by the energy of accretion disks orbiting supermassive black holes.

6) Tonic glows blue in ultraviolet light

However, it is worth emphasizing that this only applies to tonics that actually contain quinine. By the way, this is a fun way to really differentiate real tonics from each other.

7) Where do the colors of the sky come from?

We look at the sky and see colors. It seems normal, but where do these colors actually come from? After all, air has no color. A phenomenon known as Rayleigh scattering is responsible for the formation of colors. In other words, it is a scattering phenomenon of particles smaller than the wavelength of the scattered light.

8) Can a supernova be super-luminous?

Yes, sure. Interestingly, a supernova explosion can be as bright as a hundred billion stars.

9) When was the last supernova observed in the Milky Way?

In 1604. However, this does not mean that you will no longer be able to see a supernova. In fact, it is so bright that it can be seen from distant galaxies.

10) Can anything other than a black hole form from a massive star?

Of course, although until recently this was not such common knowledge. However, massive stars can also form magnetars under certain conditions. What is this? Well, magnetars are neutron stars with a very strong magnetic field.

11) Which star is the smallest in size?

It will be a neutron star.It differs in that it has only 1-2 solar masses.

12) Which stars have the longest life?

Interestingly, small stars live the longest in the Universe. Small red dwarfs actually emit very little energy. So they actually burn out very slowly.

13) What is the source of the most powerful energy in the Universe?

Well, basically the Big Bang comes first. However, besides it, it is necessary to mention the gamma-ray flash. Most likely, it was formed as a result of a star breaking through a black hole.

14) Is there a white hole?

Only hypothetically.

15) Drinking through a straw is a good example of using atmospheric pressure

By drawing air from the tube into our lungs, we lower the air pressure in it, then atmospheric pressure “pushes” the drink back and it flows into our mouth.
