Which science-related photos are hard to believe but are real?

 Some of these photos will make you doubt their validity! Look at the goods, they are special!

• 1. Cut cancer

This cancer cell was opened using an ion beam. The beam blew up part of the cell to reveal a cross section and cut a triangular shape into the surface of the silica substrate on which it rests. The technique, called ion beam milling, allows researchers to look inside cancer cells in unprecedented detail.

• 2. A high-performance boat

This boat-shaped particle is 30 micrometers long and can propel itself by chemical reaction. The researchers 3D printed the particle and covered it with metal. This catalyzes a reaction in the hydrogen peroxide solution the particle is in, to produce a gas that pushes it.

• 3. Pollution and corona

Monkeys in Malaysia hold a medical mask. Protective clothing has become a part of daily life for many amid the coronavirus pandemic. Environmentalists fear that disposable items could contribute significantly to plastic pollution.

• 4. Clownfish

An embryonic clownfish (Amphiprion percula) grows inside its egg. These remarkably detailed images were captured on days one, three, five and nine of its development; the first was taken hours after fertilization. Photographer Daniel Knop won second place in the Nikon Small World photomicrography competition.

Is astrology a real science?

 Astrology is called Pseudoscience.

For example: Let’s take Solar eclipse and see what Astrology and Astronomy say about the same.

Solar eclipse :

Scientific explanation: A solar eclipse occurs when the moon gets between Earth and the sun, and the moon casts a shadow over Earth

Astrology’s take on Solar eclipse :

Let’s take Hindu astrology for example :

The Hindu mythology says Solar eclipse is caused by Asura Svarbhanu (Snake) who pierced the sun (according to rigveda)

According to Puranas (the post Vedic texts) : Svarbhanu disguised himself as a Deva to drink the Amrita (nectar of immortality). So, Lord Vishnu who was in his Mohini form beheaded the demon Svarbhanu - now he was split into two entities: Rahu and Ketu.

Rahu - the head of the snake or dragon , Ketu - the tail of the dragon. The head which is Rahu is in eternal cosmic journey around the Sun(he is chasing the Sun) and sometimes catches and swallows Sun and moon causing Solar and Lunar eclipses.

Rahu and Ketu are called the Lunar nodes.

Basically, Lunar node is the point at which the Moon, Sun and Earth are in the same plane.

Rahu causing a Solar eclipse:

In western Astrology this is called Caput Draconis and Cauda Draconis :

Rahu (the ascending node ) is called the Head of the Dragon and Ketu (the descending node ) is called tail of the Dragon.

9 Heavenly bodies of Indian Astrology :

Hindu astrology considers : the following as Nava Graha (nine heavenly bodies )

Sun, Moon, Mercury, Mar, Venus, Jupiter, Saturn, Rahu and Ketu ( Same as in Greek astrology)

Rahu and Ketu are considered as Shadow planets.

90 minutes of a day is allocated to Rahu and this time is considered as inauspicious time, it’s called Rahu Kaal.

People in India especially in the south, strictly observe the practice of avoiding starting any new work in Rahu Kaal.

Looks like ancients were trying to figure out things, with the limited technology they had and were successful to an extent in predicting solar and lunar eclipses using Lunar nodes as references.

But, they didn’t actually know what caused the eclipses. This is why it’s called Pseudoscience.

Pseudoscience is a set of beliefs which claim to be scientific, but it lacks the method or fails to explain a phenomena as accurately as Real science.

What are the most fascinating science facts?

One thing that has, and always will fascinate me is Einstein’s Special Theory of Relativity, or more specifically, time dilation.

You might be wondering; what the hell is time dilation?

Well, time dilation is the slowing down of time due to gravitational fields or traveling at extremely high velocities.

Basically, that means that the faster you move, the slower time flows for you relative to everyone else. The same thing will happen if you are near a significant source of gravity (such as a neutron star or black hole).

But, as I mentioned earlier, time dilation is relative. If you were on a ship traveling near the speed of light, everything would appear normal to you. You wouldn’t move in slow motion. To you it would appear that everything outside your frame of reference (which is your perspective at your velocity) is aging quicker.

This gives rise to an interesting thought to me. Think about all the motion you’re currently experiencing.

You may be moving in a car, or walking somewhere.

