⚛️ Letzte Woche hatte mein Physik-LK die Möglichkeit an der Master Class zum Michelson-Interferometer an der @tubraunschweig teilzunehmen.

Selbst aufgebaut, kalibriert und gemessen bleibt sicher mehr hängen, als beim Demonstrationsversuch.
Neben der kompetenten Versuchsbetreuung gab es noch eine spannende Laborführung durch das LENA.

Ein sehr gelungener Exkursionstag. 👍

An #Interferometer is a scientific instrument that precisely measures changes in optical path length by causing light waves to interfere with each other.

In a typical setup, a beam of light is split into two, sent along different paths, and then recombined to produce an interference pattern.

Soo.... Crap... I'm running out of time.
Only hope I came up with is to get the #laser self mixing #interferometer working so I can accurately reposition with less than 1μm.... Got 9 days left 🙄

#LIGO goes to space: #ESA to proceed with LISA #gravitationalwave detector
ESA approved Laser Interferometer Space Antenna, or LISA. The #interferometer would follow the same basic principles as the ground-based LIGO (Laser Interferometer Gravitational-Wave Observatory) experiment that first detected gravitational waves, the hardware would be placed 2.5 million kilometers apart, making it sensitive to an entirely new range of astronomical phenomena.

The current age of #GravitationalWave astronomy is breathtaking. The next age will be mind blowing. Between #LISA and at least one large-scale ground-based #Laser #Interferometer, plus the #Pulsar Network and #Cosmic #Microwave #Background approaches, there will be coverage from the Planck scale/birth of the universe to the merging of #Sueprmassive #BlackHoles and even #Supernova explosions.

> The #Laser #Interferometer Gravitational-Wave Observatory (LIGO) is a huge installation measured in kilometers that is listening for wrinkles in space-time.

> Gravity causes #space-time to stretch — think back to the diagrams you’ve seen of a massive orb (a star or planet) sitting on a plane with grid lines drawn on it, the fabric of that plane being stretch downward from the mass of the orb. If you have two massive entities like black holes orbiting each other, they give off #gravitational #waves. When they collide and merge, they create a brief but very strong train of waves. Evidence of these events are what #LIGO is looking for.
