The contribution of Scientists in unraveling mysteries of the universe and its constituents has been tremendous and greatly remarkable. Discoveries made by the scientists over the years have helped us a great deal in understanding both micro and macro cosmos. The discoveries, such as Planck’s constant and natural unit of light, have opened the Pandora’s Box around us to reveal other facts as well. Here is a list of top 10 mind blowing facts about Universe that will literally surprise you…

Black holes aren’t black

They’re very dark, sure, but they aren’t black. They glow, slightly, giving off light across the whole spectrum, including visible light. This radiation is called “Hawking radiation, after the former Lucasian Professor of Mathematics at Cambridge University Stephen Hawking, who first proposed its existence. Because they are constantly giving this off, and therefore losing mass, black holes will eventually evaporate altogether if they don’t have another source of mass to sustain them; for example interstellar gas or light.

The faster you move, the heavier you get

Do you want to fool yourself by increasing your weight in a short span of time? If you think it is not possible, physics have the answer. When you are running really fast, the body will show more weight. But you have to run that fast, nearing to the speed of the light. Here goes the explanation. The relativity theory points out that mass is equivalent to energy. When you give energy to an object which is moving closer to the speed of the light, the extra energy will turn as mass. In effect, the object will show higher mass.

All the matter that makes up the human race could fit in a sugar cube

Atoms are 99.9999999999999% empty space. If you forced all the atoms together, removing the space between them, crushing them down, a single teaspoon or sugar cube of the resulting mass would weigh five billion tons; about ten times the weight of all the humans who are currently alive. Incidentally, that is exactly what has happened in a neutron star, the super-dense mass left over after a certain kind of supernova.



There are an infinite number of mes writing this, and an infinite number of yous reading it

According to the current standard model of cosmology, the observable universe – containing all the billions of galaxies and trillions upon trillions of stars mentioned above – is just one of an infinite number of universes existing side-by-side, like soap bubbles in a foam. Because they are infinite, every possible history must have played out. But more than that, the number of possible histories is finite, because there have been a finite number of events with a finite number of outcomes. The number is huge, but it is finite. So this exact event, where this author(me) writes these words and you read them, must have happened an infinite number of times.

The fundamental description of the universe does not account for a past, present or future

According to the special theory of relativity, there is no such thing as a present, or a future, or a past. Time frames are relative: I have one, you have one, the third planet(anyone exist in universe) has one. Ours are similar because we are moving at similar speeds. If we were moving at very different speeds, we would find that one of us aged quicker than the other.

Our Universe is Rapidly Expanding

It is proved by scientific theories that the universe is constantly expanding. It is expanding at a decent pace and it is believed that galaxies will evaporate in the coming 10^19 to 10^20 years. It has been learnt from a number of theories by different Physicists worldwide that only White Dwarfs (a type of star) would be able to survive as their lifetime is more than 10^32 years.

Relativity Makes Space Travellers Younger

Both velocity and gravity have an effect on the speed of time; the higher they are, the slower time passes. Astronauts aboard the International Space Station (ISS) (who are in reduced gravity compared to people on Earth but travelling at increased speed around it) experience time more slowly, at a rate of roughly 1 second ‘lost’ every 747 days.



Electrical force is about a billion-billion-billion-billion times stronger than gravitation.

If you were standing at arm’s length from someone and each of you had one percent more electrons than protons, the repelling force would be enough to lift a weight equal to that of the entire earth!

Light waves don’t always move in straight lines

It is generally believed that light waves only move in straight lines. However, as per the recent research in 2010 using computer controlled hologram, it has been proved that light, too, can get twisted into knots. According to the study, when light passes through the hologram, it twists into different shapes, producing multiple knots.

All Matter is Just Energy

It’s true—matter and energy are just two sides of the same coin. In fact, you’ve known this your whole life, if you’ve ever heard of the formula E = mc2. The E is for energy, and the m represents mass. The amount of energy contained in a particular amount of mass is determined by the conversion factor c squared, where c represents—wait for it—the speed of light.
