What are the most fascinating science facts?

 When we would get into a very fast spacecraft and speed up, we would still observe the speed of light to be exactly the same. If we move towards the source light will not speed up, if we move away from the source light will not slow down. It will remain exactly as it is.

When we are at fast speed and use a light clock to measure time (by bouncing a photon between two mirrors) we would see exactly the same speed, each bounce would be identical.

Yet when we look from outside our spacecraft, for example from earth, we would see that the clock runs slower.

When we would travel at nearly light speed we would see that time seems to have stopped from the perspective from the outside observer.
And for us the first picture still applies, we observe only straight bounces, each indicating the same time frame.

When we would travel at exactly light speed time would stop for us.
There would be no bounce between the mirrors anymore.

More on this subject on the wiki on: Time dilation

Now suppose we are travelling on a photon which was send out shortly after the Big Bang. It would have travelled over 13 billion years and we would only observe it right now. Before that it just travelled through empty space and from the perspective of the photon it would be the moment it was generated. Time stopped right after it. So while it travelled 13 billion years we can also say it's not even a millisecond old.
The only way we as outside observers would know that it's this old is because it's extremely red-shifted, an indication the source is moving away from us at high speed. Check out Cosmic microwave background

And here we are. Sitting looking at the stars. We see the light of stars that might not even be present anymore.
The light from the Andromeda Galaxy travelled some 2.5 million years to reach us:

And yet when the photon hits our eye it does this the exact moment that it left the star, from the perspective of the photon that is. We are looking at the past and present at the same time. And that's really odd.

• 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.

What are some strange but fascinating scientific experiments?

 A small team of researchers from Spain and Mexico made a discovery, almost by accident, which

was later published in the renowned journal

Physics Review Letters .

Thousands of cubes randomly poured into a glass align themselves perfectly when the mixture is subjected to "oscillating rotation," that is, alternately accelerated clockwise and counterclockwise.

The researchers poured 25,000 plastic cubes into a transparent cylinder. They then tested various shaking techniques to determine which resulted in the highest compaction of the cubes.
They found that alternating rotation (left-right-left-right) worked best. However, the individual rotations had to be performed at high speed.
This caused the cubes to align themselves from top to bottom, forming concentric circles in each layer.

At an acceleration of 0.52 g, the pile of cubes reached its maximum density after 10,000 alternating angular impulses.
This seems to work significantly better than a simple "jerking," because at a state of medium density, the latter causes the cubes to wedge themselves together and remain stuck.
If the rotational impulses are too slow, the compaction and alignment of the cubes could potentially take years.

The researchers now hope that their findings will open up a potential new way to compact materials during the manufacturing process.

 Trees go to sleep too

Other plants open up and close from day to night, and trees do something similar. Scientists measured that trees shrink by 10cm at night and regain it's height after sunrise.

Time Crystals

Something that sounds like it came straight out of Rick and Morty is apparently real. Regular crystals are repeated patterns of atoms or molecules-in space. A time crystal has a pattern like a regular one, but it flips to another one, then flips again, forever.

Genghis Khan Had a Few Children

It's well known that the Asian ruler had a large harem and that he slept with thousands of women. He had so many children that today, 8% of Asian men are direct descendants of him. That's 16 million people!

The Earth Used To Be Purple

Yep. Chlorophyll, the stuff you'll find on plants, reflects green, resulting in green plants. Earlier in Earth's history though, microbes in plants used retinal instead, which reflects red and blue, causing a purple hue.

Toasting Using Lightning

Yeah, lightning. That thing that strikes in thunderstorms. If we could harness the energy from it, a single bolt of lightning could cook 100,000 pieces of toast.

Strongest Organism Ever?

What is the strongest living thing in existence? The Rock, Shaq, Thanos? Wrong. Gonorrhea bacteria is. They can pull 100,000 times their body weight, which is equal to 22 million pounds for humans. They do that by using a substance called pili to attach to other things.

We Are All Snakes

Okay not really, but the average human does shed 40lbs of skin in their lifetime.

Antimatter Is Dangerous And Expensive

Antimatter is (obviously) the opposite of regular matter. Instead of protons, neutrons, and electrons, there are antiprotons antineutrons and antielectrons (also known as positrons). When matter and antimatter come together, you get an explosion. If a 1kg piece of antimatter crashed into Earth, the energy released would be enough to melt 220,000,000,000 pounds of granite. Don't worry, we could never afford that much antimatter, since it cost $62.5 trillion to make a gram of it.
