Speed and Length
According to Einstein, Speed reduces length, and when a body reaches the speed of light it loses its volume or joins the infinity. Then every planet,Moon,or Star is speeding. Does it mean that all of them are losing in size?

Great question — you’re touching on ideas from Special Relativity, but there’s a key misunderstanding to clear up.
1. Does speed reduce length?
Yes — but only under specific conditions.
In Einstein’s theory, something called length contraction happens when an object moves at very high speed relative to an observer (close to the speed of light). The faster it moves, the shorter it appears in the direction of motion.
But this effect is:
- Only noticeable at speeds close to the speed of light
- Dependent on the observer’s frame of reference
2. What about planets, moons, and stars?
Planets, moons, and stars are indeed moving — but their speeds are tiny compared to the speed of light.
For example:
- Earth orbits the Sun at ~30 km/s
- Speed of light ≈ 300,000 km/s
That’s only about 0.01% of light speed.
👉 At such low speeds, relativistic effects are negligible, meaning:
- No measurable shrinking
- No loss of volume
So:
No — planets and stars are NOT shrinking in any meaningful way.
3. Does anything “lose its volume” at light speed?
This is another misconception.
- Objects with mass cannot reach the speed of light (this is a core result of relativity)
- As speed increases:
- Length contracts
- Time slows down
- Energy required grows enormously
But:
❌ Objects do not literally become zero size or “infinite”
❌ They do not disappear or lose volume completely
4. Why the confusion?
Because the equations show that:
- As velocity → speed of light
→ contraction becomes extreme
But this is a mathematical limit, not something physical objects actually reach.
Simple analogy
Think of it like approaching a wall:
- You can get closer and closer
- But you never actually pass through it
Similarly:
- Objects can get closer to light speed
- But never reach it
Bottom line
- Yes, speed can cause length contraction
- But only at speeds near light speed
- Planets and stars are far too slow for this to matter
- Nothing with mass actually reaches light speed or loses its volume
If you want, I can show you the actual formula for length contraction and how tiny the effect is for Earth — it’s surprisingly small.

KR Reduction in size is only due to perception from distance and angle or break away or else all had to enter the black hole grave yard and exit to be manifested again KR IRS 25326
