Galileo Galilei
Galileo Galilei (1564–1642) was an Italian physicist, mathematician, astronomer and philosopher. He was a very important person in the Scientific Revolution —
at various times, people called him the father of modern observational
astronomy, the father of modern physics, and even the father of science.
He’s perhaps best known for his improvements to the telescopes and the
consequent observations he was able to make. Among his other achievements were the confirmation of the phases of Venus, the discovery of the four largest satellites of Jupiter (now named the Galilean moons), and the observation and analysis of sunspots. He also studied the motion of objects undergoing constant acceleration. Famously, he supported the heliocentric view of the solar system, which says the planets orbit around the sun, not the Earth. That was a tough stance to take in 1610, and he got into trouble for it with the Catholic Church, which in
1616 declared it “false and contrary to Scripture.” In 1632, he was tried by the
Roman Inquisition, found guilty of heresy, and forced to recant. He spent the
rest of his life under house arrest. Modern physicists can be glad that kind of
thing doesn’t go on much anymore.

when albert einstein meet charlie chaplin

Einstein: what i admire most about your art, is its universality. you don't say a word and yet, the world understands you.

Charlie: it's true, but your fame is even greater! The world admires you when nobody understands what you say.

🤣🤣🤣🤣🤣🤣🤣🤣 Charlie #forfun

Albert Einstein
Perhaps the most well-known physicist in the popular mind is Albert Einstein (1879–1955). Einstein, whose name has become synonymous with genius, made many contributions to physics, including the following:
✓The special and general theories of relativity
✓ The founding of relativistic cosmology
✓ The explanation of the perihelion precession of Mercury, which is the gradual rotation of the axis of the elliptical orbit of the planet
✓ The prediction of the deflection of light by gravity (gravitational lensing)
✓ The first fluctuation dissipation theorem, which explained the Brownian motion of molecules, which is the random jittery motion of small particles suspended in a fluid, which is caused by collisions with the molecules of the fluid
✓ The photon theory
✓ Wave-particle duality
✓ The quantum theory of atomic motion in solids
Einstein was the scientist who, on the eve of World War II, alerted President Franklin D. Roosevelt that Germany could be creating an atomic bomb. As a result of that warning, Roosevelt created the top secret Manhattan Project, which led to the development of the atomic bomb. In 1921, Einstein won the big one, the Nobel Prize, “for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect.” Einstein was affected by that absent-mindedness that scientists who habitually spend all their time thinking about their studies can suffer from. He’s said to have painted his front door red so he could tell which house was his. People joke that he once asked a child, “Little girl, do you know where I live?” And the little girl answered, “Yes, Daddy. I’ll take you home.”

Estimating accuracy😲
Physicists don’t always rely on significant digits when recording measurements. Sometimes, you see measurements that use plus-or-minus signs to indicate possible error in measurement, as in the following:
5.36 ± 0.05 meters
The ± part (0.05 meters in the preceding example) is the physicist’s estimate of the possible error in the measurement, so the physicist is saying that the actual value is between 5.36 + 0.05 (that is, 5.41) meters and 5.36 – 0.05 (that is, 5.31 meters), inclusive. Note that the possible error isn’t the amount your measurement differs from the “right” answer; it’s an indication of how precisely your apparatus can measure in other words, how reliable your
results are as a measurement.

Light is the fastest thing ever known besides mind(One’s mind can be faster than light joking). The speed of light in vacuum is 299,792,458 meters per second. Though in The Earth’s atmosphere the speed of light decreases still it is as fast as in vacuum. When passing through a diamond it slowed to less than half of it’s original speed. Through passing to a diamond it’s speed is 124,000,000 m/s (approximately 3.00×10 to the power 8 m/s). The light of speed is denoted as ‘c’.
The light of The Sun takes 8 minutes and 17 seconds to travel the distance to The Earth. If one could travel at the speed of light he/she could go around The Earth 7.5 times in a second or he/she could go to moon in 9 seconds approximately.
Since ancient time scientists and others want to know more about the light.
In 1667, the Italian astronomer Galileo Galilei stood two people on a hill at a distance of less than a mile, each holding a shielded lantern. One uncovered his lantern; when the second saw the flash, he uncovered his, as well. By observing how long it took for the light to be seen by the first lantern-holder (and factoring out reaction times), he thought he could calculate the speed of light. Unfortunately, Galileo's distances were too small to see a difference, so he could only determine that light traveled at least ten times faster than sound.
When Albert Einstein first predicted that light travels the same speed everywhere in our Universe, He essentially stamped a speed limit on it as 299,792 kilometers per second (186,282 miles per second) - fast enough to circle the entire Earth eight times every second.
Einstein's special ‘Theory of Relativity’ permanently tied mass and energy together in the simple yet fundamental equation-

E = mc2 (E is equal to M* C square).

