SAEDNEWS: In Einstein’s world, no motion or stillness exists without a reference. Everything you perceive gains meaning only within the framework of an observer. You might feel stationary on a moving train—if your only point of comparison is another passenger in the same carriage.
According to the Science & Technology Desk of SaedNews, the faster we move, the slower time seems to pass for us, and distances appear shorter. In the fast-paced universe of particles and galaxies, even the passage of moments is relative.
🪐 Relativity reminds us that reality changes depending on our perspective. There is no absolute truth in motion — only an observer watching a universe in motion.
⏰ According to Einstein’s theory of special relativity, speed is always relative — never absolute.
🔹 This means that no observer or object in the universe can be said to be moving or at rest in an absolute sense. Every movement only has meaning relative to something else.
For example:
🔺 If you’re sitting on a train and throw a ball forward, the ball’s speed is low relative to you, but higher relative to someone standing outside.
🔺 Even the Earth is moving relative to the Sun, the Sun relative to the galaxy, and the galaxy relative to the universe — so absolute rest is meaningless.
🔸 The only absolute in relativity is the speed of light (≈ 299,792 km/s in a vacuum). No observer or object can surpass it or see it differently — light is the same for everyone.
🧠 In short:
⚡ Speed is relative, but the speed of light is absolute.
