Is Einstein's Theory of Relativity Flawed?

[A 15 year old]

Do Newtons laws apply? Not at high velocities, am I correct? Well, the Earth travels around the sun at 100,000 km per hour. Is that not high velocity? Well , it is said that Newtons laws don't apply at high velocities, or is size and proportion involved?

now I am not at all saying that everything in science is wrong by any means.

Why do planets move in circles around the sun? Gravity you might say. But that is not possible because *IF* in proportion the sun is not big enough to keep entire planets in orbit, in proportion to the gravitational pull on earth. Unless the sun has a huge magnetic core, which we *Think* is not possible based on theories. And if it is magnetic pull, why can't we detect such a huge force here on earth?

Absolute rubbish, where are you getting this from? It's hard to decipher what you actually mean, but let me assure you that as the first theory of gravity was in part designed to describe the motion in the solar system there is no conflict there.

in the grand sceem of things 100,000 km per hour is not high. it is slow

Per`pet´u`al
Adj. 1. perpetual - continuing forever or indefinitely

Yes, the term 'perpetual motion' can lead to confusion, but hre's a brief defintion:

how do you add a picture under your name? a little off subject.

Newton's laws are corrected by special relativity at high relative velocities, however in order to say any signifcant deviation from Newton's laws the relative velocities must be a signifcnt fraction of c (~300,000 km per second). 100km/h is not a significant fraction of c.

In accordance to the currently accepted theory, yes, it is constant. Whether if that theory is right or wrong, I am not allowed to say.

It's also according to experimental evidence.

Get a picture. Get a host to host it. Get the URL for it. Copy and paste it into the "Signature" portion in your settings.

thanks A 15 year old. ill try later

ok i understand that you should be able to back up what you said but some things really back up. take perpetul motion, some people think it is impossible but the Earth is moving around the sun with no energy going into it.

The Earth will not perpetually move around the sun. Energy is constantly being lost in the form of gravitational waves.

where is it at physics network?

 

[bino]

isnt gravity constant? it is pulling at the rate all the time mattering on your distance

Yes, Newton's laws apply for macroscopic systems. It's just that we have to use relativistic versions of those laws at high speeds. Of course, the relativistic versions are correct at low speeds too.

I am. Stop using Physics Forums as a crackpot chat site.