This theory became the ‘Theory of the Century’.

One of the most famous scientist Sir Issac Newton also gave the theory of light but there ware loopholes in his theory. This theory is known as Newton’s corpuscular of light. That is-
1. Light consists of very tiny particles known as ‘corpuscular’.
2. These corpuscles on emission from the source of light travel in straight line with high velocity.
3. When these particles enter the eyes, they produce image of the object or sensation of vision.
4. Corpuscles of different colours have different sizes.
This little equation predicts that nothing with mass can move as fast as light, or faster. The closest humankind has ever come to reaching the speed of light is inside of powerful particle accelerators like the Large Hadron Collider and the Tevatron.
The first photo of The Earth and The Moon in a single frame was captured by Voyager-1 on 18 September 1977. Voyager-1 was launched on September 5, 1977 and after travelling approxmately 13 days it travelled the distance 7.25 million miles or 11.66 million kilometers with the speed of 62140 km/h. It can be imagined that the distance made by Voyager-1 can be covered in 1/20 second by the speed of light.

If two different events cannot be separated by time periods shorter than 10^−44 seconds, does this mean that an object requires at least that much time before it can travel from one location to another?

No. Two events absolutely can be separated by less than 10^-44 sec, there is no limit, and spacetime is continuous, not discrete. Or at least none of our successful theories assume that it is discrete.

10^-44 sec is the Planck time, the interval of time over which a system is so energetic that we expect classical gravity will not be accurate, and a quantum gravity will likely be needed. Gravitational fields will no longer have simple wave-like ripples, but instead the magnitude of the wave will be quantized.

There are 4 agreed upon fundamental forces in physics:
1. Gravity (a universal force that pulls and pushes on energy and momentum [according to Einstein, who generalized Newton’s notion that gravity pulls on mass], and which holds planets, stars, planetary systems and galaxies together). Gravity is associated with the gravitational field and a not-yet-observed particle called the “graviton”.
2. Electromagnetism (including both electric and magnetic forces, which pull and push on particles that carry electric charge, and holds atoms together). Electromagnetism is associated with electric and magnetic fields and with the particle of light, the “photon”.
3. The Strong Nuclear Force (a force that pulls and pushes on quarks, anti-quarks and gluons, and holds protons and neutrons together; a residual version of this force holds atomic nuclei together). This force is associated with the fields and particles called “gluons”.
4. The Weak Nuclear Force (a force which affects most known particles but is too weak to hold any known thing together; its main effect is to cause many types of particles to decay to other particles, and to allow production and observation of neutrinos.) This force is associated with the fields and particles called “W” and “Z”.
In addition, some physicists suggest that there is a 5th force which has not yet been observed:
5. The Higgs Force (an extremely weak force which some physicists expect to be present, now that a Higgs particle has been discovered and the existence of the Higgs field thereby confirmed.) The Higgs force would of course be associated with the Higgs field and particle.

How can the Sun have over 99.8% of the Solar System's mass even though the star system has so much materials and planets?

Because the sun is…just…huge. It's really, really big. There is so much matter that makes up the sun that it's actually horrifying to even think about. Even Jupiter, our biggest planet, is small and relatively lightweight compared to the large star we orbit. If you look up scale models of these things, it'll make your body hair stand on end. It sends chills down my body when I see the sheer difference in size.

The suns average density is 1.41g/cm^3 and the average density of the planets are as follows in g/cm^3:
1. Mercury: 5.4
2. Venus: 5.2
3. Earth: 5.5
4. Mars: 3.9
5. Jupiter: 1.3
6. Saturn: 0.7
7. Uranus: 1.3
8. Neptune: 1.6
9. Pluto: 1.9
Now, even though the planets are generally DENSER on average than the sun, they're not dense enough have enough matter in their little selves to make up more than 0.2% of the solar systems mass. Keep in mind, this is just the planets (yeah I know Pluto isn't a planet but I included it anyways) and there are also asteroids and comets and moons and such included in that 0.2%. Anyways, I just wanted to include this little snippet in here for anyone interested.
