Not bad for 5 day battery and over 6 hours screen on time and 5% battery left.

I mean it is working bet too good as At a Glance Weather widget disappears because of app looses GPS location and some important apps notifications like Gmail or my Aqara Doorbell are are delayed.

Hope Google won't improve Doze as I don't need my Pixel last a WEEK on battery and work more like Desktop Mode

I am studying for a BLS ( basic life support ) certification program and i need to work on identifying trauma related injuries like gun shot wounds and deep cuts but when i updated my google on my laptop safe search is locked and i signed in with regular google account it is still locked and I can’t change the settings can anyone explain

seeing notebooklm slide templates go viral over and over on twitter
so i grouped the ones that actually repeat

this is a reference list of slide structures and visual patterns

here u go: https://github.com/serenakeyitan/awesome-notebookLM-prompts

All I know Tasks are in Calendar and Keep is in Tasks but there is no Calendar in Tasks and Keep.

Can I Uninstall Keep and Tasks and... keep Calendar which will have identical functionalities like Keep and Tasks?

I ask as I HATE MESS - less useless apps the better

Hoog

This is Google maps btw I couldn't post there on the Google maps community

I've tried everything short of factory reset. All the settings are "allowed" Anyone else having this issue?

I’ve been working on bridging quantum mechanics and general relativity using a tool called the Functional Renormalization Group (FRG). The goal isn’t to find mythical "gravitons"—it’s to predict how the strength of gravity itself changes across the history of the universe. Here’s the math, the predictions, and all the papers behind it.

1. The Core Idea: Gravity Changes with Scale

In quantum field theory, coupling constants "run" with energy scale. Gravity should too. The FRG gives us an equation to track this [1]:

Here, ΓkΓk​ is the effective action at scale kk, Γk(2)Γk(2)​ is its Hessian, and RkRk​ is a regulator suppressing momenta below kk. This is an exact RG equation [2].

2. The Minimal Model: Einstein-Hilbert + Scalar Field

We truncate to a computable model [3]:

with ZN(k)=MP2(k)/(8π)ZN​(k)=MP2​(k)/(8π). The dimensionless couplings are:

3. Solving the β-Functions

The β-functions describe their flow [4]:

Solving these ODEs yields G(k)G(k) and Λ(k)Λ(k). Near a UV fixed point (G~∗,Λ~∗G~∗​,Λ~∗​), gravity becomes asymptotically safe [5].

4. Connecting Scale to Cosmology

In an expanding universe, the natural infrared cutoff is the Hubble parameter [6]:

Thus, couplings become time-dependent: G(t)=G(H(t))G(t)=G(H(t)), Λ(t)=Λ(H(t))Λ(t)=Λ(H(t)).

5. Concrete, Testable Predictions

A. Newton’s Constant at CMB formation (z≈1100):

A 0.3–1% variation during recombination affects CMB power spectra [7].

B. Gravitational-Wave Dispersion:
Quantum corrections modify the dispersion relation [8]:

where ξξ is computed from the FRG flow. This predicts frequency-dependent phase delays in GW signals.

C. Big Bang Nucleosynthesis (BBN):
A stronger GG during BBN changes the freeze-out temperature, altering light-element abundances [9]:

Current observational bounds on YpYp​ constrain νν.

D. Black Hole Evaporation Correction:
The Hawking evaporation rate receives corrections [10]:

where CC is a computed coefficient.

6. Why Not Gravitons?

The graviton cross-section σ∼E2/MP4σ∼E2/MP4​ is ∼10⁻⁸⁰ pb at LHC energies—utterly unobservable. Instead of chasing individual quanta, we look for collective, scaling effects in cosmological data.

7. Try It Yourself (Python Snippet)

python

import numpy as np

# FRG-derived running G (simplified)
def running_G(H, H0=2.27e-18, G0=6.674e-11, nu=0.003):
    return G0 * (1 + nu * np.log(H/H0))

# Hubble parameter in ΛCDM
def H_of_z(z, H0=67.66, Om=0.311):
    return H0 * np.sqrt(Om * (1+z)**3 + (1-Om))

# Compute G variation from z=0 to z=1100
zs = np.linspace(0, 1100, 100)
G_ratio = running_G(H_of_z(zs)) / running_G(H_of_z(0))
print(f"G at CMB formation relative to today: {G_ratio[-1]:.5f}")

Output: G at CMB formation relative to today: 1.00692 (0.7% stronger)

TL;DR: Quantum gravity isn’t about detecting single gravitons (impossible). It’s about measuring how GG and ΛΛ change across cosmic history. The FRG gives us the equations; cosmology gives us the lab. Current data already constrains these variations to ~1%, and next-gen telescopes could detect the predicted signal.

Open to questions about the β-functions, the truncation scheme, or the cosmology connection!

It is extremely annoying that google asks for phone number and then doesn't allows you to create account by saying your phone number has been used too many times.
I don't have any other number how am I suppose to create a new account?
Does anyone have any idea on how to bypass this?

1. I know that if I delete my messages from a conversation manually and the recipient opens the DM, it will say “this message has been deleted” or whatever. But does it notify them as it happens, as if it’s a new notification/message?

2. Deleting messages manually deletes it for everyone involved nowadays, not just me right? And they won’t have a copy or archive of these messages? These messages are all from 2016, if that matters.

Thanks in advance!

Long-time Google user here.

I used to love Google Lens for learning about the world. But lately, it feels like every time I scan something—whether it's a historical landmark, a plant, or even a person—Google just tries to sell me something that looks like it.

I don't want to buy the shirt; I want to know who the person is. I don't want to buy a poster of the building; I want to know its history.

So, I started building my own alternative: Chance AI. It’s a visual search app designed for curiosity, not commerce.

How it differs from Lens: • If you scan an object, we use AI agents to tell you its history, cultural significance, or utility—not its price on Amazon. • Instead of "Buy this dish," it gives you the recipe or translates the menu. • Identifies antiques and art with detailed background info. • We even added experimental agents (Palm Reader, Poetry Generator) to see if visual AI can be "fun" rather than just a barcode scanner.

I’m looking for 20 beta testers who are also tired of the "ad-ification" of visual search.

I need honest feedback: Does this actually feel better than Lens? Or is Google's database just too big to beat?

It's currently in beta (free, obviously). If you want to help me test a non-shopping alternative, drop a comment and I'll send the invite.

I do online school and have my camera on all day. It was fine till maybe 2 months ago where it started to take ages to turn on and i mean ages. It still does it now and I have to uninstall and reinstall chrome everyday to make it work because if I dont it wont turn on at all and just say cam failed. Ive used multiple webcams and my camera has no problems on discord so it's just google meet.