You are also moving along the Earth’s axis as it rotates.

You are also moving along the Earth’s rotational path around the Sun.

You are also moving around the rotational axis of the Milky Way, around the supermassive black hole Sagittarius A.

And finally, you are also moving towards the galaxy Andromeda, along with the rest of the Milky Way.

Picture all of those different vectors and degrees of motion you’re experiencing.

Now imagine how time must be flowing for us compared to say, an outside observer who is stationary relative to the Milky Way.

To me, that is certainly a fascinating fact.

What are the most fascinating science facts?

 Something that is truly incomprehensible are the voids that occupies the space between the visible matter in the universe. Some voids appropriately called “Super Voids” can be millions of light-yeas across.

For example; The ‘Boötes Void’ — It’s 250 million light years of almost NOTHINGNESS.

From this image it might not look that bad until you realize that almost all of the galaxies shown in the circle lie in front or behind it to date only 60 galaxies has been found within this void. A space that large could easily contain 10,000 galaxies when compared to other regions.

Just imagine if an alien civilization like our own exists on a planet within one of these galaxies the nearest neighbor would be tens of millions of light years away.. Even worse, if your planet is orbiting an intergalactic star, it’s a star or star system that has been ejected from its home galaxy and is now floating freely through the cosmos.

2.

Magnetars is a form of extremely magnetic neutron stars from around 400 kilometers, the magnetic field would strip you of all metallic objects such as your phone, watch, belt, and so on.

And if you got really close it would eventually start ripping out the iron in your red blood cells out of your body.

3. There’s a weird correlation between the distance and size of the Sun and our Moon because during a solar eclipse..

the moon almost prefectly covers the Sun but there’s really no physical reason why this has to be the case. The moon just happens to be 400 times smaller than the Sun, but the Sun just happens to be 400 times further from the earth than the moon…

Another object we can see with the naked eye is the Andromeda galaxy, and it looks like a little something like this

Photo; Lemmino / Youtube

But because Andromeda is so far away, we only see the very bright center of it. If we could see all of Andromeda our skies could look like this, every night;

It would be several times larger than the moon even though it’s 2.5 million light years away.

Could zombies exist according to science?

 If we are taking about a traditional zombie, the way they are often portrayed in movies (corpse raised by virus) then it's not possible.

An “engineered” zombie (corpse raised by some sort of nano machines) is theoretically possible.

A zombie like from the last of us (living person who’s behavior is changed) is possible.

A parasitic fungus that infects a unspected hosts and controls them with the goal of spreading more spores and infecting more hosts.

It already exists in nature. Cordyceps a fungus that infects ants and once an ant is infected, it loses control over it's body and force it to reach anything tall and burst open releasing the spore and infecting more ants. The fungus is literally called the “Zombie Fungus.”

There is also a parasite called Toxoplasma gondii that infects rats. Once a rat is infected it loses fear of cats, why cats? Because the only host where the parasite can reproduce is a cat.

Then the infected rat wonder around cats without any fear and gets eaten up and the parasite reproduces and continues the cycle.

• Contrary to the popular belief maximum oxygen on Earth comes from the oceans. (Atleast half of it)
• Marine organisms such as plankton, seaweeds and other photosynthesizer are direct contributor to the fresh air.

• There are more trees on Earth than stars in our galaxy.
• There could be about 100 billion to 400 billion stars in the Milky Way. Whereas according to 2015 journal Nature the number of trees around the world is about3.04 trillion.

• The Moon is lemon-shaped.
• Our natural satellite isn't actually spherical, as it seems to be, but, instead has flattened poles and bulges around the Equator, which makes is overall actual shape, lemo like.

• Mercury is still shrinking.
• In 2016, data from Mercury Surface, Space Environment, Geochemistry and Ranging (MESSENGER) aircraft revealed cliff-like landforms known as fault scarps. Because of their relatively small size, scientists are sure that they are newly formed (comparatively) and that the planet is still contracting.

• Babies are born with as much as 300 bones.
• As we grow old and taller many of our bones fuse together making the over-all count to be 206.

• The Apollo astronauts' footprints on the moon will probably stay there for at least 100 million years.
• Thanks to the absence of atmosphere on moon, there's practically no wind or water to wash these foot prints off.
