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.

 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

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.

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.
