Did Einstein and Planck work together?

Max Planck discovers Albert Einstein In 1905, Einstein lacked both a PhD and a university teaching position. However, Planck almost instantly supported Einstein’s relativity theory, and in part through Planck’s backing, Einstein became a key figure among the scientific community.

What did Einstein find about the relationship between time and space?

As a result, he found that space and time were interwoven into a single continuum known as space-time. As he worked out the equations for his general theory of relativity, Einstein realized that massive objects caused a distortion in space-time.

What is the contribution of Max Planck and Albert Einstein in the current understanding of the particle nature of light?

Planck postulated that the energy of light is proportional to the frequency, and the constant that relates them is known as Planck’s constant (h). His work led to Albert Einstein determining that light exists in discrete quanta of energy, or photons.

What did Planck and Einstein contribute to the quantum theory?

Planck announced his findings in 1900, and in 1905, Albert Einstein used Planck’s quantum theory to describe the particle properties of light. Einstein demonstrated that electromagnetic radiation, including light, has the characteristics of both a wave and, consistent with Planck’s theory, a particle.

Why does curved space time cause gravity?

The curvature of spacetime (not just space) is responsible for gravity. Literally, near heavy objects, the “future direction” points slightly down. So anything that moves forward in time will find its trajectory pointing down slightly. This takes the form of downward acceleration.

How does gravity bend space-time?

Gravitational time dilation occurs because objects with a lot of mass create a strong gravitational field. The gravitational field is really a curving of space and time. The stronger the gravity, the more spacetime curves, and the slower time itself proceeds.

What is the size of the Planck time?

And roughly equal to 1.6 x 10 -35 m or about 10 -20 times the size of a proton. The Planck time is the time it would take a photon travelling at the speed of light to across a distance equal to the Planck length. This is the ‘quantum of time’, the smallest measurement of time that has any meaning, and is equal to 10 -43 seconds.

Why is the Planck scale important to special relativity?

On the Planck scale, simple ideas about time and space break down. However, the Planck units appears to give absolute scales of length and time. This poses important challenges for Special Relativity, as this page explains, following a brief introduction to the Planck scale.

How do you calculate Planck time from Schwarzschild radius?

Divide both sides by E: Multiply the above result by the Schwarzschild radius, then do some algebra to get the Planck length (x with a sub p): To get the Planck time (t with a sub p), take the Schwarzschild radius and divide it by c: Shall we call the above result the Schwarzschild time?

Why is the speed of light on the Planck scale?

The speed of light c is the natural unit that relates time and space. G is the constant of gravity, and h is the constant of quantum mechanics. So the Planck scale defines the meeting point of gravity, quantum mechanics, time and space.
